Traditional fluid filled catheters for the measurement of pressure via telemetry are:
- Prone to movement artefacts and effects of gravity
- Susceptible to clotting
- Easily damaged or kinked
- Utilize a gel in the tip that requires replacing before each use
- Suffer from a relatively poor frequency response
Telemetry Research, in conjunction with Millar Instruments, has developed a fully implantable telemeter incorporating a novel micro-tip 2 Fr solid-state sensor.
This sensor is especially suited to the chronic measurement of LVP and RVP in small animals
Surgical Approach in the rat for LVP:
- Intubated and ventilated
- Trans-diaphragm approach via a midline abdominal incision
- Hole made in LV wall using 23G needle
- Catheter tip inserted into the LV
- Secured using tissue adhesive and/or suture
- Telemeter body placed in the peritoneal cavity
Chose your model:
- TRM54P Pressure only
- TRM54PB Pressure and Biopotential
- TRM54PP Dual Pressure
