Medical devices with magnetic resonance visibility enhancing material

摘要

The present invention relates to an elongated medical device for intralumenal manipulation during a process of magnetic resonance imaging. The device includes an elongated body. An extrusion material is integrated with the elongated body and includes a hydrophilic polymer that incorporates a substance having a plurality of paramagnetic ions. The extrusion material is configured to enhance magnetic resonance visibility during said process of magnetic resonance imaging.
