Patent number: 6280448Abstract: A system for inserting a cannulated tissue anchor during endoscopic surgical procedures. The system incorporates an elongated generally cylindrical tissue anchor having a plurality of barbs outwardly extending from its body and a transverse head situated at its proximal end. The head is elongated along a major axis which is misaligned relative to the rows of barbs on the body of the tissue anchor in order to enhance retention of the anchor within selected tissue. The anchor may be inserted during an endoscopic surgical procedure by a single-handed operation utilizing an instrument having a longitudinally slidable needle for guiding the anchor into place and a longitudinally slidable push rod for pushing the anchor along the needle. The system incorporates a package/loading device to facilitate the assembly of a cannulated tissue anchor with the inserter, the package/loading device being provided with a means for guiding the inserter needle through the axial bore of the tissue anchor.Type: GrantFiled: June 9, 2000Date of Patent: August 28, 2001Assignee: Linvatec CorporationInventors: A.

Patent number: 6074395Abstract: A system for inserting a cannulated tissue anchor during endoscopic or other surgical procedures. The system incorporates an insertion instrument for inserting into a surgical site of implantation an elongated generally cylindrical tissue anchor having, for example, a plurality of barbs outwardly extending from its body and a transverse head situated at its proximal end. The anchor may be inserted by a single-handed operation of the instrument through a series of sequential pulls of a trigger, each pull affecting motion of a particular element. In a preferred embodiment, three trigger pulls are sufficient to penetrate the site of implantation and deliver the anchor slidably along the needle. The instrument operates with replaceable subassemblies each containing a particular size cannulated anchor, having a longitudinally slidable needle for guiding the anchor into place and a longitudinally slidable push rod for pushing the anchor along the needle.Type: GrantFiled: February 2, 1999Date of Patent: June 13, 2000Assignee: Linvatec CorporationInventors: A.

Patent number: 4796624Abstract: An apparatus is disclosed for introducing a liquid within a material. The apparatus comprises a body member having an internal cavity for receiving a battery. An end member is secured to the body member for supporting a needle guide extending through the end member for slidably receiving a needle. A reciprocal coupling means interconnects the motor and the needle for reciprocating the needle relative to the end member upon rotation of the motor. A reservoir is in fluid communication with the needle for retaining the liquid therein and for enabling the liquid to flow along the needle. The reciprocating needle creates a plurality of perforations in the material enabling the liquid to flow along the needle to enter the perforations. The apparatus is suitable for introducing a liquid pigment into a skin tissue such as introducing a permanent eyeliner into an eyelid.Type: GrantFiled: November 19, 1986Date of Patent: January 10, 1989Assignee: Concept, Inc.Inventors: Arthur F.
