Definitions
- the invention relates to a compression sleeve for local U sheathing of a blood vessel or a venous valve area according to claim 1.
- a possible treatment of these symptoms is carried out with the help of support stockings, which enclose the leg as a whole, build up a counter pressure to the blood pressure and thus relieve the tissue in the leg.
- the functionality of the body's own venous valves is not restored.
- veins and venous valves For a sustainable or preventive treatment of varicose veins, however, the maintenance or restoration production of the functional ability of the veins and venous valves of particular importance. Ideally, avoiding dilation of veins or venous valves should already start in the dilated tissue, preferably by reinforcing the tissue.
- the object of the invention is to propose a compression cuff in the form of a support cuff which can be implanted without severing the blood vessel to be supported and which is basically suitable for rapid growth with the tissue of the blood vessel.
- the compression sleeve essentially consists of a flexible mat made of a biocompatible material (e.g. titanium, nickel-titanium alloy alloys). This mat is used to coat a blood vessel locally, preferably in the area of a tissue weakening or a venous valve area.
- a biocompatible material e.g. titanium, nickel-titanium alloy alloys.
- the compression sleeve as a mat is a surface component.
- the blood vessel does not have to be cut through beforehand, as in the case of tubular support cuffs, but instead takes place in a particularly advantageous manner by simply wrapping the blood vessel through the mat.
- the compression additional means which ensure that the wrapping is retained, ie prevent a compression cuff applied to the blood vessel from loosening afterwards.
- These means are preferably either hook mechanisms, clips (each separately or worked out of the mat) or also an elastic pretensioning of the mat or a combination of the means mentioned.
- vasodilation can also result in an aneurysm, i.e. to develop into an extremely localized vasodilation, which tears open untreated from a critical load (pressure or stretching) of the tissue and leads to dangerous internal bleeding.
- the stroke is shown here as an example.
- the invention advantageously opens up a minimally invasive application of a sheath without a separation or puncturing (when stents are being applied) of the blood vessel, even in sensitive or difficult to access areas of the body.
- a further central feature of the invention relates to the nature of the mat, which is to be designed at least in such a way that it on the one hand ensures growth to the blood vessel wall and on the other hand ensures the deformability of the applied compression sleeve.
- the mat is structured as a mesh, mesh-like structure or with an open porosity.
- the mat is made of a shape memory material, e.g. a biocompatible shape memory alloy (preferably nickel-titanium alloys such as Nitinol).
- a shape memory material e.g. a biocompatible shape memory alloy (preferably nickel-titanium alloys such as Nitinol).
- Nitinol nickel-titanium alloys
- two possible application variants can be realized. Both versions are suitable for an advantageous minimally invasive application of the compression sleeve.
- the pronounced super elasticity of the shape memory alloys is used.
- a mat that has already been pre-bent in the rolled-up state can be bent open elastically for application, whereby it is placed around the blood vessel to be encased simply by appropriate elastic relaxation.
- a thermal shape memory effect of the shape memory alloy can also be used for the application of the compression sleeve in the context of the second application variant.
- the shape memory alloy is selected on the condition that it exhibits and maintains a predetermined deformation (body mat, condition A) at body temperature, preferably between 30 and 45 ° C, and on the other hand that it has an envelope temperature below (minus approx. 1 to 30 ° C) of the temperature range mentioned, which morphological transformation of the crystal lattice causes deformation of the material (unwound mat, condition B).
- Such a mat can be assembled in such a way that it is attached to a blood vessel in state B, ie below 30 ° C., the aforementioned transformation causing a predetermined deformation of the mat and thus the blood vessel enclosing the blood vessel (in state A).
- Dimensioning of the deformation and thickness of the mat of the compression sleeve takes place individually after the geometrical detection of the enlarged blood vessel and the deviation from the desired undamaged, ie unexpanded, blood vessel.
- compression of the vena saphena magna is necessary in the area where the vena saphena magna joins the vena femoralis (area of the cross) as soon as its diameter is greater than 6 mm.
- the compression cuff acts as an external stent or the aforementioned support cuff, which avoids dilation of the corresponding section of the vessel. If the vessels are already dilated, the stent rejuvenates the vessel to its original state. In this state, the functionality of a natural flap in the supported areas is guaranteed again.
- 1 is a mat of a compression sleeve with a plurality of uniform recesses lined up over the entire mat surface
- FIGS. 4 a to c three possible hook connection types for compression sleeves.
- FIGS. 1 to 3 each show a mat of a compression sleeve with webs 1 and cutouts 2. Furthermore, FIGS. 2 a and b and 3 a to f molded hooks 4, which, shown in FIGS. 4 a to c, engage in eyelets 3 (correspondingly shaped webs) in certain areas of the mat.
- Fig. 1 shows the mat of a compression sleeve with a uniform, almost square or diamond-shaped structuring. It is characterized by a uniform elasticity in the direction of the diagonals of the square structures, but a high rigidity in parallel to the webs, i.e. characterized by high dimensional stability. For this reason, a compression cuff structured in this way is only suitable for blood vessels that are only exposed to slight variable bends or strains (e.g. not for strongly pulsating main arteries). In contrast, the comparatively high dimensional stability when stabilizing aneurysms is expressly desired. Hook mechanisms are not shown (but possible) in FIG. 1, so that an applied compression sleeve of this type is only fixed in the mat by an elastic pretension.
- the mat can be produced from a biocompatible material by laser cutting or punching from a foil or sheet, alternatively as a wire mesh.
- FIGS. 2 a and b show two exemplary embodiments in which the structuring of the mat has a large number of cutouts of two different geometries which are alternately arranged over the entire mat surface.
- the webs are no longer aligned in only one direction, which results in increased flexibility in the direction of the webs compared to the embodiment shown in FIG. 1.
- the elastic stretch properties are approximately the same across the entire mat surface.
- the exemplary embodiments shown are also suitable for the sheathing of blood vessels which are exposed to a variable, if limited, bending or stretching.
- the means in this case include hooks 4, which after sheathing a blood vessel practically engage in any recesses that form the eyelets.
- the types of hook mechanisms of FIG. 2 a are shown in detail in FIG. 4 c, those of FIG. 2 b in FIG. 4 a in detail.
- FIGS. 3 a to f show the designs of compression sleeves individually designed with regard to a specific application.
- the exemplary embodiments disclosed here differ from the aforementioned in that they are structured differently in segments and the associated locally different elastic expansion behavior.
- FIG. 3 a shows a design with: a particularly finely branched structuring, the webs being curved in a serpentine or meandering manner and having no preferred orientation.
- this exemplary embodiment has a high degree of flexibility in all directions, the particularly high filigree nature of the webs additionally promoting rapid growth of the compression sleeve with the tissue of the blood vessel.
- a compression sleeve designed in this way is particularly suitable for the sheathing of often bending or stretching blood vessels such as strongly pulsating arteries or veins (arteries).
- FIGS. 3 b and c are based on similar design criteria, the structures being less filigree and the cutouts 2 being larger.
- 4b shows the quickly releasable hook mechanism 3 and 4 in detail.
- 3 b and c each show a compression sleeve for a preferably temporary use on blood vessels, for example for the stabilization of blood vessels during operations or healing processes.
- FIGS. 3 c to f represent compression sleeves on their mats in several areas are divided. Each of these areas has a specific task and has the required structuring design.
- the mats have two types of areas, namely cuff areas 5 and support areas 6.
- the cuff areas are used to fix the compression cuff to the blood vessel and therefore also have the necessary means (hook mechanisms 3, 4).
- support areas 6 are arranged, which only support the blood vessel and do not contribute to fixing the compression cuff.
- 3 d shows a structuring example for a compression sleeve with a support area with particularly high radial stiffness and particularly low axial stiffness.
- Blood vessel areas under the support area can practically not radially expand or contract after the webs have grown into the tissue material of the blood vessel.
- This embodiment is therefore particularly suitable for supporting and stabilizing the body's own valves such as venous valves.
- the high radial flexibility only slightly limits the axial extensibility of the blood vessel, so that the blood vessel is advantageously still suitable for compensating for a possible blood congestion by axially expanding the blood vessel and for preventing possible complications.
- 3 e and f show structuring examples for a compression sleeve each, which is fundamentally similar to that in FIG. 3 d.
- the serpentine-structured webs in the cuff regions 5 have a considerably lower amplitude, which considerably reduces the axial flexibility in favor of a radial flexibility.
- Areas of application for these exemplary embodiments can be found in particular in strongly pulsating blood vessels.
- 4 a to c show the hook mechanisms 3, 4 (means) explained in more detail on the basis of the preceding exemplary embodiments. In the form shown, they consist of appropriately shaped webs 1, hooks 4 hooking into appropriately shaped eyelets 3 and, if necessary, can also be locked there by bending. Depending on the application, the hooks can also be hooked into structuring areas that can be used as eyelets, even on the inside of the mat.
- Separate components or clips can also be used with the same effect as hooks.
