Optical Fiber Connector

View page
US Patent:
50746375, Dec 24, 1991
Filed:
Jun 4, 1990
Appl. No.:
7/532884
Inventors:
Dan L. Rink - Oakland CA
Assignee:
Xintec Corporation - Oakland CA
International Classification:
G02B 638
US Classification:
385 56
Abstract:
An improved bayonet optical connector includes, in one aspect, a connector having a nut provided with at least one bayonet slot. The bayonet slot includes a detent portion to retain a bayonet pin of a mating connector, and a camming edge extends obliquely from the detent portion distally toward the mating connector. The camming edge(s) extend about a substantial portion of the nut, so that manually pushing the two connector components together causes impingement of the bayonet pin(s) on the camming edge(s), and urges the bayonet nut to rotate to bring the detent portion(s) into engagement with the pin(s). The invention also includes a nut cover secured about the bayonet nut to enhance grasping and manipulation of the bayonet nut. The bayonet nut is free of all portions of the connector except the bayonet nut, to that it acts to improve both the handling of the connector assembly and rotation and translation of the bayonet nut. Another aspect of the invention is an adapter assembly for connecting a bayonet optical connector to a threaded optical connector.

Laser Heated Intravascular Cautery Cap Assembly

View page
US Patent:
48483397, Jul 18, 1989
Filed:
Apr 11, 1988
Appl. No.:
7/179678
Inventors:
Dan Rink - Oakland CA
John Rink - San Francisco CA
Garrett Lee - Piedmont CA
Assignee:
Xintec Corporation - Oakland CA
International Classification:
A61B 1722
US Classification:
1283031
Abstract:
An improved laser heated intravascular cautery cap construction includes a generally cylindrical outersidewall, and a tappered, annular, distal end wall joining the two sidewalls and defining a closed annular space therebetween. A bore extending axially through the inner sidewall is dimentioned to receive in freely sliding fashion an arterial guidewire or other device such as a doppler flow sensor or an optical bundle for viewing. A unitary or multi-segment annular target element is received within the distal portion of the annular space, and is secured to the outer sidewall adjacent to the end wall with a gap defined between the target element and the inner sidewall. A plurality of holes extend through a connector member parallel to the axis of the sidewalls, each hole receiving therethrough one of a plurality of optical fibers extending through the arterial catheter to a laser light source. Each fiber is aimed at one segment or portion of the target element, so that the fibers may be illuminated selectively to heat the respective portion or segment and the adjacent outer sidewall and distal end wall portions. The air gap defined between the target disc segments and the inner sidewall prevents conduction to the inner sidewall.

Method And Apparatus For External Control Of Surgical Lasers

View page
US Patent:
51547074, Oct 13, 1992
Filed:
Jul 26, 1990
Appl. No.:
7/557096
Inventors:
Dan L. Rink - Oakland CA
John L. Rink - San Francisco CA
Howard S. Cohen - Berkeley CA
International Classification:
A61N 506
US Classification:
606 12
Abstract:
A method and apparatus used in combination with an existing laser for controlling the temperature of a laser powered tool includes a temperature control device coupled between the output of the laser and the optical fiber delivery system to monitor the temperature of the optical fiber delivery system and attenuate the laser output power to achieve a desired temperature level. The device establishes a beam path and provides a beam deflector that is variably positioned in the beam path to deflect a variable portion of the laser beam toward a laser wavelength-absorbing heat sink. An infrared detector is directed to receive emissions from the laser tool, and electronic circuitry processes the signal from the infrared detector to determine the temperature in the delivery system and generate an actuator signal to position the beam deflector so that beam deflection is increased or decreased to achieve a predetermined, desirable temperature level in the delivery system. A photodetector is disposed to receive ambient light from the area near the laser operation, and a time discrimination circuit receives the photodetector signal to determine if laser radiation is escaping into the area. The system causes laser shutdown if laser light is present in the area, so that operating personnel may eliminate the use of laser safety eyewear.

Apparatus For Directing A Laser Beam Into Optical Fibers

View page
US Patent:
49252658, May 15, 1990
Filed:
Apr 11, 1988
Appl. No.:
7/180950
Inventors:
John L. Rink - San Francisco CA
Dan L. Rink - Oakland CA
Garrett Lee - Piedmont CA
Assignee:
Xintec Corporation - Oakland CA
International Classification:
G02B 632
US Classification:
350 9618
Abstract:
An apparatus for selectively directing a laser beam into a plurality of optical fibers and for selectively shifting the laser beam among the fibers includes a connector member having a plurality of passages extending longitudinally therethrough, the passages being disposed in a nominal common plane. The input end of each optical fiber extends through a respective passage, with the axes of the input ends spaced closely together and oriented parallel to the axis of a laser beam directed toward the input ends. The laser beam passes through a positive lens having a focal plane coincident with the input ends of the optical fibers. An axially translatable shaft extends generally perpendicular to the nominal plane and to the beam axis, and is coupled to drive means to shift the axial position of the shaft selectively, rapidly, and reiteratively. A plurality of transparent, planar refracting panels are secured to the shaft in close axial spacing, the refracting panels oriented at differing tangential angles with respect to the shaft and disposed to be translated through the beam axis as the shaft translates to refract the laser beam parallel to the beam axis and offset therefrom sufficiently to direct the beam into an input end of a selected optical fiber.

Laser Heated Cautery Cap With Transparent Substrate

Abstract:
A laser heated cautery cap assembly includes a catheter assembly adapted to be introduced into a lumen, such as an arterial opening. The catheter assembly includes at least one optical fiber connected to a laser light source adapted to produce short output bursts. A cautery cap at the catheter distal end includes a transparent substrate member disposed to receive the laser energy from the optical fiber(s). The substrate member preferably is formed of a crystalline solid having a smooth, curved outer surface, with a central guidewire bore extending therethrough. One end of the bore is provided with a tapering counterbore, and the opposite end of the substrate member is an input surface disposed to receive laser energy from the optical fiber. A nose piece includes a central guidewire bore coaxial with the substrate member bore, the nose piece including a tapered proximal end dimensioned to fit within the counterbore of the substrate. The substrate counterbore and bore surfaces, and major portions of the curved outer surface are coated with a highly reflective material, and another portion of the outer surface is coated with a material which absorbs the laser energy and is heated thereby.

Appl. No.:
7/584921
Inventors:
Dan L. Rink - Oakland CA
Assignee:
Xintec Corporation - Oakland CA
International Classification:
G02B 638
H01R 450
F16L 2500
US Classification:
350 9621
Abstract:
An improved bayonet connector assembly includes a connector nut having a generally cylindrical tubular configuration with a bore extending axially therethrough. In one embodiment the inner surface of the bore includes at least one camming surface extending both circumferentially and axially therein and disposed to impinge upon the corresponding bayonet pin of the mating bayonet connector. A detent window is formed at the inner end of each camming surface to engage and retain the bayonet pin that is driven slidably along the camming surface into the detent window. The end surfaces of the cylindrical nut are annular and continuous, so that the strength of the structure is maximized. Furthermore, the camming surfaces and the detent slots are arranged so that the entire nut may be formed in a single molding operation. In another embodiment, the camming surfaces and detent recesses are formed on the exterior of the female connector, and the bayonet pins extend radially inwardly in the bore of the bayonet nut.
