RADIATION DIAGNOSTIC DEVICES AND METHODS

摘要

Radiation diagnosis devices, systems and methods are in general catheter form and include at least one diagnostic balloon that provides at least one diagnosis function and assists in placement of at least one radiation detector at a desired diagnosis location within an existing body cavity or at a percutaneous site. Data collected by the detector that is positioned as determined by the medical professional allows the medical professional to monitor radiation levels, either residual from a prior radiation treatment, during a brachytherapy treatment at the diagnostic catheter insertion site or in adjoining site, or during externally administered radiation.

主权项

1. A diagnostic catheter, comprising:
a catheter body that is sized, shaped and adapted to not deform under pressure encountered during passage from an insertion location to a target location within a subject of radiation treatment at the target location, the catheter body having an outside surface; a diagnostic balloon affixed to the catheter body, the diagnostic balloon having a proximal end portion, a distal end portion, an inner surface and an outer surface and a wall thickness between the surfaces; at least one detector that collects data on radiation, the detector being movable with respect to the balloon, the balloon having sufficient axial strength and radial extendability to cooperate in adjusting positioning of the detector with respect to the target location; a hyperthermia component that delivers hyperthermia treatment to the balloon; and the data collected by the detector monitors radiation recognized by the detector at the target location, which data is collected for further processing.
