The techniques of this disclosure generally relate to a modular assembly including first and second stent-grafts. The first stent-graft includes a body portion having a first diameter and a waist portion having a second diameter less than the first diameter. The waist portion is at a distal end of the first stent-graft. The second stent-graft includes a captured proximal portion configured to be located within the first stent-graft. The captured proximal portion includes a seated portion configured to be located proximal to the waist portion. The seated portion has a third diameter greater than the second diameter to form a mechanical interlock between the first stent-graft and the second stent-graft.

A stent-graft prosthesis for implantation within a body vessel includes a graft material, a frame, and a channel. The graft material includes a proximal end, a distal end, and a graft lumen extending between the proximal and distal ends. The frame is coupled to the graft material. The channel is configured to relieve pressure associated with pulsatile blood flow during implantation of the stent-graft prosthesis within a body vessel. The channel permits blood to flow from an upstream side of the stent-graft prosthesis to a downstream side of the stent-graft prosthesis when the stent-graft prosthesis is in a partially expanded configuration in the body vessel. The channel may be a plurality of channels.

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.

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.

Systems and methods for delivering and implanting heart valves are disclosed. The delivery systems can include an integrated introducer. The integrated introducer can include a sheath having an inner diameter that is smaller than the outer diameter of a delivery capsule of the delivery system and an outer diameter that is approximately equal to the outer diameter of the delivery capsule. The integrated introducer can include a hub having a hemostatic seal. The hub can have a locking mechanism configured to fix the integrated introducer in place on the delivery system.

A delivery system for percutaneously deploying a prosthetic heart valve. The system includes an inner shaft assembly, a delivery sheath capsule and a handle maintaining a first actuator and a second actuator. The capsule is configured to compressively retain the prosthetic heart valve over the inner shaft assembly. The first actuator is operated to proximally retract the delivery sheath capsule and expose the prosthetic heart valve relative to the capsule. The second actuator is operated to proximally retract the prosthetic heart valve by transmitting forces to the inner shaft assembly.

A stent graft assembly with a sacrificial entry/exit port is disclosed. A first sacrificial port extends from a first branch stent graft and is configured to face a second branch stent graft when the stent graft assembly is in an expanded configuration. Likewise, a second sacrificial port can be provided, and can extend from the second branch stent graft and configured to face the first branch stent graft when the stent graft assembly is in the expanded configuration. The first and optional second sacrificial ports are configured to transition between (i) an open configuration to enable a guidewire or other surgical tool to pass from the first branch stent graft to the second branch stent graft while bypassing the main body, and (ii) a closed configuration to inhibit blood flow therethrough.

An iliac branch device has 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.

A medical device includes an inflatable balloon defining an interior surface and an exterior surface, and a coating including a therapeutic agent disposed on the exterior surface of the inflatable balloon. The coating has a release transition temperature within a range from about 25&#xb0; C. to about 50&#xb0; C. When the temperature of the coating is below the release transition temperature, the coating retains at least a portion of the therapeutic agent on the exterior of the inflatable balloon. When the temperature of the coating is above the release transition temperature, the coating releases at least a portion of the therapeutic agent from the exterior of the inflatable balloon.

Distal tips for use with delivery catheters are disclosed that are configured to maintain complete engagement between the distal tip and a distal opening of a sheath component of the delivery catheter so as to prevent separation therebetween and/or to prevent fish-mouthing of a distal leading edge of the sheath component during in vivo use. Distal tips so configured realize one or more of the objectives of safer tracking of the delivery catheter through the vasculature, safe crossing of the delivery catheter through structural components of the vasculature and heart, such as through native valves, and safe removal of the delivery catheter post deployment.
