Patent number: 12121436Abstract: A prosthetic heart valve is disclosed that is deformable between collapsed, radially uncompressed, and target conditions. The prosthetic heart valve includes an inner frame, at least one leaflet, and a braided wire mesh arranged outside and coupled to the inner frame by a coupling portion. The braided wire mesh includes a body portion between the coupling portion and a flared portion. In the radially uncompressed condition, the prosthetic heart valve forms a cavity surrounded by the braided wire mesh and the inner frame. In the target condition, only a part of the length of the body portion is radially compressed along an axis extending from an upstream side to a downstream side. In the collapsed condition, the inner frame and braided wire mesh are radially collapsed over their entire length. In the radially uncompressed condition, the body portion is tubular and the braided wire mesh has a rotationally symmetric circumference.Type: GrantFiled: November 8, 2019Date of Patent: October 22, 2024Assignee: MEDTRONIC BAKKEN RESEARCH CENTER B.V.Inventors: Luc Alleleyn, Maurice Verbeek, Joost Ubachs, Victor Duijsens, Estelle Fraysse

Patent number: 12115066Abstract: This disclosure is directed to prosthetic heart valves having elongated sealing members. As one example, a prosthetic heart valve comprises an annular frame, a leaflet assembly comprising a plurality of leaflets, and a skirt assembly comprising an inner skirt, an outer skirt, and/or a third skirt. The frame is radially compressible and expandable between a radially compressed state and a radially expanded state and comprises a plurality of apices at an inflow end. The skirt assembly forms a pocket at the inflow end of the frame that creates extra space between the inflow end of the frame and the skirt assembly when the frame is in the radially expanded state. This pocket allows the apices at the inflow end of the frame to move towards an inflow end of the pocket when the frame is radially compressed to the radially compressed state without protruding through the skirt assembly.Type: GrantFiled: September 20, 2023Date of Patent: October 15, 2024Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Izaak Rosen, Bich Hoang Pham, Timothy C.

Patent number: 12109112Abstract: A heart valve therapy system including a delivery device and a stented valve. The delivery device includes an outer sheath, an inner shaft, an optional hub assembly, and a plurality of tethers. In a delivery state, a stent frame of the prosthesis is crimped over the inner shaft and maintained in a compressed condition by the outer sheath. The tethers are connected to the stent frame.

Patent number: 12102328Abstract: A left atrial appendage (LAA) occluder and an LAA occlusion system are disclosed. The LAA occluder enables an increased surgical success rate by allowing repeated good positioning, retrieval and release of the occluder and avoiding the problem of entanglement of the occluding stent during surgery. The LAA occluder includes an occluding stent, a proximal securing member a distal securing member. The occluding stent includes an occlusion structure and a traction structure. The delivery device includes a hollow push tube and a control shaft. The distal securing member can be driven by the control shaft to move toward the proximal securing member until a first distal end of the occlusion structure is in a collapsed configuration, where the distal securing member is blocked from further movement, avoiding the problem of entanglement arising from inward rolling of the occluding stent in the vent of human error.Type: GrantFiled: September 11, 2019Date of Patent: October 1, 2024Assignee: SHANGHAI MICROPORT CARDIOADVENT CO., LTD.Inventors: Yi Zhou, Haiyong Huang, Shaoyang Liu, Yao Yao, Junfei Li
