Patent Images
1. A lead configured for measuring pressure in a heart comprising:
- a lead body having a proximal portion and a distal portion;
a connector assembly at the proximal portion of the lead body, the connector assembly to couple with an implantable cardiac device having circuitry that process signals to determine cardiac pressure;
an adjustable attachment structure attached to the distal portion of the lead body and adapted to attach the lead body to a heart wall through which the lead body passes by adjusting to a thickness of the heart wall;
a tensile member coupled to the adjustable attachment structure, wherein longitudinal movement of the tensile member slidingly moves the adjustable attachment structure relative to the lead body in a longitudinal direction; and
at least one pressure sensor attached to the lead body to measure pressure at a distal side of the heart wall.

Abstract
An apparatus for and method of measuring pressure through a septum in a patient'"'"'s heart is disclosed. A lead inserted into the right side of a heart is routed through the septum to gain access to the left side of the heart. The lead includes an attachment structure that secures the lead to one or both of the septal walls. The attachment structure may include at least one protruding tine, membrane, inflatable balloon, involuted spiral or J-lead that engage one or more sides of the septum. The lead also includes one or more sensors for measuring cardiac pressure on the left side of the heart and, as necessary, the right side of the heart.
