Abstract
Abstract A vaginal drape having a substantially frustoconical configuration, and a perimeter expandable along the length thereof. The drape is adapted to be secured about the cervix uteri of a human female. The vaginal drape can be used alone or in cooperation with an insertion unit or a kit for conducting medical and/or surgical procedures on the uterus. The drape provides an aseptic region while a medical procedure is being performed on the uterus through the vaginal canal.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
160 words
A sterile vaginal drape structure comprising: (A) a flexible tube having a proximal end and a distal end, and a circumferential wall having defined therein a plurality of pleats which: extend substantially the full length of said tube; are in an initially folded configuration; are captured and contained about said distal end but are free at said proximal end; and are unfolded to produce a configuration the distal end of which is adapted to be received within the vaginal canal of a human female while the proximal end defines a relatively larger, free-form opening; and (B) securement means functionally associated with said distal end which retains at said distal end said pleats in said folded configuration and which detachably associates said distal end about the cervix uteri of said human female, said securement means including an inwardly extending flange adapted to surround said cervix uteri; and (C) said proximal end being expandable to the full unfolded circumference of said tube.
Claim 2
Dependent Claim
160 words
A sterile vaginal drape structure comprising: (A) a flexible tube having a proximal end and a distal end, and a circumferential wall having defined therein a plurality of pleats which: extend substantially the full length of said tube; are in an initially folded configuration; are captured and contained about said distal end but are free at said proximal end; and are unfolded to produce a configuration the distal end of which is adapted to be received within the vaginal canal of a human female while the proximal end defines a relatively larger, free-form opening; and (B) securement means functionally associated with said distal end which retains at said distal end said pleats in said folded configuration and which detachably associates said distal end about the cervix uteri of said human female, said securement means including an inwardly extending flange adapted to surround said cervix uteri; and (C) said proximal end being expandable to the full unfolded circumference of said tube.
Claim 3
Dependent Claim
24 words
The vaginal drape structure of claim 1, wherein said securement means comprises a flexible ring of a size adapted to receive said cervix uteri.
Claim 4
Dependent Claim
15 words
The vaginal drape structures of claim 1 wherein said flange is provided with a bioadhesive.
