Abstract: 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components that limit trauma to the expanded prosthetic valve and body channels as the distal tip of the catheter is withdrawn through the expanded valve and thereafter from the body.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.

Abstract: A system includes a delivery catheter and a separately-packaged implantable medical device assembly. The assembly includes a relatively compact implantable medical device, a support shaft, a tether, and a snare mandrel. The tether, which extends in the support shaft, has a distal portion coupled to the device, at a distal end of the support shaft, and a proximal portion protruding from a proximal end of the support shaft, for engagement by a hook of the snare mandrel. An operator may use the engaged snare mandrel to pull the support shaft into a lumen of an inner shaft of the catheter so that the coupled device comes into engagement with a flared end of the catheter inner shaft. Then, after locking the proximal portion of the tether within the catheter, the operator may advance a receptacle of the catheter over the 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 system for an implantable medical device includes a tool and a tethering member extending side-by-side within an inner shaft thereof; the tool extends within a first lumen, being in sliding engagement therein, and includes a distal end coupling feature that protrudes from a distal end of the inner shaft; and the tethering member has a first segment extending within a second lumen, and a second segment extending from the first segment and distally from the distal end of the inner shaft to an end of the tethering member, which is configured to engage with a holding member of the device, and with which the coupling feature of the tool is configured to couple. A retainer may be joined to another end of the tethering member that protrudes from a proximal port of the system.
