摘要： A surgical clamp includes opposing jaws and a covering enhancing traction between the jaws and a body conduit. A multiplicity of fibers oriented to extend longitudinally between the clamp and conduit may be composed of filaments and either woven or non-woven to form a fabric. A variety of weaves are contemplated to provide different textures, each having its own traction characteristics. The nature of the weave can control characteristics such as smoothness, absorption, and texture. The fibers or filaments may be formed from any solid or semi-solid material, adding its own characteristics to the resulting fabric insert or clamp.

摘要： A trocar having a working channel extending between a distal end and a proximal end is adapted for disposition across a body wall. A valve is disposed in the working channel so that an instrument inserted into the working channel extends through the valve resulting in undesirable friction forces. The valve is provided with a first wall which intersects a second wall to define a contact surface with an area less than the combined area of the first wall and second wall. This surface provides a substantially reduced contact with the instrument thereby reducing the friction forces and facilitating movement of the instrument through the working channel. An associated method includes the step of orienting the first wall and the second wall to provide the contact surface with the configuration of a line.

摘要： A trocar having a cannula and housing which define an access channel, is configured to receive a surgical instrument. A flexible valve disposed in the channel includes first portions which define an orifice through the valve and second portions which are disposed outwardly of the first portions. The second portions are provided with a greater flexibility so that when the instrument is inserted off-axis, the second portions of the valve will deform before the first portions causing the orifice to move without substantial deformation to the off-axis location. Alternatively, levers engaging the first portions of the valve can be pivotally mounted on a floating ring to move the substantially undeformed orifice to the off-axis location. An associated method includes the steps of deforming the second portions of the valve without substantially deforming the first portions of the valve to move the orifice into axial alignment with the instrument.

摘要： An apparatus is provided for sealing around shafts or tubes of varying diameter. Its basic element comprises an elastomeric sealing body with an axial passage which is radially compressed from more than two sides to compress the passage into sealing engagement with a member extending through the passage. Radial compression is achieved by cams and followers disposed around the body which cooperate with angularly spaced radially extending lugs formed integrally with the body. The cams are spring biased to normally compress the axial passage of the sealing body. Levers operable by one hand of the user are provided to selectively release the apparatus.

摘要： Access devices to facilitate the introduction of various surgical instruments into vessels, conduits, cavities, and other interior regions of the body are disclosed, which include a "duck bill" valve having at least three flexible fold sections or leaflets subtending 360.degree. degrees of the cylindrical wall portion. The valve is configured to provide reduced friction forces when an instrument is inserted, as well as zero closure characteristics when the instrument is removed.

摘要： The following specification discloses a breathing gas mask having an elastomeric or plastic main body portion supported by a head band formed with a number of supporting straps for holding the mask to a user's face. The mask has a large viewing lens with an elongated protuberance in the form of a bead extending around the periphery of the viewing lens for purposes of protecting the major lens surface from exposure to impacts and scratching when it is laid on its face. The mask incorporates an oral nasal interior breathing cover with a speaking diaphragm in adjacent relationship thereto to allow for the intake of breathing gas into the oral nasal mask area while allowing for exhalation through a poppet valve in connected relationship to the oral nasal mask. The outer mask seal incorporates a flared interior seal member around the inner periphery thereof which incorporates a compound curve having variable cross sectional shapes around the periphery thereof to allow for a tightened seal to a user's face.
