Abstract:
Implantable devices for continuously monitoring vascular lumen dimensions, in particular in the inferior vena cava (IVC) for determining heart failure status of a patient. Related therapy systems as well as monitoring and therapy methods are also disclosed. Devices include active or passive marker elements placed in contact with, adhered to or injected into the vessel wall to generate or reflect signals from which lumen diameter may be determined. Disclosed devices may be fully implantable and self-contained including capabilities for wirelessly communication monitored parameters.

Claim (Index 29):
A method of monitoring vascular fluid volume of a patient, comprising:\n positioning a delivery catheter containing an intravascular device at a monitoring location within a vascular lumen of the patient's vena cava, said intravascular device being configured to allow natural collapse and distension of the vena cava in response to changes in vascular fluid volume; deploying the intravascular device within the vascular lumen by releasing the intravascular device from the delivery catheter so that it self-expands to engage the lumen wall at the monitoring location, the intravascular device thereafter resiliently changing shape or dimension in response to the natural collapse and distension of the vena cava; positioning a detecting system outside the patient's body; energizing the intravascular device to produce a measurement signal correlated with a change in diameter or area of the vascular lumen; and wirelessly receiving at the detecting system the measurement signal from the intravascular device.
