Abstract
Apparatus with a pneumatic or hydraulic or mechanical therapeutic catheter. The therapy energy required to treat internal vessels of the patient is transferred by the same fluid or the same elements from the proximal end section to the distal end section of the catheter that transfer information from the distal end section to the proximal end section of the catheter. The information provides understanding of the state of the vessel and how the therapy fluid of the therapy element of the catheter acts on the vessel.

11. A therapeutic catheter, comprising:
-
an elongate shaft having a proximal end section, a distal end section, and a lumen extending from the proximal end section of the elongate shaft to the distal end section of the elongate shaft;
an expandable balloon adapted to perform a therapeutic treatment on a patient, the expandable balloon coupled to the distal end section of the elongate shaft such that the expandable balloon is in fluid communication with the lumen of the elongate shaft;
means for providing inflation fluid to the expandable balloon;
means for determining the fluid flow rate of inflation fluid within the expandable balloon; and
means for providing inflation fluid flow rate information to an operator. - View Dependent Claims (13, 14, 15, 16, 17)
