摘要： An aortic adapter assembly is provided, including a T-shaped flow connector, including: an inserted conduit portion, having a blood-contacting surface which is smooth; an extruded neck portion, wherein the inserted conduit portion is joined with the extruded neck portion; and a truss, disposed in the inserted conduit portion; wherein the T-shaped flow connector has a polymeric elastomer reinforced by the truss having a Nitinol material; wherein the inserted conduit portion has an inner wall which is gradually thinning at two conduit ends of the inserted conduit portion, with a proper distance of a tip of the conduit end to the outmost boundary of the truss, and the conduit end possesses a compliance-matching effect to an implant site artery; wherein a proximal end of the extruded neck portion is configured to be joined with an inlet adapter of a blood pump. The aortic adapter assembly is accompanied with a quick-connector type coupler and a deployment method to accomplish an insertion type flow communication between a ventricular assist device and the human circulation.

摘要： The invention relates to a catheter assembly for the intermittent occlusion of the coronary sinus (CS, 60). The catheter assembly comprises a shaft (17, 126). The shaft (17, 126) has a plurality of lumens (7A, 7B, 35, 38, 40, 40A, 40B), a distal end (22) with a distal tip (20A, 20B, 20C), an occlusion device (24, 56, 142) fixed to the distal tip (20A, 20B, 20C) and operable through at least one of the plurality of lumens (7A, 7B, 35, 38, 40, 40A, 40B) and a proximal handle (10). The catheter assembly further having at least one of the following:

the occlusion device (24, 142) having a diameter of 5 - 20 mm and adapted to occlude the coronary sinus ostium,
means of measuring the pressure at the distal tip (20 a, 20B, 20C) of the catheter assembly and distally to the occlusion device (24, 142), preferably using an optical pressure sensor (28),
an anchoring device (30, 54, 65, 80, 90A, 122) for anchoring the occlusion device (24, 142) in a predefined position in the coronary sinus (CS, 60), preferably in the ostium,
the distal end (22) being deflectable/steerable with deflection being controlled by an actuator arranged at the proximal handle (10).
