Stent deployment device
First Claim
1. A stent deployment system comprising a stent and a stent deployment device, wherein the stent is secured over the stent deployment device for the purpose of delivery into an operative position in a human body, the device comprising a plurality of elongate wings, each of which has a length consistent with the length of the stent to be deployed using the deployment device, wherein the wings are arranged circumferentially about a central body which extends from, and is operable through, a catheter;
- the wings being movable between a radially withdrawn delivery position and expanded positions in which they are displaced radially outwards of the body and operable with sufficient force to cause at least partial expansion of the stent carried by the device during movement from the delivery position to an expanded position, and wherein a flow path is defined internally of the wings in the expanded positions thereof, and wherein a temporary valve is provided in such flow path to permit flow of blood though the flow path predominantly in one direction.

Abstract
A stent deployment device over which a stent is securable for the purpose of delivery into an operative position in a human body is provided. The device comprises a plurality of elongate wings, each of which has a length consistent with the length of a stent to be deployed using the deployment device, the wings being arranged circumferentially about a central body which extends from, and is operable through, a catheter. The wings are movable between a radially withdrawn delivery position and expanded positions in which they are displaced radially outwards of the body. A flow path is defined internally of the wings in the expanded positions thereof and a temporary valve is provided in such flow path to permit the flow of blood though the flow path predominantly in one direction. An inflatable annular balloon is preferably provided over the wings to cause final expansion of the stent. Locator arms are deployable from the body to assist in locating the body within a natural heart valve.
