Patent number: 8382784Abstract: A catheter-based system for accessing specific body cavities percutaneously and minimizing patient trauma is provided. In the preferred embodiment, in order to create an aperture at an access site in a patient's existing tubular body organ structure, a delivery sheath is passed axially along the interior of a portion of the existing tubular body organ structure to place a distal end of the delivery sheath near the access site. A centering wire is passed axially along the interior of the delivery sheath, piercing through from inside to outside of the patient's existing tubular body organ structure at the access site by causing an end portion of the centering wire to emerge from the distal end of the delivery sheath. A cutting catheter is passed substantially coaxially over the centering wire and axially along the interior of the delivery sheath.Type: GrantFiled: September 17, 2007Date of Patent: February 26, 2013Assignee: St. Jude Medical ATG, Inc.Inventors: Todd Allen Berg, Christopher M.

Publication number: 20020188302Abstract: A bypass graft conduit is installed in the circulatory system of a patient using apparatus which facilitates performing most or all of the necessary work intraluminally (i.e., via lumens of the patient's circulatory system). A guide structure such as a wire is installed in the patient via circulatory system lumens so that a portion of the guide structure extends along the desired path of the bypass conduit, which bypass conduit path is outside the circulatory system as it exists prior to installation of the bypass graft. The bypass graft is then introduced into the patient along the guide structure and connected at each of its ends to the circulatory system using connectors that form fluid-tight annular openings from the bypass graft lumen into the adjacent circulatory system lumens. The guide structure is then pulled out of the patient.Type: ApplicationFiled: July 23, 2002Publication date: December 12, 2002Applicant: St. Jude Medical ATG, Inc.Inventors: Todd A. Berg, Daniel J.
