Patent ID: 7235094

Claim:
A delivery system for release of a prosthesis having anchoring stents, comprising: a pair of releasing balloon catheters each having: an inflatable balloon adapted to be inserted within a corresponding stent of the prosthesis and to continue adhering thereto throughout a time prior to release thereof; a self-supporting tube defining a single lumen and having a first diameter and two opposing ends; a cup connection having a second diameter greater than said first diameter, said cup connection being disposed at a first of said ends, fluidically connecting said lumen with said inflatable balloon, and connecting said inflatable balloon to said tube for passing liquid to inflate said inflatable balloon; and a terminal connection fluidically connected to said lumen at a second of said ends; a pair of inflating syringes each having a connection for releasable attachment to said terminal connection of a respective one of said releasing catheters and for fluidically connecting a respective one of said syringes to said inflatable balloon to inflate said inflatable balloon and thereby release a respective stent; a pair of guiding balloon catheters each having: a dilator defining an inner lumen having an inner third diameter sized to pass said tube of said releasing catheter therethrough, said dilator having: a proximal portion having an outer fourth diameter larger than said inner third diameter and being fitted with a haemostatic valve; a median portion having a substantially constant outer fifth diameter smaller than said outer fourth diameter; and an elongated distal portion tapering for retrieval in an aorta; and a tubular sheath having: distal ends; an inner sixth diameter at least as great as said outer fifth diameter of said median portion of said dilator and less than said second diameter of said cup connection; a second tube running eccentrically outside said sheath and terminating in a portion for connection to one of said inflating syringes; and a terminal outer balloon connected to said second tube, said terminal outer balloon being disposed at one off said distal ends of said sheath; and introducers fitted with valves for each of said guiding catheters.
