    摘要: A method and apparatus for removing a pre-placed prosthetic joint from a bone cavity and conditioning the cavity for receipt of a replacement joint. The pre-placed joint is first pulled from the mantle of hardened cement holding it within the cavity, thus leaving a cavity within the mantle. A mass of fluid cement is then placed within the cement cavity, after which a pulling tool is inserted into the fluid cement and the fluid cement is permitted to cure to bond with the hardened cement and form an integral mass. The pulling tool has detachable sections or sleeves, each with grip forming elements on its exterior and structure to connect a slap-hammer to its proximal end. Tension is then applied to the each section to remove the section and the cement mantle surrounding it from the bone cavity. The process is repeated for each section until all of the cement mantle is removed.

    摘要: A method and apparatus for removing a pre-placed prosthetic appliance anchored in place in a bone recess by a cement mantle and conditioning the recess for receipt of a replacement appliance. The preplaced appliance is first pulled from the mantle of hardened cement holding it within the recess, thus leaving a cavity within the mantle. A screw threaded post having nuts threadably engaged therewith at longitudinally spaced locations is then anchored within the cavity with a new mass of cement. Thereafter, the post is threadably disengaged from the nuts, leaving the nuts in place within the new mass of cement. A pulling tool is then successively engaged with the nuts and tensioned to incrementally remove the mantle from the recess.

    摘要: Systems and methods for controllably traversing a tissue wall. In one embodiment, a distal end of a catheter is positioned and/or repositioned utilizing direct visualization out the distal end of the catheter, as facilitated by an imaging element disposed within the distal tip of the catheter. An inflatable balloon may comprise a portion of the distal tip of the catheter for structural and/or visualization media purposes. A tissue traversing element may be forwarded through a working lumen defined by the catheter and controllably pushed through a tissue wall as observed with the imaging element. The tissue traversing element may comprise sensors and the like to facilitate monitoring of changes in pressure, color, oxygen saturation, flow rate, and echo timing, to determine the position of the tissue traversing member relative to the tissue wall.

    摘要: An inflatable retraction apparatus is provided for retracing an organ inside a body to gain access to an adjacent tissue. The apparatus includes an able chamber formed from a single thin envelope, and capable of being collapsed for insertion through an incision and being expanded to a predetermined shape for retracing the organ. An inflation mechanism is adapted to selectively inflate the chamber to the predetermined shape. The inflation mechanism includes at least one inflation tube attached to the inflatable chamber in fluid communication theretween, and an inflatable maintaining lattice operatively enveloping the inflatable chamber and in operative association with the inflation mechanism. The inflatable maintaining lattice defines a plurality of single layered access windows around the inflatable chamber, and is configured and adapted to maintain the inflatable chamber in substantially the predetermined shape after an aperture is pierced in at least one of the plurality of access windows of the inflatable chamber.
