System, methods, and instrumentation for image guided prostate treatment

A method for aiding the performance of an image-guided procedure, comprising:

• inserting a catheter device into an anatomy of a patient, the catheter device including a catheter portion having a plurality of lumens therein and a balloon portion;
• inflating the balloon portion by passing a fluid through at least one of the plurality of lumens that is in fluid communication with the balloon portion so that the catheter device is removable fixed within the anatomy of the patient;
• rendering at least a portion of the catheter device visible to a first imaging modality;
• imaging the anatomy of the patient using an imaging device to obtain image space data of a first portion of the catheter device rendered visible to the first imaging modality,
• wherein the first portion of the catheter device visible to the imaging modality includes a special path of the plurality of lumens exterior to the catheter portion and housed within the balloon portion, and
• wherein the image space data includes the position of the first portion of the catheter device within the anatomy of the patient;
• rendering the first portion of the catheter device visible to a second imaging modality;
• imaging the first portion of the catheter device with the second imaging modality, wherein the second imaging modality includes one or more position indicating elements whose position is tracked by a tracking device;
• inserting a dynamic referencing device into a dynamic referencing lumen of the plurality of lumens of the catheter device to dynamically reference the anatomy of the patient during the image guided procedure;
• determining coordinates of the first position of the catheter device in a coordinate system of the tracking device, the coordinates comprising patient space data;
• and
• registering the imaging space data to the patient space data for use during an image guided procedure to the anatomy of the patient.

An image guided system, comprising:

• a image guided system for aiding the performance of an image guided procedure, the image guided system including
• a catheter portion having first and second ends and a plurality of lumens,
• a balloon portion at the second end of the catheter portion that, when inflated, removably fixes the image guided system into a portion of an anatomy of a patient,
• wherein at least a portion of the catheter device includes a special path of the plurality of lumens exterior to the catheter portion and housed within the balloon portion;
• a registration device accommodated within a first lumen of the plurality of lumens, the registration device having a first set of one or more position indicating elements for providing patient space data regarding the second end of the catheter position using a tracking device;
• a referencing device accommodated within a second lumen of the plurality of lumens, the referencing device having a second set of one or more position indicating elements for dynamically referencing the portion of the anatomy of the patient, the second lumen being distinct from the first lumen;
• and
• a computer element operable to register image space data and the patient data for use during the performance of the image guided procedure, the image space data regarding an imaging of the portion of the anatomy of the patient and a portion of at least one of the plurality of lumens.
