    摘要： Transcatheter prosthesis delivery catheter assemblies having a catheter and a lumen extending through the catheter. Such assemblies also have a elongate body having an outer surface and extending at least partially within the lumen. The elongate body has a stop. Delivery catheter assemblies also include a capsule interconnected to the catheter with the elongate body, the capsule including a reservoir. A fluid path extends from the lumen to the reservoir, within the capsule. A prosthesis is loaded within the capsule. Methods can include delivering the capsule though a patient's vasculature to a treatment site and directing fluid in a direction from the lumen, over the elongate body and into the reservoir to cause the capsule to advance with respect to the catheter, at least partially unsheathing the prosthesis, until the stop restricts further movement of the capsule and prevents further fluid from being transferred from the lumen to the reservoir.

    摘要： Delivery devices and methods for percutaneously delivering a prosthetic valve to the heart of a patient. These prosthetic valves may be configured to provide complimentary features that promote optimal placement of the prosthetic valve in a native heart valve, such as the aortic valve, mitral valve, pulmonic valve, and/or tricuspid valve. The delivery device includes a release sheath (154) assembly housed within an outer delivery sheath (52). A release sheath component of the assembly captures a portion of the prosthetic valve (32) to the delivery device, and effectuates complete release of the prosthetic valve with retraction of- the outer sheath.
