  • Patent number: 6451034
    Abstract: A system for performing an end-to-side vascular anastomosis, including an anastomosis device, an application instrument and methods for performing a vascular anastomosis. The system is applicable for performing an anastomosis between a vascular graft and the ascending aorta in coronary artery bypass surgery, particularly in port-access CABG surgery. A first aspect of the invention includes a vascular anastomosis staple. A first configuration has two parts: an anchor member, forming the attachment with the target vessel wall and a coupling member, forming the attachment with the bypass graft vessel. The anastomosis is completed by inserting the coupling member, with the graft vessel attached, into the anchor member. A second configuration combines the functions of the anchor member and the coupling member into a one-piece anastomosis staple.

  • Patent number: 5893879
    Abstract: An apparatus for closing wide skin defects may be used with two long interdermal needles configured for insertion underneath skin close to margins of a skin defect. The skin closing apparatus may include two retaining members (70, 71) configured as a flange connecting two legs (20) and forming a U-shaped profile. Each of the legs may include either a sharp book (23) or a blunt skin insertion element at the end of the leg adapted for percing the skin and engaging one of the long interdermal needles. Alternatively, the retaining members may include topical engagement elements for engaging portions of the interdermal needles which are located above the skin surface. A contracting mechanism such as a screw (82) may connect the retaining members and approximate the interdermal needles, while bringing the skin margins together until final closure of the skin defect results.

  • Patent number: 5830221
    Abstract: There is provided a surgical coil fastener applier for use in applying helical coil fasteners in surgical procedures, such as hernia repair, to affix surgical mesh to tissue. The coil fastener applier includes a housing having a handle extending therefrom and a trigger pivotally mounted on the housing. An elongated tubular portion extends from the housing and includes a drive rod rotatably supported therein and slidably supporting a plurality of coil fasteners thereon. A drive assembly is provided within the housing to rotate the drive rod and coil fasteners. The drive assembly includes an anti-reverse mechanism to allow rotation of the drive rod in only one direction. An actuation assembly is provided within the housing to convert the motion of the trigger into rotary motion for supply to the drive assembly. The drive assembly includes structure to limit the amount of rotary motion supplied to the drive assembly.

  • Patent number: 5829589
    Abstract: A pen needle magazine dispenser designed to be received and carried in a cap of a medication delivery pen. The dispenser having a cover rotatably mounted on a circular shaped container with a plurality of cavities, wherein each cavity is dimensioned to receive one pen needle. The pen needle being of a type that is forced fit into an adaptor on the pen using threads on the pen needle and corresponding threads in the cavity. The cover includes a slot that is rotated into alignment with one of the cavities in the container to provide the user with access to one unused pen needle and thereby permit the pen needle to be mounted on the pen. After use the used pen needle is returned to the cavity and the cover is rotated until the slot is aligned with another cavity containing the next unused pen needle to be used during the next injection.

  • Patent number: 5733265
    Abstract: A needle assembly includes an elongate needle, a needle hub with an axial bore therethrough to receive and hold the needle projecting axially, the needle hub further is releasably mountable on a fluid handling device. The assembly has an elongate shield having an open proximal end, a distal end and a sidewall with an inside surface defining a cavity. There is an elongate aperture into the cavity from about the distal end to the proximal end. The assembly has a hinge that includes a mount for retaining the shield onto the hub, the mount has an opening therein that is sized and shaped to receive at least a portion of the needle hub. The shield is movable about the hinge by an off-axis pivotal movement between an initial closed position, an open position and a latched position. The assembly has a removable cover that is disposed over the elongate aperture in the shield and engaging the shield to hold it in the initial closed position.

  • Patent number: 5672161
    Abstract: A needle assembly having a single-handedly activated needle barrier includes a needle cannula having a lumen therethrough. A needle hub having an interior cavity terminating at an open proximal end of the hub is connected to the needle cannula so that the lumen is in fluid communication with the interior cavity. A guide element having a retaining groove therethrough is connected to the needle hub. An elongate barrier arm having a proximal end and a distal end includes a barrier element at its distal end. The barrier element includes a proximal end and a needle passageway therethrough. The barrier arm is positioned within the groove of the guide element and the needle cannula is positioned at least partially within the barrier element.
