  • Patent number: 5971939
    Abstract: A needle biopsy device has a suction source, an inner cannula, and an outer cannula. The inner cannula has a biopsy reservoir formed proximate the distal end thereof and also has a lumen formed therein. The lumen provides fluid communication from the suction source to the biopsy reservoir. The outer cannula is slidably disposed about the inner cannula and has a cutter formed at the distal end thereof. The outer cannula has a distal position wherein it substantially covers the biopsy reservoir and has a proximate position wherein the biopsy reservoir is substantially exposed. An actuating mechanism moves the outer cannula from the distal position to the proximate position thereof, facilitates the application of suction from the suction source to the biopsy reservoir and moves the outer cannula from the proximate position to the distal position thereof.

  • Patent number: 5741277
    Abstract: A method and device for the placement of sutures and for the purpose of approximating tissue. A particular utility is effected in the approximation of the tissue separated by means of an endosurgical trocar being inserted into a body cavity. The invention provides for the loading of suture material including needles into the device, introduction and placement of the device into the body cavity, with the distal end having deployable needle guides, extending the needle guides either simultaneously or individually to the periphery of the wound, engaging the wound with the needle guides, driving the needles and suture material through the tissue to be approximated into a catch mechanism, retracting the needle guides and withdrawing the device, leaving a loop of suture material in the margin of tissue. The suture may then be tied to approximate the wound and excess suture material cut off.

  • Patent number: 5662664
    Abstract: A suturing device includes a shouldered surgical needle where the shoulder has a cross sectional transverse dimension. A suture is attached to a distal portion of the needle. A needle catch having a flexible aperture with a relaxed dimension which is smaller than the cross sectional transverse dimension of the shoulder allows insertion of the needle into the flexible aperture by expansion of the flexible aperture to a stretched dimension which is substantially equal to the cross sectional transverse dimension of the shoulder. The shoulder on the needle prevents removal of the needle from the flexible aperture in a direction which is the reverse of its direction of insertion into the flexible aperture.
