Abstract
A method for preparing a bone including percutaneously forming a path to the cancellous bone using a multi-lumen cannula, providing a first passage to the cancellous bone in a central lumen and a second passage in a concentric outer lumen, introducing a rinsing fluid in one of the passages to rinse bone marrow and other soft tissue from the cancellous bone, and removing the rinsed bone marrow from the other passage. Also, a method for percutaneously treating a tissue affected by a lesion, including introducing a rinsing fluid in one of the passages to rinse the lesion and removing the rinsed lesion from the other of the passages. Also, a method of treating tissue with a lesion including introducing a thick flowable material through one lumen of the cannula and applying suction through the other lumen of the cannula.
