Abstract: Devices, kits and methods for non-suture end-to-end and end-to-side anastomosis of tubular tissue members employ tubular connection members having clip retaining elements comprising annular grooves or flanges in the connection members; and spring clips which comprise a ring-shaped body with separable opposed ends whereby a circular opening defined by the body can be enlarged; the opposed ends have handling elements to facilitate handling of the clips and separation of the opposed ends; specially developed instruments facilitate use of the devices and the anastomosis procedure can be completed much more rapidly than with conventional techniques and has the significant advantage of intima to intima contact at the site of anastomosis with no foreign material exposed to the lumen of the vessels being joined.

Abstract: This invention provides a lighting source for use with a speculum. The source includes a casing having a hoop and a main portion, and a light emitter coupled to the hoop at a location diametrically opposite the main portion. An electrical energy source is contained in the main portion and the energy source is coupled to the light emitter. Switch means is provided for selectively operating the light emitter and the structure is attachable to a speculum with the light emitter positioned to illuminate the body opening when viewed through the hoop.

Abstract: The invention provides a light source for use with diagnostic devices such as laparoscope having a male fitting to receive a light tube connection for transmitting light within the device to an end for viewing using an eyepiece on the device. The light source has an elongate casing and an electrical storage battery contained in the casing. The battery extends longitudinally and has first and second poles at opposite ends of the battery. A tubular insulating insert is positioned inside the casing at one of the ends of the casing and adjacent the first of the poles. A bulb is located in the insert and has the center terminal of the bulb in electrical connection with the first pole. First and second contacts are insulated from one another and located by the insert with the first contact coupled to the body of the bulb and the second contact coupled to the second pole.

Abstract: The present invention provides a simple light which has a minimum of parts and which can be assembled simply and conveniently. The light is preferably a disposable penlight and includes a pocket clip assembly which is coupled electrically to an energy source and bulb and which has an arm movable by squeezing the arm to bring a distal end piece of the arm into contact with the housing to energize the bulb. The clip assembly includes a non-conductive fulcrum piece which is attached to the arm in engagement with the housing and intermediate the ends of the arm. This piece maintains the end piece of the clip remote from the housing to prevent accidental contact and to increase the force needed to bring the end piece into contact with the housing.

Abstract: A method for determining the relative permeability of an earth formation surrounding a wellbore having a longitudinal axis comprising the steps of injecting a fluid into the wellbore such that the fluid invades the earth formation, measuring at different points in time a quantity that varies in response to the radius from the wellbore axis of the fluid invasion into the earth formation, determining in response to said quantity measurements the radius from the wellbore axis of the fluid invasion into the earth formation, and determining in response to said radii determinations the relative permeability of the earth formation. A system for performing the method is also disclosed.
