Abstract
A medical device and method of using the device to reinforce and stabilize a compressed tissue is disclosed. The medical device comprises a shaft with a single blade that is biased with a bend, but is elastic enough to be straightened. The end of a cannula is inserted into a tissue, and the blade and shaft are then inserted into a cannula to straightens the blade and direct it to the tissue site. When the blade reaches the tissue site, the blade naturally returns to its bent biased state, and the shaft and blade are then rotated to pulp a volume of tissue. A binding material is then injected into the pulped tissue without removing the tissue.
Claims20
A device for disrupting a biological tissue, comprising:
- a shaft;
- a blade coupled to a distal end of the shaft, wherein the blade has a bent bias along an edge and is configured to elastically straighten;
- and
- a cap coupled to a distal end of the blade.
A method of disrupting biological tissue, comprising the following steps:
- inserting a distal portion of a cannula into a tissue;
- inserting a blade with a bent bias into the cannula to elastically straighten the blade;
- pushing the blade to an open distal portion of the cannula to elastically return to the curved bias;
- and
- moving the blade to disrupt a volume of tissue.
