Rotating cell collection device

A system for collecting cells, the system comprising:

• a handle portion;
• a rotation mechanism housed within the handle portion, the rotation mechanism comprising an axially translatable rack and a gear portion operably coupled to the rack;
• a rotatable drive wire having proximal and distal portions, the proximal portion being coupled to the gear portion and being rotatably driven by the rotation mechanism in response to axial translation of the rack;
• an offset portion of the drive wire disposed at the distal portion thereof;
• and
• a cell collecting head portion coupled to the offset portion, the head portion rotating eccentrically relative to the proximal portion of the drive wire in response to rotation of the drive wire.

A method for collecting cells, the method comprising:

• delivering to a body cavity an offset portion of a rotatable drive wire, the offset portion having a head member coupled thereto;
• rotating the drive wire about a longitudinal axis thereof;
• in response to rotating the drive wire, rotating the offset portion of the drive wire therewith;
• in response to rotating the offset portion of the drive wire, rotating the head member eccentrically relative to the longitudinal axis of the drive wire;
• in response to rotating the head member, contacting an inner surface of the body cavity with the head portion to collect cells therefrom.
