Abstract: An intravascular safety guidewire including an elongated main shaft, a distal terminus extending from the elongated main shaft, and an anchor rotatably connected to the distal terminus. In use, a needle is inserted into a patient's vein, then the intravascular safety guidewire is placed through the needle and into the vein, the needle is then removed over the intravascular safety guidewire, then a venous catheter is exchanged over the intravascular safety guidewire following serial dilatation using the Seldinger technique. Tubes such as dilators and catheters can then be placed over the intravascular safety guidewire and the intravascular safety guidewire ultimately removed. Currently complications can arise if a guidewire becomes retained inside a patient during an endovascular procedure, which is associated with high morbidity and mortality rates. The instant intravascular safety guidewire with its rotatable anchor reduces the likelihood of this complication.

Abstract: The present invention relates to the field of medical therapy of lesions detrimental to a body. The system is capable of treatment with a non-invasive, ionizing kV energy radiation source. Locally focused energy can be used to definitively treat, or as an adjuvant to enhance immune modulators, to eliminate tumors. Distributed external beam entry points produce a significant advantageous dose profile at depth as intersecting beams accumulate in a narrow focus to treat a selected volume. Targeted disease may have enhanced sensitivity to the radiation by taking up an ionizing-radiation, treatment-localizing agent. This increases the effectiveness of an energy dose in the lesion. The pattern of beam output is effectively directed towards a desired location and kV x-rays traveling towards undesired locations, such as healthy tissue, are quenched. Targeting a lesion within the body with volumetrically discrete energy dose deposition can beneficially impact harmful lesions.
