Patent number: 8920363Abstract: A hemodialysis catheter, including an elongate body with an outer wall enclosing an arterial lumen and a venous lumen, and a method of making same. The catheter includes a first continuous loop and a second continuous loop formed from a distal extension of the outer wall, the first continuous loop beginning at a first side of the distal end of the body to define a first enclosed opening, and the second continuous loop beginning at a second side of the distal end of the body to define a second enclosed opening.Type: GrantFiled: November 4, 2011Date of Patent: December 30, 2014Assignee: C. R. Bard, Inc.Inventors: Ryan C. Patterson, Kelly B. Powers, John A. Zawacki, Ryan T. Moehle, Jeff Kraus

Patent number: 8057424Abstract: A hemodialysis catheter, including an elongate body with an outer wall enclosing an arterial lumen and a venous lumen, and a method of making same. A loop extends from a distal end of the body and defines an enclosed opening. An arterial inlet in fluid communication with the arterial lumen, and a venous outlet in fluid communication with the venous lumen, are positioned on the loop.Type: GrantFiled: December 15, 2008Date of Patent: November 15, 2011Assignee: C.

Patent number: 7465286Abstract: A multi-lumen catheter comprising a loop-like structure at the distal portion of the catheter is disclosed herein. In one variation, the loop-tip catheter comprises a dual lumen catheter and a loop-like structure at the distal end of the catheter. The loop-like structure includes at least one lumen, which is in fluid communication with at lease one of the two lumens in the dual lumen catheter. One or more ports are provided on the loop-like structure for accessing the lumens within the loop. In another variation, the loop-tip catheter is configured with an arterial inlet positioned on an inner surface of the loop, while a venous outlet is positioned on an outer surface of the loop. Methods for making and using variations of the loop-tip catheter are also disclosed herein.Type: GrantFiled: March 3, 2005Date of Patent: December 16, 2008Assignee: C. R. Bard, Inc.Inventors: Ryan C.

Publication number: 20050021069Abstract: Apparatus is provided for accessing a body cavity comprising a tubular member having a deflated insertion configuration and an inflated expanded configuration that facilitates viewing within the body cavity. The apparatus is formed by everting a length of material upon itself to form a tube having a single circumference seam at the distal end, and includes an inflation tube that is sufficiently rigid to assist in inserting the tubular member into a body cavity in the deflated insertion configuration. The tubular member further includes a pattern of staggered contact areas that configured so as to avoid the creation of longitudinal features that preferentially bend when loaded, thereby ensuring that tubular member provides a substantially circular central lumen.Type: ApplicationFiled: July 23, 2004Publication date: January 27, 2005Inventors: Gerald Feuer, Michael Hogendijk, Jeff Kraus, Gerald Sanders

Patent number: 5209728Abstract: A catheter, having a substantially fluid-tight seal is provided. The seal can be used in a number of catheters, including an angioplasty catheter. The seal includes surfaces that are independently movable relative to one another. The effectiveness of the seal depends on the proximity of the surfaces, the surface are at the interface, pressure differential and viscosity of the fluid. The seal is used in connection with providing fluid-tight channels with surfaces that are relatively movable and to circumvent the need to separate hydraulic channels from other channels so that catheters can be provided with fewer channels. Further, catheters and catheter systems with smaller shaft dimensions or larger hydraulic channel dimensions is made possible. Balloon catheters using this seal have enhanced torque delivery and directional control.Type: GrantFiled: September 16, 1992Date of Patent: May 11, 1993Assignee: Danforth Biomedical, Inc.Inventors: Jeff Kraus, Robert D.
