Document Type and Number:
WIPO Patent Application WO2003013641
Kind Code:
A3
Abstract:
Disclosed is a device for delivering a therapeutic or diagnostic agent to an anatomic position, such as a heart. The device includes a flexible catheter having a proximal end and a distal end, a guide wire lumen that extends longitudinally through the catheter, and a delivery lumen that extends longitudinally at least partially through the catheter. The delivery lumen communicates with a side port adjacent a distal end of the catheter, through which side port a therapeutic or diagnostic agent may be delivered. The device also may include a guide wire, and the catheter may be advanced along the guide wire via the guide wire lumen. The device also may include a secondary catheter capable of sliding through the delivery lumen and capable of delivering a liquid, solid, or radiant agent to a desired anatomic location; thus, the secondary catheter may be considered a delivery catheter. The device may be used to deliver a therapeutic agent to a particular body location in a subject suffering a disease. In certain embodiments, the device may be used to deliver an ablative agent to the heart of a subject suffering hypertrophic cardiomyopathy.
