Abstract
A transurethral system for delivering and depositing fiducial markers usable to delineate the prostate during radiation therapy includes at least one implant or anchor assembly featuring a first anchoring component, a second anchoring component, and a connector. A delivery device featuring a handle assembly, an actuator, and an elongate member delivers the implant or anchor assembly to an interventional site.
Core Innovation
A transurethral prostate fiducial-delivery system for radiotherapy is described, where an anchor assembly is deployable at an interventional site within a body of a human patient. The anchor assembly includes a first anchoring component, a second anchoring component, a connector, and at least one fiducial marker, and the system is configured to deliver and deposit the fiducial marker to tissue at the interventional site.
The at least one fiducial marker comprises a sheet of a radiopaque material that forms an interference fit between at least one of the first anchoring component or the second anchoring component and the connector. Radiopaque material examples include gold, platinum, and tantalum, and the fiducial marker is detectable by imaging to delineate prostate boundaries for imaging and radiation targeting.
A fiducial delivery device carries and deploys the anchor assembly at the interventional site, and the device includes an elongate member to be inserted into the body and advanced to the interventional site. The device includes an actuator usable to deploy the anchor assembly at the interventional site, and the partial content also describes fiducial markers that can include radiopaque tags and/or dye or contrast delivery.
Claims Coverage
The partial claims provided include one independent claim. This independent claim covers a system for delivering and depositing at least one fiducial marker to tissue at an interventional site using an anchor assembly and a fiducial delivery device with an elongate member and an actuator, with the fiducial marker configured as a radiopaque sheet forming an interference fit with the connector and an anchoring component.
Radiopaque sheet interference fit fiducial marker
The at least one fiducial marker comprises a sheet of a radiopaque material that forms an interference fit between at least one of the first anchoring component or the second anchoring component and the connector.
Anchor assembly deployable at interventional site
An anchor assembly deployable at the interventional site comprising a first anchoring component, a second anchoring component, a connector, and the at least one fiducial marker.
Fiducial delivery device with elongate member and actuator
A fiducial delivery device carrying the anchor assembly, comprising an elongate member to be inserted into the body of the human patient and advanced to the interventional site, and an actuator usable to deploy the anchor assembly at the interventional site.
Across the independent claim, the coverage centers on an anchor assembly with first and second anchoring components and a connector, where the fiducial marker is a radiopaque sheet configured to form an interference fit between the connector and an anchoring component, and the anchor assembly is delivered and deployed using an elongate member and an actuator.
