  • Publication number: 20230088094
    Abstract: A modular handle assembly comprises a stationary main handle having proximal and distal ends. A first handle extends proximally from the main handle and is rotationally moveable relative to the main handle, the first handle having proximal and distal ends, wherein a rotational interface is located at the distal end. A second handle extends distally from the main handle and is rotationally moveable relative to the main handle, the second handle having proximal and distal ends, wherein a rotational interface is located at the proximal end. The proximal end of the main handle comprises a first rotational interface that is configured to engage with a rotational interface at the distal end of the first handle and wherein the distal end of the main handle comprises a second rotational interface that is configured to engage with the rotational interface at the proximal end of the second handle.

  • Patent number: 11484423
    Abstract: Methods and apparatuses to place a prosthesis within a receiving structure are provided. A delivery apparatus includes an elongated support member including a support member distal end. A stop cap is disposed at the support member distal end and includes a stop cap transverse dimension larger than an inner diameter of a receiving lumen of the receiving structure. An elongated prosthesis-positioning member extends along the support member and stop cap so a distal surface of the prosthesis-positioning member is disposed at a position longitudinally coincident with a portion of the stop cap. A sheath comprises a sheath lumen receiving the prosthesis-positioning member so the sheath translates longitudinally relative to the prosthesis-positioning member. The delivery apparatus has a loaded configuration in which the prosthesis is received in the sheath lumen with a proximal end of the prosthesis abutting the prosthesis-positioning member distal surface.

  • Patent number: 11376144
    Abstract: Systems and methods to place a prosthesis to have a preselected overlap with a receiving structure are provided. In one embodiment, a delivery system may include a primary sheath comprising a primary sheath lumen. The delivery system may further include a secondary sheath comprising a secondary sheath lumen. The primary sheath may be at least partially received within the secondary sheath lumen such that the primary sheath may translate longitudinally within the secondary sheath lumen. The delivery system may further include a prosthesis having proximal and distal ends and being received within the primary sheath lumen adjacent to the primary sheath distal end in a contracted delivery state. The delivery system may further include a length reference mechanism that indicates a length of the primary sheath distal end that extends distal to the secondary sheath distal end during the contracted delivery state of the prosthesis.
