Patent number: 11426196Abstract: An illuminated needle device for performing a heart valve repair includes an outer member and an inner member. The outer member includes a body that has a proximal end and a distal end. The body of the outer member defines a lumen therethrough and the distal end of the body includes a needle. The inner member is slidably disposed within the lumen of the outer member. The inner member includes a distal end that has a radiation emitting element. The illuminated needle device is characterized by the outer and inner members together forming a flexible, elongate shaft, and the inner member being configured to emit radiation from the radiation emitting element from a location proximate to the distal end of the outer member.Type: GrantFiled: December 16, 2016Date of Patent: August 30, 2022Assignee: BOSTON SCIENTIFIC SCIMED, INC.Inventors: James P. Rohl, Craig M. Wilson, Benn Horrisberger, Carl W. Bauer, Lance A. Freeseman

Publication number: 20220096794Abstract: Tissue puncture devices, and systems and methods for accessing tissue (e.g., cardiovascular tissue) according to the present disclosure may include a tubular sheath extending along a longitudinal axis, the tubular sheath having a proximal end and a distal end, a needle disposed coaxially in the sheath, the needle having a proximal end and a distal end and being movable along the longitudinal axis of sheath, and a needle control mechanism disposed at the proximal end of the needle, the needle control mechanism being configured to lock the distal end of the needle in a first position retracted within the distal end of the sheath, and release the needle to an unlocked second position such that the distal end of the needle is extendable beyond the distal end of the sheath.Type: ApplicationFiled: December 8, 2021Publication date: March 31, 2022Inventors: Lance A. Freeseman, James P. Rohl, Joel T. Eggert, Eric M. Petersen, Craig M. Wilson, Douglas D. Pagoria, Todd College

Patent number: 11020228Abstract: Anchor delivery systems and methods for repairing a valve inside a body, such as a heart valve, may include a delivery catheter having a distal end comprised of two or more rotatably coupled knuckles. An anchor delivery mechanism is disposed distally of the two or more knuckles, and includes a first pincer arm having a distal end and a proximal end rotatably coupled to a distal end of the anchor delivery mechanism at a first connection point, and a second pincer arm having a distal end and a proximal end rotatably coupled to the distal end of the anchor delivery mechanism at a second connection point opposite the first connection point. In a closed position, the distal ends of the first and second pincer arms are positioned together. In an open position, the distal ends of the first and second pincer arms are rotated apart from each other.Type: GrantFiled: August 16, 2018Date of Patent: June 1, 2021Assignee: Boston Scientific Scimed, Inc.Inventors: James P. Rohl, Joel T. Eggert, Katherine L. Baldwin, Craig M. Wilson, Lance A. Freeseman, James K. Cawthra, Jr., Dennis B. Werner, Daniel Shuey, Jonathan P. Fettig, Todd College, Gurpreet S. Sandhu, Joseph A.

Publication number: 20190142246Abstract: A visualization catheter includes an elongate shaft, a cap portion, and an offset balloon coupled to the distal end of the shaft. The elongate shaft includes a proximal end, a distal end, and a central axis defined therebetween. The cap portion is coupled to the distal end of the shaft. The cap portion also includes a visualization element and defines an aperture. The offset balloon is coupled to the distal end of the shaft and encapsulates the cap portion. The offset balloon defines a center point offset relative to the central axis of the shaft.Type: ApplicationFiled: December 16, 2016Publication date: May 16, 2019Applicants: BOSTON SCIENTIFIC SCIMED, INC., MAYO FOUNDATION FOR MEDICAL EDUCATION AND RESEARCHInventors: BENN HORRISBERGER, JAMES P.
