The present invention related to an interstitial marker for localizing an organ, tumor or tumor bed within a mammalian body wherein said marker has a proximal end, a distal end, and a continuous intervening length, at least a portion of the intervening length of said marker being visible under at least one imaging modality and having a flexibility such that said marker follows movements and changes of shape of said organ, tumor or tumor bed.

Elongated marker for soft tissue volume identification

A system for and method of applying non-invasive brachytherapy to a targeted volume within a protruding organ of a patient, employs an applicator constructed so as to be positioned relative to the organ so that an enhanced dose of divergent radiation is deliverable from at least two locations at or very near the periphery of the organ transcutaneously to the targeted volume of the protruding organ from at least two directions so that a higher dose is delivered to the targeted volume than to tissue surrounding the targeted volume. The treatment planning, and image guidance techniques are also described.

Peripheral radiotherapy of protruding conformable organs

The present invention is related to an interstitial marker for localizing an organ, tumor or tumor bed within a mammalian body wherein said marker has a proximal end, a distal end, and a continuous intervening length, at least a portion of the intervening length of said marker being visible under at least one imaging modality and having a flexibility such that said marker follows movements and changes of shape of said organ, tumor or tumor bed.

Elongated markers for soft tissue volume identification

A general purpose radiotherapy device can be fabricated to net or near-net shape and then made radioactive in a single activation step. The device is made at least partially of a transmutable material which is transformable to a radioisotope-containing material upon activation by an accelerated beam of charged particles, such as protons, deuterons or alpha particles. The transmutable material is preferably rhodium and the radioisotope-containing material is preferably palladium-103.

Transmutable radiotherapy device

A flexible, continuous, axially elastic interstitial brachytherapy source is capable of elongating, shrinking and/or flexing in response to changes in the size and/or shape of a tumor, tumor bed, lesion or other tissue with which the source is in contact. In one embodiment, the source is in the form of a wire coil. The flexible and expandable/contractible nature of the source allows it to provide therapeutically effective treatment to dynamic tissue as it swells, shrinks and/or changes in shape.

Flexible, continuous, axially elastic interstitial brachytherapy source

A brachytherapy device in the form of a radioactive coiled wire. The wire used to form the coil is typically between about 10 and 200 micrometers in diameter, and the coil formed from the wire has an outer diameter of between about 25 micrometers and about 1000 micrometers. The coil can be formed first from a wire and then made radioactive. Alternatively, the wire can be made radioactive first and then formed into a coil. Methods of incorporating a radioisotope into the wire or coil include, for example, nuclear transformation and ion implantation, which do not affect the flexibility and other mechanical properties of the coil. Thin radioisotope films can also be applied to the wire.

Coiled brachytherapy device

A general purpose radiotherapy device can be fabricated to net or near-net shape and then made radioactive in a single activation step. The device is made at least partially of a transmutable material which is transformable to a radioisotope-containing material upon activation by an accelerated beam of charged particles, such as protons, deuterons or alpha particles. The transmutable material is preferably rhodium and the radioisotope preferably comprises palladium-103. The beam energy and device dimensions are selected so that energy from the beam in the range which is most likely to produce a desired transmutation reaction in the device is absorbed, while at least a portion of the energy which is insufficient to effect the desired transmutation reaction is not retained in the device.

A synovial prosthetic member includes a body having an articulating surface and an anchor surface, the articulating surface being configured for articulation with another articulating surface of a synovial joint, the anchor surface being configured for cementing to bone, the body being composed of ultrahigh molecular weight polyethylene (UHMWPE), the anchor surface having been subjected to treatment by either ion implantation, ion beam assisted deposition, or sputter deposition.

A general purpose implantable radiotherapy device for delivering a predetermined dose of radiation in a predetermined radiation pattern. The device includes a biocompatible template adapted for implantation at a treatment site in a patient, and one or more radiation sources which are incorporated directly into at least a portion of the template, preferably by ion implantation methods. The shape of the radiation pattern from the device is determined at least in part by the location and distribution of the radiation source or sources incorporated into the template, and not solely by the shape of the template. The device is suitable for a wide variety of radiotherapy applications.

Implantable radiotherapy device

Catheters including at least one component having a tissue interfacing surface characterized by a substantially nonleaching surface treatment of antimicrobial metal. The component can be a subcutaneous cuff, and the antimicrobial metal can be silver. The process for implanting the silver atoms can include dry coating the tissue interfacing surface of the catheter by way of ion beam assisted deposition. Alternatively, the silver can be introduced into the tissue interfacing surface by ion implantation.
