Filed:

Apr 17, 1991

Appl. No.:

7/686901

Inventors:

K. Mosaddeq Hossain - Hillsborough NJ

Assignee:

Site Microsurgical Systems, Inc. - Horsham PA

International Classification:

A61M 100
F04B 4308

US Classification:

604 34

Abstract:

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.

International Classification:

A61B 1702

US Classification:

128 20

Abstract:

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.

International Classification:

F04B 4308

US Classification:

417 53

Abstract:

A pump and a method for pumping liquid or fluid through a pair of resilient tubes includes a pushing mechanism which partially compresses the tubes in a balanced, alternating, rocking manner. The resilient tubes are held in a parallel relationship. The pushing mechanism alternately compresses the tubes. As one of the two parallel tubes is compressed, fluid is pumped out of the tube and at the same time fluid is drawn into the second tube as the latter tube resumes its original shape. The resilience of both tubes also is used to assist the pumping action in a balanced fashion, thereby providing a pump that has low power consumption and is lightweight.

International Classification:

A61B 1736

US Classification:

606 17

Abstract:

A laser medical device for delivering energy to tissue to be treated. The device includes a laser energy transmitting conduit having a longitudinal axis, and has a proximal end for connection to a source of laser energy and a distal end from which laser energy transmitted by the conduit is emitted. A laser energy redirecting member is located adjacent the distal end of the conduit for redirecting the laser energy in a lateral direction with respect to the axis of the conduit, and a tissue contact member is provided adjacent the laser energy redirecting member. The tissue contact member has a transverse cross section of preselected shape and a longitudinal axis generally transverse to the axis of the conduit. The tissue contact member further has an input surface for receiving laser energy redirected by the laser energy redirecting member and transmitting the laser energy received from the laser energy redirecting member. The tissue contact member terminates in a tissue contact surface having a radius of curvature.
