    摘要: An embolic protection device for use in a blood vessel when an interventional procedure is being performed in a stenosed or occluded region to capture any embolic material which may be created and released into the bloodstream during the procedure. The device includes a filtering assembly having a self-expanding strut assembly and a filter element attached thereto. In one embodiment, the filtering assembly is attached to the distal end of a guidewire and is deployed within the patient's vasculature as the guidewire is manipulated into the area of treatment. A restraining sheath placed over the filtering assembly in a coaxial arrangement maintains the filtering assembly in its collapsed position until it is ready to be deployed by the physician. Thereafter, the sheath can be retracted to expose the filtering assembly which will then self-expand within the patient's vasculature. Interventional devices can be delivered over the guidewire and any embolic debris created during the interventional procedure and released into the blood stream will enter the filtering assembly and be captured therein. Other embodiments include filtering assemblies attached to an outer tubular member and inner shaft member which apply axial force to the distal ends of the assembly to either expand or contract the struts as needed.

    摘要: A deployment control system provides controlled deployment of an embolic protection device which may include a guide wire, an expandable filter attached to the guide wire near its distal end, and a restraining sheath that maintains the expanded filter in a collapsed position. The deployment control system includes a torque control device which allows the physician to torque the guide wire into the patient's anatomy and a mechanism for preventing the guide wire from buckling as the restraining sheath is being retracted to deploy the expandable filter. A recovery control system for recovering the embolic protection device includes an inner catheter which extends within a lumen of an outer recovery sheath in a coaxial arrangement. A distal portion of the inner catheter extends beyond another recovery sheath during advancement of the recovery system into the vasculature. The recovery sheath can be advanced over the inner catheter to collapse the expandable filter. The proximal ends of the inner catheter and recovery sheath include handle portions having snap mechanisms which hold the components together as the recovery system is being advanced into the patient's vasculature.

    摘要: A delivery system for an expandable filter device includes a dual lumen delivery sheath which has a lumen for receiving the expandable filter device and a lumen for receiving a primary guide wire. The primary guide wire is utilized to place the delivery sheath and expandable filter into the desired region of the patient's vasculature via an over-the-wire or rapid-exchange arrangement. The delivery sheath can be protracted over the expandable filter device to allow the filter to be deployed within the patient's vasculature at the desired location. The delivery system can be embodied in an alternative design in which the primary guide wire extends through a guide wire lumen located in an obturator which forms part of the expandable filter device. Again, the primary guide wire is utilized to maneuver the filter device into the desired area via an over-the-wire arrangement. A slit extending longitudinally along the length of the sheath facilitates the removal of the guide wire and delivery sheath from the patient's vasculature.

    摘要: A delivery sheath is provided for deploying a self-expanding intravascular filter. The sheath includes a stiff proximal portion which provides for good pushability and trackability through tortuous vessels and a soft, flexible, low profile, radiopaque distal tip for holding and delivering a deployable filter. The soft distal tip minimizes the formation of embolic particles that may be produced by contact between the sheath and an arterial lesion. The distal tip may be molded from a polymer containing radiopaque particles held in suspension and thereby provides for good visualization under fluroscopy.

    摘要: A guide wire having a damped force vibration mechanism which isolates vibrations or shockwaves which otherwise would be transmitted along the length of the guide wire to its distal end. The damped force vibration mechanism helps absorb some of the energy created during the exchange of a delivery catheter or an interventional device on the guide wire or any shock or force generated from an external source. The damped force vibration mechanism absorbs vibrations or shock which would otherwise act on medical devices attached near the distal end of a guide wire. The damped force vibration mechanism may consist of a reduced segment on the guide wire which can be made from a material such as superelastic or plastically deformable, biocompatible materials. The damped force vibration mechanism can have a relatively straight configuration or can have a wave-shaped form, or other shape which helps absorb vibratory motion.

    摘要: A wire stent having a preformed series of peaks alternating with valleys. The wire is formed from a malleable or resilient material and can be wound into a continuous helix. Each pair of peaks and valleys constitutes a wave. The stent has a number of waves per circumferential revolution such that the adjoining waves align off-peak to off-valley with one or more such adjoining waves being affixed to each other at the off-peak to off-valley locations. The waves can be welded at all locations or only at the circumferential revolutions at the proximal and distal ends of the stent, or intermittently, or in barber pole fashion or along one or more longitudinal axes.
