Abstract
The present invention is an in-vivo methodology for repairing a ruptured or fragmented segment of a pre-existing therapeutic appliance which has been previously surgically positioned or implanted within the body of a living human. The repair methodology provides for specific apparatus and techniques using a guiding catheter and deformable, thermoelastic shape-memory alloy rods in order to access and repair the flawed or failing therapeutic appliance in place. The repair methodology thus eliminates the need for surgical excision procedures and avoids the requirement for replacement substitute units in order to alleviate and solve the problem of having a flawed therapeutic appliance in-vivo.
