US Patent:

55778917, Nov 26, 1996

Filed:

Oct 14, 1994

Appl. No.:

8/322483

Inventors:

Michael H. Loughnane - Lafayette Hill PA
Kenneth P. Cook - Blue Bell PA

Assignee:

Instech Laboratories, Inc. - Plymouth Meeting PA

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.

Appl. No.:

6/383635

Inventors:

Kenneth P. Cook - Blue Bell PA

Assignee:

Site Microsurgical Systems, Inc. - Horsham PA

International Classification:

A61M 100

US Classification:

604 27

Abstract:

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.

Appl. No.:

7/118255

Inventors:

Kenneth P. Cook - Blue Bell PA
Robert M. Bross - Ivyland PA

Assignee:

Surgical Laser Technologies, Inc. - Erlanger KY

International Classification:

A61B 1736

US Classification:

606 2

Abstract:

A fluid supply system for gas and sterile liquids consisting of a disposable sterile cartridge that is connected to gas and liquid sources and a common exhaust. The cartridge cooperates with a rotating bearing assembly which pumps the liquid through the system without ever contacting the liquid. The gas sources are provided with means for supplying the gas under pressure to the cartridge. A suitable control selects either the gas or liquid source and a pair of gauges monitor the flow rates of the fluids.

Appl. No.:

8/925368

Inventors:

Kenneth Price Cook - Blue Bell PA
Robert Michael Bross - Ivyland PA

Assignee:

Surgical Laser Technologies, Inc. - Montgomeryville PA

International Classification:

A61N 506

US Classification:

606 6

Abstract:

A laser photo optic breakdown probe and handpiece system especially suited for small-incision cataract removal including an optical fiber through which a pulsed source of laser energy is delivered to a target spaced from the distal end of the fiber. The fiber is routed through a first guide tube with the target mounted at an angle on the end thereof. Holes are provided in the guide tube for the flow of infusion fluid therethrough. A second aspiration tube surrounds and provides rigidity to the guide tube, shields the distal end of the fiber and target, and serves as a channel for aspirated fluids and dislodged cataractous material. The guide tube is affixed to a transfer housing to which infusion and aspiration connections are made. The aspiration tube forms part of a handle assembly which is detachably coupled to the transfer housing.

Inventors:

Kenneth P. Cook - Blue Bell PA

Assignee:

Site Microsurgical Systems, Inc. - Horsham PA

International Classification:

A61M 100

US Classification:

604 34

Abstract:

A cassette assembly for a microsurgical system. The cassette comprises a body portion, a collection vessel and a suction conduit which may be occluded to interrupt suction. The cassette may also include an occludable infusion conduit for providing infusion through the cassette to a surgical site.

Appl. No.:

7/596816

Inventors:

Kenneth P. Cook - Blue Bell PA
Robert M. Bross - Ivyland PA

Assignee:

Surgical Laser Technologies, Inc. - Malvern PA

International Classification:

A61B 1736

US Classification:

606 15

Abstract:

A handpiece for use with laser surgical contact scalpels having a housing or handle portion with a laser enabling button thereon whereby a surgeon may expeditiously cycle the laser between its on and off conditions. The handpiece further including a mechanism for facilitating the longitudinal and rotational adjustment of the surgical scalpel with respect to the handle whereby optical fiber torque may be relieved and whereby the surgical tip may be oriented properly with respect to the laser actuation button. The adjustment mechanism includes torsional and longitudinal travel limits to protect button interconnect wires and means for locking the mechanism thereby to fix the relative positions of the scalpel and handle. The laser enabling button and associated circuitry including a low voltage self-contained power source and, further, optical isolation from the laser source whereby the laser may be cycled by the surgeon through use of the handpiece button without danger of electrical shock to the patient.
