Abstract: A self-expanding filter for collecting emboli or thrombi in a vessel of a patient is disclosed. The filter has a tubular filter body that coils or spirals around an outer surface of an adjacently located, independent treatment device in a corkscrew fashion when deployed from a sheath delivery catheter. When fully deployed, an outer surface of the coiled tubular body conforms to the inner wall of the vessel and an inner surface of the coiled tubular body conforms to an outer surface of the treatment device. The treatment device is disposed within a longitudinal opening extending through the expanded, coiled tubular body of the filter during an interventional procedure.

Abstract: A radially deployable covered stent that predictably and dependably expands to an increased diameter state at relatively low deployment pressures while concomitantly minimizing the risk of tearing of the stent covering during expansion. The stent covering includes an inner cover and an outer cover that are bonded together through and around the stent structure to cover the stent. The stent cover is constructed from expanded polytetrafluoroethylene (ePTFE) having a structure of nodes interconnected by fibrils. The stent covering has a radial thickness of at least about 0.008? and an average internodal distance (IND) of at least about 100 microns when the stent is in the reduced diameter, unexpanded state. The covered stent deploys at an average deployment pressure of less than or equal to about 10 atm.

The stent covering includes an inner cover and an outer cover that are bonded together through and around the stent structure to cover the stent. The stent cover is constructed from expanded polytetrafluoroethylene (ePTFE) having a structure of nodes interconnected by fibrils. The stent covering has a radial thickness of at least about 0.008″ and an average internodal distance (IND) of at least about 100 microns when the stent is in the reduced diameter, unexpanded state. The covered stent deploys at an average deployment pressure of less than or equal to about 10 atm.

Abstract: A prosthesis is provided that is advantageously used to fill a soft tissue or muscle defect, such as an inquinal or femoral hernia. In a first aspect of the invention, multiple layers of a flexible, mesh material are attach together at a finite number of joins. A tab is placed at the geometric center of one of the mesh layers to facilitate insertion of the mesh into the defect. The tab also creates a blunt tip that reduces irritation and discomfort to the patient. In a second aspect of the invention, a prosthesis is provided that includes a barrier layer between two or more layers of flexible, mesh material to prevent adhesion of the device to the tissue. All layers are attached together by a finite number of joins. A tab is placed at the geometric center of one of the mesh layers to facilitate insertion of the mesh into the defect.
