Patent number: 10272231Abstract: Disclosed is an expandable transluminal sheath, for introduction into the body while in a first, low cross-sectional area configuration, and subsequent expansion of at least a part of the distal end of the sheath to a second, enlarged cross-sectional configuration. The sheath is configured for use in the vascular system. The access route is through the inferior vena cava to the right atrium, where a trans-septal puncture, followed by advancement of the catheter is completed. The distal end of the sheath is maintained in the first, low cross-sectional configuration during advancement through the atrial septum into the left atrium. The distal end of the sheath is expanded using a radial dilator. In one application, the sheath is utilized to provide access for a diagnostic or therapeutic procedure such as electrophysiological mapping of the heart, radio-frequency ablation of left atrial tissue, placement of atrial implants, valve repair, or the like.Type: GrantFiled: October 11, 2013Date of Patent: April 30, 2019Assignee: Onset Medical CorporationInventors: George F. Kick, Jay A. Lenker, Edward J. Nance, Joseph Bishop, Onnik Tchulluian, Huan T. Nguyen

Patent number: 9440054Abstract: Disclosed is an expandable transluminal sheath, for introduction into the body while in a first, small cross-sectional area configuration, and subsequent expansion of at least a part of the distal end of the sheath to a second, enlarged cross-sectional configuration. The sheath is configured for use in the vascular system and has utility in the introduction and removal of implant delivery catheters. The access route is through the ventricular myocardium, more specifically at the left ventricular apex, into the aortic root. The distal end of the sheath is maintained in the first, low cross-sectional configuration during advancement to the arteries into the aorta. The distal end of the sheath is subsequently expanded using a radial dilatation device, which is removed prior to the introduction of implant delivery catheters. In an exemplary application, the sheath includes a supported proximal end, a supported distal end, and a collapsible center section.Type: GrantFiled: October 24, 2008Date of Patent: September 13, 2016Assignee: Onset Medical CorporationInventors: Joseph Bishop, Jay Lenker, Edward J.

Patent number: 9387314Abstract: Disclosed is an expandable transluminal sheath, for introduction into the body while in a first, collapsed cross-sectional configuration, subsequent expansion of at least a part of the distal end of the sheath to a second, enlarged cross-sectional configuration, and subsequent removal in a third, collapsed cross-sectional configuration. The sheath is configured for use in the vascular system and has utility in the introduction and removal of implant delivery catheters. The access route is through the femoral arteries and the iliac arteries into the aorta. The distal end of the sheath is maintained in the first, collapsed cross-sectional configuration during advancement to the arteries into the aorta. The distal end of the sheath is then expanded using a radial dilatation device, which is removed prior to the introduction of implant delivery catheters. The distal end of the sheath is subsequently reduced to a diametrically small size for removal.Type: GrantFiled: September 18, 2013Date of Patent: July 12, 2016Assignee: Onset Medical CorporationInventors: Joseph Bishop, Jay A.

Patent number: 9044577Abstract: Disclosed is an expandable percutaneous sheath, for introduction into the body while in a first, low cross-sectional area configuration, and subsequent expansion to a second, enlarged cross-sectional configuration. The sheath is maintained in the first, low cross-sectional configuration by a removable tubular restraint or by structural elements built into the wall of the expandable portion of the sheath. In one application, the sheath is utilized to introduce a formed in place orthopedic fixation rod such as for use in spinal fixation procedures, preparation of a spinal segment, or placement of a vertebral body spacer. The sheath can further comprise structural elements to permit re-collapse of the sheath under fluid pressure following completion of the procedure and prior to removal from the patient.Type: GrantFiled: May 13, 2011Date of Patent: June 2, 2015Assignee: Onset Medical CorporationInventors: Joseph Bishop, Jay Lenker, Edward J.
