  • Publication number: 20130030418
    Abstract: Embodiments of crimping devices for crimping stented prosthetic valves and other medical devices from a larger, expanded diameter to a smaller, crimped diameter are disclosed. Some crimping devices utilize a conical surface extending out-of-plane from the direction of crimping, where motion of the conical surface in the out-of-plane direction causes in-plane radially crimping. Other crimping devices comprise a funnel-shaped rigid body having a tapered inner lumen that compresses a medical device moving therethrough. Some funnel-shaped embodiments have slotted sides that allow portions of the medical device to project therethrough. Other funnel-shaped embodiments are used with a tubular sock to pull the medical device through the tapered lumen. Other crimping devices utilize rotating rollers that compress a medical device while the medical device spins between the rollers.

  • Publication number: 20110022165
    Abstract: The present disclosure concerns embodiments of an introducer that is adapted to facilitate insertion of a prosthetic device, such as a prosthetic heart valve, into a patient's vasculature. In one embodiment, the introducer comprises an elongated body defining a central lumen extending between distal and proximal ends of the body. The introducer body can also have a longitudinally extending gap extending along the length of the body between the distal end proximal ends. The gap in the introducer allows a user to place the introducer around implant sutures by passing the sutures through the gap and into the central lumen. Similarly, the gap allows the introducer to be easily removed from the sutures and/or a delivery device by passing them outwardly through the gap.
