Abstract

Methods are described for treating a target tissue with a radioisotope. Some methods include determining a distance between a target tissue and a surface of a matrix material to be positioned adjacent the target tissue and, based on the determined distance, determining an activity to be mixed with the matrix material to obtain a desired activity concentration. Some methods further include mixing the radioisotope with the matrix material. In some embodiments, the matrix material is a bone cement, and the target tissue is a tumor in a bone. The radioisotope may be a beta-emitting radioisotope mixed in the cement at a concentration to form a radioactive cement.

Claims17

Dependent claims

A tissue removal device, comprising:

an elongate body having an inner lumen extending from a proximal portion to a distal end;
an elongate member extending through the lumen, the member having a long axis and a distal portion that extends in a direction transverse to the long axis, the member being slidable and rotatable relative to the elongate body when extending through the lumen, such that when the elongate member is advanced distally relative to the elongate body, the distal portion of the elongate member is positioned distally of the distal end of the elongate body;
and
an actuator attached to the proximal portion of the elongate body and configured to control at least one of axial and rotational movement of the elongate member;
wherein, upon insertion of the device into a patient and actuation of the actuator, the elongate member is configured to cut a tissue in the patient by the at least one of axial and rotational movement.
