摘要： The disclosure relates to transcatheter stented prosthesis delivery devices including a handle assembly connected to a shaft assembly on which a stented prosthesis is loaded and compressively retained with a plurality of elongate tension members. The delivery devices include a cutting assembly that can sever the elongate tension members after the stented prosthesis is expanded at a target site so that the delivery device can be withdrawn from the patient. Certain embodiments position the cutting assembly at least within the shaft assembly and others position the cutting assembly over the shaft assembly. Various disclosed cutting assemblies are actuated with the handle assembly or the like, which draw the tension members across the blade or vice versa.

摘要： Delivery devices for delivery of a stented prosthetic heart valve. Various delivery devices include an outer sheath assembly including an outer sheath connected to a capsule that is advanced proximally to retain the prosthetic valve, which is secured over an inner shaft assembly of the delivery device. The delivery device further includes a bumper to provide a smooth transition of the capsule over the prosthetic valve during loading and recapture procedures. The bumper is expandable from a first position to a second position in which a distal end of the bumper is expanded to increase its diameter. The bumper can be biased in the second, expanded position so that the bumper automatically transitions to the expanded position upon retraction of the outer sheath.

摘要： A stent graft delivery system includes a stent graft and a thermal stent graft cutter for shortening the stent graft to a desired length in vivo. The thermal stent graft cutter is coupled to at least one of a stent graft cover at a distal longitudinal end of a cover body thereof, and the inner lumen tip of an inner lumen. A safety system allows activation of the stent graft cutter only when the stent graft is suitably sandwiched between the inner lumen tip and the distal end of the stent graft cover to inhibit inadvertent activation of the cutter and provide for proper cutting of the stent graft.

摘要： A medical system includes a catheter navigable through vasculature of patient to introduce a valve clip configured to join the edges of heart valve leaflets. The valve clip includes a deformable wire configured to engage valve leaflets, the wire extending from a first wire portion to a second wire portion. The catheter includes a handle having control members, an elongate body defining a lumen extending from the handle to a distal opening, and first and second delivery devices operatively coupled to a control member and extending through the lumen to the distal opening. Each delivery device is configured to releasably couple to a portion of the wire and moveable relative to the distal opening. The delivery devices are controllable at the handle to move the valve clip between an extended configuration and a contracted configuration to engage the valve leaflets.

摘要： A stent graft delivery system including a stent graft cover, a screw gear, and a handle assembly. The handle assembly includes an external slider, a T-tube, and a Y-adapter. The external slider is configured to rotate about the screw gear. The T-tube and the Y-adapter collectively form a hub configured to slide linearly along the screw gear as the external slider rotates. The T-tube defines a main lumen port extending therethrough and is configured to receive the stent graft cover and a main lumen. The Y-adapter defines a secondary lumen port and is configured to receive a secondary lumen.

摘要： Devices for, and methods of, compressing a stented prosthetic heart valve are disclosed. The method including inserting a stented prosthetic heart valve having a self-expandable stent frame into a container, initiating a cooling element in the container, transferring heat through a thermal conductor to cool an interior of the container, reducing a temperature of the self-expandable stent frame while located within the container to a critical temperature of not greater than 8° C., and compressing an outer diameter of the stented prosthetic heart valve while the stented prosthetic heart valve is at the critical temperature.

摘要： The techniques of this disclosure generally relate to an iliac branch device having an external iliac body, a common iliac branch, and an internal iliac branch. A diameter of the proximal opening of the common iliac branch is greater than a diameter of a distal opening of the external iliac body. The iliac branch device is configured to be deployed without going up and over the aortic bifurcation and without using some form of supra-aortic antegrade access such as through brachial or axillary artery access. This simplifies the procedure and reduces procedure time thus maximizing the success rate of the procedure and allows the procedure to be performed on a broad patient population.

摘要： A “dry” packaging in which a prosthetic heart valve is packaged within a container with hydrogel that can be provided in many forms. Certain embodiments include hydrogel that is preloaded with glycerol or the like. The hydrogel regulates the humidity within the container through a diffusion-driven mechanism if a gradient of humidity between the inside and the outside of the hydrogel exists. Humidity regulation is important to prevent the tissue of the valve structure from drying out. When the partially-hydrated hydrogel is present within container, which is saturated with air of a predefined humidity, the water molecules from the air will be absorbed by the hydrogel if the air humidity is high (i.e. when the thermodynamics favor hydrogel hydration) or vice versa. Various embodiments are configured to also house at least a portion of a delivery device for delivering the prosthetic heart valve.

摘要： An example medical device includes a balloon that is inflatable to an inflated configuration. The balloon includes a non-compliant layer coextruded on an inner layer, and an outer layer coextruded on the non-compliant layer. The non-compliant layer is configured to delaminate from the inner and the outer layers in the inflated configuration. The non-compliant layer may be configured to rupture in the inflated configuration. An example technique includes inflating the balloon to a predetermined pressure sufficient to rupture the non-compliant layer and insufficient to rupture both the inner and outer layers. The example technique further includes deflating the balloon, and introducing the balloon into a vasculature. Another example technique includes coextruding a non-compliant layer on an inner layer, coextruding an outer layer on the non-compliant layer, and forming a balloon from the inner layer, the non-compliant layer, and the outer layer.

摘要： A catheter includes a proximal shaft, a distal shaft, a pressure sensor, and at least one pressure sensor wire. The proximal shaft is substantially C-shaped such that in cross-section, the proximal shaft includes a first circumferential end, a second circumferential end, and a gap between the first circumferential and circumferential end. The proximal shaft defines a groove configured to receive a guidewire therein. The distal shaft is coupled to the proximal shaft and defines a guidewire lumen therein. The pressure sensor is coupled to the distal shaft. The pressure sensor wire is operably connected to the pressure sensor. A proximal portion of the pressure sensor wire is disposed within a proximal shaft wall of the proximal shaft and a distal portion of the pressure sensor wire is disposed within a distal shaft wall of the distal shaft.
