    摘要： A handpowered, low cost, disposable laparoscopic surgical tool has a proximal hand engageable unit, an elongate extension unit and a distal jaw unit. Pulling a trigger of the hand engageable unit forwards an extension rod in the extension unit to pivot the jaws together. In one embodiment of the invention, the handle unit is primarily of molded plastic material for low cost and disposability. In an embodiment, electrocautery contact with the extension unit is through a bendable spring element. In an embodiment specially shaped links and connected jaw portions improve strength and control in opening and closing the jaws.

    摘要： A method of repairing a bone fracture comprises accessing a fracture along a length of a bone through a bony protuberance at an access point near an end of a bone. A bone fixation device is advanced into a space through the access point at the end of the bone. A portion of the bone fixation device is bent along its length to traverse the fracture. The bone fixation device is locked into place within the space of the bone.

    摘要： A bone fixation device is provided with an elongate body having a longitudinal axis and having a first state in which at least a portion of the body is flexible and a second state in which the body is generally rigid, an actuateable gripper disposed at one or more locations on the elongated body, a hub located on a proximal end of the elongated body, and an actuator operably connected to the gripper(s) to deploy the gripper(s) from a retracted configuration to an expanded configuration. Methods of repairing a fracture of a bone are also disclosed. One such method comprises inserting a bone fixation device into an intramedullary space of the bone to place at least a portion of an elongate body of the fixation device in a flexible state on one side of the fracture and at least a portion of a hub on another side of the fracture, and operating an actuator to deploy at least one gripper of the fixation device to engage an inner surface of the intramedullary space to anchor the fixation device to the bone. Various hub designs are disclosed that may be used in combination with other fixation device components.

    摘要： An ultrathin selectively permeable membrane made by glow discharge plasma polymerization of a single siloxane monomer with the deposition of the polymer as a single layer upon a nonporous support material. The resulting membrane has an oxygen content between about 10% and 60% and is highly permselective. The support material can be an electrode, thereby forming an electrode that is resistant to fouling or contamination but readily accessible to oxygen.

    摘要： Exemplary embodiments are directed to an augment and methods of implanting an augment. The methods include inserting the augment into a bone cavity of a bone of a host. The augment includes a body with an outer surface and at least one hole preformed in the body. The method includes introducing a fastener from an outer surface of the bone into a hole formed in the bone and engaging the fastener with the hole of the bone. The method includes passing the fastener through the hole of the bone. The method includes introducing into and engaging the fastener with the at least one hole in the body of the augment to fixate the augment within the bone cavity.
