Multi-component magnesium-based alloy consisting essentially of about 1.0-15.0 wt. % of scandium, about 0.1-3.0 wt. % of yttrium, about 1.0-3.0 wt. % of rare-earth metal, about 0.1-0.5 wt. % of zirconium. Purity degree of magnesium base is not less of 99.995 wt. %. Impurities of Fe, Ni and Cu do not exceed 0.001 wt. % of everyone, the contents of other impurity in an alloy does not exceed 0.005 wt. %. The alloy demonstrates an improved combination of strength, deformability and corrosion resistance at room temperature. The alloy does not contain harmful and toxic impurities. The alloy can be used in the various practical applications demanding a combination of high strength, deformability and corrosion resistance, preferably in the field of medicine.

A positioning device () for treating the inner walls of a resection cavity, which was created by surgically removing of at least a portion of a tumor in a living body, characterized by the fact that the material of the device (), part(s) of the device and accessories of the device () is (are) biologically degradable in the living body. Further a surgical procedure for treating a tumor in a living body of at least one of the former claims, comprising: (a) surgically removing at least a portion of said tumor thereby creating a cavity in the living body's remaining tissue; (b) placing a biodegradable treatment device in said cavity so that the degradable device occupies said cavity; and (c) treating tissue surrounding said cavity by means of said positioning device.

The invention concerns a medical tubing assembly () comprising: finned medical tubing () formed from an elongate tubular member () disposed with one or more longitudinal fins (), a collar (), slidably mountable on the finned tubing (), equipped with a locking means and optionally one or more suture eyelets (), said locking means configured to provide a locking force against one or more of the longitudinal fins (). The invention allows securing of a medical tubing in situ that prevents slippage or damage to the tubing wall.

The balloon catheter comprises a catheter tube surrounded distally by an elongated inflatable balloon. Throughout the catheter tube is a longitudinal lumen for positioning a radioactive radiation emitter within the balloon. The catheter comprises a second lumen for directing inflation fluid into the balloon. Belt means creating a waist are mounted on the balloon to squeeze it down to nearly the diameter of the catheter thereby leaving a small passage for the inflation fluid. The belt means divide the balloon into sections to assure a close center fit of the catheter within the balloon.

The appliance comprises radioactive radiation means formed by a coiled filament of radioactive material a proximal part of which is formed by a coiled filament having a pitch larger than that of the coiled filament. Coiled filament is for meshing with thread formed at the distal end of a guidewire.

Medical appliances for the treatment of blood vessels by means of ionizing radiation

A system for intravascular ionizing radiation therapy including a radiation device and a guide wire having radiopaque markers to facilitate precise repositioning of the radiation source along the length of the treatment site. The radiopaque markers are separated by a distance L, which corresponds to the distance between the 50% dose points in the dose fall-off regions. This produces partial dose overlap when the radioactive source is positioned in tandem adjacent each radiopaque marker. Preferably, only the dose fall-off regions overlap thereby providing more uniform and complete radiation exposure along the length of the treatment site.

System and method for intravascular ionizing tandem radiation therapy

A prepared catheter for intraluminal treatment of a vessel section with ionizing radiation, which catheter has an elongate shaft with a proximal end and distal end as percutaneous transluminal access to the vessel section, an inflatable balloon at the distal end of the shaft, and inflation lumen which runs through the shaft and opens into the balloon, and a source of ionizing radiation which can be positioned in the balloon, and which catheter is filled with a gas for applying pressure to the balloon. In this way, only a comparatively small proportion of the ionizing radiation is absorbed and rendered ineffective as it passes through the gas, and the intended dose of radiation can be administered within a short treatment time. The inflation lumen preferably has, along the greater part of the length lying within the patient's body during treatment, a cross-sectional area having a value in mm,not greater than the balloon in mm,divided by 1200. In this way, a reduction in the overall profile of the catheter is achieved while at the same time retaining the desired deflation times for the balloon.
