Abstract
Abstract The device comprises an elongated tubular sheath which is adapted to be inserted into the vagina of a patient, and the distal end portion of which is adapted to engage the cervix of the patient to locate the sheath in the vagina. An aspirator pipette is slidably engaged in the sheath, to be extended from the sheath into the endocervical canal and/or the uterine cavity of the patient, or alternately to be retracted into the sheath from the canal, while the sheath is engaged with the cervix. In addition, there are means whereby after the pipette has been retracted into the sheath, a specimen can be discharged from the same onto a repository for the specimen, as well as means whereby the sheath can be maintained in the vagina while the specimen is discharged onto the repository.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
248 words
A device for collecting biopsy specimens from the female genital tract comprising an elongated tubular sheath which is adapted to be inserted in the vagina and has an open-ended nose at the distal end thereof adapted for insertion in the cervix, said sheath being adapted in length to extend outside of the vagina when the nose is so inserted, and having an open-ended aspirator tube reciprocably engaged therein, said tube having means thereon whereby it can be reciprocated from a point outside of the vagina, and the distal end portion of said tube being adapted to be extended forwardly through and beyond the open end of the nose into the uterine cavity, and alternately retracted into the sheath from the cavity, there being means on the proximal end portion of the tube whereby suction can be generated therein while the distal end portion thereof is so extended, and said distal end portion of the tube being flexible, but having a memoried curve therein, whereby the distal end of the tube deflects toward the wall of the cavity when said portion is extended thereinto, yet said portion is accommodatable within the sheath when it is retracted therein, and the opening in said distal end of the tube being in substantIal coincidence with the distal end of the curve so that points on the periphery of the cavity can be sampled by applying suction to the tube while the distal end thereof is deflected toward the wall of the cavity.
Claim 2
Independent Claim
248 words
A device for collecting biopsy specimens from the female genital tract comprising an elongated tubular sheath which is adapted to be inserted in the vagina and has an open-ended nose at the distal end thereof adapted for insertion in the cervix, said sheath being adapted in length to extend outside of the vagina when the nose is so inserted, and having an open-ended aspirator tube reciprocably engaged therein, said tube having means thereon whereby it can be reciprocated from a point outside of the vagina, and the distal end portion of said tube being adapted to be extended forwardly through and beyond the open end of the nose into the uterine cavity, and alternately retracted into the sheath from the cavity, there being means on the proximal end portion of the tube whereby suction can be generated therein while the distal end portion thereof is so extended, and said distal end portion of the tube being flexible, but having a memoried curve therein, whereby the distal end of the tube deflects toward the wall of the cavity when said portion is extended thereinto, yet said portion is accommodatable within the sheath when it is retracted therein, and the opening in said distal end of the tube being in substantIal coincidence with the distal end of the curve so that points on the periphery of the cavity can be sampled by applying suction to the tube while the distal end thereof is deflected toward the wall of the cavity.
Claim 3
Dependent Claim
23 words
The device according to claim 1 wherein the distal end portion of the tube is slidably guided in the nose of the sheath.
Claim 4
Dependent Claim
30 words
The device according to claim 2 wherein the sheath is substantially circumferentially closed along the length thereof between the nose and a point on the sheath outside of the vagina.
Claim 5
Dependent Claim
21 words
The device according to claim 1 wherein the distal end portion of the tube is rotatable with respect to the sheath.
Claim 6
Dependent Claim
41 words
The device according to claim 4 wherein there are means operatively interposed between the tube and the sheath whereby the distal end portion of the tube can be indexed to the sheath in a plurality of relatively angularly offset orientations therein.
Claim 7
Dependent Claim
57 words
The device according to claim 5 wherein the tube and sheath include telescopically engageable barrels which are polygonal in cross section, and the tube is retractably inserted in the sheath so that the tube can be reoriented by retracting it from the sheath and rotating it to each new orientation before it is reinserted in the sheath.
Claim 8
Dependent Claim
32 words
The device according to claim 5 further comprising means on the sheath whereby the sheath can be secured to the patient to fix the orientation thereof, by operatively interconnecting a tenaculum therebetween.
Claim 9
Dependent Claim
32 words
The device according to claim 4 further comprising means on the sheath whereby the sheath can be secured to the patient to fix the orientation thereof, by operatively interconnecting a tenaculum therebetween.
Claim 10
Dependent Claim
42 words
The device according to claim 8 wherein the sheath has a clip slidably engaged thereon which is equipped with clamping means that are interengageable between the arms of the tenaculum to clamp the clip to the sheath in a fixed position thereon.
Claim 11
Dependent Claim
33 words
The device according to claim 1 wherein the tube has a length greater than that of the sheath so that it can be reciprocated by manipulating the proximal end portion of the same.
Claim 12
Dependent Claim
34 words
The device according to claim 1 wherein the distal end portion of the sheath has locator means thereon which are adapted to abut the portio vaginalis when the nose is inserted in the cervix.
Claim 13
Dependent Claim
