Abstract
The present invention is of a device and method for positioning a plurality of therapeutic probes with respect to a treatment target within a patient. The method comprises the steps of a) utilizing standard imaging modalities to direct an orientation probe to the target, b) rigidly affixing to the inserted orientation probe a template comprising one or more probe guides, thereby orienting template and probe guides with respect to the target, then c) inserting one or more therapeutic probes through probe guides of the template and into the patient, thereby guiding the therapeutic probes to the treatment target.

A method for guiding a therapeutic probe to a treatment target within the body of a patient, comprising:
- (a) inserting an orientation probe into the body of a patient and positioning said orientation probe so that said orientation probe has a known spatial relationship to said treatment target;
- (b) rigidly affixing to said orientation probe a template which comprises at least one probe guide operable to constrain movement of a therapeutic probe inserted therethrough in a controlled direction, said controlled direction being aligned with said treatment target when said template is rigidly affixed to said inserted orientation probe;
- (c) inserting at least one therapeutic probe through said at least one probe guide into the body of a patient,
- thereby guiding said inserted therapeutic probe to said treatment target.
A device for guiding a therapeutic probe to a treatment target within the body of a patient, comprising a template operable to be rigidly affixed to an orientation probe inserted in the body of a patient, which template comprises at least one probe guide operable to constrain movement of a therapeutic probe inserted therethrough to movement in a controlled direction, such that if an orientation probe is inserted into the body of a patient in such manner that a distal portion of said orientation probe is positioned within said treatment target, and said template is rigidly affixed to said orientation probe, then a therapeutic probe being inserted into the body of a patient through said at least one probe guide will be constrained to move towards said treatment target.
