Abstract
A transurethral system for delivering and depositing fiducial markers usable to delineate the prostate during radiation therapy.
Claims20
A system for delivering and depositing at least one fiducial marker to tissue at an interventional site within a body of a patient, comprising:
- an anchor assembly deployable at the interventional site, the anchor assembly comprising a first anchoring component, a second anchoring component, a connector disposed between the first anchoring component and the second anchoring component, and the at least one fiducial marker, wherein:
- the at least one fiducial marker is made of a radiopaque material incorporated onto at least a portion of the first anchoring component, the second anchoring component, the connector, or a combination thereof, and
- the anchor assembly is configured to hold tissue captured between the first anchoring component and the second anchoring component in a compressed state via the connector such that the at least one fiducial marker delineates a boundary of the tissue;
- and
- a delivery device carrying the anchor assembly, the delivery device comprising:
- an elongate member configured to be inserted into the body of the patient and advanced to the interventional site;
- and
- an actuator usable to deploy the anchor assembly at the interventional site.
A method of delivering at least one fiducial marker to an interventional site within a body of a patient, comprising:
- inserting an elongate member of a delivery device into the body of the patient;
- advancing the elongate member to the interventional site;
- deploying, via an actuator of the delivery device, an anchor assembly at the interventional site, the anchor assembly comprising a first anchoring component, a second anchoring component, a connector disposed between the first anchoring component and the second anchoring component, and at least one fiducial marker made of a radiopaque material incorporated onto at least a portion of the first anchoring component, the second anchoring component, the connector, or a combination thereof;
- and
- positioning the first anchoring component and the second anchoring component to hold tissue captured therebetween in a compressed state via the connector such that the at least one fiducial marker delineates a boundary of the tissue.

- an anchor assembly deployable at the interventional site, the anchor assembly comprising a first anchoring component, a second anchoring component, a connector disposed between the first anchoring component and the second anchoring component, and the at least one fiducial marker made of a radiopaque material, wherein:
- the at least one fiducial marker comprises a radiopaque tag situated between the second anchoring component and the connector, and
- the anchor assembly is configured to hold tissue captured between the first anchoring component and the second anchoring component in a compressed state via the connector such that the at least one fiducial marker delineates a boundary of the tissue;
- and
- a delivery device carrying the anchor assembly, the delivery device comprising:
- an elongate member configured to be inserted into the body of the patient and advanced to the interventional site;
- and
- an actuator usable to deploy the anchor assembly at the interventional site.
