Embodiments of the disclosure may be drawn to brachytherapy source assemblies. Exemplary source assemblies may include a cable made of an electrically non-conductive material and a guide wire coupled to and extending from a distal end of the cable. The guide wire may have a distal end region and a proximal end region, and the guide wire may have a length that is shorter than a length of the cable. The assembly may also include a capsule located at a distal end region of the guide wire, and the capsule may include a chamber configured to contain a radioactive source. The capsule may be formed of a non-ferromagnetic material and may have a ferromagnetic coating that at least partially covers the capsule.

A diffusing applicator is provided and generally includes a head unit, and extension shaft, and a dispensing device. The head unit includes a fluid receiving space and a plurality of dispensing passageways in communication the fluid receiving space. The extension shaft is securely connected to head unit. The dispensing device holds a fluid and is connected to the extension shaft. The dispensing device is in communication with the plurality of dispensing passageways.

The present invention relates to an applicator device (10; 10; 10″) for interventional radiotherapy treatments (brachytherapy), perineal intervention and/or diagnostic procedures on a patient, comprising a substantially plate-like and on the whole T-shaped main body (1; 1′; 1″), which main body (1; 1′; 1″) comprises two peripheral portions (19) having a profile with curved, preferably concave, route, each one intended to abut on a patient's leg.

A device for depositing a solid medicament, having: a cannula (12) having a tip (18) provided at the distal end; and an attachment (20) which receives a proximal region of the cannula and has ridges (24, 26, 28) extending perpendicularly to the longitudinal axis of the cannula; and a plunger (16) which is movable progressively inside the cannula and has a handle (38). The handle (38) has rib-like retaining elements which extend in the longitudinal direction of the plunger (16), are spaced apart therefrom and are connected to the plunger in each case using a connecting element which can be severed at least in one of its end regions by interacting with the attachment (20).

A delivery assembly includes a console including a vial containment region and a vial engagement mechanism extending from the console within the vial containment region. The engagement mechanism is configured to engage a vial assembly. The delivery assembly further includes a sled assembly removably coupled to the console at the vial containment region and a safety shield removably coupled to the console over the vial containment region such that the vial engagement mechanism and the sled assembly are encapsulated within the safety shield when the safety shield is coupled thereto. The sled assembly, the vial assembly, and the safety shield are configured to inhibit radioactive emissions from within the vial containment region.

Markers, medical instruments, and/or medical devices have a composition and/or other features or characteristics such that they will generate twinkling artifacts when imaged with ultrasound. In this way, the markers, medical instruments, and/or medical devices can be detected and localized using ultrasound. Ultrasound technical specifications that are optimized to generate twinkling artifact signatures are selected and used to facilitate localization of such markers, instruments, and/or devices.

A rotating shield brachytherapy (RSBT) apparatus includes a radiation source, at least one applicator, a catheter, a catheter drive assembly, a robotic positioning system, and a connection system. The applicator(s) is configured to be inserted or implanted into a patient. A distal end portion of the catheter has at least one radiation shield and is configured to receive a wire-mounted radiation source. The catheter drive assembly causes helical motion of the catheter and engages the proximal end portion of the catheter to selectively rotate the catheter about a longitudinal axis. The robotic positioning system aligns the catheter drive assembly, in both position and angular orientation at a modifiable rate, with the applicator(s), or to any programmed point in space. The connection system couples the catheter drive assembly to the applicator(s), and further decouple the catheter drive from the applicator(s). When the applicator(s) is coupled to the catheter drive assembly, the catheter can be advanced into, and out of, the at least one applicator at a variable rate through operation of the catheter drive a

A method and system for combination therapy utilizing local drug delivery and radiotherapy at a target site of body tissue are provided. The delivery system comprises a source electrode adapted to be positioned proximate to a target site of internal body tissue. A counter electrode is in electrical communication with the source electrode, and is configured to cooperate with the source electrode to form a localized electric field proximate to the target site. A cargo may be delivered to the target site when exposed to the localized electric field. Radiotherapy is applied to the target site in combination with the local drug delivery.

Embodiments of the disclosure may be drawn to brachytherapy applicators. Exemplary applicators may include an interstitial tube having a body with a proximal end and a distal end and a central conduit extending from the distal end of the body, wherein the central conduit includes a proximal opening, a distal opening, and a channel extending from the proximal opening to the distal opening, and wherein the proximal opening is offset from an axis of the body. The proximal opening may be configured to fluidly connect to a brachytherapy guide tube, and the channel of the central conduit may be dimensioned to receive at least one of a needle or a catheter therethrough.

A vial assembly includes a vial and a needle with at least one port. The vial includes a particulate material, a septum, a neck region including a first width, and a particulate region including a second width greater than the first width. The vial assembly is configured to move to a locked position. The needle may be configured to puncture the septum with the at least one port configured to be in the neck region when in the locked position. The at least one port may be configured to inject a fluid into the vial assembly to mix with the particulate material upon actuation of a vial engagement mechanism in a first direction and to receive a resulting mixed fluid from the vial assembly upon actuation of the vial engagement mechanism in a second direction opposite the first direction.
