The radioactive material provides a dose of radiation to the target surgical site. The surgical implant may also be formed from titanium, stainless steel or polymers. A surgical applier is provided for allowing a surgeon to apply the implant to a patient's tissue.

A method for treating a tumor, comprising identifying a tumor as a breast cancer tumor and implanting in the tumor identified as a breast cancer tumor, as least one diffusing alpha-emitter radiation therapy (DaRT) source (21) with a suitable radon release rate and for a given duration, such that the source (21) provides during the given duration a cumulated activity of released radon between 3.5 Mega becquerel (MBq) hour and 9 MBq hour, per centimeter length.

An end effector for a surgical fastening device is provided. The end effector includes a body defining a longitudinal axis, one or more fasteners, an anvil, and a pusher. Each fastener has an unformed configuration and a formed configuration. Each fastener includes first and second arms that extend in opposite directions. The first arm has first and second elbow segments. The first elbow segment is configured to bend as the fastener is formed. The second elbow segment is configured to remain unbent as the fastener is formed. The pusher is configured to advance the fastener distally through the body and into engagement with the anvil to form the fastener against the anvil.

A device and method for radioembolization in the treatment of cancer cells in the body. In preferred embodiments, a radiomicrosphere is formed from a resin where an alpha emitting isotope is used for tumoricidal purposes. As the alpha emitter decays, daughters of the alpha decay are captured by the resin. In accordance with the preferred embodiments, the resin is polyfunctional where the resin has at least three different types of functional groups for cation binding. In preferred embodiments, the three functional groups bonded to the resin include a carboxylic acid group, a diphosphonic acid group, and a sulfonic acid group. In further embodiments, the device comprises at least two isotopes; wherein a first isotope is for therapeutic purposes and a second isotope is for dosimetric purposes. The second isotope is a positron emitter for PET based dosimetry. In preferred embodiments, a post-treatment radiation absorbed dose is determined using the present invention, allowing both treatment and treatment efficacy to be provided to a cancer patient.

This disclosure provides design, material, preparation methods, and use alternatives for medical devices. An example method of preparing a stent comprises applying a coating to a portion of the stent at a medical treatment facility, the coating including a plurality of radioactive elements and a substrate. The plurality of radioactive elements are mixed with the substrate to form a mixture such that the plurality of radioactive elements are dispersed within the substrate prior to the coating being applied on the stent.

An ophthalmic radiation device using a polymeric radiation-source implemented as either a polymer molecularly bonded with a radioisotope or a polymeric encasement of a radioisotope.

Disclosed is a bore based medical system comprising a camera carrier configured to be mounted in the bore based medical system and configured to monitor and/or track patient motion within said bore based medical system during radiotherapy, the bore based medical system comprising a rotatable ring-gantry configured to emit a radiotherapy beam focused at an iso-center of the bore based medical system, wherein the ring-gantry is configured to rotate at least partly around a through-going bore having a front side and a back side, configured to receive from said front side, a movable couch configured to be moved into and out from the through-going bore, wherein further the through-going bore comprises an inner side facing an inside of the bore, and wherein the camera carrier is configured to be mounted inside the bore in connection with the inner side of the through-going bore.

A method for tracking and irradiating a target using a radiotherapy apparatus, a device and a radiotherapy apparatus are provided. The radiotherapy apparatus includes a first ray source, a second ray source, and at least one detector. The method includes: moving the first ray source to a first location to emit a ray beam; receiving the ray beam emitted from the first ray source at the first location and generating first image data of a target according to the received ray beam, by the detector; and adjusting the second ray source according to the first image data to make the second ray source move to the first location and an emitted ray beam pass through the target, wherein a time taken for the second ray source to move to the first location is a positive integer multiple of a preset respiratory period of a patient.

This invention relates to a ceramic module for assembly into a therapeutic device for treating a human or animal body with irradiation of far infrared radiation and low dose ionizing radiation based on radiation hormesis effect. More specifically, the invention relates to a ceramic module that simultaneously emits far infrared radiation within 3-16 μm wavelength spectrum and ionizing radiation at a specific dose rate in the range of 0.1-11 μSv/h (micro-Sieverts per hour). Said ceramic module may be used alone or serve as components of a therapeutic device for increasing physiologic performance, immune competence, health, and mean lifespan of human or animal.

A method and system may include a therapeutic agent having a radioactive source enclosed by a container. The container may be placed within a cavity of a medical device for treating animal tissue. The method and system allows a radioactive source to be manufactured in such a manner so as to control and spatially modulate the delivery of radiation doses to a treatment area of animal tissue, such as for tissue of humans. From the container, radiation doses and/or a radiation field are produced by the radiation source. The geometry and size of the radiation doses are controlled by the geometry of the container and the geometry of the radiation source as well as the type, number, and geometry of holes/slots in either the source material and/or a surface of the container.
