The packaging assembly having a locked configuration in which the ring and the valve support are locked together and the sutures tension the replacement heart valve. The packaging assembly is designed to hold and transport a replacement heart valve and fits within a shipment jar.

SYSTEMS AND METHODS FOR CRIMPING AND DEVICE PREPARATION

Apparatuses, systems, and methods for crimping prosthetic implants onto a delivery apparatus are disclosed. In some examples, a support body for a prosthetic heart valve can comprise a first portion comprising an alignment device configured to couple with a crimping device, and a second portion comprising a support surface that tapers from a wider end disposed adjacent the first portion to a narrower end, where the support surface is configured to receive the prosthetic heart valve thereon and hold one or more leaflets of the prosthetic heart valve in an open position. The support body can further comprise a central channel extending through the first portion and the second portion, the central channel configured to receive a delivery apparatus for the prosthetic heart valve therethrough.

ALIGNMENT TOOL FOR ALIGNING HEART VALVE WITH DELIVERY SYSTEM

An alignment tool for loading a stent includes a plurality of arms each having a shaft with an engagement region moveable between a first, angled configuration relative to the shaft, and a second, straight configuration, with each engagement region having an inner surface shaped to mate with a stent holder. The alignment tool further includes a lock ring having a lumen configured to receive the plurality of arms, with the lock ring configured to slide over the arms between a first retracted position in which the engagement region of each arm is exposed and allowed to bias into the angled configuration, and a second locked position in which the lock ring extends over at least a portion of the engagement regions and compresses the engagement regions into the straight configuration. The alignment tool may also include a spring configured to bias the lock ring in the locked position.

APPARATUS FOR COMPRESSING A REPLACEMENT HEART VALVE IMPLANT

An apparatus for compressing a replacement heart valve implant may include a tubular member having a wall having an outer surface and an inner surface defining a lumen of the tubular member, wherein the inner surface includes a tapered portion having a radially inward taper in a distal direction, and a plurality of flexible arms projecting radially inward from the tapered portion. The plurality of flexible arms may project radially inward from the inner surface at least 50% of a distance from the inner surface to a central longitudinal axis of the tubular member in an unbiased configuration. The plurality of flexible arms may be configured to push a plurality of leaflets of the replacement heart valve implant radially inward as the replacement heart valve implant passes through the tubular member.

Stented vascular graft

A vascular graft incorporating a stent into a portion of its length. While various materials may be used for the vascular graft, the graft is preferably an ePTFE graft. The stent is preferably a self-expanding stent, although it may alternatively be a balloon expandable stent. The vascular graft preferably has a continuous inner tubular liner that extends between the opposing ends of the graft and provides a continuous luminal surface for blood contact that is uninterrupted by seams or joints. The length portion of the graft that does not include the stent has a greater wall thickness than does the portion including the stent.

Transcatheter heart valve storage container and crimping mechanism

Disclosed herein is a storage container for an expandable prosthetic heart valve that crimps the valve upon opening the container and removal of the valve from the container. The container includes a housing sized to receive the heart valve in its expanded configuration and a crimping mechanism. The crimping mechanism is incorporated into the container and engages the heart valve so as to operably convert the heart valve from its expanded configuration to its smaller crimped configuration upon opening the container and removing the valve.

Systems and methods for treating cardiac dysfunction

A system for treating cardiac dysfunction can include an expandable device for insertion into a heart, a foot configured to contact a portion of the heart, a support frame, and a membrane coupled to the support frame. The support frame can include a plurality of radially expandable struts each having a first free end configured to extend beyond the foot and a second end coupled to the foot. The plurality of radially expandable struts can include a plurality of staggered stops, and each of the stops can be positioned on a respective one of the struts proximal to the first free end of the respective one of the struts. Method for treating cardiac dysfunction can include implanting the systems described herein into a chamber of the heart.

Folding patterns and loading funnel for improved transcatheter valve loading forces

A loading assembly for crimping and loading a prosthetic heart valve into a delivery device includes a loading base, a base funnel, and a compression member. The loading base has a support and a body extending from the support with a recess defined within the body. The recess is configured to receive a substantial portion of the annulus section of the heart valve in an at least partially collapsed condition. The base funnel is configured to be coupled to the loading base and to at least partially collapse the annulus section of the heart valve as it is inserted into the recess in the loading base. The compression member is configured to be coupled to the loading base with the heart valve inserted in the recess for further collapsing the heart valve and loading it into the delivery device.

MEDICAL DEVICE LOADING TOOL

Example medical device loading devices are disclosed. An example loading device for a stent-valve includes an elongated body having a proximal end region, a distal end region and a lumen extending therein. The loading device also includes a collar coupled to the distal end region of the body, the collar including first end region, a second end region and a lumen extending therein. Further, the loading device includes a first compression assembly coupled to the collar, wherein the first compression assembly is configured to shift between a first position a second position. The loading device also includes a second compression assembly coupled to the collar, wherein the second compression assembly is configured to shift between a third position and a fourth position.

Apparatus and methods for delivery, repositioning, and retrieval of transcatheter prosthetic valves

Apparatus and methods are described herein for use in the delivery and deployment of a prosthetic mitral valve into a heart. In some embodiments, an apparatus includes a catheter assembly, a valve holding tube and a handle assembly. The valve holding tube is releasably couplable to a proximal end portion of the catheter assembly and to a distal end portion of the handle assembly. The handle assembly includes a housing and a delivery rod. The delivery rod is configured to be actuated to move distally relative to the housing to move a prosthetic heart valve disposed within the valve holding tube out of the valve holding tube and distally within a lumen of the elongate sheath of the catheter assembly. The catheter assembly is configured to be actuated to move proximally relative to the housing such that the prosthetic valve is disposed outside of the lumen of the elongate sheath.
