    摘要: An iris dilator includes a body formed of an expansile material being expandable from a dehydrated first size and shape to a hydrated second size and shape. When hydrated, the dilator has a shape complementary to an inside diameter of the iris and a size sufficient to dilate the iris. In addition, a mammalian iris may be dilated by inserting the at least partially dehydrated iris dilator described above into a position radially inwardly from the iris where, in the presence of bodily or surgical fluids, the dilator hydrates and expands to engage and dilate the iris. An apparatus for deforming the dilator to facilitate insertion in use includes top and bottom surfaces which engage top and bottom sides of the dilator, respectively, at least one depression member for forming a depressed area on an edge of the dilator and at least one retainer member for retaining a non-depressed area on the edge of the dilator.

    摘要: A microsurgical irrigation/aspiration system is provided, including a controller having a pump roller head, actuators for occluding fluid lines, a suction sensor, and means for mounting a pump cassette. The system cassette is suitable for mounting on the controller and has an opening with a pump segment passing along an arcuate wall of the opening. When the cassette is mounted on the console, the roller head is engaged in the cassette opening and compresses the pump segment against the arcuate wall. An infusion line passes through the cassette and is occludable by one of the actuators, and a vent line connected to the pump segment is occludable by a second actuator. A suction sensing port on the cassette couples with the suction sensor in the controller. In an alternate embodiment, a cassette is disclosed within which both vacuum and peristaltic pumping is possible. Latching may be accomplished by a plunger attached to the sensory port of the cassette.

    摘要: A microsurgical irrigation/aspiration system is provided, including a controller having a pump roller head, actuators for occluding tubing, a suction sensor, and apparatus for mounting a pump cassette. The system cassette is suitable for mounting on the controller and has an opening with a pump tubing segment passing along an arcuate wall of the opening. When the cassette is mounted on the console, the roller head is engaged in the cassette opening and compresses the pump tubing segment against the arcuate wall. An infusion line passes through the cassette and is occludable by one of the actuators, and a vent line connected to the pump tubing segment is occludable by a second actuator. A suction sensing port on the cassette couples with the suction sensor in the controller.

    摘要: A microsurgery system comprising an instrument including a source of vacuum and control means, a remotely connected handpiece adapted to be disposed in the vicinity of the situs of the surgery and including an inlet and suction conduit means coupled to the inlet and to the vacuum source for carrying material away from the surgery situs. The system also includes a cassette assembly arranged for releasable securement to the instrument. The control means of the instrument includes an interrupter bar which cooperates with the cassette assembly for selectively isolating the vacuum source from the suction conduit means. The cassette assembly comprises a body portion, a collection vessel, a first port communicating with the suction conduit and a second port communicating with the vacuum source. Occludable conduit means are coupled between the first and second ports and are arranged to be engaged by the interrupter bar in response to a first signal to isolate the vacuum source from the suction means. The collection vessel is coupled to the suction conduit to collect the material extracted from the surgery situs. The cassette also includes similar means for enabling or disabling the flow of infusion liquid through an infusion line to the surgery situs. A hydrophobic filter and a check valve are also located within the cassette assembly.

    摘要: The disposable adaptor to permit aspiration and/or irrigation fluid to pass through an ultrasonic surgical instrument without permitting leakage of the fluid from or into the interior of the instrument. The adaptor includes a generally annular housing defining a lumen for receiving the horn of the ultrasonic instrument and having inner seals forming a seal between the confronting surface of the adaptor and horn for prohibiting leakage along the exterior wall of the horn and an outer seal for forming a tight seal between the confronting surface of the adaptor and the instrument shroud for prohibiting leakage along the exterior surface of the adaptor. The adaptor includes a flange at its distal end with a circumferential groove extending partially about the adaptor and cooperating with a mating projection on the distal end of the instrument shroud to provide rotational orientation for the adaptor with respect to the shroud.

    摘要: A laser catheter for the treatment of lesions and plaque deposits in arteries and other narrow paths having a radiation assembly affixed to a flexible conduit. The conduit generally includes multiple lumens for the passage of an optical fiber, a guide wire, a cooling medium therethrough, or fluid for inflating an angioplasty balloon. The radiation assembly is of short longitudinal profile and includes a generally spherical laser contact member retained within a housing, the latter affixed to the flexible conduit. The radiation assembly provides a dual-mode ablation/melting treatment regime. A longitudinal channel is provided through and along one side of the contact member thereby to permit guide wire positioning of the laser catheter while routing the guide wire away from the laser energy to avoid damage thereto. A balloon, in fluid communication with a catheter lumen, may be positioned rearwardly of the radiation assembly for secondary balloon angioplasty operations.
