US 12,070,619 B2 · Radiotherapy applicator with perpendicular or angled radial dispensing

Abstract

A device for implanting radiotherapy seeds in a tumor. The device includes a delivery tube having a distal end designed to enter the tumor, and defining an internal channel and an elongate applicator carrying one or more radiotherapy seeds each having a length of at least 1 millimeter, the applicator passing through the internal channel of the delivery tube. When a distal end of the elongate applicator is near a distal end of the delivery tube, it assumes an angle relative to an axis of the delivery tube, such that seeds ejected from the elongate applicator enter the tumor at an angle relative to the axis of the delivery tube.

Dependent claims

A method of inserting radiotherapy seeds into a tumor, comprising:

inserting a delivery tube to a first depth in the tumor;
ejecting a plurality of radiotherapy seeds from the delivery tube into the tumor, while the delivery tube is at the first depth, wherein each of the plurality of radiotherapy seeds is ejected at an angle relative to an axis of the delivery tube, and wherein the plurality of radiotherapy seeds are ejected in at least two different radial angles;
and
moving the delivery tube to a second depth in the tumor and ejecting one or more radiotherapy seeds from the delivery tube into the tumor at the second depth.
