  • Apparatus and method of maintaining insufflation
    Patent number: 8419695
    Abstract: An apparatus includes a body configured to be at least partially inserted into a rectum of a patient. The body defines a first passageway and a second passageway between a proximal end portion and a distal end portion. The first passageway is configured to receive a medical tool and the second passageway is configured to communicate an insufflation medium. An insufflation port is coupled to the second passageway and is configured to communicate the insufflation medium to the second passageway.

  • THROMBUS FILTER WITH BREAK-AWAY ANCHOR MEMBERS
    Publication number: 20130023921
    Abstract: A thrombus filter which can be securely fixed at a selected location in the vascular system of a patient and removed when no longer required. The thrombus filter includes a body portion and a plurality of struts, each strut having a joined end and a free end. The joined end of each strut is fixably attached to the body portion. The struts radiate outwardly from the body member such that the thrombus filter is generally conical in shape. The free end of each strut includes an anchor member. A weakened portion is disposed proximate the free end of each strut. When removal of the thrombus filter is desired, forces are applied to the thrombus filter causing the struts to break at the weakened portions proximate the free ends.

  • KNOTLESS SUTURE ANCHOR WITH UNTHREADED NOSE
    Publication number: 20120053629
    Abstract: A suture anchor has a tubular body having an axial bore therethrough with one or more purchase enhancements on an exterior surface of the body adapted to enhance purchase of the body within a bone hole. These are preferably screw threads. A distal nose of the suture body has a smooth exterior surface. A length of suture passes down along the exterior surface over the purchase enhancements, over the distal nose, and up into the bore. The smooth exterior surface of the distal nose allows tension of the suture to be held by the engagement of the nose within the bone hole thus making it easier to obtain proper tension as the remaining portion is engaged into the bone hole to provide final fixation.
