  • Patent number: 8480689
    Abstract: A surgical suturing device has a grasper device that is translatable within an outer lumen where a first end of a needle is grasped with the grasper device. The needle may be resilient to a curved resting state. The grasper device translates proximally relative to the outer lumen such that the needle is translated into the outer lumen, wherein the outer lumen tends to straighten the needle from the curved resting state. The grasper device may be translated distally relative to the outer lumen such that a second end of the needle extends distally from the outer lumen and pierces the tissue. The needle may return to the curved resting state as it exits the outer lumen. When a second end of the needle emerges from the tissue, the second end of the needle may be grasped with the grasper device.

  • Publication number: 20130158348
    Abstract: An introducer for an internal magnetic camera is provided. The introducer may be arranged to enable the camera to be placed inside of a body cavity through an otomy or incision and then oriented next to the tissue of the body cavity opposite an External Control Unit (“ECU”) outside of the body cavity. The camera may be retained in the introducer by a magnet or a magnetic material, by a selectively engageable retainer, or by covering the camera within a cavity. The camera may be retained in the introducer by a latch. The camera may include a keyed surface that only can align with a matching keyed surface on the retainer in a single orientation. The introducer may include a spring to eject the camera from the introducer when the retainer is disengaged.

  • Patent number: 8361112
    Abstract: A surgical instrument may comprise a shaft having proximal and distal ends defining an axis therebetween. The shaft may be flexible and sized for insertion into the working channel of a flexible endoscope. The shaft may be configured to be used in conjunction with various suture anchor applicators. One suture anchor applicator may have a first tube with a first channel and a tissue penetrating tip. The first channel may be adapted to retain a second tube. The second tube may have a second channel and a blunt tip. The second channel may be adapted to retain at least one suture anchor and may include an exit port adapted for ejecting suture anchors. An alternative suture anchor applicator may comprise a first tube and a second tube with a tissue penetrating tip. The second channel is adapted to retain at least one suture anchor.
