摘要： A delivery system for a medical device or other devices to be deployed within a biological body including a sheath having a longitudinal joint. The joint can be either resealable or non-resealable. The joint remains intact during delivery of the medical device, thereby facilitating accurate delivery of the medical device. During removal of the sheath, the joint is separated, thereby permitting the sheath to be peeled from the medical device while maintaining the position of the device. The delivery system allows a single operator to deploy the medical device and remove the sheath.

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： 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 guide wire and is deployed within the patient's vasculature as the guide wire 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 guide wire 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 system used in a blood vessel when an interventional procedure is being performed in a stenosed or occluded region, which is capable of enabling a support device and filter supported thereon, to be inserted into the blood vessel and to cross the stenosis therein in a low profile without a sheath extending thereabout. The filter is adapted to filter the blood in the blood vessel. The system is further capable of enabling the support device and filter to be positioned distal to the interventional procedure site, and to be activated to expand at the distal location so as to enable the filter to capture any embolic material that may be created and released into the bloodstream during the interventional procedure. The system is also capable of enabling the support device and filter to be activated to contract to a return profile for enabling the filter to retain the embolic material captured therein and the removal of the support device and filter from the blood vessel. The system includes a filter, adapted to be deployed distal to the interventional procedure site, and to pass blood therethrough and capture embolic material which may be released into the blood in the blood vessel during the interventional procedure. A support device is adapted to support the filter, and to retain a low profile so as to enable the filter to be inserted into and cross the stenosis in the blood vessel, to a position distal to the interventional procedure site, without a sheath extending about the filter and the support device. The support device is further adapted to deform for expansion thereof into open position to enable the filter to capture embolic material, and to enable the collapsing thereof to retain the embolic material captured in the filter, and to enable removal of the support device and the filter. The system also includes a mechanism, connected to the support device, adapted to be activated so as to enable the support device to deform for expansion thereof.

摘要： The present invention is directed to a guidewire having an elongate core member with a proximal section and a distal section. The distal section has at least one tapered segment, wherein the elongate core member tapers distally to a reduced diameter. Preferably, the tapered segments of the distal section of the elongate core member are marked with radiopaque markers to indicate where a tapered segment begins or ends. A proximal coil having a rectangular cross section and at least one distal coil having a round cross section are disposed around at least a portion of the distal section of the elongate core member. The proximal end of the proximal coil is attached to the distal section of the elongate core member. The distal coils can be made of a material that is radiopaque or non-radiopaque. If one of the distal coils is radiopaque, it may be made from a radiopaque material or it may be made of a hollow tube of non-radiopaque material that is filled with material that is at least partially radiopaque. The proximal end of the distal most coil is attached to the distal end of the proximal coil, and the distal end of the distal most coil is attached to the distal section of the elongate core member.
