1. Apparatus for removing tissue and living organisms comprising:
- a first body having a hollow needle with distal and proximal end portions, said needle extending outwardly therefrom and extending into a chamber within said first body on the other end, said first body also having a syringe passageway connected to a jacket surrounding a proximal portion of said needle, said jacket being sealed against the needle at its distal end and providing a space connecting to a plurality of fenestrations in said needle for the introduction of flushing fluid into said needle;
a second body fixable to said first body and having a first bore extending from an end portion of said second body to a side portion of said second body, said side portion having means for connection to a collection vessel, said second body having a second bore extending from said side portion to a chamber within said second body on the other end;
a third body fixable to said second body and having a bore which contains flexible tubing, said tubing being connectable to vacuum means on one end and extending outwardly from an end portion of said third body and into the chamber of said second body on a second end; and
valve means extending from said third body and being in releasable engagement with said tubing for decompressing or compressing said tubing for actuating on-off suction action through said needle, said suction action occurring upon application of pressure to said valve.

Abstract
This invention provides an improved aspirating and flushing device designed for use in in vitro fertilization procedures in which eggs are delicately removed from the human ovary without need for open surgery. Although the device is intended for one-time use only, a permanent, interchangable stainless steel suction valve assembly can be substituted for the disposable valve if desired. The present invention is adaptable for both trans-abdominal laparoscopic procedures, as well as a trans-vaginal procedure that is performed with the aid of ultrasonagraphy.
