FOERFARANDEN OCH ANORDNING FOER FOERENANDE AV ANATOMISKA STRUKTURER.

摘要

The invention provides encircling devices (10) by which anatomical structures (12), such as blood vessels, fallopian tubes, ureters, vas deferens and outer nerve sheaths may be anastomosed. Such an encircling device (10) provides an opening that receives an end (12) of a tubular anatomical structure having a prepared opening, and the tubular structure is anastomosed to a second anatomical structure having a prepared opening by tethering (19) to hold the two structures to the encircling device (10) holding the structures under radial stress in apposition to each other to form a fluid-tight peripheral seal around their openings. Such devices may be used in the manner described to join a tubular anatomical structure to a second anatomical structure having a cavity, e.g. a fallopian tube to a uterus or a ureter to the bladder.
