US 11,684,446 B2 · Device for radiosurgical treatment of uterine fibroids

Abstract

Removable marker implants having fiducial markers disposed on multiple elongate members extend and splay laterally outward when deployed thereby providing improved 3D localization and tracking of a portion of the patient's body for stereotactic radiosurgery. Such an approach is particularly useful for tracking of the uterus during radiosurgery treatment of uterine fibroids. Such implants can include an outer sheath that contains the multiple elongate members during delivery into the portion of the body. The elongate members can be slidably disposed within the shaft and advanced into an expanded deployed position by advancement of an applicator shaft or rod within the sheath. Marker implant can also be integrally formed implants with flexible arms having fiducial markers thereon that can be constrained in a sheath for delivery and resiliently splay laterally outward when released from the shaft. Methods of delivery and deployment are also provided.

Dependent claims

A device for placing one or more radiosurgical fiducial markers into a uterus, the device comprising:

the one or more radiosurgical fiducial markers disposed on a distal portion of each of a plurality of elongate members;
and
a sheath in which the plurality of elongate members are at least partly disposed, wherein the plurality of elongate members are movable between a delivery configuration and a deployed configuration,
wherein in the delivery configuration, the plurality of elongate members are substantially contained within the sheath,
wherein in the deployed configuration, the distal portions of each of the plurality of elongate members having the one or more radiosurgical fiducial markers extend through one or more openings in the sheath for placement along the uterus to facilitate 3D visualization and/or tracking of the uterus,
wherein the one or more radiosurgical fiducial markers are fixed relative to each other in the deployed configuration, and
wherein the plurality of elongate members comprise a rigid material thereby fixing the one or more radiosurgical fiducial markers relative to each other in the deployed configuration.
