Abstract: The present disclosure provides at least one hemostasis valve, an introducer, and a retrieval device. The hemostasis valve may include a sealing member, a pressing assembly and a rotary motion assembly. The sealing member may be configured to define a sealing cavity which is transversely contractible. The pressing assembly is disposed at an outer periphery of the sealing member. The pressing assembly is configured for linear motion in a transverse direction of the sealing cavity to change a dimension of the sealing cavity. The rotary motion assembly is coupled to the pressing assembly, and the rotary motion assembly may be configured to convert rotary motion into the linear motion of the pressing assembly through the coupling. The hemostasis valve of the present disclosure can perform active hemostasis sealing for one or more medical devices and is convenient to use.

Abstract: The present disclosure provides a driving handle, an apparatus and a method for recapturing an implant. The driving handle for recapturing an implant comprises: a first slider and a second slider, the first slider and the second slider being distributed in a longitudinal direction; a fixing barrel which defines a tube passage that receives the first slider and the second slider; a movable barrel which sleeves on the fixing barrel; wherein the movable barrel is configured to move spirally along the fixing barrel during at least a portion of a stroke to drive the first slider and the second slider to move synchronously and linearly along the tube passage. The present disclosure can alleviate the technical problem of difficult recapturing operation due to relatively high resistance when recapturing the implant.

Abstract: A system for internal iliac preservation includes a catheter having a distal catheter portion and a proximal catheter portion; a first guidewire having a proximal portion extending from the proximal catheter portion, a distal portion and a medial portion disposed between the proximal portion and the distal portion; a first outer sheath slidably disposed over distal catheter portion; and an integrated second delivery system disposed within the outer sheath at the distal catheter portion. The integrated second delivery system includes a second guidewire; an expandable stent-graft disposed over a lumen of the second guidewire, and a slidable connector slidably disposed over the medial portion of the first guidewire, where the second guidewire is slidably engaged with the slidable connection to permit movement of the integrated second delivery system along the first guidewire when the first outer sheath is retracted from distal catheter portion.

Abstract: A stent graft system includes a first layer of graft material, a second layer of graft material, one or more stent members, one or more reducing belts, and a release wire. The one or more stent members are located between the first layer of graft material and the second layer of graft material. The second layer of graft material is formed to have a corresponding channel over each of the one or more stent members. The one or more reducing belts each include a loop at both ends and each is located in a corresponding channel around a corresponding one of the stent members. The release wire passes through both loops of each of the one or more reducing belts when the one or more stent members are in a compressed state. Pulling the release wire allows for the stent graft system to radially expand.

Abstract: A stent graft system includes a first graft, a second graft, and a third graft. Each of the first graft, the second graft, and the third graft forms a single lumen. When deployed, the first graft, the second graft, and the third graft are coupled together within an aorta.

Abstract: A prosthetic venous valve includes an expanding anchoring frame, a valve seat at the middle portion of the anchoring frame, a ball disposed within the lumen of the anchoring frame and having an outer diameter, and least one ball retention tether coupled with the ball and the anchoring frame. The ball retention tether includes at least one elastic component or material. The anchoring frame has an upstream end, a downstream end, a middle portion and a lumen extending through the anchoring frame from the upstream end to the downstream end. The ball moves between an open position, in which the ball is located apart from the valve seat, and a closed position, in which the ball is located in contact with or near the valve seat to reduce or prevent backflow of blood through the prosthetic venous valve.
