摘要： A medical device includes a control handle, an end effector, and a passive articulating joint connecting the end effector to the handle. The handle has a stapling actuator, an articulation joint actuator different from the stapling actuator, and a body through which the stapling and articulation joint actuators traverse. The end effector has an anvil, a stapler cartridge with staples, and an anvil-cartridge control device connected thereto and to the stapling actuator and staples when the stapling actuator is actuated. The stapling actuator passes through the articulating joint and flexes correspondingly to articulation of the articulating joint. The articulation joint actuator, when unactuated, holds the articulation joint and, thereby, the end effector, in a substantially fixed articulation position, and, when actuated, releases the articulation joint into its freely articulating state to permit free articulation of the end effector dependent upon external forces acting upon the end effector.

摘要： A compression-self-adjusting staple includes a substantially U-shaped staple body and a compression device. The staple body has a bridge and two legs extending from the bridge at an angle thereto. Each of the legs has a base end integral with the bridge and a deformable distal end defining a stapling point shaped to pierce material to be stapled. The compression device is at least partly disposed between the legs and has a bias portion with a compression surface movably disposed between the legs and a compression resistor connected to the bridge and to the compression surface and formed to resist movement of the compression surface towards the bridge with a force.

摘要： A clip applier includes a flexible coil with a manual actuator coupled to one end and a jaw assembly coupled to the other end. A store of clips is adjacent to the jaw assembly and a clip pusher is adjacent to the store of clips. The actuator includes a lever for opening and closing the jaws, a knob for rotating the jaw assembly, and a crank for dispensing clips. The knob and the lever are coupled to a single control member which extends through the coil to a joiner where it is joined to a pair of pull wires coupled to the jaws. The crank is coupled to a second control member which is threaded along a portion. The threaded portion engages a threaded member coupled to the pusher such that rotation of the threaded control member by the crank causes the pusher to be moved distally.

摘要： Carboxylate salts of amines are used as components of heat exchange fluids. The amines may have a ratio of N to C of 1:0 to 1:12 and the carboxylate anion may be derived from an acid of the formula H(CH2)0-3COOH. A preferred monoamine heat exchange fluid utilizes triethanolamine formate. Lower carboxylate salts of diamines and triamines having the formula R2[N[(CH2)mNR]1-2]R where each R is independently selected from moieties of the formula —CnH2n+1 and moieties of the formula H[O(CH2)1-4]—, each m is independently a number from 1 to 6, and each n is a number from 1 to 4, are disclosed as compounds.

摘要： A surgical snare instrument according to several embodiments includes a first handle capable of controlling the rotational position of the snare, and a second handle adapted to control the opening and closing of the snare and cauterization. The first handle serves as a grippable element on the sheath and contains a system which rotates the shaft, and consequently the snare, so that when the physician grips the first handle, the physician is capable of steering the snare by operating the first handle. In addition, the physician is also capable of positioning the entire sheath relative to the endoscope by sliding the sheath into and out of the working channel of the endoscope. The proximal handle is operable by an assistant and permits longitudinal movement of the shaft and cautery application. According to other embodiments, the snare instrument is provided with a mount which enables the snare instrument to be adjustably fixed relative to an endoscope handle. Additionally, an embodiment is also provided in which a single handle provides a physician with a system which advances and retracts the sheath of the snare instrument relative to the endoscope, a system which opens and closes the snare, and a system which rotates the shaft and the snare to position the snare over a polyp.

摘要： A surgical instrument includes an end effector having a clevis and first and second jaws mutually rotatable between open and closed positions. The jaws are proximally directed and laterally displaced relative to a longitudinal axis of a control shaft of the instrument. The jaws hold first and second parts of a fastener, respectively. The first part includes a base having upstanding tissue piercing posts, and the second part includes another base defining apertures for receiving the posts, as well as a portion movable relative to the second base. When the upstanding posts are inserted into the apertures, the movable portion can be moved into a second configuration to lock the parts of the fastener together. The instrument is adapted to move the second part into the second configuration. A method for using the apparatus and fastener are also provided.

摘要： An endoscopic instrument has a portion having an outer surface with a non-circular cross-sectional shape. The non-circular cross-sectional shape may be provided to the instrument by providing peripheral projections or fins along the length of the portion or by providing the periphery of the portion with a polygonal shape. Where fins are used, the fins are preferably quite small and only have a minimal effect on the fluid flow cross sectional area between the interior of the working channel and the endoscopic instrument. The resulting instrument has significantly reduced backlash while maintaining adequate fluid flow in the working channel. According to a second embodiment of the invention, a portion of the interior of the working channel of the endoscope has an interior surface having a non-circular cross sectional shape by the inclusion of a plurality of radially spaced and inwardly directed ribs or by being polygonally shaped. The resulting endoscope reduces the backlash of an endoscopic instrument inserted therein while maintaining adequate fluid flow in the working channel.

摘要： An implantable radiation therapy device includes a biocompatible radiotranslucent outer capsule containing a radiation shielding element and a radioactive isotope at least partially shielded by the shielding element. When the device is at or below body temperature, radiation is prevented or limited from being transmitted through the outer capsule by the shielding element. When non-ambient energy is applied to the device, the shielding element and radioactive isotope are reconfigured such that an increased level of radiation is transmitted through the outer capsule and emitted by the device.

摘要： A hybrid rocket motor is provided with a precombustion chamber supplied with propellant from separate fuel and oxidizer sources. The propellant can be in the form of gas or liquid and injected substantially tangentially into the head end of the hybrid motor adjacent the oxidizer injector to form a propellant swirl. As the hybrid motor oxidizer is injected into the swirl, it is heated and gasified, and assumes a swirling motion which increases the oxidizer path length and thereby increases the dwell time of the oxidizer. The increased dwell time increases combustion efficiency and permits multiple restarts of the hybrid motor. The propellant may also be a combination of solid and fluid reactants. In one embodiment, the oxidizer injector is extended into the combustion chamber to form a toroidal precombustion chamber which has an annular nozzle adjacent a face of the oxidizer injector.
