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： A glucose measuring system includes a glucose meter that incorporates wireless communication capabilities. The meter can advantageously be a low cost meter by eliminating expensive components, such as the display. The user nevertheless is able to retrieve and view his or her glucose values by referring to displays within the glucose measuring local area network. Feedback via these displays can advantageously be used by the diabetic to create a higher level of confidence and safety.

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 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 surgical irrigation system is suitable for endoscopic and other surgical procedures. A hand held handpiece has a forward protruding hollow tip for supplying irrigation liquid to a surgical site, a hand actuable control for controlling irrigation liquid flow to the tip, and an irrigation liquid inlet. A self contained pumping unit is locatable adjacent a source of irrigation liquid and remote from the handpiece. The pumping unit comprises a housing containing an outlet for irrigation liquid, a pumping member for pumping irrigation liquid through the outlet, a motor for driving the pumping member, and an electric battery assembly for energizing the motor. An elongate tube connects the pumping outlet to the handpiece irrigation liquid inlet for supplying pumped irrigation liquid to the handpiece.
