Title: Singleshot anastomosis instrument with detachable loading unit and method
Inventor: GRESHAM RICHARD D
IPC: A61B17/128
Filed: 1998-06-11
Granted: 2007-01-02
Abstract: There is disclosed a surgical instrument and loading unit for performing an anastomosis of first and second blood vessels. The surgical instrument includes a handle assembly and a body portion extending distally from the handle assembly. The detachable loading unit includes an anvil releasably engagable with a distal end of the body portion and having a plurality of fasteners disposed in channels about the circumference of a distal end of the anvil. A pusher is slidably mounted over the anvil such that distal movement of the pusher in response to actuation of the handle assembly cams the fasteners between the anvil and a distal end of the pusher to simultaneously crimp the fasteners about tissue. A method of performing an anastomosis is also disclosed and includes positioning a first vessel in the loading unit and partially inserting the first vessel through an opening in a second vessel. The surgical instrument is subsequently attached to the loading unit and the handle assembly is actuated to crimp fasteners about the first and second vessels to form an anastomosis.

Title: Vehicle mirror assembly
Inventor: BODDY IAN
IPC: B60R1/078
Filed: 1998-10-27
Granted: 2008-04-15
Abstract: The present invention relates to a rearview mirror assembly for installation on the side of a motor vehicle. The assembly comprises a fixed support structure constructed and arranged to be mounted on the side of the motor vehicle exterior such that the assembly extends laterally outwardly with respect to the vehicle. A mirror housing structure is mounted to the support structure for angular movement about a generally vertically extending axis with respect to the vehicle. A movable mirror housing is slidably mounted to the mounting structure. The housing has a mounting structure engaging surface engaging the mounting structure in tightly fit relation to prevent relative vibratory movements between the housing and the mounting structure as a result of vehicle vibrations. A mirror is mounted to the mirror housing. The mirror is positioned and configured to reflect images of objects disposed rearwardly of the mirror assembly to a drive seated within the vehicle. The tightly fit relation between the mounting structure engaging surface and the mounting structure is such that (1) the mirror housing can be manually repositioned laterally towards or away from the vehicle through an infinite range of positions while the mirror faces rearwardly with respect to the vehicle by manually applying lateral force to said housing directed towards or away from the vehicle sufficient to overcome the tightly fit relation without performing additional manual releasing steps and (2) the mirror housing will thereafter remain in a selected one of the positions absent application of lateral force to the housing sufficient to overcome the tightly fit relation without performing additional manual securing operations.

Abstract: An integrated optical biopsy forceps device and a method for tissue identification by optical analysis and biopsy sampling at a site within the body. The device includes an elongated catheter body for introduction into the body and navigation to an area of interest. An optical fiber extends through the device, from the proximal end, where it may be connected to electro-optical spectral analysis equipment, to a distal tip for illuminating and receiving light energy from tissue at the location of the tip. The distal end of the device has a pair of cutting jaws pivotally mounted at the distal end of the catheter body and controlled by control wires extending through the catheter body to a control handle at the proximal end, or by the optical fiber. The device may be spectroscopically guided to a site of interest within the body. The fiber tip is positioned coaxially with the jaws at the zone of contact and cutting of the jaws, and is retracted as the jaws close, so that the biopsy sample is taken exactly at the spot being viewed by the optical fiber.

Abstract: A graft copolymer comprising a backbone of a propylene polymer material having a vinyl monomer graft polymerized thereto is produced by (1) treating a propylene polymer material with a free radical polymerization initiator, (2) treating the propylene polymer material with at least one grafting monomer capable of being polymerized by free radicals, in the presence of a polymerization rate modifier, and (3) removing any unreacted grafting monomer from the graft copolymerized propylene polymer material, decomposing any unreacted initiator, and deactivating any residual free radicals in the material. Use of the polymerization rate modifier increases the polymerization induction time on the polymer surface, consequently facilitating monomer diffusion into the interior of the polymer particles so that surface polymerization of the monomer is inhibited.

Abstract: Interference and/or nonlinear distortions are reduced in a signal communicated from a transmitter to a receiver. To reduce interference, the transmitter is momentarily disrupted, during which time the receiver analyzes interference on the communication path to determine the frequency of at least one peak thereof. Information is communicated from the receiver to the transmitter identifying the frequencies of the interference peaks. Based on this information, the transmitter pre-distorts the signal to accentuate the signal magnitude at the identified frequencies. The pre-distorted signal is then communicated to the receiver, where it is filtered to attenuate the signal magnitude at the identified frequencies. An adaptive scheme periodically determines the interference peak frequencies. For nonlinear distortion cancellation (e.g., CSO/CTB), there is no need to disrupt the transmitter since the frequencies of the distortion are already known. Pre-distortion at the transmitter and filtering at the receiver are performed at the known, fixed frequencies.

Granted: 2004-06-08
Abstract: An SQL relational database management system which determines the shareable status of an executable object (section) in an SQL cache. The shareable status is defined for a section in an SQL cache by the system maintaining an identification list which has reference to database entities which are affected by a DDL statement in the current unit of work. When an SQL  statement is compiled, the compiler generates a list of dependencies, which list is compared with the identification list. If the SQL statement data dependencies are on the identification list, the SQL  statement will be treated as non-shareable until the completion of the current unit of work.
