Abstract
Abstract A method and device for simultaneously collecting cytology cell samples from the endocervix and exocervix are disclosed. The device includes a handle for manipulating and rotating the device. Adjacent the handle is an intermediate cell collecting surface which is sized and configured to scrape cell samples from the exocervix when it is in contact with the exocervix and the device is rotated. The device also includes a distal cell collecting surface adjacent the intermediate cell collecting surface. The distal section is sized and configured to scrape cytology cell samples from the endocervical canal when it is located within the canal and in contact with the walls thereof and the device is rotated. The distal and intermediate surface are further positioned on the device with respect to each other to enable the endocervical canal and exocervix to be scraped simultaneously as the device is rotated.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
186 words
A cervical cytology device for simultaneously collecting cytology cell samples from the endocervix and exocervix, said device comprising: a handle for manipulating and rotating said device and having a handle shaft bent to provide a proximally extending handle portion and a laterally extending offset portion; an intermediate region, with a shaft surrounded by cell collecting means attached at one end to said laterally extending offset portion of said handle and having a surface sized and configured to scrape cytology cell samples from the exocervix when said device is rotated and said intermediate collecting means is in contact with the exocervix; a distal region with a shaft surrounded by cell collecting means attached to said shaft of said intermediate cell collecting means, said collecting means having a surface sized and configured to scrape cytology cell samples from the endocervix when the device is rotated and said distal collecting means is in contact with the endocervix; said intermediate region shaft being integral with said distal region shaft but extending laterally from said distal region shaft said handle portion being axially aligned with said shaft of said distal region.
Claim 2
Dependent Claim
186 words
A cervical cytology device for simultaneously collecting cytology cell samples from the endocervix and exocervix, said device comprising: a handle for manipulating and rotating said device and having a handle shaft bent to provide a proximally extending handle portion and a laterally extending offset portion; an intermediate region, with a shaft surrounded by cell collecting means attached at one end to said laterally extending offset portion of said handle and having a surface sized and configured to scrape cytology cell samples from the exocervix when said device is rotated and said intermediate collecting means is in contact with the exocervix; a distal region with a shaft surrounded by cell collecting means attached to said shaft of said intermediate cell collecting means, said collecting means having a surface sized and configured to scrape cytology cell samples from the endocervix when the device is rotated and said distal collecting means is in contact with the endocervix; said intermediate region shaft being integral with said distal region shaft but extending laterally from said distal region shaft said handle portion being axially aligned with said shaft of said distal region.
Claim 3
Dependent Claim
14 words
A device, as claimed in claim 1, wherein: the included angle is about 85°.
Claim 4
Dependent Claim
35 words
