How Magnetically Directed and Manually Operated Catheters Differ

Magnetically directed catheters can reach locations that prove challenging with manually operated catheters.

Listen to Dr. J. David Burkhardt’s (St. David’s Medical Center, Austin, TX) brief descriptions of this concept.

Tissue/tip contact is as important as catheter reach. Magnetically directed catheters’ soft flexible shafts minimize the occurrences of both intermittent and sliding tissue/tip contact.
