Vascular blood pressure monitoring system with transdermal catheter and telemetry capability
First Claim
1. A system for monitoring intravascular pressure of a patient, comprising:
- a pressure sensor and catheter assembly including a pressure sensor portion and a transdermal catheter portion, the transdermal catheter portion having a fluid filled lumen and a distal barrier;
a lead connected to the pressure sensor portion;
a transmitter unit releasably connected to the lead, the transmitter unit transmitting pressure data received from the pressure sensor via the lead;
a connector for releasable connection to the patient'"'"'s body or clothing; and
a receiver unit for receiving pressure data from the transmitter unit.

Abstract
Systems and methods for monitoring intravascular pressure of a patient. The system includes a pressure sensor and catheter assembly having a pressure sensor portion and a transdermal catheter portion. The transdermal catheter portion has a fluid filled lumen and a distal barrier to maintain patency. A transmitter unit may be connected to the pressure sensor portion via a lead. The transmitter unit transmits pressure data to a remote receiver unit that may communicate (directly or indirectly) with a cable management device, a data acquisition device, a monitoring instrument, a computer, a modem, a telecommunication line, a network, etc. In addition, the system may include means to correct for pressure variations due to any difference in elevation between the sensor assembly and the heart.

7. A method for monitoring intravascular pressure of a patient, comprising:
-
providing a pressure sensor and catheter assembly including a pressure sensor portion and a transdermal catheter portion, the transdermal catheter portion having proximal end, a distal end, and a fluid filled lumen with a distal barrier;
inserting the transdermal catheter portion through the patient'"'"'s skin and into a vascular lumen such that the distal end resides in the vascular lumen and the proximal end resides outside the skin;
providing a lead connected to the pressure sensor portion;
providing a transmitter unit having a means for connection to the patient'"'"'s body or clothing;
releasably connecting the lead to the transmitter unit to receive pressure data from the pressure sensor portion;
connecting the transmitter unit to the patient'"'"'s body or clothing;
providing a remote receiver unit; and
transmitting pressure data from the transmitter unit to the remote receiver unit. - View Dependent Claims (8, 9, 10, 11, 12, 13)
