  • Patent number: 7803102
    Abstract: 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.

  • Publication number: 20090299417
    Abstract: A medical instrument for delivering electrotherapy to tissue that includes an outer support member having a ground plate at a distal end of the outer support member, and a protrusive element having a tip that extends beyond the ground plate. A portion of the protrusive element proximate the ground plate can act as an electrical insulator and a portion of the protrusive element proximate the distal end of the protrusive element can include a first electrode. The protrusive element can be designed to penetrate into tissue below a tissue surface while a tissue contacting surface of the ground plate rests against the tissue surface. Also disclosed are systems incorporating the medical instrument and methods of electrotherapy to subsurface tissue using the medical instrument.

  • Publication number: 20090228008
    Abstract: An implantable segmented intramedullary structure adapted to be received in the intramedullary canal of a bone configurable between a relatively flexible, bent configuration for implantation or extraction and a relatively rigid, straightened configuration for bone treatment. The segmented intramedullary structure comprises a plurality of interconnected segments with a first interface and a complementarily-shaped second interface such that the first interface of a segment cooperatively engages the second interface of an adjacent segment. The segments define a channel for a tensioning member to lock the structure in a compressed configuration.
