JET™ / Jacketed External Telemetry Blood Pressure
Jacketed External Telemetry

The JET Blood Pressure Add-On
Expand on your Jacketed External Telemetry (JET™) capabilities with the JET BP Add-On and acquire accurate, continuous blood pressure data from a minimally invasive implant. No other system provides comparable accuracy or power for hemodynamics studies.

JET BP Add-On
The JET Blood Pressure Add-On consists of a remote antenna receiver and electronics module that are interfaced directly to the JET device. Together these components receive a signal from a DSI pressure-only implant. The implant and receiver antenna should be as close as possible for optimal performance.

Implant
The DSI pressure-only implant is typically placed in the femoral or carotid artery to enable a direct blood pressure measurement via a simple, fast, and minimally invasive surgical procedure with a rapid recovery. Based on experience with canines and primates, the duration is 10 – 15 minutes from first incision to final suture. Implant sites are typically located within the optimal distance of a JET BP antenna that is housed inside a protective jacket.

Accurate and Continuous Data and Analysis
Accurate, continuous blood pressure data allows for determination of Systolic, Diastolic, and Mean pressures, along with Heart Rate and +/-dP/dt on a beat-to-beat basis – and you can look at the waveform morphology!

Histopathology
Due to the small size and simple surgery, histopathology concerns can be successfully mitigated. No significant histopathology was observed following implantation of up to 15 weeks.

Obtaining Blood Pressure via JET requires a minimally invasive implant; however, researchers seeking highly accurate and continuous blood pressure waveform data, will find other technologies just do not compare.

Non-Invasive Blood Pressure Cuff

  • Significantly less accurate
  • Non-continuous
  • Stress inducing
  • Typically non-ambulatory
  • Difficult to use in ambulatory implementations

Catheter via Vascular Access Port

  • Potential for infection
  • Requires significant maintenance
  • Use of heparin in port maintenance produces complications
  • Surgical procedure required

Pulse Transit Time

  • Indirect measure relying on multiple assumptions and complex calculations that although theoretically accurate have not been proven in practice
  • Non-continuous
  • Difficult to use in ambulatory implementations

High Density Oscillometry

  • Difficult to use in ambulatory implementations
  • Typically non-ambulatory

Crosstalk is possible when using JET Blood Pressure in a group-housing situation. However, the design of the system minimizes the possibility of crosstalk because the PA-C10-TOX implant has a short transmission range and the JET BP Antenna may be placed very close to the implant.
