Patent number: 9636115Abstract: A device for delivering an occlusive element includes an elongate sheath having a lumen therein. An elongate core member is disposed within the lumen and is formed from a proximal portion and distal portion connected via a joint. The distal portion of the elongate member includes a severable junction secured to the occlusive element. A marker coil is coaxially arranged around the distal portion of the elongate core member and is partially disposed inside the sheath lumen. A coil member is coaxially arranged around the distal portion of the elongate core member and coaxially arranged around at least a portion of the marker coil extending outside the lumen of the sheath. The coil member is secured at a distal end thereof to the distal portion of the elongate core member. The device resists axial compression while allowing for radial bending.Type: GrantFiled: June 13, 2006Date of Patent: May 2, 2017Assignees: Stryker Corporation, Stryker European Holdings I, LLCInventors: William S. Henry, Charles Daly, Russell Ford, Michael D. Williams, Hanh Duong, Hughie Devaney, Kamal Ramzipoor, Clifford Teoh, Richard Murphy, Andrew Huffmaster, Scott McGill

Publication number: 20100318171Abstract: A stent delivery system includes a delivery wire, a first stent, a second stent, and a sheath. The first stent may be disposed around a portion of a distal region of the delivery wire in a radially contracted configuration and the second stent may be disposed around a portion of the distal region of the delivery wire in a radially contracted configuration. In some cases, the first stent and the second stent may be disposed in a tandem arrangement with the first stent distal of the second stent. The sheath may be slidably disposed around the delivery wire, the first stent, and the second stent. The sheath may be retractable relative to the delivery wire to deploy the first stent and the second stent. In some embodiments, the first stent and the second stent may be sequentially deployed in an overlapping arrangement at the target site in the vessel.Type: ApplicationFiled: June 8, 2010Publication date: December 16, 2010Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Stephen Porter, William S.

Publication number: 20090105802Abstract: A self-expanding stent delivery assembly includes a shaft having a proximal end, a distal end, a distal region, a lumen, and a longitudinal axis. A retractable sheath having an outer surface, a proximal end and a distal end is co-axially disposed around the shaft distal region. A stent is disposed co-axially between the shaft and the retractable sheath. A tubular tapered tip is affixed to the retractable sheath distal end. The tubular tapered tip has an elongate region predisposed to fracturing. Methods of delivering a self-expanding stent are also described.Type: ApplicationFiled: December 17, 2008Publication date: April 23, 2009Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: William S. Henry, John E. Ortiz
