VASCULAR BLOOD PRESSURE MONITORING SYSTEM WITH TRANSDERMAL CATHETER AND TELEMETRY CAPABILITY

摘要

Systems and methods for monitoring intravascular pressure of a patient. The system includes a pressure sensor and catheter assembly (100) having a pressure sensor portion (130) and a transdermal catheter portion (110). The transdermal catheter portion (110) has a fluid filled lumen (112) and a distal barrier (116) to maintain patency. A transmitter unit (200) may be connected to the pressure sensor portion (130) via a lead (300). The transmitter unit (200) transmits pressure data to a remote receiver unit (400) 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.
