摘要： A filter device is adapted to function as a guidewire, an exchange guidewire, and provide embolic protection during a procedure. The filter device includes a filter assembly that is either integral with or coupled to a guide member. The filter assembly includes a plurality of struts that expand outwardly to deploy a filter that collects or captures material flowing along the blood vessel within which the filter device is deployed. The plurality of struts are constrained by a restraining member or mechanism that prevents the plurality of struts from expanding or extending outwardly to deploy the filter. Cooperating with the restraining member or mechanism is an actuating assembly that is adapted to release the restraining member or mechanism and enable the filter to be deployed from the guide member. A capture catheter that cooperates with the filter device and substantially surrounds the filter during removal of the filter device.

摘要： Devices, systems and methods for retrieving clot material from a vasculature lumen are provided. In one embodiment, a medical device includes a handle, a catheter, a tether member and a clot retrieval element. The catheter extends from the handle and the clot retrieval element is configured to be positioned within a distal portion of the catheter with the tether member extending between the handle and the clot retrieval element. The clot retrieval element is configured to be deployed from within the catheter so that the catheter moves proximally relative to and separate from the clot retrieval element while maintaining attachment to the clot retrieval element via the tether member. Further, the clot retrieval element is configured to be pulled by the tether member to abut against a distal side of a clot with proximal movement of the tether member to pull the clot from the vasculature lumen.

摘要： Filters and method of manufacturing filters are disclosed herein. The filter has a substantially sack-like shape having a closed distal end and an open proximal end. The filter can be constructed from thin film. The filter material can be an organic or inorganic polymer. In one embodiment, the filter material is a polyurethane film having a thickness of les than 25 μm. The filter can be constructed from one or more sections of filter material. In the two-section embodiment, the outer edges of the first and second sections are overlapped and bonded using solvent, heat or other bonding process. In the single-section embodiment, the outer edges of the first section are overlapped and bonded using bonding agents, such as solvent or adhesive, heat or other bonding process. Filters of the present invention have a reduced amount of hysteresis so as to reform to its original shape when deployed.

摘要： A medical device for use in delivering RF energy to a tissue opening is disclosed. In one embodiment, the medical device comprises a compliant electrode. The compliant electrode can include a shape memory material, such as NITINOL, to facilitate the electrode having at least one relaxed orientation. The electrode can be deployed from a delivery shaft inside the left atrium, for example, of a heart through the delivery shaft. The electrode can be configured to substantially conform to the tissue proximate the tissue opening. After energy is applied to the tissue between the left and right electrodes, the left electrode can be removed from the left atrium by being received back into the delivery shaft and the delivery shaft thereafter removed from the opening.
