A removable percutaneous vascular filter system for blocking emboli in a vessel while allowing continued perfusion of blood comprises a guidewire (160) having distal (162) and proximal (174) ends and a filter (170). The filter comprises (a) a non-metallic, porous, filter membrane having a distal (17 ...
Apparatus for permanent placement across an ostium of a left atrial appendage in a patient, which includes a filtering membrane configured to extend across the ostium of the left atrial appendage. The filtering membrane has a permeable structure which allows blood to flow through but substantially i ...
An integrated optical biopsy forceps device and a method for tissue identification by optical analysis and biopsy sampling at a site within the body. The device includes an elongated catheter body for introduction into the body and navigation to an area of interest. An optical fiber extends through ...
Implant devices for filtering blood flowing through atrial appendage ostiums have elastic cover and anchoring substructures. The substructures may include reversibly folding tines or compressible wire braid structures. The devices are folded to fit in catheter tubes for delivery to the atrial append ...
A membrane applied to the ostium of an atrial appendage is disclosed. The membrane prevents blood clots in the atrial appendage from escaping therefrom and entering the blood stream which can result in a blocked blood vessel, leading to strokes and heart attacks. The membrane may be permeable or imp ...

The filtering membrane has a permeable structure which allows blood to flow through but substantially i ...
A cardiopulmonary bypass filter system comprises a housing (366) having distal and proximal ends, the proximal end comprising a connector (372) adapted to connect to at least one hose (360) and the distal end comprising a distal member (370) having first and second openings. The housing has a first ...
A removable vascular filter system for blocking micro-emboli, and macro-emboli while allowing the continued perfusion of blood, comprises a filter membrane (20) positioned on a guide wire (10), wherein a free end of the membrane sits tightly against the guide wire when the filter membrane (20) is in ...
A removable vascular filter system for capture and retrieval of emboli while allowing continuous perfusion of blood during a cardiopulmonary bypass procedure, comprising a porous filter membrane with variable diameter holes, and a filter membrane support structure. The system may minimize the incide ...
PROBLEM TO BE SOLVED: To provide a blood vessel filter system which permits an uninterrupted perfuse of blood and can trap, collect, and pull out an embolus.SOLUTION: The vessel filter system has a porous filter membrane (170) and a filter membrane support structure (169). This system is useful for ...
