Patent ID: 8057399

Claim:
An implantable sensor assembly configured for delivery through a delivery catheter, the sensor assembly comprising: an implantable sensor; an anchor coupled to the sensor and adapted to assume a collapsed configuration within the delivery catheter and an expanded configuration external to the delivery catheter, the anchor including: a proximal hub portion; an intermediate anchor portion hingedly coupled to and extending distally and radially from the hub portion, the intermediate portion configured to assume a generally oblique angle with respect to the hub portion when the anchor is in the expanded configuration; and a distal anchor portion extending distally from the intermediate portion and adapted to engage an inner surface of a vessel when the anchor is in the expanded configuration; wherein the intermediate portion is configured to allow the anchor to be retracted within the delivery catheter and to assume the collapsed configuration after assuming the expanded configuration; and wherein, in the expanded configuration, the implantable sensor and proximal hub portion are radially offset from a radial center of the anchor such that the sensor is positioned at or proximate a periphery of the distal anchor portion.
