Split sheath deployment system
First Claim
1. A method of delivering and deploying a radially expandable prosthesis using a delivery and deployment device, the delivery and deployment device comprising a prosthesis, a proximal release mechanism releasably retaining a proximal portion of the prosthesis and having a first resistance, and a distal release mechanism releasably retaining a distal portion of the prosthesis and having a second resistance, the method comprising the steps of:
- biasing in the delivery and deployment device the relationship between the first resistance and the second resistance;
positioning the delivery and deployment device so that the prosthesis is adjacent an area to be treated; and
actuating the proximal and distal release mechanisms in a single coordinated movement so that the proximal release mechanism releases the proximal portion of the prosthesis and the distal release mechanism releases the distal portion of the prosthesis in a predetermined manner.

Abstract
A device for delivering and deploying a radially expandable prosthesis is disclosed and comprises a proximal prosthesis release mechanism having a first resistance and a distal prosthesis release mechanism having a second resistance. The device further comprises an actuation mechanism for actuating the distal and proximal release mechanisms in a single coordinated movement and a biasing compensator for regulating the relationship between the first resistance and the second resistance. Additional aspects of the invention include devices and methods for delivering and deploying a radially expandable prosthesis.
