Patent number: 9539052Abstract: An apparatus treats tissue at or near a sphincter. The apparatus has an elongated member having at least one lumen including an inflation lumen, and a basket assembly including a first and a second arm. An inflatable member is coupled to the inflation lumen and has a deployed and a non-deployed state. In the deployed state, the inflatable member expands the basket assembly into contact with tissue. At least one of the first and second arms of the basket assembly has a fluid lumen having an aperture for conveying a fluid from the basket assembly. A source of fluid is coupled to the fluid lumen for conveyance of fluid through the aperture. The fluid can be, e.g., an electrolytic solution, and/or an anti-infection agent, and/or an echogenic media, and/or a steroid, and/or an anesthetic, and/or a medicament, and/or a tissue cooling agent. The source can be a drug delivery device.Type: GrantFiled: October 25, 2014Date of Patent: January 10, 2017Assignee: Mederi Therapeutics, Inc.Inventors: Stuart D. Edwards, John W. Gaiser, David S. Utley, Jay J. Qin

Patent number: 7125407Abstract: A sphincter treatment apparatus includes an elongated member having at least one lumen including an inflation lumen and a basket assembly with first and second arms. The basket assembly is coupled to the elongated member and has deployed and non-deployed configurations. An inflatable member is coupled to the elongated member and positioned in an interior of the basket assembly. The inflatable member has deployed and non-deployed states and is coupled to the inflation lumen. In the deployed state, the inflatable member expands the basket assembly to its deployed configuration. A first energy delivery device is positionable in the first arm and advanceable from the first arm to a selected treatment site. A second energy delivery device is positionable in the second arm and advanceable from the second arm to a selected treatment site.Type: GrantFiled: December 5, 2003Date of Patent: October 24, 2006Assignee: Curon Medical, Inc.Inventors: Stuart D Edwards, John W.

Patent number: 6251092Abstract: A deflectable guiding catheter generally having an elongated shaft with a deflectable distal section, a second lumen, a first lumen in fluid communication with a port in the distal end of the shaft, an elongated tapered deflection line within the second lumen, and reinforcement strands within a wall of the shaft. The first lumen is independent from the second lumen, and is therefore not obstructed by the deflection line. The longitudinal axes of the second lumen and first lumen are axially aligned with respect to one another, and are eccentric to the shaft longitudinal axis. The reinforcement strands and the deflection line extend in at least a portion of the deflectable distal shaft section to a location spaced proximally of the distal end of the deflectable distal shaft section.Type: GrantFiled: December 30, 1997Date of Patent: June 26, 2001Assignee: Medtronic, Inc.Inventors: Jay J. Qin, Duane Dickens, Laurent Schaller

Patent number: 5807249Abstract: A reduced stiffness, bidirectionally deflecting catheter assembly (2) includes a handle (4) and flexible catheter shaft (6) with a tip section (12) secured to its distal end (14). The tip section has a radially offset, longitudinally extending core wire lumen (42) through which a tapered core wire (24), extending from a core wire manipulator (56) on the handle, passes. The core wire manipulator can be moved in two different directions (58, 60) to pull or push on the core wire to cause the tip section to deflect axially in opposite directions in the same plane. The ends of the core wire are non-rotatably secured to the handle and the tip section so that rotating the handle about its axis (63) causes the tip section to deflect laterally due to torsionally forces exerted on the tip section by both the catheter shaft and the core wire. The taper on the core wire determines the size and shape of the curved tip section when the tip is axially deflected.Type: GrantFiled: February 13, 1997Date of Patent: September 15, 1998Assignee: Medtronic, Inc.Inventors: Jay J.
