Abstract: A closure device to be inserted at least partially through a blood vessel wall aperture in a blood vessel wall, having at least two metal petals that can be inserted through the blood vessel wall aperture and into the lumen of the blood vessel. The petals are structured to prevent withdrawal through the blood vessel wall aperture when the length of the petal is generally aligned with the blood vessel wall. The metal petals have alignment features that tend to urge them into alignment relative to each other. The closure device includes a metal expansion member that is alterable from an unexpanded state to an expanded state. A bioabsorbable tensioning member interconnects the petals and the metal expansion member and is securable to the metal expansion member.

Abstract: A closure device to be inserted at least partially through a blood vessel wall aperture in a blood vessel wall. The closure device includes at least two parts, an internal part and an external part. The internal part is adapted to be extended at least partially through the blood vessel wall aperture and into the lumen to at least partially block the blood vessel wall aperture. Each of the internal part and the external part consists essentially of a metal that biodegrades within a living being in a period of time that permits biological repair of the blood vessel wall in and around the blood vessel aperture.

Abstract: A coaxial guide catheter to be passed through guide catheter having a first lumen, for use with interventional cardiology devices that are insertable into a branch artery that branches off from a main artery. The coaxial guide catheter is extended through the lumen of the guide catheter and beyond the distal end of the guide catheter and inserted into the branch artery. The device assists in resisting axial and shear forces exerted by an interventional cardiology device passed through the second lumen and beyond the flexible distal tip portion that would otherwise tend to dislodge the guide catheter from the branch artery.

Abstract: A guidewire converter for use in intravascular procedures along with a guidewire. The guidewire converter includes an elongate tubular structure defining a lumen having an inner diameter and a first outer diameter. The inner diameter of the lumen is sized to receive the guidewire for intravascular procedures. The guidewire converter includes a locking mechanism coupled to the elongate tubular structure that has a second outer diameter that is less than or substantially equal to the first outer diameter. Operation of the locking mechanism releasably secures the elongate tubular structure to the guidewire.

Abstract: A device for application of energy within a tubular bodily structure including an optical fiber couplable to a source of laser energy and a guidewire tip. The optical fiber has a laser emitting portion remote from the source of laser energy and a distal end. The guidewire tip is operably secured to the optical fiber and extends distally outwardly away from the distal end of the optical fiber. The guidewire tip assists in advancing the device through the tubular bodily structure.

Abstract: A sealing device for sealing punctures in blood vessel walls including a flange connected to a flexible stem having an expansion portion in it. The flexible stem is adapted to be accommodated inside a delivery tube. The delivery tube further includes a hand-hold for ease of handling. The sealing device may further include a loader and a cutter. The flange and flexible stem are preferably constructed of a biodegradable material that has a tensile strength, rigidity, memory and other physical qualities similar to medical grade silicone. The resilient transverse expansion portion expands when deployed beyond the delivery tube in the tissue tract to create a frictional interface with the interior surface of the tissue tract to resist displacement of the flexible stem from a desired location in the tissue tract. The flexible stem also includes a flange at the distal end of the flexible stem to seal the puncture when the flexible stem is deployed.

Abstract: An abdominal tissue support for supporting excess abdominal adipose tissue away from the femoral crease to facilitate the maintenance of a sterile field for femoral puncture procedures. The abdominal tissue support may generally include a waist belt, at least one support apron affixed to the waist belt and a strap arrangement. The abdominal tissue support may also include a movable support apron slidable along the length of the waist belt. The strap arrangement may be securable at a patient's shoulders or to a fixture located near the patient's head.

Abstract: A catheter to be passed over a guidewire, including a screw portion with a cylindrical hollow shaft and a helical thread portion extending outwardly from the hollow shaft. The screw portion is secured coaxially to a tubular portion formed from a substantially rigid material. The tubular portion has, along a portion of its length, at least two slits having a pattern geometry that limits torsional displacement. The catheter also includes a hub having a lumen joined substantially coaxially to the tubular portion.

Abstract: An endovenous laser fiber optic member for endovenous laser therapy of peripheral veins of the body including a heat resistant insulative tip shield covering the distal end of the laser fiber optic. The tip shield may have echogenic qualities to increase ultrasound reflectivity. The tip shield also improves deflectability of the distal end and acts as a thermal break.

Abstract: An endovenous laser fiber optic member for endovenous laser therapy of peripheral veins of the body including a flexible heat resistant tip shield covering the distal end of the laser fiber optic. The tip shield has an irregular surface to increase ultrasound reflectivity. The tip shield also improves deflectability of the distal end and acts as a heat sink and heat energy dissipater.

Abstract: A hemostatic dressing for applying a hemostatic material such as lyophilized thrombin to a wound. The wound dressing includes an impermeable backing material and a sealing member to provide a seal against the skin. The wound dressing enables the application of pressure in order to seal the sealing member against the patient's skin to the wound without the need for attendance by a health care professional. The seal may be applied by a compressive band or by application of a pressure sensitive adhesive. The wound dressing creates a sealed localized procoagulation environment to facilitate the formation of a clot initiated by the presence of substantial quantities of externally supplied lyophilized thrombin or another dry coagulant.
