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 method carried out by a system configured to analyze platelet aggregation includes retaining a ferromagnetic object at an elevation of a chamber in which a sample of blood or plasma is disposed. The ferromagnetic object is retained at the elevation for a period of time. The ferromagnetic object is then released from the elevation. The ferromagnetic object minimal position is measured following the release of the ferromagnetic object. The object minimal position may be correlated with amount of platelet aggregation in the sample.

摘要： Devices, assemblies, systems, and techniques described herein may deliver a pressure wave to structures of a heart, such an aortic valve. For example, a medical assembly may include an expandable member configured to expand from a collapsed configuration to an expanded configuration, the expandable member configured to at least partially define a channel through the expandable member in the expanded configuration and one or more electrodes carried by the expandable member. The one or more electrodes may be configured to transmit an electrical signal through a fluid to cause the fluid to undergo cavitation that generates a pressure wave within the fluid.

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： A prolapse prevention device formed by a continuous wire-like structure having a first end and a second end disconnected from each other. The continuous wire-like structure is substantially straight in a delivery configuration. The prolapse prevention device in a deployed configuration includes a centering ring of the continuous wire-like structure configured to seat adjacent to and upstream of an annulus of a heart valve in situ, a vertical support of the continuous wire-like structure which extends from the centering ring and includes an apex configured to seat against a roof of an atrium in situ, and a leaflet backstop of the continuous wire-like structure extending radially inward from the centering ring and configured to contact at least at least a first leaflet of the heart valve in situ to exert a pressure in a downstream direction on the first leaflet to prevent the first leaflet from prolapsing into the atrium.

摘要： A proximal stent-graft retention system includes a stent-graft having a suture loop attached to a proximal end of the stent-graft and a delivery catheter having a distal tip that includes a retention feature. The retention feature can include a slot extending through a sidewall of the distal tip and a trigger wire. The slot of the distal tip exposes a portion of the trigger wire within the tip lumen such that the trigger wire may extend through the suture loop of the stent-graft at the slot of the distal tip of the delivery catheter and is configured to retain the proximal end of the stent-graft in the radially expanded configuration via the suture loop to prevent distal migration and compression of the stent-graft. Proximal retraction of the trigger wire releases the suture loop of the stent-graft such that the stent-graft is no longer coupled to the delivery catheter.

摘要： An assembly includes a medical device having a stent and a prosthetic valve connected to the stent. The prosthetic valve includes valve leaflets. The assembly further includes a buffer piece having a leaflet cover and a removable attaching structure. The leaflet cover protects the valve leaflets and the removable attaching structure removably attaches the buffer piece to the medical device. The buffer piece prevents contact, imprinting, abrasion, and/or damage to the valve leaflets.

摘要： Distal tips for use with delivery catheters are disclosed that are configured to facilitate deflection of the catheters as they are advanced through the vasculature to a desired treatment site. Distal tips so configured realize one or more of the objectives of safer, more accurate steering of the catheter through the vasculature.

摘要： The techniques of this disclosure generally relate to a valve prosthesis having a prosthetic valve, a stent structure, and anti-migration spikes. The stent structure is coupled to the prosthetic valve and includes an inflow portion. The anti-migration spikes are attached to the inflow portion, the anti-migration spikes protruding radially outward and in an outflow direction from the inflow portion. The anti-migration spikes penetrate into tissue of the vessel, e.g., the aortic annulus of a patient's left ventricle, to prevent migration, i.e., undesirable movement, of the valve prosthesis within the vessel after deployment.

摘要： An in-situ fenestration device. The device includes a sheath including a proximal end and a distal end. The device also includes an expandable cone including a proximal end, a distal end, and a body extending between the proximal end and the distal end. The expandable cone includes a heating element. The expandable cone is configured to expand from a crimped state within the sheath into an expanded state extending from the distal end of the sheath. The heating element of the expandable cone is configured to be energized with an energy source to form a fenestration in a graft material at a fenestration site of a stent graft.
