摘要： A filter system, comprising an elongate filter body defining a lumen and having a proximal end and a distal end. A valve can be provided defining a lumen and having a reversibly sealable opening for unidirectional flow of a fluid through the lumen. The valve can be adjoined proximal the distal end of the elongate filter body, wherein the elongate filter body filters the unidirectional flow of the fluid passing through the lumen of the valve and the lumen of the elongate filter body.

摘要： An apparatus and method for closing an opening in a blood vessel wall is disclosed. The apparatus includes at least one member which is extended through a tissue tract formed through the epidermis and subcutaneous layer of skin and through the opening in the blood vessel. The member includes a proximal end and a distal end with the distal end being positionable proximate to the opening in the blood vessel wall. A positive electrode is positioned next to the distal end with a negative electrode being positioned next to the proximal end When the electrodes are energized an electric field is created therebetween, blood cells are attracted to the positive electrode, and a thrombus is formed at the opening in the blood vessel wall. The member may include a balloon at the distal end to temporarily occlude blood flow from the blood vessel to the tissue tract to facilitate formation of the thrombus. In addition, the shape of the balloon may be tailored to facilitate the formation of the thrombus including, but not limited to, the creation of pockets and self-supporting balloons

摘要： A thrombectomy system may include an elongate shaft that defines a high pressure lumen and a low pressure lumen. The high pressure lumen may terminate near an end of the low pressure lumen. An expandable capture basket may be disposed near the end of the low pressure lumen. A thrombectomy apparatus may include an elongate shaft, an evacuation lumen extending within the elongate shaft and a high pressure lumen extending within the elongate shaft. A capture apparatus may be disposed within a wire lumen that extends within the elongate shaft such that the capture apparatus extends distally from the wire lumen.

摘要： Some embodiments of pacing systems employ wireless electrode assemblies to provide pacing therapy. The wireless electrode assemblies may wirelessly receive energy via an inductive coupling so as to provide electrical stimulation to the surrounding heart tissue. In certain embodiments, the wireless electrode assembly may include one or more biased tines that shift from a first position to a second position to secure the wireless electrode assembly into the inner wall of the heart chamber.

摘要： Apparatus, systems, and methods for percutaneous valve replacement and/or augmentation are provided. The apparatus includes a valve having a valve frame, a valve leaflet coupled to the valve frame, and a leaflet transition member coupled to the valve leaflet. The valve leaflet and leaflet transition member can transition from a first position where the valve leaflet and leaflet frame are at least partially outside a lumen of the valve frame to a second position where the valve leaflet and the leaflet transition member are within the lumen of the valve frame.

摘要： Apparatuses, systems, and methods for use in a vascular system. The apparatus include a circulatory valve having a valve frame in which frame members define frame cells. Frame cells include joints in opposing relationship, where the joints transition from a first stable equilibrium state through an unstable equilibrium state to a second stable equilibrium state as the joints are drawn towards each other.
