Inside-Out access strategy using new trans-vascular catheter approach

Abstract

Image guided minimal invasive treatment can have large benefits for patient recovery and is lowering hospitalisation costs. But an access path, minimizing patient’s risk, is needed to reach the target structure inside of the body. Beside the use of natural orifices like oral, vaginal or anal cavities, a percutaneous puncture is common to enter the body. Also an interstitial path can be selected but if the pathological structure is situated in the deep, a long accesses path is required. Thereby the risk of additional damage and affecting organ functionality is increased. A possible option to come closer to the target structure with less organ damage is by using the vascular system. Entering the vessel from an uncritical point, the vasculature can be used as “highway” to the target structures. For the treatment of these nearby structures, the vessel has to be punctured and occluded afterwards by a save procedure. We propose an Inside-Out access strategy using a new trans-vascular catheter approach.
