  • Pressure sensing guidewire systems including an optical connector cable
    Patent number: 11058307
    Abstract: Medical devices including optical connector cable assemblies are disclosed. An optical connector cable assembly may include an optical connector cable having a first optical fiber extending therefrom. The optical connector cable may include a distal connector configured to connect to a guidewire. The distal connector may include an inner housing and a guidewire locking mechanism. The distal connector may also include an actuator. Actuation of the actuator may move the inner housing from a first position to a second position. When the inner housing is in the first position the guidewire locking mechanism is configured to secure the guidewire and the guidewire is rotatable with respect to the optical connector cable. When the inner housing is in the second position the guidewire locking mechanism is in an open state for receiving or removing the guidewire.

  • Systems and methods for loading a valve prosthesis onto a catheter
    Patent number: 9414917
    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.

  • Prosthetic valve crimping
    Patent number: 9199348
    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.
