Patent number: 8562559Abstract: 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: November 12, 2010Date of Patent: October 22, 2013Assignee: Onset Medical CorporationInventors: Joseph Bishop, Jay Lenker, Edward J.

Publication number: 20120041466Abstract: 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: ApplicationFiled: May 13, 2011Publication date: February 16, 2012Applicant: ONSET MEDICAL CORPORATIONInventors: Joseph Bishop, Jay Lenker, Edward J.
