Patent number: 10258770Abstract: A recanalization catheter for facilitating re-entry into a lumen of a blood vessel from a subintimal space. The catheter includes an inflatable balloon mounted on a distal end region of the catheter shaft of the catheter. The catheter shaft includes a guidewire lumen having a distal opening and a lateral opening in a distal region of the catheter shaft proximal of the distal opening, and an inflation lumen in fluid communication with the balloon. The balloon is configured to be inflated in the subintimal space to a first inflation state at inflation pressures below a threshold inflation pressure to orient the lateral opening toward the lumen of the blood vessel, and inflated to a second inflation state at inflation pressures above the threshold inflation pressure. The catheter includes means for retaining the balloon in the first inflation state at pressures below the threshold inflation pressure.Type: GrantFiled: March 11, 2014Date of Patent: April 16, 2019Assignee: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Huisun Wang, Pu Zhou, Benjamin Gundale, Daniel Horn, John Chen

Patent number: 8469925Abstract: A catheter assembly may comprise a guide catheter, a balloon catheter with a steering balloon and a stabilizing balloon and a guide wire. The stabilizing balloon secures the balloon catheter to the guide catheter while the steering balloon secures the catheter assembly to the vessel wall. In another embodiment, the balloon catheter has three balloons engaged to the exterior surface, a steering balloon, a stabilizing balloon and an anchoring balloon.Type: GrantFiled: June 22, 2010Date of Patent: June 25, 2013Assignee: Boston Scientific Scimed, Inc.Inventors: Todd Rowe, David Broman, Benjamin Gundale

Publication number: 20120296364Abstract: Balloon catheter and methods for making and using balloon catheters are disclosed. An example balloon catheter may include a proximal shaft. A midshaft may be attached to the proximal shaft. The midshaft may have an outer wall. A distal shaft may be attached to the midshaft. A balloon may be coupled to the distal shaft. An inflation lumen may be defined that extends from the proximal shaft, through the midshaft, and into the distal shaft. The inflation lumen may be in fluid communication with the balloon. A support member may be attached to the outer wall of the midshaft.Type: ApplicationFiled: May 15, 2012Publication date: November 22, 2012Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: BENJAMIN GUNDALE, JEFFRY JOHNSON, CHUANJING XU

Publication number: 20120059336Abstract: An elongate shaft of a medical catheter including a thermoset polymeric tubular member including a skived distal portion. The skived distal portion includes a distally extending trough having a convex surface and a concave surface. A thermoplastic tubular sleeve may be positioned over at least a portion of the skived distal portion of the thermoset polymeric tubular member. In some instances, the thermoplastic tubular sleeve includes a crescent-shaped tubular portion defining a crescent-shaped lumen. The trough of the skived distal portion may extend through the crescent-shaped lumen. The thermoplastic tubular sleeve is thermally bonded to the inner and outer tubular members of a distal section of the elongate shaft at a guidewire port joint.Type: ApplicationFiled: November 14, 2011Publication date: March 8, 2012Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Adam D. Grovender, Benjamin Gundale, Thomas Knowles, Roger W. McGowan, Todd Rowe, Charles Rundquist, Chuanjing Xu

Patent number: 7670365Abstract: A stent delivery system which has a stent, a catheter, and a tether. The catheter has a balloon with at least one fold. The balloon and the stent both have unexpanded configurations with smaller diameters and expanded configurations with greater diameters. The tether defines a length and has a first end connected to the unexpanded stent and a contacting span enwrapped within the fold of the unexpanded balloon. The tether holds the unexpanded stent to the unexpanded balloon and releases the expanded stent from the expanded balloon.Type: GrantFiled: September 23, 2005Date of Patent: March 2, 2010Assignee: BostonScientific Scimed, Inc.Inventors: Benjamin Gundale, David Broman, Todd Rowe
