    摘要: A surgical instrument is used for temporary use in a medical procedure in a mammalian body. The surgical instrument is configured to be changed between two shapes upon application of one or both of heating and cooling. The instrument includes a first member, a second member having a surface configured to contact tissue, and a means to apply heating or cooling to one or both of the first member and the second member to change the shape between a first shape and a second shape. A surgical instrument also may be configured to be changed between two shapes upon removal of a constraining force. The surgical instrument includes a first member, a second member having a surface configured to contact tissue, and a constraining means to apply a constraining force to one or both of the first member and the second member to cause one or both of the first member and the second member to be in a first constrained shape. The surgical instruments may be used in minimally invasive valve surgery.

    摘要: A racket includes a handle section, a head section, and a connecting section positioned between the handle section and the head section. One or more of the handle section, the head section, and the connecting section include a superelastic metal. The racket, other athletic devices and other devices containing superelastic components are capable of producing a spring force in response to a deflection. The superelastic components may improve the performance of rackets, athletic devices and other devices by increasing the contact duration between the active element of the device and objects against which the devices are configured to exert a force. The superelastic components also provide increased resistance to breakage or plastic deformation of the racket, athletic device or other devices, especially when exposed to frequent deflections. Superelastic components are able to decrease the weight of rackets, athletic devices, or other devices without sacrificing strength. The superelastic components also enable applying a specific spring force at a flex point of the racket to enhance the dynamic response resulting from a desired deflection.

    摘要: A catheter having a proximal portion and a distal portion terminating in a distal tip, is provided with a spring assembly contained within its distal tip portion for providing a bias against side to side deflection of the distal tip. The assembly preferably includes a central wire having a first diameter, which central wire extends from the proximal portion of the catheter to the distal portion, and a plurality of wires secured to the central wire adjacent the distal end thereof. Each of the wires is stranded together, preferably twisted helically, around the central wire and preferably has a second diameter substantially smaller than the first diameter. Alternatively, the stranded wires can be attached along and parallel to the larger diameter wire, and the latter wire is of a substantially greater length than the stranded wires.

    摘要: A tissue closure system can include a deployment instrument and a sealing element. The deployment instrument can be slidably mounted to and guided by a tubular medical device. The deployment instrument can be advanced over the tubular medical device to the desired location. The sealing element can then be advanced off of the end of the tool. The sealing element can include tissue engaging elements that are configured to automatically close upon deployment to bring together tissue. A slidably attached guided skin (or other tissue) cutter can also be used if desired to facilitate entry of the deployment instrument.

    摘要: A tissue cutting device includes a catheter with a window at its distal tip for admitting tissue into a catheter compartment. A cylindrical cartridge in the compartment has a cutting edge that supports an electrically conductive cutting element, e.g. a band or wire. The cutting element and adjacent tissue can be heated to a selected temperature by generating an electrical current through the cutting element. The catheter is maneuverable to position its distal end near the tissue to be cut. The catheter incorporates a dilatation balloon or other feature to urge the catheter against the tissue, so that at least part of the tissue may enter the compartment through the window. Then, the cartridge is manipulated from the catheter's proximal end to move the cutting edge across the window, cutting the tissue. According to alternative embodiments, the cartridge is either rotated or moved axially relative to the catheter and, in either event may be capable of closing the catheter window when the cut is complete. Further alternatives involve either placing an indifferent electrode on the patient and providing an RF signal via a single conductor to the cutting element for ohmic heating, or providing an RF (or a DC) current through the cutting element and two separate conductors for direct resistive heating of the cutting element.
