  • Publication number: 20020188247
    Abstract: An implant retention trocar includes a cannula for puncturing the skin of an animal and an obturator for delivering the implant beneath the skin of the animal. The implant retention trocar has a cannula distal tip design which causes a minimum of trauma and tearing of tissue during implant insertion. A spring element received within the cannula prevents an implant which is to be inserted into an animal from falling out of the cannula during the implant insertion process. The spring element includes a longitudinal leg which is folded with a zig-zag shaped bend. When the spring element is inserted into the cannula the zig-zag shaped bend of the longitudinal leg retains the implant within the cannula.

  • Patent number: 5522797
    Abstract: A slide action veterinary implanter apparatus includes a tubular housing having a hand grip extending therefrom with a trigger assembly pivotally mounted in the hand grip. A slide member is slidably mounted on the housing and retracts an impeller member to a retracted position, extends the trigger to an armed position, and advances a pellet magazine, extending through the hand grip, by reciprocation of the slide member. Additionally, a latch mechanism engaged with the slide mechanism, the trigger, and the impeller causes an impeller extending force to be stored and retained in an impeller extender spring as the slide member is reciprocated. Pivoting the trigger into the hand grip toward a release position releases the latch mechanism, whereby the extender spring force resiliently urges the impeller through a pellet magazine chamber driving a stack of pellets therefrom and through a needle mounted on the front end of the implanter housing.

  • Patent number: 4990136
    Abstract: A suppository applicator for inserting suppositories into body cavities comprises a tubular body having an open end and a closed end. A plunger is slidably disposed in the tubular body for reciprocal movement between a withdrawn position and an extended position and a combined spring is situated between the plunger and the closed end of the applicator to urge the plunger toward its extended position. The tubular body is formed with a longitudinal slot along its side which has a notch that extends from the slot to engage a latch on the plunger and hold the plunger in its withdrawn position. The open end of the tubular body is shaped to stationarily hold a suppository against the withdrawn plunger until the suppository is to be inserted into the body cavity. When the latch is released, the spring pushes the plunger against the suppository to insert the suppository into its desired placement in the body cavity.

  • Patent number: 4894052
    Abstract: A flash cavity is positioned between the inside of a translucent over the needle catheter and a needle for providing flash detection. The needle bore is connected to the cavity by an access port positioned near the location where the tip of the catheter sealably engages the needle. The needle bore is flow restricted between the access port and a hub for manipulating the needle. In one form of the introducer, a guide wire positioned by a syringe plunger carried for movement in a syringe barrel, is used to advance the catheter into the vessel. The syringe barrel restricts passage of liquid blood, but vents gases. In another arrangement of the introducer, a porous vent plug cooperates with the end of the needle and the catheter adapter to restrict blood flow through the needle bore and to prevent escape of blood while permitting escape of gases.

  • Patent number: 4762515
    Abstract: In pistol grip medicament implanter devices, wherein a trigger coupled to a plunger causes plunger advance movement that expels the medicament from the device when the trigger is pulled, a spring that forms part of the coupling and a lost motion arrangement controlled by the spring that converts trigger pull movement into spring take-up of the trigger movement when the plunger encounters resistance to advance movement greater than the spring bias. The trigger continues to move but the plunger does not, then when resistance to movement of the plunger becomes less than the spring bias, the spring force serves to advance the plunger, recovering the trigger pull motion previously lost.The greatest force that can be applied by the plunger to the medicament implant has become whatever bias is selected for the spring.
