Patent number: 11026823Abstract: A control system for deploying a stent graft including a resilient ring stent at one end, provides a delivery shaft carrying the stent graft with the ring stent adjacent a proximal end of the shaft for insertion into a lumen; a retractable sleeve for containing the stent graft on the delivery shaft; a control handle adjacent the distal end, of the delivery shaft; and stent peak and valley control wires extending from the proximal end of the delivery shaft to peak and valley controllers at the control handle. Use of the control wires effects movement and/or rotation of the graft allowing fine control of deployment in the lumen.Type: GrantFiled: November 5, 2018Date of Patent: June 8, 2021Assignee: Vascutek LimitedInventors: Gary Peter McDonald, David Granville Stevenson

Patent number: 10137021Abstract: A control system for deploying a stent graft (20) including a resilient ring stent (22) at one end, provides a delivery shaft (30) carrying the stent graft with the ring stent adjacent a proximal end (33) of the shaft for insertion into a lumen; a retractable sleeve (36) for containing the stent graft on the delivery shaft; a control handle (38) adjacent the distal end (34), of the delivery shaft; and stent peak (50, 52) and valley (70, 72) control wires extending from the proximal end of the delivery shaft to peak and valley controllers (58; 74, 76) at the control handle. Use of the control wires effects movement and/or rotation of the graft allowing fine control of deployment in the lumen.Type: GrantFiled: June 1, 2012Date of Patent: November 27, 2018Assignee: VASCUTEK LIMITEDInventors: Gary Peter McDonald, David Granville Stevenson

Patent number: 9993329Abstract: A stent graft prosthesis includes spaced stent elements for location on a tubular graft. First and second stent elements are located in first and second locations on the graft. The second stent element includes a saddle shaped stent. The first stent element includes a ring shaped stent. Optionally a third stent element is also present. The tubular graft includes a graft sleeve. The prosthesis can be used for treatment of vascular disorders such as aortic aneurysm.Type: GrantFiled: June 1, 2012Date of Patent: June 12, 2018Assignee: VASCUTEK LIMITEDInventors: Gary Peter McDonald, Vincent Nelis

Patent number: 9510936Abstract: There is provided a stent element comprising a central portion with two arms extending therefrom, optionally in a V-shaped or Y-shaped configuration. The arms of the stent-element are resiliently deformable to facilitate packing and suitable material for forming the stent-element is nitinol or PEEK. The stent element can be used to stabilise two adjacent ring stents on a stent graft by attachment to the graft material between the ring stents, for example by sewing. The stent element stabilises the ring stent without risk of fracture. A stent graft having two ring stents and the stent element located between the ring stents is also described.Type: GrantFiled: June 1, 2012Date of Patent: December 6, 2016Assignee: VASCUTEK LIMITEDInventors: Gary Peter McDonald, David Granville Stevenson

Publication number: 20140121761Abstract: There is provided a stent member a plurality of spaced stent elements for location on a tubular graft, wherein a first stent element is located in a first location on said graft, and wherein a second stent element is located in a second location or said graft, and wherein the second stent element comprises a saddle shaped stent. The first stent element includes a ring shaped (circular) stent. The second stent element includes at least one, preferably 2 to 5, saddle shaped stents. Optionally a third stent element comprising from 1 to 10 saddle shaped stents is also present. The stents are typically form a continuous loop of an elongate member of resilient material such as nitinol or PEEK. A stent graft comprising a tubular sleeve to which the stent member is attached is also described, as is the use of the prosthesis for treatment of vascular disorders such as aortic aneurysm.Type: ApplicationFiled: June 1, 2012Publication date: May 1, 2014Applicant: VASCUTEK LIMITEDInventors: Gary Peter McDonald, Vincent Nelis
