  • Publication number: 20140323855
    Abstract: A medical device for reducing the force necessary to penetrate living being tissue using a variety of reciprocating motion actuators, including piezoelectric, voice coil, solenoids, pneumatics or fluidics. The reciprocating actuator drives a penetrating member through the tissue at a reduced force while the device detects the passage of the penetrating member through the tissue. Upon passage of the penetrating member through the tissue, electrical power to the reciprocating actuator is automatically terminated. A fluid-containing syringe may be coupled to a channel within the penetrating member. Once the penetrating member tip has passed through the living tissue, the fluid within the syringe no longer experiences any pressure and a plunger within the syringe displaces indicating passage of the penetrating member tip. This motion can provide direct tactile feedback to an operator of the medical device or can automatically open a switch providing electrical power to the medical device.

  • Patent number: 7329242
    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 zigzag-shaped bend. When the spring element is inserted into the cannula, the zigzag-shaped bend of the longitudinal leg retains the implant within the cannula.

  • Patent number: 7320683
    Abstract: A syringe assembly including a needle cannula having a five-beveled point and a needle shield formed of a styrene block poly(ethylene/butylene) thermoplastic elastomer which significantly reduces needle penetration force and may reduce the cycle time for gas sterilization. The multi-beveled needle cannula point includes a primary bevel, a pair of tip bevels and a pair of middle bevels each intermediate the primary bevel and a respective tip bevel, wherein the angles of rotation of the primary bevel and the intermediate bevels are substantially equal resulting in reduced heights of intercepts between the bevels, therby reducing needle penetration force. The needle shield maintains the sharpness of the needle cannula during application, sterilization and removal of the shield and it is believed that the needle shield will also reduce the cycle time of gas sterilization as compared to rubber needle shields and vulcanizate thermoplastic elastomers.

  • Patent number: 7022110
    Abstract: A medical needle includes a solid rod-like inner needle to be inserted into the living tissue, and a hollow cylindrical outer tube needle to be inserted into the living tissue together with the inner needle, while the inner needle is inserted into the inner needle. The hollow cylindrical outer tube needle is retained in the living tissue after the inner needle is removed. A tip portion of the inner needle extending out of a front end bore of the outer tube needle is formed as a spherical crown portion capable of being inserted along a punctured hole previously formed in the living tissue so as not to damage the lumen of the punctured hole. Accordingly, it is possible to reduce a pain upon creating a puncture, subcutaneous bleeding and damage to a blood vessel wall, eliminate coring, and an infectious accident.
