Abstract: A medical device delivery system can include a dilator including a tip having a taper in a distal direction, a coupler, and a flap that radially protrudes from the tip. The flap can be configured to bend against a body lumen to cover at least a portion of the delivery system when the dilator is tracked through the body lumen. A medical device delivery system can include a dilator including a tip having a lumen and a coupler having a lumen. The coupler can be configured to securely connect to the tip such that the lumen of the tip is aligned with the lumen of the coupler to allow a guide wire to pass therethrough. Methods for loading a medical device into a delivery catheter are also disclosed.

Abstract: A visualization device for use with a loading tray includes a frame comprising a floor, a first side wall extending generally perpendicular from the floor, and a second side wall extending generally perpendicular from the floor and spaced from the first side wall. The visualization device further includes a mirror abutting the floor of the frame. A magnifying glass may also be supported by top edges of the first and second side walls, or by runners coupled to the top edges of the first and second side walls. The visualization device may be slideably disposed in a reservoir of a loading tray.

Abstract: A delivery system for delivering a medical device through a vasculature can include a capsule for housing the medical device during delivery and a marker band rotatably fixed to the capsule. The marker band can include a band portion and a single indicator protruding from the band portion. The indicator can allow the rotational orientation of the marker band to be determined while the medical device is in the vasculature, the rotational orientation being around a central axis of the vasculature. A delivery system for delivering a medical device through a vasculature includes a capsule for housing the medical device during delivery and a marker band attached to a proximal end of the capsule. The marker band can include a base portion and a protrusion that can be configured to extend from the base portion towards a distal end of the capsule. Related methods are also described.

Abstract: A medical device loading system can comprise a first housing, a second housing, and a plate. The first housing comprises a first open end, a first tapered inner surface, and a second open end. The second housing comprises a third open end, a second tapered inner surface, and a fourth open end. The second housing can define a slot between the second tapered surface and the third open end. The plate can be configured to be slidably received within the slot. The loading system can further comprise a first elongated member and a second elongated member.

Abstract: A delivery system for percutaneously delivering and deploying a stented prosthetic heart valve. The delivery device includes a delivery sheath slidably disposed over an inner shaft, and a capture assembly. The capture assembly includes at least one release feature for releasing the stented prosthetic heart valve from the delivery device.

Abstract: A crimping tool includes a housing portion defining a funnel segment and a suture locking mechanism positioned to lock sutures therein. One or more sutures can be coupled with a prosthesis and secured to the suture locking mechanism. The suture locking mechanism can be operated to draw the prosthesis through the funnel segment.

Abstract: A delivery device for percutaneously deploying a prosthetic valve includes a sheath, an inner shaft, and a release assembly. The release assembly is disposed between the sheath and the inner shaft, and includes a retraction member, a release member, and a retention member. The retraction member can self-retract in length from an extended condition to a retracted condition. The release member can self-expand from a compressed condition to an expanded condition. The retention member is distal the release member. In a delivery state, the sheath end is distal the retention member, the release member is in the compressed condition and the retraction member in the extended condition to retain the prosthesis. In a deployment state, the sheath end is positioned to permit the release member to self-transition to the expanded condition, allowing the retraction member to self-transition to the retracted condition and release the prosthesis.
