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 stent (30) having an elongate tubular configuration is formed of a plurality of elongate elements (84) interwoven or braided to form a tubular configuration. The elements (84) may be relatively strong, and rigid, but movable relative to each other within the weave or braid in order to provide the stent with generally soft characteristics. The elements may be formed of different materials, such as an absorbent material permitting the stent to be doped with materials, such as drugs, and chemicals. Even the absorbency can be controlled, and varied to provide a predetermined time-release of the absorbent.

摘要： A fluid controlled device (10) is adapted for disposition in a body conduit where it controls the flow of body fluids within the conduit. A sleeve (60) is provided with a wall of separation having a first surface which defines a flow passage facilitating the flow of body fluids, and a second surface which defines an exclusion chamber sealed from the flow passage. Various dilators (46, 48) have properties for moving the seal between a low profile state facilitating insertion of the device, any high profile state defining the flow passage and exclusion chamber (67). The dilators (46, 48) may be skeletal, inflatable or porous. An associated method includes the step of dilating a dilation assembly to move a wall from a low profile, insertible state to a high profile wherein the wall defines a flow passage and an exclusion cavity.

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.

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.
摘要翻译：在具有钝头的线圈的构造中提供腹腔镜注气装置。该装置能够穿过腹壁而不切割组织，并且基本上平行于内表面离开腹壁。尽管盘绕装置的旋转导致通过腹壁的向前运动，但可以对该装置施加反作用力以在壁与内部器官之间形成安全空间。由于钝的远侧尖端，平行的出口角度和安全空间，在装置放置期间内部器官基本上没有威胁。进一步的空间可以通过使用压力气体产生腹腔来随后放置套管针。通过将盘绕的吹入装置可旋转地连接到套管针上，反作用力的优点不仅可以用于建立安全空间，而且还可以用抵抗隆起的反作用力将套管针拉入腹壁中。

摘要： A multi-seal trocar system (10) includes a plurality of co-axial sealing elements (30 60,80) adapted for forming a seal with either a large or small instrument. Small and large sealing elements (45,62) are disposed in an in-line arrangement such that a single port is provided for instrument insertion. A zero seal (80) is disposed distally of the sealing elements to seal a working channel of the system and to prevent backflow when no instruments are inserted. The small sealing element (45) is configured such that insertion of a large instrument automatically moves the small sealing element (45) out of its path, thereby avoiding contact with the large instrument.

摘要： A releasable mechanism such as a cap is adapted for use with an access sheath having an elongate tube and a handle structure disposed at a proximal end of the tube. The releasable mechanism is sized and configured to fit the handle structure, which is shaped like the bell of a horn, to further facilitate use with surgical instrumentation. The releasable mechanism may operate as a separate cap that snaps onto the handle structure to provide access pathways to the sheath. The releasable mechanism may also be disposed at a proximal end of a surgical instrument to be introduced into the access sheath such that it may be interlocked with the sheath. In a method of manufacturing a kink-resistant sheath, a wire is initially coated with a plastic material, the coated wire is then wrapped around a mandrel forming a plurality of windings, and the wound coated wire is heated until the plastic material melts and bonds the windings to form a wire-reinforced sheath. The plastic material is preferably polyurethane but may be a thermoplastic, a thermoset or any plastic material having hard and/or soft durometer. The wound coated wire may be heated by capturing the windings within a shrink tube or compressing the windings in a mold and heating the windings until the sheath is formed. In another aspect of the invention, a mandrel is used as part of an extrusion process. In another aspect of the invention, another coating or outside layer could be formed over the spring reinforcement by dipping in a solvent based solution. In yet another embodiment of the invention, a braid such as a polyester braid may be used instead of or in addition to the coil spring to form a kink-resistant sheath.

摘要： A trocar (18) is provided with a cannula (21) and a housing (23) and valve assembly (50) disposed in the housing (23) which forms a housing seal, and instrument seal, and in some cases a zero seal (58). A gel material (54) is included in the valve and provides the valve with superior flotation properties for maintaining the instrument seal even when the instrument is moved off-axis. In order to accommodate movement of the gel material (54), voids can be formed within the valve housing (23) and even within the gel material (54).
