Patent number: 7686816Abstract: The system (2) includes a catheter drive unit (22) and a catheter (24) extending therefrom movably mounted to a catheter drive sled (26). The catheter drive unit rotates and translates the catheter core (34) within the catheter sheath (36). The sled has a serrated, conical drive unit interface (82), with a bag-piercing tip (86) mateable with a translator drive output (92) so that a sterile drape (112) enclosing the catheter drive unit is automatically pierced when the catheter drive unit is mounted to the sled. A control unit (6) is spaced apart from the catheter drive unit and provides power and commands to the catheter drive unit and receives information and data from the catheter drive unit. The rotator and translator drive motors (54, 90) are operated from both the control unit and the catheter drive unit. Both the control unit and catheter drive unit have translation displacement displays (10, 30).Type: GrantFiled: October 18, 2005Date of Patent: March 30, 2010Assignee: Boston Scientific Scimed, Inc.Inventors: W.

Patent number: 5957941Abstract: A system (2) includes broadly a catheter assembly (6) and a drive assembly (4). The catheter assembly includes a hollow sheath (20) housing a connecting element, typically a drive cable (22), with an operative element, such as a transducer (24), towards its distal end (26). The drive assembly is adapted to move the connecting element longitudinally within the hollow sheath. The drive assembly includes a main body (8) to which a proximal assembly, such as a rotary drive assembly (16), connected to the proximal end (28) of the connecting element, is mounted for longitudinal movement along the main body. The main body also has an anchor element (32) which is used to secure the sheath to the main body. A longitudinal drive motor (40) is carried by the main body and drives the proximal assembly along the main body.Type: GrantFiled: September 27, 1996Date of Patent: September 28, 1999Assignee: Boston Scientific CorporationInventor: John H.

Patent number: 5951581Abstract: Apparatus and methods for intraoperatively performing surgery to create transmural channels in tissue, for example, as in transmyocardial revascularization, are provided using apparatus including a single-use handpiece having a mechanical cutting head and means for stabilizing the cutting head in contact with the tissue. The handpiece is coupled by a disposable cable to a controller that houses a vacuum pump and mechanisms for driving the cutting head. The cutting head is adapted to cooperate with the vacuum pump to evacuate tissue severed during the channel forming process.Type: GrantFiled: February 19, 1998Date of Patent: September 14, 1999Assignee: AngioTrax, Inc.Inventors: Vahid Saadat, John H.

Patent number: 5827313Abstract: An operative element mover (22) is used as a part of an ultrasound imaging or other catheter system (2) including a hollow sheath (6) and a case (16) housing a rotary driver (10). A drive cable or other connecting member (8) is disposed within the sheath with a transducer (24) at its distal end (26) and its proximal end (12) coupled to the rotary driver. The rotary driver rotates the transducer about the longitudinal axis (14) of the sheath. A hemostasis valve (50) anchors the sheath to the patient where the sheath enters the patient. The transducer mover (22) is used to move the drive cable along the longitudinal axis and includes a body (38) fixedly mountable to and dismountable from the case and a movable anchor post (40). The anchor post is clipped to the sheath and is moved by a sheath anchor drive (46) to translate the sheath from or toward the case. This causes the transducer to move within the sheath in a proximal or distal longitudinal direction (52).Type: GrantFiled: September 27, 1996Date of Patent: October 27, 1998Assignee: Boston Scientific CorporationInventor: John H.
