Embodiment Construction

[0066] Specific embodiments of the present application are now described with reference to the drawings, wherein like reference numerals indicate identical or functionally similar elements. The terms "distal" and "proximal" are used in the description below with respect to position or orientation relative to the treating clinician. "Distal" or "distally" is a location away from the clinician or a direction away from the clinician. "Proximal" and "proximally" are a position nearer to a clinician or a direction towards a clinician. Although the present disclosure has been described with reference to preferred embodiments, workers skilled in the art will recognize that various changes in form and details could be made without departing from the spirit and scope of the disclosure.

[0067] As described below, some aspects of the present disclosure relate to transcatheter valve delivery devices that use one or more flexible strands (e.g., sutures, threads, filaments, etc.) to comp...

Abstract

Delivery devices for a stented prosthetic heart valve. The delivery device includes a spindle, at least one cord, and a lateral control feature. The cord is tensioned to crimp the prosthesis to a compressed condition for delivery to a target site. Tension is lessened to allow the prosthesis to self-expand. In a tethered and expanded state in which the prosthesis has self-expanded and is connectedto the spindle by the cord, the lateral control feature directs the spindle to a prescribed location relative to the prosthesis appropriate for a functional evaluation of the prosthesis. In some embodiments, the spindle is directed to a center of the prosthesis; in other embodiments, the spindle is held at a commissure of the prosthesis. The lateral control features of the present disclosure assume numerous forms.
