Publication number: 20210186721Abstract: In one of its aspects, the present invention relates to an endovascular prosthesis. The endovascular prosthesis includes a first expandable portion expandable from a first, unexpanded state to a second, expanded state to urge the first expandable portion against a vascular lumen and a retractable leaf portion attached to the first expandable portion. The retractable leaf portion comprises at least one spine portion and a plurality of rib portions attached to the spine portion. Longitudinally adjacent pairs of rib portions are free of interconnecting struts. The endovascular prosthesis that can be unsheathed and re-sheathed for repositioning of the endovascular prosthesis prior to final deployment thereof. There is also described a delivery device that that is particularly well suited to delivering the present endovascular prosthesis through tortuous vasculature in the body.Type: ApplicationFiled: March 8, 2021Publication date: June 24, 2021Inventors: JONATHAN G. TIPPETT, Eric Soun-Sang FUNG, Thomas R. MAROTTA, Ian T.B. MCDOUGALL, Ian M. PENN, Donald R. RICCI

Publication number: 20100223776Abstract: An expandable endovascular prosthesis comprising: body having a proximal end and a distal end; a first expandable portion disposed between the proximal end and the distal end, the tubular first expandable portion being expandable from a first, unexpanded state to a second, expanded state with a radially outward force thereon to urge the first expandable portion against a vascular lumen; and a second expandable portion attached to the first tubular expandable portion; the second expandable portion being expandable upon expansion of the tubular first expandable portion. The endovascular prosthesis is particularly useful in the treatment of aneurysms, particularly saccular aneurysms.Type: ApplicationFiled: May 17, 2010Publication date: September 9, 2010Inventors: THOMAS R. MAROTTA, DONALD R. RICCI

Publication number: 20100198250Abstract: An expandable dilation catheter advantageously useful to deliver and orient an endovascular prosthesis with respect to a target body passageway. The catheter comprises a first tubular member disposed in a proximal portion of the portion of the catheter and a second tubular member disposed in a distal portion of the catheter. The first tubular member and the second tubular member are in a spaced relationship with respect to one another. An expandable member (e.g., a balloon) is disposed distally of the second tubular member. A first lumen and a second lumen disposed in each of the first tubular member and in the second tubular member. The first lumen is in communication with an interior of the expandable member to function as an inflation lumen and the second lumen serves to receive a first guidewire. The first tubular member and second tubular member are interconnected by a coupling member.Type: ApplicationFiled: April 5, 2010Publication date: August 5, 2010Inventors: Donald R. Ricci, Thomas R. Marotta, Gyasi Bourne, Alexei Marko, Ian McDougall, Elliot Hong

Patent number: 6676696Abstract: A novel endovascular approach useful in the treatment of aneurysms, particularly saccular aneurysms. The present endovascular prosthesis comprises a leaf portion capable of being urged against and blocking the opening of the aneurysm thereby leading to obliteration of the aneurysm. The leaf portion is attached to, and independently moveable with respect to, a body comprising at least one expandable portion. Thus, the body serves the general purpose of fixing the endovascular prosthesis in place at a target body passageway in the vicinity at which the aneurysm is located and the leaf portion serves the purpose of blocking the aneurysmal opening thereby leading to obliteration of the aneurysm. A method of delivering and implanting the endovascular prosthesis is also described.Type: GrantFiled: August 1, 2001Date of Patent: January 13, 2004Inventors: Thomas R. Marotta, George A. Shukov, Donald R. Ricci, Ian M. Penn
