摘要： The invention is directed to a trocar assembly having a channel defined along an elongate axis, the trocar assembly comprising a septum seal (60) disposed in the channel including a seal tip (60a) having a proximal facing surface, the seal tip including portions defining an orifice; and a septum shield (70) including a tubular member having a proximal end and a distal end, and a plurality of blades or leaflets protruding distally from the distal end of the tubular member, the septum shield being placed inside the septum seal such that the blades engage the proximal facing surface of the seal tip. The septum shield operates to reduce the drag force and to minimize axial movement of the septum shield and the instrument during insertion and removal of the instrument through the septum seal.

摘要： A process of making a tack-free gel is disclosed comprising the steps of providing a mold defining a mold cavity, the mold cavity comprising a plastic material; pouring or injecting a molten gel having a high molding temperature into the mold cavity; and forming the tack-free gel as a thin layer of plastic of the mold cavity is melted over the gel. The forming step further comprises cooling the gel from the molten state to a solidified state. The melting temperature of the plastic material is lower than the molding temperature of the gel; and the higher the temperature differential, the greater the melting of the plastic material and the thicker the layer of the plastic material on the surface of the gel. The mold may be formed of low-density polyethylene (LDPE). With the process of the invention, the heat of the molten gel at its molding temperature is transferred to the surface of the LDPE mold so as to melt a thin layer of the LDPE. The mold may comprise a mold base having a plurality of mold holes forming a plurality of mold cavities, each of the mold holes comprising an axial pin to mold an axial hole through a center of the gel, an LDPE cylinder providing a predetermined inside diameter for the mold, and an LDPE disc mounted on the axial pin and disposed at the bottom of each mold cavity in the mold base. The process may further comprise the step of dabbing the gel in a low-friction powder such as polytetrafluoroethylene (PTFE) and a lubricant. The mold may further comprise a mold top disposed axially of the mold base and comprises a plurality of holes forming a plurality of cavities, each of the mold top holes is adapted to receive the LDPE cylinder, and a second LDPE disc disposed at the top of each mold cavity of the mold top.

摘要： An echogenic medical device such as a stent for insertion into a biological tissue or vessel comprising an elongate tube and having at least one lumen extending substantially along a longitudinal axis. The elongate tube comprises a material having an acoustic impedance different from the acoustic impedance of the biological tissue or vessel of a patient body such that ultrasonic imaging of the tube inside the patient’s body may be achieved. The elongate tube may comprise a plastic material such as polyethylene or any formable, pliable material which may be molded and/or extruded to a variety of shapes depending upon a specific application. The invention improves ultrasonic imaging by entrapping air in a lumen of the stent, which may have any cross-sectional shape and which may be sealed anywhere along the longitudinal axis. The stent may include curled ends for positioning the stent in a body vessel, a plurality of holes for draining fluid in a body tissue, and additional lumen to entrap air and to further enhance ultrasonic imaging of the stent. The coils of the curled ends may also be tightly spaced together to provide ultrasound reflection. In another aspect of the invention, a material such as a foaming agent may be added during the extrusion process to cause the formation of CO 2 gas to form in the material as it is being extruded. In yet another aspect of the invention, a mesh stent may be used to advantage either by modifying the individual elements to be more echogenic or by adjusting the braid configuration to be more reflective.

摘要： A catheter having an elongate drainage tube with a proximal end and a distal end, is adapted to extend through a body conduit and into a body cavity. An anchor disposed the distal end of the tube is disposed in the body cavity and is adapted to be moved from an insertion position to a withdrawal position. The anchor in the insertion position has a low profile when the tube is moved distally and in the withdrawal position has a low profile when the tube is moved proximally. The first end of the anchor is attached to the tube, and a tension member is provided to extend distally of the tube to releasably hold the second end of the anchor in a fixed relationship with the tube. In an associated method, this tension member is severed to release the second end of the anchor from the tube and permit withdrawal of the tube and the anchor in a low-profile state.

摘要： A surgical retractor (10) is adapted for use in opening an incision (12) in a body wall (14) to facilitate access into a body cavity. The retractor includes an interior anchor (16) that is disposed interiorly of the body wall and an exterior tensioning device (56) that is disposed exteriorly of the body wall. At least one tension element (21) is coupled to the interior anchor and adapted to pass through the incision to engage the exterior tensioning device. Engaging elements (59, 62) are provided on the exterior tensioning device to engage the tension element and to maintain a tensile force on the tension element as it passes through the incision. Multiple concentric rings can also be used to maintain a tensile force on the tension element.

摘要： A laparoscopic insufflation device is provided in the configuration of a coil with a blunt tip. The device is capable of passing through the abdominal wall without cutting tissue, and exiting the abdominal wall substantially parallel to the inner surface. While rotation of the coiled device results in forward movement through the abdominal wall, a counter force can be applied to the device to create a safety space between the wall and the interior organs With the blunt distal tip, parallel exit angle, and safety space, there is substantially no threat to the interior organs during placement of the device. Further space can be generated with the use of pressured gas to produce an abdominal cavity for the subsequent placement of trocars. By rotatably attaching the coiled insufflation device to a trocar, the advantage of a counter force can be used not only to establish the safety space but also to pull the trocar into the abdominal wall with a counterforce which resists tenting.

摘要： A surgical access device, such as a trocar (10), includes a pendent valve (40) having an elongate structure (50) extending from a proximal end to a septum valve (56) disposed at a distal end. In operation, the elongate structure (50) follows the angle of the instrument (21) to pre-position the septum valve (56) into the path of the instrument (21) where it is not significantly challenged during instrument insertion or manipulation. The pendant valve (40) can be made to float at both the proximal end and the distal end of the elongate structure (50), to further reduce the vulnerability of the septum valve (56). Since the valve (56) is less vulnerable to instrument insertion (21), it can be formed to minimize friction and maximize the functional range of the access device.

摘要： A surgical obturator (18) adapted to penetrate a body wall comprising an elongate shaft (21) extending along an axis between a proximal end and a distal end, and a bladeless tip (27) disposed at the distal end of the shaft (21) having a conical surface (60) forming proximally into an outer surface, the outer space extending distally to a blunt point and having a pair of side sections. The side sections extend from the blunt point radially outwardly with progressive positions proximally along the axis. The conical surface (60) facilitates insertion of the obturator with a reduced penetration force and minimizes tenting of the body wall. The conical surface (60) further facilitates separation of different layers of the body wall and provides proper alignment of the tip between the layers. The surgical obturator (18) may be constructed from a disposable or reusable material such as a metal or an autoclavable polymer.
