  • Patent number: 5599299
    Abstract: Multi-lumen catheters are intended for advancement through the accessory channel on endoscope into a body passage into the gastrointestinal system. The catheters have two or more independent lumens extending continuously to ports at the distal tip for injection of a contrast medium simultaneously with a guide wire for ERCP procedures and for passage of accessories such as visualization devices, polypectomy snares, cytology brushes, papillotomes and stone baskets for catheterization, diagnosis and treatment within the biliary tract. Use of balloons for maintaining a catheter in fixed position in the biliary tract and for dilatation is also disclosed. The catheters employed are extrusions of a resin comprised of nylon and PEBA. The catheters may also be extruded from polyurethane. Multi-lumen catheters having a reduced diameter distal tip portion on which a dilatation balloon is located are also disclosed. The reduced diameter distal tip portion may serve as a platform for support of a stent.

  • Patent number: 5571136
    Abstract: Forceps for mounting on a substantially flexible guide wire include a first jaw defining a longitudinal lumen therethrough for mounting of the first jaw on a guide wire and for sliding longitudinal movement of the first jaw along the guide wire. A second jaw is pivotably secured to the first jaw. A flexible longitudinally-extending drive is secured to the second jaw and extends generally parallel to the guide wire. The drive is longitudinally movable between an open position wherein the jaws assume an open orientation enabling tissue to enter therebetween and a closed position wherein the jaws assume a closed orientation such that any tissue which entered intermediate the jaws in the open orientation is grasped therebetween for movement therewith.

  • Patent number: 5568863
    Abstract: A box for storing cassettes includes a base, a cover, and a plurality of side walls. One of the side walls is a spine side wall which has a window formed as an opening that permits viewing a label on the cassette. A transparent external pocket wraps around at least part of the spine side wall and at least part of either the base, the cover, or both. The transparent external pocket is the only physical barrier to prevent access to the inside of the box at the window. The external pocket permits viewing a label on the cassette and can receive a sheet of information that is readable through the transparent external pocket.

  • Patent number: 5542948
    Abstract: A surgical apparatus for simultaneously deploying a first instrument while retrieving a second instrument from the distal end of a sheath and vice versa with a single stroke actuator. The actuator includes an elongated support having a provision for grasping at one end thereof, a first sliding member having provisions for grasping and which is movable in first and second directions relative to the support, and a second sliding member operably coupled to the first sliding member such that translation of the first and second sliding members is in opposite directions relative to the support. The first sliding member is connected to the first instrument and the second sliding member is connected to the second instrument.

  • Patent number: 5458112
    Abstract: A surgical instrument assembly for use in a biopsy operation includes a flexible tube having a pair of opposed ends and a substantially rigid, cylindrical cutter having a distal end, a proximal end secured to one of the opposed tube ends for longitudinal movement therewith, and a sidewall connecting the distal and proximal ends. The cutter sidewall defines at least one recess having a barb at the outer distal end thereof for separating biopsy tissue from a patient and maintaining the separated tissue in the recess during movement of the cutter. The other of the opposed tube ends is optionally operatively securable to a vacuum source for applying a vacuum to the recess via a longitudinal cavity in the tube and cutter member.

  • Patent number: 5436604
    Abstract: A molded case for a miniature circuit breaker provides a base and a cover whose outer mating peripheral walls, which form and enclose a cavity for housing a circuit breaker mechanism, have approximately equal widths, except for the projected handle area. In this handle area, the width of the peripheral wall of the base is increased and contains an aperture for receiving the handle, and the width of the peripheral wall of the cover is decreased to receive the increased aperture area of the base. This arrangement provides for full handle support in the base for ease of assembly; high ribbing for maximum strength for short circuits; and a minimum overall thickness of about 0.500 inches.

  • Patent number: 5413095
    Abstract: This invention is directed to a mouthpiece which directs oxygen into to the mouth of a patient, whether the oxygen is supplied to the patient by a single oxygen supply tube or by conventional nasal cannulae extending from a common oxygen supply tube. In addition, the mouthpiece of the invention provides auxiliary openings through which fingers can be inserted into a patient's mouth so as to allow for manual manipulation of the mouthpiece once it is placed in the mouth.

  • Patent number: 5397302
    Abstract: A improved biliary catheter is disclosed. The catheter comprises a tube constructed from a polyurethane or nylon having a durometer of about 60D and coated with a hydrophilic coating to provide lubricity, kink resistance and suppleness. The tube has substantially cylindrical sidewalls and a proximal end for connection to a source of contrast medium and a distal end for entry into the common biliary duct of a patient. The tube contains a first crescent-shaped lumen channel extending between the proximal and the distal end, the first lumen channel transporting the contrast medium from the source of contrast medium to the biliary duct; and a second circular lumen channel extending between the proximal end and said distal end for facilitating the insertion and threading of a spring wire guide into the dual-lumen biliary catheter.

  • Patent number: 5353489
    Abstract: A device for positioning a flexible constant velocity joint boot to a shaft. A sleeve comprises a cylindrical portion enveloping the outer constant velocity joint and a conical portion receiving the drive shaft. A flexible constant velocity joint boot for enclosing the open end of the constant velocity joint is attached inside one end of an elongate cylinder. A coarsely textured strip disposed around a raised lip defined around the exterior edge of the cylinder engages the collar region of the boot and the boot and cylinder are slid over the sleeve by a handle attached to the other end of the cylinder. The boot expands over the sleeve, and hence over the outer constant velocity joint, and engages the drive shaft on the other side of the outer constant velocity joint.
