Patent number: 8308781Abstract: A cranial bolt secured to a skull of a patient includes a threaded portion and a lumen portion. Threaded portion has an inner surface forming a central passageway which extends throughout the threaded portion. The inner surface includes a connector mating with the lumen portion. The lumen portion includes a stem portion that enters the central passageway and engages the mating connector. A fluid tight seal is formed between the inner surface of the threaded portion and the stem portion. At least two lumens are disposed through the stem portion and the base portion. The lumens have a proximal end opening outside the skull and a distal end opening inside the skull. One embodiment includes sensor lumens diverging from the centerline and another allows the lumen portion to rotate independent of the threaded portion.Type: GrantFiled: September 9, 2009Date of Patent: November 13, 2012Assignee: Codman & Shurtleff, Inc.Inventors: Stephen F.

Publication number: 20110213383Abstract: A medical system and surgical instrument adapter are provided. The medical system comprises a surgical instrument carrying a distal tool configured for performing a medical procedure on a patient, an adapter having a clam-shell configuration configured for removably receiving a proximal end of the surgical instrument, and a drive unit configured for being coupled to the adapter to control the movement of the surgical instrument within at least one degree-of-freedom. The surgical instrument adapter may comprise a base portion configured for receiving a proximal end of the surgical instrument, and a clam-shell that pivots relative to the base portion between a first position that encloses the proximal end of the surgical instrument within the base portion and a second position that allows the proximal end of the surgical instrument to be removed from the base portion.Type: ApplicationFiled: May 12, 2011Publication date: September 1, 2011Applicant: HANSEN MEDICAL, INC.Inventors: Woojin Lee, Michael J.

Patent number: 6363273Abstract: The present invention provides an introducer element for facilitating the insertion of a medical instrument into a body. The introducer element includes first, second, third and fourth housing areas. The first area contains a first lumen and the second area contains a second lumen. A quantity of peel-away tubing is partially disposed within the second lumen. The first and second lumen are separated from each other in the first and second housing areas, but are merged into one lumen in either the third or fourth housing area by a guide/splitting tube.Type: GrantFiled: December 22, 1999Date of Patent: March 26, 2002Assignee: Codman & Shurtleff, Inc.Inventors: Brooke W. Mastrorio, Michael C. Gorhan, Timothy A. Beardsley
