Abstract:
An apparatus including a light source provides for intracranial treatment of a tissue region of a brain of a patient. The intracranial treatment apparatus comprises an outer shaft having a proximal end and a distal end for positioning within the tissue region of the brain. The outer shaft defines a lumen extending between the proximal end and the distal end of the outer shaft and having at least one aperture adjacent the distal end of the outer shaft. An inner light-delivery element having a distal end and a proximal end is adapted to be operatively connected to the light source. The light-delivery element is configured to be received within the lumen and extend from the proximal end of the shaft to adjacent the distal end of the shaft. The light-delivery element is adapted to deliver light from the light source through the at least one aperture of the outer shaft to the tissue region of the brain in proximity to the distal end of the outer shaft.
Abstract:
Es wird eine Kryospitze mit distalem und proximalem Ende zur therapeutischen Kältebehandlung von Gewebe beschrieben, die einen röhrenförmigen Körper und einen Fluidkanal, der innerhalb der Kryospitze das proximale und das distale Ende verbindet und so ausgebildet ist, dass er ein kryogenes Fluid leiten kann; und eine Verbreiterung des Fluidkanals am distalen Ende, welche am Abschluss des distalen Endes der Kryospitze, der einen elastischen Rand aufweist, in eine Öffnung mündet, welche kraftschlüssig auf das zu behandelnde Gewebe aufgebracht werden kann, aufweist.
Abstract:
A surgical device and procedure for accessing tissue to perform microsurgery, including a capsulotomy of a lens capsule of an eye. The device includes a handpiece with a tip for insertion into an incision. A sliding element is disposed within the handpiece and a suction cup is mounted to the sliding element. The sliding element can be translated to move the suction cup into and out of the handpiece. A compression mechanism associated with the suction cup and the handpiece compresses the suction cup for deployment through the tip of the handpiece. The suction cup can expand inside the anterior chamber into a cutting position. A cutting element mounted to the suction cup is used to cut a portion and to remove the portion. The cutting element may be mounted to a cutting element support structure in a way that prevents heating of the device.
Abstract:
A method and delivery system are disclosed for creating an aqueous flow pathway in the trabecular meshwork, juxtacanalicular trabecular meshwork and Schlemm's canal of an eye for reducing elevated intraocular pressure. Pulsed laser radiation is delivered from the distal end of a fiber-optic probe sufficient to cause photoablation of selected portions of the trabecular meshwork, the juxtacanalicular trabecular meshwork and an inner wall of Schlemm's canal in the target site. The fiber-optic probe may be advanced so as to create an aperture in the inner wall of Schlemm's canal in which fluid from the anterior chamber of the eye flows. The method and delivery system may further be used on any tissue types in the body.
Abstract:
A protection device for use in oral surgery. The device comprises; a body having a first part which locates outside a patient's mouth and a second part which, during use, locates inside the mouth. The body is arranged such that at least a part of the body is resiliency deformable to enable manual shaping to accommodate an anatomical shape of at least part of a patient's mouth, thereby providing a physical barrier between surgical instrumentation and a patient's soft tissue.
Abstract:
To provide a multi-layer resin film having outstanding oxygen gas barrier properties and moistureproofness. This multi-layer resin film is composed of a biaxially oriented polypropylene resin layer containing 10-40 wt% of a high crystallization resin and 6-15 wt% of a petroleum resin, and a polyvinyl alcohol resin layer laminated on at least one side of the former through an adhesive layer. In addition, the multi-layer resin film is characterized in that the oxygen transmittance at a relative humidity of 85% RH(request response header) and at a temperature of 23[deg.]C is 600 ml/m 2 xday x MP(methyl propionate)a or less and the water vapor transmittance at a relative temperature of 90[deg.]C and a temperature of 40[deg.]C is 3.5 g/m 2 x day x 20 [mu]m or less. Thus the obtained multi-layer resin film which does not contain chlorine and has outstanding oxygen gas barrier properties and moistureproofness, is best-suited for use as a film for packaging, in particular, packaging foods.
Abstract:
Intra-oral element for application of energy delivery treatments in jawbone, gums or other tissues inside the mouth, comprising a main body (2) attached to a cable (3) that connects it to the energy equipment and to a shaft (4) with a head (5) at its distal end where it incorporates the energy application means (6), formed by electrodes, electric resistances, or a combination of both. It also incorporates a temperature sensor (7), means for quantitative measurement of the energy delivered, and a screen (8) displaying the temperature and/or power, control buttons (9) and emergency stop button (10). The main body (2) is a handle-shaped housing. The shaft (4) is removable and the head (5) is provided with an adapter (51), formed by a conductive medium with flexible structure.
Abstract:
A fluid evacuation device is attachable to a hand-held instrument to provide the hand-held instrument with fluid evacuation capabilities. The fluid evacuation device includes a nozzle, a hose mount, and an evacuation hose. The nozzle has a receptacle that receives a portion of a hand-held instrument therein. The distal end of the nozzle has an opening therein through which fluid may be drawn into the nozzle. The fluid can pass through a flow region in the nozzle. The hose mount extends from the nozzle and connects the hose to the nozzle. The hose mount includes a passageway through which the fluid can pass from the flow region into the evacuation hose.
Abstract:
A point of incision is created within tissue, the tissue having a temporoparietal fascia-deep temporoparietal fascia layer (TPF-sDTF) beneath skin and a temporal branch of a target nerve extending along a portion of the TPF-sDTF, the point of incision being laterally displaced from the target nerve. A cryogenic probe having a distal tip extending from an elongated body is inserted into the point of incision. The TPF-sDTF is bluntly dissected using the cryogenic probe such that a treating portion of the cryogenic probe is directly adjacent to a first treatment portion of the target nerve. The cryogenic probe is activated to create a first treatment zone at the first treatment portion of the target nerve to cause a therapeutic effect.
