Filed:

Oct 6, 2007

Appl. No.:

11/868483

Inventors:

Tommy Nguyen - Irvine CA, US
Than Nguyen - Fountain Valley CA, US
Doug Sutton - Pacifica CA, US
George Hermann - Portola Valley CA, US
Luis Urquidi - Oceanside CA, US

Assignee:

Cianna Medical, Inc. - Aliso Viejo CA

International Classification:

A61M 36/12

US Classification:

600007000

Abstract:

Apparatus for delivering brachytherapy to a target tissue region includes an elongate body including a proximal end, a distal end sized for introduction into a tissue tract and carrying a plurality of elongate members including pathways for receiving a source of radiation. The elongate members are movable between collapsed and expanded configurations. During use, a tract is created through tissue, and the elongate body carrying the elongate members is advanced through the tract into a target location with the elongate members in the collapsed configuration. The elongate members are directed to the expanded configuration at the target location, and radiation is delivered to treat tissue at the target location, e.g., by introducing one or more radiation sources along the pathways. The apparatus may include features to prevent overexpansion of the elongate members and/or to facilitate rapid collapse of the elongate members.

Assignee:

Cianna Medical, Inc. - Aliso Viejo CA

International Classification:

A61B 5/06

US Classification:

600424

Abstract:

Apparatus, systems, and methods are provided for localizing lesions within a patient's body, e.g., within a breast. The system may include one or more markers implantable within or around the target tissue region, and a probe for transmitting and receiving electromagnetic signals to detect the one or more markers. During use, the marker(s) are into a target tissue region, and the probe is placed against the patient's skin to detect and localize the marker(s). A tissue specimen, including the lesion and the marker(s), is then removed from the target tissue region based at least in part on the localization information from the probe.
