Abstract:
1. A medical device for collecting cells from a cyst cavity, the device comprising: an elongate tube having proximal and distal portions and a lumen extending therebetween; a distal opening of the tube disposed at the distal portion; an elongate wire extending through the tube lumen, the wire comprising a generally rigid proximal portion and a generally flexible distal portion including a cell collecting portion for collecting cells from the cyst cavity; wherein the wire proximal portion is configured for being pushed distally through the tube lumen while being at least partially retained within the tube lumen; and wherein the flexible distal portion of the wire is operable in a cell collecting configuration where it is pushed out of the distal opening of the tube and into the cyst cavity to fold over itself in a random tortuous pattern to form a random, tortuous, overlapping path in response to the proximal portion being pushed; wherein the flexible distal portion has a length and flexibility suitable to fold over itself multiple times and to fill the cyst cavity.
