Patent number: 9931111Abstract: A suturing instrument includes a suturing head that is coupled to the shaft of an elongate body member of the instrument by a connector member which may be biased in either a linear orientation along the longitudinal axis of the shaft or any one of a variety of non-linear orientations with respect to the shaft's longitudinal axis. The connector member can comprise a resilient material such that an external force may be applied to the suturing head and move the suturing head from a biased orientation (e.g., linear) to an unbiased orientation (e.g., non-linear). Once the external force is removed, the resiliency of the connector member allows the suturing head to return from the unbiased orientation to the biased orientation. Therefore, a user may adjust the shape of the instrument by applying or removing an external force on the suturing head.Type: GrantFiled: April 25, 2014Date of Patent: April 3, 2018Assignee: Boston Scientific Scime, Inc.Inventors: Michael S. H. Chu, Robert W. Bialobrzeski

Patent number: 9352123Abstract: Embodiments of the disclosure describe an example guide extension catheter. The guide extension catheter may include a proximal shaft having a proximal end, a distal end, the distal end having an attachment region. The guide extension catheter may further include a distal sheath having a proximal end, a distal end and a lumen extending therebetween. The distal sheath may include an outer layer, inner layer and an intermediate reinforcing member disposed between the inner layer and the outer layer. Moreover, the distal sheath is attached to the attachment region adjacent to the reinforcing member.Type: GrantFiled: September 17, 2013Date of Patent: May 31, 2016Assignee: BOSTON SCIENTIFIC SCIME, INC.Inventors: Pu Zhou, Ismal Guler

Patent number: 9084609Abstract: A catheter comprises a flexible shaft having a length for accessing the renal artery. A balloon arrangement, dimensioned for deployment within the renal artery, is provided at the shaft's distal end and fluidly coupled to a lumen arrangement. A balloon body is configured to complete at least one revolution of the shaft's distal end to form a spiral configuration thereabout, and is secured to the shaft by one or more movable mounting arrangements. The balloon body supports an electrode arrangement for ablating perivascular renal nerves in a substantially spiral pattern. A cooling arrangement cools at least the electrode contact regions during ablation. The distal end of the shaft has a stiffness sufficient to oppose a force produced by the balloon body when inflated that tends to contort the shaft's distal end and to maintain a substantially constant apposition force between the electrodes and an inner wall of the renal artery.Type: GrantFiled: July 18, 2011Date of Patent: July 21, 2015Assignee: BOSTON SCIENTIFIC SCIME, INC.Inventor: Scott Smith

Patent number: 9060761Abstract: A flexible catheter includes a magnetically permeable element provided at its distal end. The magnetically permeable element is configured for placement within the renal artery. External coils, positionable on anterior and posterior portions of a patient in proximity to the renal artery, are coupled to a generator which energizes the external coils to create a high-frequency oscillating magnetic field in body tissue between the external coils including the renal artery and perivascular renal nerve tissue. The magnetically permeable element serves to concentrate the magnetic field in a region near the renal artery. The concentrated magnetic field induces high frequency electric current sufficient to ablate the perivascular renal nerve tissue proximate the renal artery. A cooling arrangement can be provided at the catheter's distal end and configured to provide cooling to the renal artery during ablation of the perivascular renal nerve tissue.Type: GrantFiled: November 9, 2011Date of Patent: June 23, 2015Assignee: BOSTON SCIENTIFIC SCIME, INC.Inventors: Roger Hastings, Scott Smith, Leonard B. Richardson, Mark L. Jenson

Patent number: 8992519Abstract: Disclosed herein, among other things, are methods and apparatus related to radio frequency (RF) ablation catheters. The present subject matter provides a method for forming an ablation catheter having a balloon at a distal end of the catheter. The method includes applying a band of conductive material to an outer surface of the balloon. The band of conductive material is adapted to provide one or more electrodes for radio frequency ablation therapy. A distal end of a lead is connected to the band of conductive material. The balloon is inverted, so that the inverted balloon includes the band of conductive material on an inside surface. According to various embodiments, the balloon includes a semi-permeable or hydro-able membrane.Type: GrantFiled: November 14, 2011Date of Patent: March 31, 2015Assignee: Boston Scientific Scime, Inc.Inventors: Isaac Kim, Josef Koblish, Robert F. Bencini

Patent number: 8973748Abstract: Medical device packaging, medical device packaging assemblies, and methods for preparing and packaging medical devices. An example medical device packaging assembly may include a packaging pouch including a front pouch portion and a back pouch portion. The front pouch portion may include a first sheet of material having a plurality of layers. The back pouch portion may include a second sheet of material having a plurality of layers. A medical device may be disposed in the pouch. At least one of the plurality of layers of first sheet of material and the plurality of layers of second sheet of material may include a moisture scavenging layer. In addition, at least one of the plurality of layers of first sheet of material and the plurality of layers of second sheet of material may include a barrier layer that is configured to maintain the oxygen concentration within the packaging pouch.Type: GrantFiled: January 19, 2012Date of Patent: March 10, 2015Assignee: Boston Scientific Scime, Inc.Inventor: Maan-Shii Wu
