Abstract
Abstract A combination exo-endocervical sampler. The sampler includes an elongated handle portion having a free end and a non-linearly tapered row of flags disposed proximate the end opposite the free end. The flags are preferably configured to have a flat sampling surface and a convex opposed surface and are disposed at an acute angle with respect to the handle portion. A spatulate member is disposed on the handle portion proximate the row of flags at a point diametrically opposite thereto. A ledge extends along the handle member proximate its juncture with the spatulate member and serves to assist in the spreading of the separated exo- and endocervical samplers on to a two-tiered microscope slide. Optionally, a secondary row of flags is formed on an upper edge of the spatulate member to sweep the endocervix and transition zone when the device is rotated within the cervical canal.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
88 words
A combination exo-endocervical sampler comprising: an elongated handle portion defining a longitudinal axis; and a plurality of flexible flags disposed in a coplanar row proximate an end of said handle portion, said flags projecting from said handle portion at an acute angle with respect thereto for insertion into the endocervical canal, the lengths of said plurality of flags successively increasing according to a non-linear function wherein the rate of increase in the lengths of the flags changes from shortest flag proximate said free end to a longest flag.
Claim 2
Dependent Claim
88 words
A combination exo-endocervical sampler comprising: an elongated handle portion defining a longitudinal axis; and a plurality of flexible flags disposed in a coplanar row proximate an end of said handle portion, said flags projecting from said handle portion at an acute angle with respect thereto for insertion into the endocervical canal, the lengths of said plurality of flags successively increasing according to a non-linear function wherein the rate of increase in the lengths of the flags changes from shortest flag proximate said free end to a longest flag.
Claim 3
Dependent Claim
45 words
The sampler of claim 1, further including a spatulate member projecting from said handle at a location thereon proximate said longest flag, and medial thereof and diametrically opposed thereto, said spatulate member serving as a stop when the sampler is inserted into the endocervical canal.
Claim 4
Dependent Claim
38 words
The sampler of claim 2 wherein said spatulate member tapers at an upper edge thereof to define a thin edge portion, said edge portion serving to scrap cells from the exo and transition portions of the cervical canal.
Claim 5
Dependent Claim
38 words
The sampler of claim 2 wherein the spatulate member further comprises a row of secondary flags disposed on an upper edge thereof in a mutually coplanar row to sweep the exo- and transition portions of the cervical canal.
Claim 6
Dependent Claim
16 words
The sampler of claim 2 wherein said spatulate member includes a textured surface portion formed thereon.
Claim 7
Dependent Claim
37 words
The sampler of claim 1 further comprising a raised ledge formed on said handle member proximate said longest flag and extending along a portion of the longitudinal axis of the handle member coextensive with said spatulate member.
Claim 8
Dependent Claim
27 words
The sampler of claim 1 wherein each of said plurality of flags has opposed surfaces including at least a first flat surface and a second convex surface.
Claim 9
Dependent Claim
147 words
A combination exo-endocervical sampler comprising: an elongated handle portion defining a longitudinal axis; a plurality of flexible flags disposed in a mutually coplanar row proximate one end of said handle portion and projecting therefrom at an acute angle for insertion into the endocervical canal; an exocervical spatulate member disposed at a location on said handle portion medial of said row of flags, said spatulate member including a base defined by the juncture of the spatulate member with the handle member, said spatulate member serving as a stop when the sampler is inserted into the endocervical canal; and a ledge formed on said handle member proximate said base of said spatulate member and extending along a portion of the longitudinal axis of the handle member coextensive with said spatulate member to assist in the spreading of a sampler of cervical fluid obtained with said sampler onto a slide.
Claim 10
Dependent Claim
147 words
A combination exo-endocervical sampler comprising: an elongated handle portion defining a longitudinal axis; a plurality of flexible flags disposed in a mutually coplanar row proximate one end of said handle portion and projecting therefrom at an acute angle for insertion into the endocervical canal; an exocervical spatulate member disposed at a location on said handle portion medial of said row of flags, said spatulate member including a base defined by the juncture of the spatulate member with the handle member, said spatulate member serving as a stop when the sampler is inserted into the endocervical canal; and a ledge formed on said handle member proximate said base of said spatulate member and extending along a portion of the longitudinal axis of the handle member coextensive with said spatulate member to assist in the spreading of a sampler of cervical fluid obtained with said sampler onto a slide.
Claim 11
Dependent Claim
157 words
A combination exo-endocervical sampler comprising: an elongated handle portion defining a longitudinal axis; a plurality of flexible flags disposed in a mutually coplanar row proximate one end of said handle portion and projecting therefrom at an acute angle with respect thereto for insertion into the endocervical canal; a spatulate member projecting from said handle at a location medial of said plurality of flags and diametrically opposite thereto, said spatulate member including an upper edge and a base defined by the juncture of the spatulate member with the handle member, said sampler further comprising a raised ledge formed on said handle member proximate said base of said spatulate member and extending along a portion of the longitudinal axis of the handle member coextensive with said spatulate member; and a row of secondary flags disposed on said upper edge of said spatulate member in a mutually coplanar row to sweep the exo and transition portions of the cervical canal.
Claim 12
Dependent Claim
157 words
A combination exo-endocervical sampler comprising: an elongated handle portion defining a longitudinal axis; a plurality of flexible flags disposed in a mutually coplanar row proximate one end of said handle portion and projecting therefrom at an acute angle with respect thereto for insertion into the endocervical canal; a spatulate member projecting from said handle at a location medial of said plurality of flags and diametrically opposite thereto, said spatulate member including an upper edge and a base defined by the juncture of the spatulate member with the handle member, said sampler further comprising a raised ledge formed on said handle member proximate said base of said spatulate member and extending along a portion of the longitudinal axis of the handle member coextensive with said spatulate member; and a row of secondary flags disposed on said upper edge of said spatulate member in a mutually coplanar row to sweep the exo and transition portions of the cervical canal.
Claim 13
Dependent Claim
16 words
The sampler of claim 9 wherein said spatulate member includes a textured surface portion formed thereon.
