1. A device adapted to manufacture a sutureless bioprosthetic stent graft, comprising:
- a mandrel having a selected diameter and adapted to have positioned thereon a stent graft having a biomaterial sheath; and
an energy irradiation controller, including;
an energy irradiator, a mapper operative to generate a three-dimensional target site map of a target site, a patternizer operative to synchronize an irradiating pattern with the three-dimensional target site map, and an energy director configured to substantially automatically direct energy from an energy irradiator to the target site in accordance with the irradiating pattern to weld together the biomaterial sheath.

Abstract
An apparatus for making a bioprosthetic stent graft is disclosed, the stent having a stent frame and a biomaterial sheath suturelessly bonded to the stent frame. An automated energy irradiator guidance system is disclosed which reduces the potential for human error and improves the consistency and repeatability of tissue welding techniques. The system includes a mapper, a patternizer, an energy director and can additionally include an energy regulator. An interface is included, allowing pattern creation, selection and editing by a user. The system further provides control of energy irradiator parameters for use in tissue welding.

21. A sutureless bioprosthetic stent graft manufacturing apparatus, comprising:
-
a mandrel having a selected diameter and adapted to have positioned thereon a stent graft having a biomaterial sheath;
an automated tissue welding apparatus for welding tissue at a weld site, including;
a weld site topographer operative to generate a displayable topographical image of the weld site, a weld patternizer operative to topographically synchronize an irradiating pattern with the topographical image, an energy transmitter coupled to a energy source and structured to transmit energy from the energy source to a targeted tissue weld site to weld the biomaterial, and an energy positioner configured to automatically control positioning of the energy to irradiate the weld site to weld the biomaterial in accordance with the irradiating pattern. - View Dependent Claims (22, 23, 24, 25)
