DEVICE, SYSTEM AND METHOD FOR IMPLANTATION OF FILAMENTS AND PARTICLES IN THE BODY

摘要

A method of introducing continuous lengths of filament into the body in surgical procedures in which it is desirable to place a significant amount of material into the body through a small portal. The material so introduced may serve to bulk a tissue of cavity of the body or to occlude a vas, as well as to introduce diagnostic or therapeutic agents into a site in the body. A device for implementing the method has a mechanism for feeding the filament through a conduit in such a manner that sufficient force is applided to the filament that it is forced into the desired site. In one embodiment, a system of reciprocating cannulae and synchronized grippers is used to supply the requisite force to the filament.
