Abstract:
A catheter system for the delivery of a therapeutic or diagnostic agent, comprising:a) a first elongated delivery catheter which has proximal and distal ends, a port in the distal end, an inner lumen extending therein to and in fluid communication with the port in the distal end, a relatively straight main shaft section and a shaped distal shaft section having at least one segment forming an angle with respect to a proximally adjacent portion of the main shaft section;b) a second elongated delivery catheter which is slidably and rotatably disposed within the inner lumen of the first delivery catheter, which is longer than the first delivery catheter and which has proximal and distal ends, a port in the distal end, an inner lumen, an elongated main shaft section at least a portion of which is substantially alignable with a discharge axis of the first delivery catheter and a shaped distal shaft section at least a portion of which is substantially alignable with the discharge axis of the first delivery catheter and which is configured to have a discharge axis at an angle with respect to a portion of the main shaft section thereof aligned with the discharge axis of the first delivery catheter; andc) a substance delivery member which is slidably disposed within the second delivery catheter, which has a distal extremity configured for intracorporeal delivery of a diagnostic or therapeutic substance into a patient's tissue.
