Patent number: 10369033Abstract: A delivery system that includes a catheter, a balloon, a self-expanding prosthesis, and a sheath. The sheath including an opening in a wall of the sheath that initiates rupturing of the sheath so that the self-expanding prosthesis may move from its compressed state to its expanded state. Additionally, a distal end portion of the balloon that is distal to a distal end of the sheath includes an enlarged diameter portion, the enlarged diameter portion having approximately the same outer diameter as an outer diameter of the sheath when the self-expanding prosthesis is in its compressed state, and the enlarged diameter portion being the maximum outer diameter of the balloon when the self-expanding prosthesis is in its compressed state.Type: GrantFiled: December 16, 2015Date of Patent: August 6, 2019Assignee: MERIT MEDICAL IRELAND LIMITEDInventors: Menashe Yacoby, Ascher Shmulewitz, Raz Bar-On, Gil Naor, Damian Kelly, Michael Gilmore, Mark Steckel

Publication number: 20150246210Abstract: A delivery system for a self-expandable prosthesis includes a catheter having a distal portion and a proximal portion, a balloon portion positioned on the distal portion, and a self expanding medical device positioned about the balloon portion. The medical device has a compressed state and an expanded state. A sheath couples the medical device in its compressed state about the balloon portion and has only a single opening in a wall of the sheath. When the balloon is expanded, the sheath is configured to (i) first rupture at the single opening, thereby allowing the medical device to self-expand and engage an inner wall of a vessel, and (ii) controllably continue the rupturing from the single opening to the proximal end of sheath, thereby allowing the medical device to expand to its expanded state and a portion of the medical device to engage an inner wall of the vessel.Type: ApplicationFiled: March 10, 2015Publication date: September 3, 2015Applicant: CAPPELLA, INC.Inventors: Menashe YACOBY, Ascher SHMULEWITZ, Raz BAR-ON, Gil NAOR, Damian KELLY, Michael GILMORE, Mark STECKEL

Publication number: 20090259286Abstract: A medical device delivery system includes a self-expanding medical device mounted on a balloon portion of a catheter. A sheath is provided around the medical device to hold the device in place with the device staying in a compressed state. The balloon portion is inflated to cause the sheath to rupture and release the self-expanding medical device. A number of radio-opaque markers in a pattern that will aid in determining whether or not the sheath has properly ruptured upon inflation of the balloon portion are provided on the sheath. The radio-opaque markers are positioned with respect to an expected sheath rupture propagation path along which the sheath is expected to rupture. The pattern of the markers changes as the sheath ruptures and this change is detected by an operator of the system.Type: ApplicationFiled: April 14, 2008Publication date: October 15, 2009Applicant: CAPPELLA, INC.Inventors: Rachit Ohri, Mark Steckel
