SUPPORT DEVICE FOR INTERVENTIONAL INSTRUMENTS

PRIORITY CLAIM

[00011 This application claims priortiy to United States Application Serial No. 61/073,634, filed June 18, 2008. The entire contents of the aforementioned application is incorporated herein by reference in its entirety.

FIELD OF THE INVENTION

|0002] The present invention relates to devices for the support, organization and improved stability of interventional instruments such as sheaths, guide wires, or catheters used during medical procedures.

BACKGROUND OF THE INVENTION

[0003] In the past, physicians' assistants and nurses are tasked with manually holding, organizing and supporting interventional sheaths, guide wires, and catheters during medical procedures. Currently, there are no devices that can be used by a physician to help maintain the instruments position within a patient's body and help support the portions of the instruments which are external of the patient's body on the operating table. In current interventional procedures, when a physician is performing the interventional procedure, the physician or the assistant must maintain manual physical control of an interventional instrument at all times. When the physician needs to perform other surgical tasks or actions, he or she must hand over and rely on the assistance of the operating room support staff to hold and organize the instruments during the interventional procedure. At all times during the intervention, the physician must manually, with his hands, keep the instruments in place and prevent the instruments to come into contact with contaminated surfaces. It would be desirable to possess a device that could support and organize interventional sheaths, guide wires, and catheters which will give physicians the freedom to step away from one of the mentioned instruments while simultaneously allowing assistants to complete more important tasks than holding the interventional instrument. Past arrangements have been cumbersome and a nuisance for physicians, and as such, the present invention allows the physicians to securely maintain instrument position both in and out of the patient without relying on medical staff. SUMMARY OF THE INVENTION

[0004] The present invention provides a support and stability device for interventional instruments including, but not limited to a sheaths, guide wires, and catheters, for use during medical procedures. The support device for interventional instruments comprises a base for securing the device to a surgical platform and holding member for engaging and securing an interventional instrument relative to the surgical platform.

The device is fastened in such a way that there is no motion of the device relative to the operating surface or platform and the patient. Additional methods of fastening the support structure to an operating surface can be utilized without departing from the spirit of the present invention. [0008] According to another aspect of the present invention, the device also serves as a means of preventing the instruments from moving and accidentally coming in contact with contaminated surfaces which could cause the instrument to become unsterilized, an undesirable accident during a medical procedure. In one embodiment, the base is meant to be fastened to a sterilized operating surface or platform in order to keep the instruments from coming into contact with an unsterilized surface. Additionally, the support device is fastened to an operating surface or platform in close proximity to the physician in order to keep the instruments within an arm's distance of the medical staff or physician. [0009) In an embodiment, the support device can be used with more than one operational instrument at once. The device, in one embodiment, has enough fastening support to simultaneously secure several sheaths, guide wires, and catheters at the same time.

[0010] hi an embodiment, the support device also comprises of multiple holding members further comprising at least one of a resilient instrument slot, a loose holding ring, or a graspable holder for securing instruments of differing sizes and shapes and for providing differing degrees of support that can be chosen based on the degree of support required to complete a medical procedure.

[0011] According to an aspect of the present invention, a support device is provided for use with an interventional sheaths, guide wires, or catheters to maintain sufficient control of said instruments. In one embodiment, the support device may include three different holding members for securing and organizing the instruments including a loose holding ring to loosely support any instruments, resilient instrument slots for securing multiple size instruments, and a graspable holder to provide enhanced control and guiding during the introducing of said instruments into the patient's body. The holding members can be used with several instruments at the same time or with one instrument to provide different securing options. In one embodiment, the invention can support more than one gauge or size of interventional wires, or different size sheaths or catheters.

[0012] In one embodiment, the loose holding ring serves as a rest and flexible containment for one or more instruments.

[0013] In another embodiment, the resilient instrument slots serve as a resilient securing means for various size instruments including varying gauges of wire.

[0014] In another embodiment, the graspable holder allows the physician to lightly secure and guide the instrument during interventions.

[0015] In another embodiment, the multiple holding members further comprises multiple resilient instrument slots independently spaced at any one of the lengths selected to fixedly engage and secure interventional instruments sized from .014", .018", or .035" inches.

[0016] In another exemplary embodiment, the graspable holder is located in the middle portion of the device. In another embodiment, the graspable holder further comprises an inner holding member of the graspable holder. [00171 In another exemplary embodiment, the graspable holder includes an inner holding member and a locking member to securely and fixedly lock the interventional instrument into said graspable holder.

[0018] In another embodiment, the graspable holder further comprises an inner holding member which is made of silicone compositions or polymers which provides moderate and sufficient frictional holding of the instrument but also allows the physician to move the instruments longitudinally through the graspable holder for simultaneously guiding the instruments into a patient's blood vessel during the intervention.

[0019] According to another aspect of the present invention, a method is provided for delivering an interventional instrument through a blood vessel of a patient, comprising; providing a support device comprising a base for securing said support device to a surgical platform and holding member for engaging and securing an interventional instrument relative to the surgical platform.

[0020] In one embodiment, a method is provided for delivering an interventional instrument through a blood vessel of a patient, comprising: providing a support device comprising a base for securing said support device to a surgical platform and holding member for engaging and securing an interventional instrument relative to the surgical platform, wherein said support device further comprises multiple holding members in multiple sizes and structures.

[0021] In another embodiment, a method is provided wherein the support device further comprises a loose holding ring, wherein said ring is circumferentially spaced to loosely and simultaneously engage and retain multiple interventional instruments.

[0022] In one embodiment, a method is provided wherein the support device further comprises a resilient instrument slot, wherein said slot is spaced to fixedly engage and secure an interventional instrument.

[0023] In one embodiment, a method is provided wherein said support device furthers comprises multiple resilient instrument slots.

[0024] The above descriptions are those of current embodiments of the invention. Various alterations and changes can be made without departing from the spirit and broader aspects of the present invention, which is intended to be limited only by the scope of the appended claims, which are to be interpreted in accordance with the principles of patent law including the doctrine of equivalents.
