Patent number: 8777979Abstract: Intravascular implant delivery systems and methods are described. One such system carries an implant by retaining an engagement member engaging the implant in a position proximal of an aperture at a distal end of the delivery system. The engagement member is retained proximal to the aperture by a cord that obstructs the movement of the engagement member through the aperture. The engagement member is free to rotate and move within an area defined by the delivery system, allowing the implant to react to forces imparted to the implant by the movement of the delivery system and implant through a delivery catheter. Once the implant is in a desired implant position, the cord is moved away from an aperture and the engagement member is allowed to move away from the delivery system.Type: GrantFiled: September 30, 2011Date of Patent: July 15, 2014Assignee: Covidien LPInventors: Sanjay Shrivastava, Earl Slee, Olivier Moret

Publication number: 20050025707Abstract: This invention is directed to compositions for embolizing vascular sites. The compositions described herein comprise fumed silica as a rheological modifier. The fumed silica imparts high viscosity to the compositions under static conditions but allows the compositions to flow readily under shear conditions. This invention is also directed to methods for treatment of aneurysms, arteriovenous fistulae, arteriovenous malformations, tumors, and other vascular diseases using the compositions described herein. Other uses are disclosed as well. Kits of parts including those compositions and devices which can deliver these composition are also described.Type: ApplicationFiled: February 26, 2004Publication date: February 3, 2005Inventors: William Patterson, Richard Greff, Meyer Rosen, Earl Slee, Thomas Whalen
