Publication number: 20150164542Abstract: An interventional catheter assembly has an operating head and catheter system that are inserted and navigated within a patient's body while an operator controls the system externally of the operating head. An operating head is positioned at or near a distal end of the catheter system and coupled to a drive shaft and drive system for rotation. A guidewire brake control system interrupt prevents the drive system from being actuated when the guidewire brake is in a released position, and a selectable guidewire brake interrupt override control permits an operator to translate and/or rotate the drive shaft and operating head while the guidewire is simultaneously moved. This allows withdrawal of the guide wire and the operating head from the target site while rotating the operating head.Type: ApplicationFiled: February 10, 2015Publication date: June 18, 2015Applicant: BOSTON SCIENTIFIC LIMITEDInventors: EDWARD I. WULFMAN, CASEY TORRANCE, BRIAN CRAN, SCOTT YOUMANS

Patent number: 8475484Abstract: A sealing assembly hinders or prevents air or other fluid from seeping between various components of a medical device by use of a liquid seal. An infusion port is for introducing a sealing liquid to immerse a flood space between a liner that surrounds a torque tube and/or within the torque tube, thereby creating a liquid seal around the torque tube and lubricating the torque tube. The length of the liner and the cross sectional space of the flood space are adjusted to control flow rate. An aspiration port may force suction pressure into a lumen extending along the length of the medical device in a distal direction. The liquid seal also prevents diluting of the suction pressure by stopping ingress of air.Type: GrantFiled: March 10, 2004Date of Patent: July 2, 2013Assignee: MEDRAD, Inc.Inventors: Edward I. Wulfman, Casey Torrance

Patent number: 8435228Abstract: Interventional catheter assemblies that operate over a guide wire and incorporate guide wire management systems are disclosed. Specifically, a guide wire buffer zone is provided between a proximal end of the interventional catheter and the guide wire clamp that accommodates variable lengths of exposed guide wire in an unrestrained condition when the guide wire is clamped, allowing the distal end of the operating catheter to be advanced and retracted over the distal end of the guide wire without repositioning and reclamping the proximal end of the guide wire. The configuration of the guide wire buffer zone may be adjusted prior to or during an intervention based on the anticipated range of axial motion of the catheter and operating head relative to the guide wire.Type: GrantFiled: August 11, 2010Date of Patent: May 7, 2013Assignee: MEDRAD, Inc.Inventors: Edward I.

Patent number: 8394078Abstract: An interventional catheter assembly comprises an operating head for removing obstructive material from a target site in a body lumen or cavity and at least one aspiration port located proximal to the operating head and penetrating the catheter assembly, the aspiration port being in communication with a sealed lumen that communicates with a vacuum system for withdrawing aspirate fluid and obstructive material from the target site. The interventional catheter incorporates an elongated guidewire lumen bushing extending proximally from a distal region of the operating head to reduce the clearance between the guidewire and the internal surface of the guidewire lumen during operation of the interventional catheter. This feature restricts entry of fluid and debris into the guidewire lumen and promotes maintenance of consistent and high aspiration pressure and volume during operation of the aspiration system and interventional catheter assembly.Type: GrantFiled: May 7, 2010Date of Patent: March 12, 2013Assignee: MEDRAD, Inc.Inventors: Casey Torrance, Jared Salstrom

Patent number: 7674272Abstract: A bearing system useful in an intracorporeal device connects an operating head, a rotatable drive shaft and a catheter. The bearing system includes a static member in fixed communication with the distal end of the catheter, an interior shaft that is in rotatable communication with the drive shaft and the operating head, and at least one connecting structure. The static member has at least one opening through which the connecting structure moveably rests against a seat of the interior shaft. The position of the connecting structure within the seat enables the bearing to accept a rotational load of the rotating drive shaft and/or thrust load in the direction of the longitudinal length of the catheter. The connecting structure further retains the internal shaft and static member of the bearing system.Type: GrantFiled: January 20, 2004Date of Patent: March 9, 2010Assignee: Pathway Medical Technologies, Inc.Inventors: Casey Torrance, Edward I.
