A crimping device for reducing the size of prosthetic heart valve devices and other medical devices. A hydraulically operated piston advances a pusher toward an opening of a funnel. An interior surface of the funnel is configured to provide substantially uniform compression forces to a prosthetic heart valve device between the pusher and the funnel as the pusher advances the prosthetic heart valve device into the funnel. A system may comprise the crimping device and a prosthetic heart valve device positioned between the pusher and the funnel. A technique for using the crimping device includes delivering a pressurized fluid and crimping a prosthetic heart valve device using the interior surface of the funnel.

Hydraulic crimping device

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 In a partial deployment state, the outer sheath is at least partially withdrawn, allowing the stent frame to self-expand.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 Upon completion of the stent frame expansion, the tethers are withdrawn.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

In some embodiments, a medical device delivery system includes a catheter and a retainer. The retainer can be engaged with the medical device to restrain relative movement of the medical device in one or more axial and/or radial directions. A variety of retainers and retainer systems are disclosed, many of which can reliably disengage the medical device from the retainer. Methods for using the medical device delivery system are also described.

Medical device delivery system and methods of delivering medical devices

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.

Medical device delivery system and methods of delivering a medical device

Trays and packaging systems for a prosthesis delivery device that permit conversion from a packaged, storage/or shipping configuration to a loading configuration for the loading of a prosthesis. The prosthesis may be a prosthetic heart valve. In the packaged configuration, the delivery device can be supported within the tray, which includes a recess and at least one clip maintaining the delivery device within the recess. In the loading configuration, the delivery device can be arranged for loading of the prosthesis within a bath area of the tray. Optionally, the delivery device can be stored in the packaged configuration in a U-shape. Some embodiments include an additional recess for positioning an indeflator fluid line or tubing. Methods of use are also disclosed.

Prosthetic delivery device trays, packaging systems and methods

Valve delivery catheter assemblies including components that limit trauma to the expanded prosthetic valve and body channels as the distal tip of the catheter is withdrawn through the expanded valve and thereafter from the body. Catheter assemblies according to the present invention can include a handle assembly, an introducer sheath, and a distal tip assembly. The handle assembly can include a fixed main handle and two or more rotating handles that allow a user to control the distal tip assembly of the catheter. A safety button can be included on the handle assembly to allow for precise and consistent positioning of the prosthetic valve in the body. A valve retaining mechanism can be included to assist in retaining the prosthetic valve prior to deployment.

Heart valve delivery catheter with safety button

A catheter assembly according to the present invention includes a handle assembly, an introducer sheath, and a distal tip assembly. The distal tip assembly can include first and second retaining sleeves and a slotted tip with a non-traumatic tip guard positioned at the proximal end of the slotted tip. The handle assembly can include a fixed main handle and two or more rotating handles that allow a user to control the distal tip assembly of the catheter. Each control knob on the handle assembly controls a portion of the components on the distal tip of the catheter by allowing for precise manipulation of various delivery shafts. Each delivery shaft extends from the handle assembly to respective positions towards the distal end of the catheter.

Distal tip assembly for a heart valve delivery catheter

Heart valve delivery systems and methods of delivering and implanting heart valves using delivery catheters are disclosed. The delivery systems can include a handle assembly which can include a first control mechanism, a second control mechanism, and a decoupling mechanism. The delivery systems can also include a delivery catheter extending from the handle assembly. The delivery catheter can include an outer shaft, which can be controlled by the first control mechanism; a prosthesis containing capsule comprising a proximal capsule portion connected to the outer shaft, and a distal capsule portion releasably coupled to the proximal capsule portion. After deploying a valve prosthesis, the capsule can be closed by activating the decoupling mechanism in the handle to rapidly close the distal and proximal capsule portions together. The delivery system can also include a centering element to guide the distal and proximal capsule portions together.

Trans-aortic delivery system with containment capsule centering device

A guidewire is coupled to a control module and extends through a lumen of the control module. The control module operates to transition between a first control state wherein the control module allows movement of the guidewire relative to a catheter and a second control state wherein relative axial movement between the catheter and guidewire is prevented.
