Abstract
Abstract A gynecological aspiration tip is made as a flexible cylindrical hollow tube (1) having a slot (2) in its wall. The slot (2) communicates with the interior of the tube (1) and is located at a distal end (3) of the tube. The slot (2) is open on the side of a face (4) of the distal and (3) of the tube (1). A proximal end (5) of the tube (1) is adapted to communicate with a source of vacuum.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
111 words
A gynecological aspiration tip comprising a flexible, cylindrical hollow tube means having an open distal end and a proximal end for extraction of gravidic or pathologically changed endometrium simultaneously from the uterine fundus and lateral walls, a single slot means defined by a side wall of said tube means extending from said open distal end along said tube means toward said proximal end and said slot means communicating with the interior of the tube means, said distal end including said slot means being compressible to reduce the circumferential length during passage through the cervical canal, said proximal end of the tube means being adapted to communicate with a source of vacuum.
Claim 2
Dependent Claim
111 words
A gynecological aspiration tip comprising a flexible, cylindrical hollow tube means having an open distal end and a proximal end for extraction of gravidic or pathologically changed endometrium simultaneously from the uterine fundus and lateral walls, a single slot means defined by a side wall of said tube means extending from said open distal end along said tube means toward said proximal end and said slot means communicating with the interior of the tube means, said distal end including said slot means being compressible to reduce the circumferential length during passage through the cervical canal, said proximal end of the tube means being adapted to communicate with a source of vacuum.
Claim 3
Dependent Claim
53 words
A gynecological aspiration tip as claimed in claim 1, wherein a ratio of a width of the slot means to its length ranges within about 1:6 to about 1:10, and the width of the slot means equals from about one-third to about one-half the outside diameter of the flexible cylindrical hollow tube means.
