  • Patent number: 9011461
    Abstract: A surgical instrument configured to perform circumcision includes a hollow body having each of an anterior open end and an axially opposed posterior open end. A dome shaped member is attached in a detachable manner to the anterior end of the hollow body and has a generally semispherical shape. One or more apertures are formed through a wall of the dome shaped member and are sized to pass urine therethrough. An elongated handle is centered on the longitudinal axis and has a portion thereof positioned adjacent a juncture with one of the anterior end of the hollow body and the apex of the dome shaped member being weaker than any other portion of the body or the generally dome shaped member, whereby a reciprocation of the elongated handle causes the elongated handle to fracture at the juncture and become detached from the hollow body or the generally dome shaped member.

  • Patent number: 8808348
    Abstract: A drainage stent delivery system including an elongate shaft of a medial device, a drainage catheter or stent, and an interference fit member for selectively coupling the drainage stent to the elongate shaft. The drainage stent is selectively coupled to a distal portion of the elongate shaft by an interference fit between the interference fit member and the drainage stent such that axial movement of the elongate shaft relative to the drainage stent moves the interference fit member from a first position in which the interference fit member is engaged with the drainage stent and forms an interference fit with the drainage stent to a second position in which the interference fit member is disengaged from the drainage stent.

  • Patent number: 8007508
    Abstract: A system for tissue dissection and retraction is disclosed herein. A tissue dissection assembly generally comprises an elongate body shaft, an actuation member movable relative to the elongate body shaft, and at least one dissector arm member having at least a first end attached to the elongate body shaft, wherein the at least one dissector arm member is adapted to reconfigure within a plane from a low profile to an expanded profile when urged via the actuation member, and wherein the at least one dissector arm is further adapted to dissect tissue within the plane. In use, the assembly dissects tissue within the plane typically by advancing the elongate body shaft into the tissue region where the dissector arm member or members are then reconfigured within the plane from its low profile to its expanded profile to thereby dissect the tissue region along the plane.
