Abstract: A clip applier having a handle at a proximal portion, an elongated portion extending distally of the handle, a jaw mechanism including a pair of jaws movable to a closed position to crimp a clip held therein, a clip feeder mechanism movable in proximal and distal directions, a camming mechanism and a puller mechanism movable in proximal and distal directions. The puller mechanism is operatively connected to the handle such that actuation of the handle a) moves the puller mechanism a first distance in the proximal direction; and b) moves the clip feeder mechanism a second distance greater than the first distance.

Abstract: An instrument for applying clips in surgery particularly suited for microsurgery with instrument chassis and cover joined to form housing supporting handle and clip handling components, the handle for squeeze and release action to develop linear reciprocation motion of fixed excursion, the clip handling components for feeding a stack of clips one-by-one into instrument clip crimping jaws for application at a surgical site, an anti-backup mechanism constraining handle action to full pull and release strokes, and an instrument lock-out mechanism to prevent instrument operation after last clip in stack is used. Clip handling components of magazine carrier, magazine, clip stack, clip pusher, pusher spring, and pusher spring shaft are inserted into instrument in upwardly open channel and secured by pusher spring cover.

Abstract: A novel jaw and cam ensemble for use in a medical clip applying instrument having a compressible grip assembly at one end and a pair of squeezable jaws at the opposite end. Included is an elongated operating means connecting the cam and jaw ensemble to the compressible grips for the purpose of translating motion one to the other and for sequential advancement and closure of a plurality of clips between the jaws.

Abstract: A surgical clip applier with scissor-type operating handle and clip applying cartridge in which handle has housing of upper and lower shells that defines socket for receiving cartridge, includes a lever arm actuated linear translator for linear reciprocating movement delivered to the cartridge, and an anti-backup mechanism for full forward and release strokes of the handle, and in which cartridge includes jaws for applying clips, safety means to ensure opening of jaws for each cycle, a puller bar for receiving motion from handle and timing of jaw operation to clip feed, a magazine for feeding clips to jaws in proper sequence, and a lockout mechanism to render applier inoperative after using last clip.

Abstract: A clip applier of handle and cartridge for applying clips in surgical procedures with handle preferably a scissors type defined by a housing of shell members containing a cam operated linear translator actuated by handle levers, an anti-backup mechanism limiting handle lever movement to full pull and release strokes while preventing partial pull or release handle strokes, and with cartridge fitted with lockout mechanism to disable applier after last clip is used in surgery, with a puller bar lock to hold puller bar position in cartridge prior to assembly with handle, a detent spring mounted in cartridge cover member as part of clip handling mechanism, and a rapid-fire pawl as part of clip handling mechanism to prevent cartridge jamming when clips are applied in rapid succession.

Abstract: A clip detent spring forming part of a mechanism for inserting clips into the jaws of a clip applying instrument performs the tasks of engaging and separating a first in line clip from a line of clips carried by the mechanism, and the task of positioning the clip for insertion into the instrument jaws.

Abstract: An instrument for applying clips in surgery having an operating handle with operating components and a removable clip cartridge with clip applying mechanism. The handle operating components generate reciprocal linear motion imparted to the clip applying mechanism and accommodate rotation of the cartridge about a cartridge axis. An anti-backup mechanism constrains operating components to complete first and second strokes of reciprocal linear motion. The clip applying mechanism actuated by received reciprocal motion applies a clip in surgery, isolates the next clip, and prepares for loading the isolated clip into the jaws on a first stroke, and on the second stroke, opens the jaws and pushes the isolated clip into the open jaws.

Abstract: A repeating multi-clip applier for surgery with scissor-type or pistol grip operating handles, and a clip feeding and applying mechanism actuated by linear reciprocating movement generated by the handles. A unitary linear actuating rod and clip supply channel together with clip feed mechanisms reciprocate rearward-to-forward as the handles move for applying a clip in surgery and for advancing clips into the applying jaws.

Abstract: A surgical instrument for the deployment of medical devices such as wires and snares wherein one hand manipulates a device including advancing, opening, rotating, closing and retracting.

Abstract: A blood coagulation test system for in vitro assessment of blood characteristics including hemostasis, thrombus formation, thrombolysis, and collagen platelet interaction comprises a test unit for collection, testing and disposal of the sample together with a test analyzer for executing a test protocol. Coagulation functions are evaluated by establishing controlled bleeding of the sample from a bleeding tube within the unit and monitoring these blood characteristics as a function of blood pressure variations occurring in the unit as the test proceeds. The blood sample remains within the unit for testing and after disposal.

Abstract: A lipstick tube for one-hand operation in which a sanitary case is opened at its top end, a lipstick extended for use and then retracted, and the case closed. The tube operating components include a support frame for receiving and guiding a lipstick carrier and lipstick, closure cap for opening and closing the open top of the assembled lipstick tube, a drive mechanism for engaging and axially moving the lipstick carrier and for opening and closing the closure cap, an upper and lower exterior case members.
