Publication number: 20100222871Abstract: An improved hood provides for the attaching of endoluminal prosthesis within corporeal lumens. The hook is integrally formed with framing structure and is preset into an outward bend, but is resiliently flexible so as to form a substantially straight profile when compressed. The hook is capable of impinging upon the corporeal lumen and thereby securing the prosthesis. The hook may be configured for intraluminal delivery and deployment. A novel method of manufacturing said hook is also provided.Type: ApplicationFiled: April 30, 2010Publication date: September 2, 2010Applicant: ENDOVASCULAR TECHNOLOGIES, INC.Inventors: David T.

Publication number: 20100004726Abstract: A self-expanding, pseudo-braided device embodying a high expansion ratio and flexibility as well as comformability and improved radial force. The pseudo-braided device is particularly suited for advancement through and deployment within highly tortuous and very distal vasculature. Various forms of the pseudo-braided device are adapted for the repair of aneurysms and stenoses as well as for use in thrombectomies and embolic protection therapy.Type: ApplicationFiled: September 10, 2009Publication date: January 7, 2010Applicant: ENDOVASCULAR TECHNOLOGIES, INC.Inventors: David Hancock, Peter S.

Publication number: 20090240250Abstract: An apparatus and method for electrically induced thrombosis. The surgical device includes a first electrode and a second electrode. The first electrode is for placement adjacent to, near, or within a treatment site of a patient. The second electrode can be movable with respect to the first electrode. When the electrodes are charged by an electricity source, negatively charged blood components are attracted to the positively charged electrode while being repelled from the negatively charged electrode. Due to the electric potential between the adjacent electrodes, thrombosis is induced. The negatively charged blood and components form a thrombus or a clot adjacent to the positively charged electrode. The surgical device can be used to induce the otherwise natural process of thrombosis. When the surgical device is used in a treatment site such as a puncture or incision, the thrombosis can seal the opening created by the treatment site.Type: ApplicationFiled: October 29, 2008Publication date: September 24, 2009Applicant: ENDOVASCULAR TECHNOLOGIES, INC.Inventors: REID K. HAYASHI, MARK T. LeMERE

Publication number: 20090105805Abstract: A graft provided with a flexible sealing member to substantially prevent blood from leaking between the graft a lumen into which the graft is placed. In one embodiment, the flexible sealing member may be pressed against the vascular wall by an outwardly biased spring means attached to the sealing member. In other embodiments, the sealing member may be self-positioning upon deployment of the graft. The sealing member also may be formed into the shape of a toroid, which may be filled with thrombogenic material causing blood permeating into the toroid-shaped space to coagulate therein and hold the sealing member in place. It is also contemplated that the sealing member be formed from tufts of frayed yarn protruding circumferentially from the outer surface of the graft. A method of manufacturing such tufted yarn sealing members is also disclosed.Type: ApplicationFiled: December 19, 2008Publication date: April 23, 2009Applicant: Endovascular Technologies, Inc.Inventors: Steven G. Baker, Tamara L. Trayer, Arnold M. Escano, Mark LeMere, Elizabeth A. McDermott

Patent number: 7488345Abstract: A endovascular graft having sensing devices attached thereto to facilitate measurement of pertinent parameters within the vasculature into which the graft is implanted. Power sources and transmitters may be attached to the graft to facilitate transmission of measurements to a receiving device outside the patient's body. The sensing devices, may be electrically passive or integrated devices with measurement and transmission capability. The sensing devices may be attached to specific locations on the graft material or attached to the lumen, thereby providing pertinent parameters from critical points inside the vasculature, or may be dispersed over the surface of the graft material or within the lumen to provide a profile of pertinent parameters. The sensing devices may be attached to the graft material with one or two sutures using a running stitch to minimize graft bulk and may be coated with a material to inhibit or control tissue growth.Type: GrantFiled: January 16, 2004Date of Patent: February 10, 2009Assignee: Endovascular Technologies, Inc.Inventors: Peter S. Brown, Marcelyn A. Berlo, Tina A. Ton, Kim-Lien Dang, Veronica Creech, Joanne L. Parker

Publication number: 20090024201Abstract: An assembly for delivering a stent to an intraluminal location comprising a catheter having an inner member and an outer member, a stent positioned between the inner member and the outer member at the catheter distal end, and a cutter/slider/deployment mechanism slidable secured to the catheter proximal end. A user may vary the length of the catheter by slidably advancing the cutter/slider/deployment mechanism along the catheter, whereby excess portions of the catheter are cut away. When the desired length is achieved, the user can secure the cutter/slider/deployment mechanism to the catheter to prevent further slidable advancement. The user may also vary the configuration of the catheter handle by adding or removing a removable platform from the handle. Upon stent deployment, the stent is released from the outer member, and the stent will expand as desired.Type: ApplicationFiled: July 15, 2008Publication date: January 22, 2009Applicant: ENDOVASCULAR TECHNOLOGIES, INC.Inventors: Keif M.
