    Abstract: Disclosed herein are representative embodiments of methods, apparatus, and systems used to deliver a prosthetic heart valve to a deficient valve. In one embodiment, for instance, a support structure and an expandable prosthetic valve are advanced through the aortic arch of a patient using a delivery system. The support structure is delivered to a position on or adjacent to the surface of the outflow side of the aortic valve (the support structure defining a support-structure interior). The expandable prosthetic valve is delivered into the aortic valve and into the support-structure interior. The expandable prosthetic heart valve is expanded while the expandable prosthetic heart valve is in the support-structure interior and while the support structure is at the position on or adjacent to the surface of the outflow side of the aortic valve, thereby causing one or more native leaflets of the aortic valve to be frictionally secured between the support structure and the expanded prosthetic heart valve.

    Abstract: Aspects of an expandable sheath can be used in conjunction with a catheter assembly to introduce a prosthetic device, such as a heart valve, into a patient. Such aspects can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some aspects can include a sheath comprising an inner layer comprising a reinforcing layer rolled into a spiral slidable configuration and encapsulated within a polymer layer comprising a tether portion and an outer layer disposed over the inner layer. The disclosed sheath is configured to locally expand from a predetermined first diameter d1 to an expanded second diameter d2 during application of a radial outward force by passage of the medical device through the sheath.

    Abstract: A delivery system includes an elongate shaft, a handle, a first clasp control member, and a second clasp control member. The handle is connected to a proximal portion of the elongate shaft. The first and second clasp control members each extend into a distal portion of the elongate shaft, through at least a portion of the elongate shaft, out of the proximal portion of the elongate shaft, and through the handle. The first and second clasp control members have paths that include a first parallel portion in the elongate shaft where the first clasp control member and the second clasp control member are parallel, and a diverging portion that is proximal to the first parallel portion where the first clasp control member diverges from the second clasp control member.

    Abstract: A delivery system includes an elongate shaft, a handle, a first clasp control member, a second clasp control member, and an actuator. The handle is connected to a proximal portion of the elongate shaft. The first and second clasp control members each extend into a distal portion of the elongate shaft, through at least a portion of the elongate shaft, out of the proximal portion of the elongate shaft, and through the handle. The actuator is coupled to the handle and has a first side portion connected to the first clasp control and a second side portion connected to the second clasp control. The first side portion and the second side portion are releasably couplable such that when the first side portion and the second side portion are coupled, proximal movement of the actuator proximally pulls both the first clasp control member and the second clasp control member, and such that when the first side portion and the second side portion are uncoupled, individual proximal movements of the first side portion and the second side portion independently pull the first clasp control member and the second clasp control member, respectively.
