A system includes a medical device for implanting in a valve of a subject, the implantable medical device having a self-expanding frame; and a holder configured to retain the frame of the implantable medical device in a constricted configuration and to control expansion of the frame. The holder has a controllably constrictable and expandable loop, wherein the loop is disposed about at least a portion of the self-expanding frame such that constriction or expansion of the first loop controls constriction or expansion of the frame.

Valve delivery tool

An elastic percutaneous elastic introducer sheath is disclosed which can locally expand and reduce to accommodate a transcatheter medical device. The elastic introducer sheath includes a non-circumferentially continuous elastic frame, a liner, and a jacket.

Elastic introducer sheath

A heart valve therapy system including a delivery device and a stented valve. The delivery device includes an outer sheath, an inner shaft, an optional hub assembly, and a plurality of tethers. In a delivery state, a stent frame of the prosthesis is crimped over the inner shaft and maintained in a compressed condition by the outer sheath. The tethers are connected to the stent frame. In a partial deployment state, the outer sheath is at least partially withdrawn, allowing the stent frame to self-expand. Tension in the tethers prevents the stent frame from rapidly expanding and optionally allowing recapture. Upon completion of the stent frame expansion, the tethers are withdrawn.

Systems, devices and methods for transcatheter valve delivery

Embodiments hereof relate to a delivery system for a transcatheter valve prosthesis, the delivery system having an integral centering mechanism to circumferentially center both the delivery system and the valve prosthesis within a vessel at the target implantation site. The centering mechanism may include expandable wings that may be selectively aligned with openings formed through a sidewall of an outer shaft of the delivery system, a coiled wing that may be selectively exposed through an opening formed through a sidewall of an outer shaft of the delivery system, a plurality of elongated filaments extending through a plurality of lumens of an outermost shaft of the delivery system that may be selectively deployed or expanded, an outer shaft that includes at least one pre-formed deflection segment formed thereon, a tool having a deployable lever arm, and/or a plurality of loops deployable via simultaneous longitudinal and rotational movement.

Delivery system having an integral centering mechanism for positioning a valve prosthesis in situ

A profile altering tip is provided for a delivery system. The tip defines a first profile with a generally conical shape and a second profile with an expanded profile. During use of the delivery system, a tip profile control assembly can alter the tip from the first profile to the second profile.
