Trans-Septal Left Ventricular Pressure Measurement
First Claim
1. A pressure sensing device comprising:
- a body portion having transducing electronics within a housing that is shaped about a longitudinal axis, the housing having a coating thereon that promotes tissue growth to anchor the housing within a ventricular septum;
a pressure transmitting port located at a distal longitudinal end of the body portion such that a ventricle pressure being sensed is transmitted through the port and to the transducing electronics when the body portion is anchored in the ventricular septum; and
an electrical lead connected to the transducing electronics and exiting from a proximal longitudinal end of the body portion.

Abstract
A pressure sensing device includes a body portion, a pressure transmitting port, and an electrical lead. The body portion includes transducing electronics within a housing that is shaped about a longitudinal axis. The housing has a coating thereon that promotes tissue growth to anchor the housing within a ventricular septum. The pressure transmitting port is located at a distal longitudinal end of the body portion such that a ventricle pressure being sensed is transmitted through the port and to the transducing electronics when the body portion is anchored in the ventricular septum. The electrical lead is connected to the transducing electronics and exits from a proximal longitudinal end of the body portion.

6. A method of measuring pressure in a left ventricle, the method comprising:
-
inserting a pressure sensing device through a ventricular septum to sense a pressure in a left ventricle, the pressure sensing device including; (a) a body portion having transducing electronics within a housing that is shaped about a longitudinal axis, the housing having a coating thereon that promotes tissue growth to anchor the housing within the ventricular septum, (b) a pressure transmitting port located at a distal longitudinal end of the body portion such that a ventricle pressure being sensed is transmitted through the port and to the transducing electronics when the body portion is anchored in the ventricular septum, and (c) an electrical lead connected to the transducing electronics and exiting from a proximal longitudinal end of the body portion; wherein inserting the pressure sensing device includes positioning the body portion in the ventricular septum and the port in the left ventricle. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
