Patent number: 10632281Abstract: A system and method for delivering a drug to a target site within a patient's body. The system and method include a steerable guide catheter and a drug delivery catheter. The steerable guide catheter has a first extension tube and a second extension tube that are joined together and form a shoulder. The delivery catheter has a distal docking segment and a proximal docking segment. The guide catheter is inserted into the patient's body, then the delivery catheter is inserted into the guide catheter. The distal docking segment engages the first extension tube, the proximal docking segment engages the second extension tube, and the shoulder limits the distance the delivery catheter can be inserted into the guide catheter. Also, once the delivery catheter is inserted it can be rotated to attach the helical tip to the target site. The guide catheter also includes a steering mechanism as well as a friction mechanism which controls the tension on the steering mechanism.Type: GrantFiled: April 21, 2014Date of Patent: April 28, 2020Assignee: BioCardia, Inc.Inventors: Daniel C. Rosenman, Peter A. Altman, Brian K. Hakim, Daniel J. Kayser, Robert E. Maston, Douglas McEtchin
