Definitions
- This invention is a vasoocclusive device. It is placed in the vasculature of an animal to form thrombus in a selected site such as an aneurysm or AVM.
- the device uses a central coil having thrombogenic fibers placed on the coil in a specified fashion. The coil will pass through the lumen of a vascular catheter and form a convolution when ejected from the catheter's distal end. .
- the fibers are attached to the coil and cooperate with the coil so that upon ejection from the catheter, the convoluted coil forms a shape in which the central region contains the majority of these fibers.
- Vasoocclusive devices are surgical implants placed within blood vessels or vascular cavities, typically by the use of a catheter, to form a thrombus and occlude the site.
- treatment of a stroke or other such vascular accident may include the placement of a vasoocclusive device proximal of the site to block the flow of blood to the site and alleviate the leakage.
- An aneurysm may similarly be treated by introduction of a vasoocclusive device through the neck of the aneurysm.
- the thrombogenic properties of the vasoocclusive device causes a mass to form in the aneurysm and alleviates the potential for growth of the aneurysm and its subsequent rupture.
- Other diseases, such as tumors may often be treated by occluding the blood flow to the tumor.
- vasoocclusive devices suitable for forming thrombus.
- One such device is found in U.S. Patent No. 4,994,069, to Ritchart et al. , the entirety of which is incorporated by reference. That patent describes a vasoocclusive coil that assumes a linear helical configuration when stretched and a folded convoluted configuration when relaxed. The stretched configuration is used in placement of the coil at the desired site and the convoluted configuration occurs when the coil is ejected from the catheter and the coil relaxes.
- U.S. Patent No. 5,226,911 to Chee et al. , describes a vasoocclusive coil with attached fibrous elements.
- the fibers are looped in a generally serpentine manner along the coil.
- the fibrous loops are affixed to (or looped through) the coil at spaced intervals along the coil.
- the use of multiple fibrous windings is noted in the patent but that use is said to involve placement of the fibers 180° apart on the circumference of the coil.
- Figure 1 shows a partial side view of a typical coil (expanded) made according to the invention.
- Figure 2 shows a partial side view of the inventive coil showing details of fiber attachment.
- Figure 3 shows a partial side view schematically depicting the attachment of multiple filamentary elements.
- Figure 4 shows a cross section, end view of the inventive coil showing placement of the filamentary elements.
- Figures 5A and 5B are fragmentary cross- sections of end sections of the inventive fibered coils.
- Figure 6 shows a plan view of the relaxed inventive coil after deployment.
- this invention is a vasoocclusive device and, in particular, it is a fibered coil.
- Figure 1 shows a length of the fibered coil (100). It is made of several components: a helical coil (102) , a first fibrous element (104) , and a second fibrous element (106) . The end of the coil may be sealed to form a cap (108) .
- the helical coil (102) is typically of a radiopaque material such as tungsten, tantalum, gold platinum, and alloys of those materials. Stainless steels are also suitable.
- various polymers, such as polyethylene, polyurethane, and the like as the coil material is also contemplated.
- the use of polymeric materials typically involves the use of known radiopaque fillers such as powdered tantalum, powdered tungsten, barium sulfate, bismuth oxide, bismuth carbonate, or the like.
- the coil may be from 0.2 to 100 cm in length or more.
- the diameter of the coil is from 0.004" to 0.015", typically from 0.008" to 0.012".
- the wire making up the coil is 0.0005" to 0.002" in diameter.
- the coil may be wound to have a tight pitch, that is to say, that there is no space between the adjacent turns of the coil, or it may have some space between adjacent turns.
- the first (104) and second (106) fibrous elements typically are bundles of individual fibers (5 to; 100 fibers per bundle) , but may be individual fibers.
- the fibers may be of a number of different thrombogenic materials.
- Suitable synthetic fibers include polyethylene terephthalate (e.g., DACRON) , polyesters, especially polyamides (e.g., the Nylons), polyglycolic acid, polylactic acid, and the like.
- Other less desirable synthetic polymers because of their decreased thrombogenicity, include fluorocarbons (Teflon) and polyaramids (Kevlar) . Natural fibers such as silk and cotton are also quite suitable.
- the fibered coil (100) shown in Figure 1 is in the general shape as found. in the catheter lumen.
- the coil (102) has been stretched to place the first fibrous element (104) and second fibrous element (106) close along the outer periphery of the coil (102) . This stretching lessens the overall diameter of the fiber coil (100) as seen by the catheter lumen.
- the multiple fiber elements are alternately looped along the coil. That is to say that the looping of the first fiber element (104) through coil (102) alternates with the looping of the second fiber element (106) through coil (102) .
- the fiber elements may be looped through the coil (102) as shown in Figures 1 and 2 or they may be tied at intersections with the coil (106) although, because of the interference between the knot end catheter offered by the knot, a mere looping is preferred.
- the end passage of the fibers through the coil desirably involves a knot. Only a pair of fibrous elements (104 and 106) are shown in Figures 1 and 2; multiple such fiber elements may be used, however. Additionally, it is quite desirable that the spacing of the fibrous elements as they cross the coil need not be equal.
- FIG. 4 A significant aspect of this invention is shown in Figure 4. That drawing, a cross-section view, shows that the various fiber elements (in this example, 104 and 106) occupy a small radial sector of the coil's circumference. Although, upon deployment, the various fiber elements will shift toward each other to a modest degree, the filaments must be placed in the same 90° quadrant (105) to attain maximum benefit of the invention. This quadrant is measured perpendicularly to the axis of the stretched coil.
- Figure 1 shows an end (108) on coil (102) .
- Such ends (108) are typically produced by heating the end of the coil (102) to melt a small section of the coil and form a closed end (108) .
- Figure 5A shows a close-up of the end (108) and the coil (102) .
- Figure 5B shows an additional variation in which the coil (102) encompasses a control wire (116) and an end cap (118) having a hole therethrough.
- a control wire (116) allows "ganging" of the coils or placement of a number of coils "nose-to-tail" within the catheter and therefore gives the attending surgeon the choice of using one or more coils without reloading the catheter.
- Figure 6 shows the shape of the coil (102) after it has been deployed from the catheter.
- the coil (102) encompasses an interior region (124) which has fiber passing through the region which is formed by creation of a secondary diameter (126) . This region
- the coils (102) discussed above are "preformed” so as to allow the coil (102) to assume the secondary diameter (126) shown in Figure 6.
- the patent to Ritchart et al . (U.S. Patent No. 4,994,069), discussed above, discusses a number of ways to preform such coils, e.g., by crimping the coil at various intervals.
- Another way to preform the coils, particularly when using the preferred platinum/tungsten alloy mentioned above is by winding the coil on a mandrel into the secondary diameter shown in Figure 6 and then modestly heat-treating the , consider claim law law
- the coil will retain sufficient flexibility to extend, in a linear fashion, through a catheter lumen.
- This device may be deployed in the same manner as are the coils described in the Ritchart et al or Chee et al patents discussed above.
- a vascular catheter is introduced into the bloodstream at a convenient site, often the femoral artery in the groin, and advanced to the site of concern. As has been noted elsewhere, these sites ore often in the cranial arteries but may be in any other site where occlusion is desired.
- Guidewires are typically used to direct the catheter to the desired site but blood flow is used to direct flow- directed catheters. Once the distal end of the catheter is at the site, the catheter lumen is cleared of guidewires and the like.
- the inventive coil is then introduced into the lumen, often with the help of a cannula to preserve the shape of the elongated coil until it enters the catheter lumen.
- a pusher typically similar in shape to a guidewire is then introduced into the catheter lumen to push the inventive coil along the interior of the catheter and out its distal end. Once the coil is safely in place, the catheter is removed from the body.
