摘要:
A surgical or wound closure device utilizes a slide fastener for rapidly closing a surgical incision or wound with precise apposition of the sides of the incision. The surgical closure devices are configured for linear incisions, shaped incisions, such as used for wedge biopsy or excisional biopsy, and long incisions, such as used for laparotomy or surgical removal of redundant skin. The surgical closure device may be adhered to the patient's skin prior to making an incision and is subsequently used for closing the incision.

摘要:
A biopsy incision closure device comprises a base having a frame incorporated therein. Together, the base and frame define an opening for performing a biopsy incision when the device is placed over a tissue surface. The base is typically composed of an elastomeric material and the frame comprises resilient inelastic members which can be used to close the opening in a highly uniform manner with minimum distortion and stress introduced into the tissue edges being drawn together.

摘要:
Prosthetic valves and their component parts are described, as are prosthetic valve delivery devices and methods for their use. The prosthetic valves are particularly adapted for use in percutaneous aortic valve replacement procedures. The delivery devices are particularly adapted for use in minimally invasive surgical procedures. The preferred delivery device includes a catheter having a deployment mechanism attached to its distal end, and a handle mechanism attached to its proximal end. A plurality of tethers are provided to selectively restrain the valve during deployment. A number of mechanisms for active deployment of partially expanded prosthetic valves are also described.
摘要:
Torque shafts and other related systems and methods are described herein. The torque shafts are both flexible and capable of transmitting torque. The torque shafts are useful for procedures that require torque and pushability to drive or deploy a device. The flexibility and pushability of the torque shafts enable them to curve along a tortuous path, and the torque transferring capability of the shafts enable them to transmit torque along the shaft.

摘要:
Described herein are systems and methods for operation of a prosthetic valve support structure (32) having additional reinforcement coupled with panels (36). Multiple support members (620) are distributed across the inner surface of the valve support structure (32) at regular intervals. Each support member (620) can include a looped portion (621) to act as a hinge (52). Each looped portion (621) is in a location coincidental with the interlace between adjacent panels (36).
