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.

Patent number: 7699864Abstract: An access device comprises a thin-walled sheath that is insertable into a patient through a small surgically created incision. The incision may be created using a cutdown or a percutaneous method such as that known as the Seldinger technique. Once inserted and advanced to the target surgical site, the sheath is selectively, and controllably, expanded to a desired diameter. The thin wall of the sheath is fabricated from a rectangular piece of material such as metal or plastic with two cut edges. The rectangular piece of metal or plastic is rolled tightly to create the small diameter configuration that is inserted into the patient. A cam or control member is affixed to the innermost edge of the rectangular piece of metal or plastic. The control member extends to the proximal most portion of the sheath. By rotating the control member, the operator causes the thin wall piece of rolled material to unfurl into a larger or smaller diameter, depending on the direction of rotation.Type: GrantFiled: May 7, 2004Date of Patent: April 20, 2010Assignee: Onset Medical CorporationInventors: George F.

Publication number: 20060253102Abstract: A transluminal sheath is disclosed that permits instrumentation to be passed therethrough. The transluminal sheath comprises a composite structure with an inner layer, an outer layer, and a reinforcing layer. The materials comprising the inner and outer layer are plastically deformable and maintain their shape, once bent into a specific configuration. The reinforcing layer further has radiopacity enhancing coatings to improve visibility under fluoroscopy and a system of flutes running longitudinally, to enhance fluid transport and reduce friction.Type: ApplicationFiled: December 21, 2005Publication date: November 9, 2006Inventors: Edward Nance, Jay Lenker, Onnik Tchulluian

Publication number: 20060041270Abstract: An expandable sheath is insertable into a patient through an incision. Once inserted and advanced to the target surgical site, the sheath can be expanded to an enlarged diameter. The wall of the sheath is fabricated from a tubular structure comprising filamentous elements that extend axially and at least partially circumferentially along the length of the sheath. The tubular filamentous material is drawn or expanded axially to create the small diameter configuration that is inserted into the patient. A standoff attaches the distal end of the tubular filamentous material to the sheath hub by way of radially movable anchors. Additional filamentous tubular material extends out the proximal end of the hub. A compression mechanism forces the additional filamentous tubular material in the distal direction which causes axial compression and radial or diametric dilation of the working length of the sheath, that part of the sheath that extends beyond the proximal end of the hub.Type: ApplicationFiled: May 9, 2005Publication date: February 23, 2006Inventors: Jay Lenker, Onnik Tchulluian, Edward Nance
