Publication number: 20130046128Abstract: A radiotherapy delivery device is provided comprising an elongated applicator having a proximal end and a distal end having a tip. The distal end is adapted to be introduced into a body including a treatment zone to be located adjacent a target tissue. A radiotherapy emitter is provided that is moveable between the proximal end of the applicator and the treatment zone of the applicator. The applicator includes a window to permit visual confirmation of the location of the radiation emitter and the treatment zone.Type: ApplicationFiled: October 17, 2012Publication date: February 21, 2013Applicant: NEOVISTA, INC.Inventor: NeoVista, Inc.

Patent number: 8365721Abstract: A method for performing intraocular brachytherapy and an apparatus for performing the same is disclosed. The apparatus preferably comprises a hand-held delivery device that advances a radiation source into an associated cannula or probe that is positioned adjacent the target tissue. The handpiece provides for shielded storage of the radiation source when retracted from the cannula and includes a slider mechanism for advancing and retracting the radiation source. The radiation source is mounted to a wire that has a flexible distal end and a relatively stiffer proximal end. A positioning system for the cannula is also disclosed.Type: GrantFiled: August 27, 2010Date of Patent: February 5, 2013Assignee: NeoVista Inc.Inventors: Charles E. Larsen, Richard A. Hillstead, Roelof Trip, Eugene deJuan, Mark S. Humayun, Eberhard Fritz, Rainer Pintaske, Sabine Willenkamp, Gerd T. Phillipps
