Abstract
A tissue dicing and separation device comprises a housing having an interior that receives tissue for dicing and separation. The device includes a blade assembly connected to a motor and solenoid. The solenoid reciprocates the blade assembly while the motor clocks the blade assembly during each reciprocation cycle. This reciprocating and clocking action of the blade assembly dices and/or minces the tissue. The housing is filled with a fluid and then the blade assembly is continuously rotated to create a vortex within the housing. The vortex causes the diced tissue particles to separate by particle size. Outlets at different positions along the housing permit withdrawal of a slurry of fluid and tissue particles with the tissue particles having a desired size range. The obtained slurry may be used in conjunction with a fistula plug treatment device and method.
