摘要： A rotary shaver blade assembly having a laterally facing and end facing cutting window enabling it to resect tissue presented end-wise or at relatively small angles. The assembly is provided with a stationary elongated outer tube and a rotatable inner tube, both having laterally facing and end facing cutting windows and both having planar transverse end walls at their distal tips. The transverse end walls are abutting and are sharpened into edges by being tapered in opposite directions. The end wall of the outer tube is tapered into a concave surface to allow the inner and outer transverse edges to be situated close to target tissue. The edge on the end wall of the inner tube is transversely arcuate and has a point at each end to enable it, in cooperation with the outer edge, to resect tissue presented axially or at shallow angles to the axis of the shaver blade. A method for producing such a shaver blade assembly comprises the formation of intersecting arcuate surfaces to create the various aforementioned edges.

摘要： Conventional vasectomy techniques suffer from a number of disadvantages, including, for example, a substantial risk for the development of hematomas and swelling, a potential for spontaneous regeneration and undesired resumption of fertility, a need for a highly skilled surgical professional, as well as a long recovery period, accompanied by severe limitations on post-surgical activity. The present invention overcomes the disadvantages and deficiencies of the prior art by providing a rapid, reliable, less invasive male sterilization procedure as well as vasectomy instruments and kits for use therewith.

摘要： Disclosed herein is a distal end electrode assembly for use in connection with electrosurgical devices, particularly those adapted for the modification, sculpting, resection, removal, or vaporization of tissue, configured for coagulation, cauterization or hemostasis purposes, or utilized for thermal treatment of normal and tumorous tissues. In the context of the present invention, mechanical fastening means, epoxies and other high-temperature adhesives connecting electrode(s) to insulator(s) are replaced with brazed joints to yield electrosurgical devices capable of safely and reliably operating at high power densities and elevated temperatures without thermal failure of the bonds between the electrode and the insulator. The use of brazed joints further permits the construction of miniaturized, compact electrosurgical devices, of both monopolar and bipolar configurations, having utility in a number of divergent fields, from arthroscopy to otolaryngology to oncology, and applicable to both laparoscopic and open surgery techniques. Thus, active electrodes and electrosurgical devices of the present invention maximize efficiency, safety and reliability while minimizing manufacturing cost and device profile.

摘要： A method and device provides features for the temporary “parking” of sutures with respect to a cannula. In the preferred embodiments the features are slots that maintain tension on, and orientation of, sutures placed therein. The slots or features may be integral with the cannula or part of a separate device which may be removably affixed to the external portion of a cannula. In addition, the opening(s) used for instrument-passing are off-center, thereby reducing if not elimination outward sprays during use. The invention eliminates the multiple steps inherent in current suture management techniques for arthroscopic procedures, particularly rotator cuff repair and assists in tensioning/advancement of tissue into its repair site.

摘要： A process for simultaneously shaping and sharpening a cutting widow at the distal end of a tubular member of a rotary blade assembly. The assembly is provided with a stationary elongated outer tube, having a cutting window at its distal tip and includes a rotatable elongated inner tube having a cutting means at its distal tip. The window in the outer tube has a curvilinear profile defined by a peripheral rim surrounded entirely by a land surface which is inclined relative to the rim. The inclination of the land produces an area which tapers from a full thickness, where the land is adjacent to the cylindrical wall of the outer tube, to a sharp edge around the periphery of the window. The curvilinear window is produced by a manufacturing process which creates the window opening with a sharpened periphery at the same time that the land surrounding the opening is inclined. A preferred embodiment utilizes electrochemical grinding of the distal ends of the tubular member by a tool having a rotatable wheel with a perimeter in the shape of a groove of predetermined arcuate profile.
