Rat Telemeters

TR50B, TR50BB, TRM54P, TRM54PB, TRM54PP, TRM56SP, TR57Y

Configurations


Biopotential Telemeter (ECG, EEG, EMG)

TR50B

The Rat Biopotential Telemeter measures the biopotential difference between the two electrode leads. These leads can be placed to measure a single biopotential signal such as ECG, EEG, or EMG. Weighs ~12 g (7 cm3) and includes 25 cm long biopotential leads.


Dual Biopotential Telemeter (ECG, EEG and/or EMG)

TR50BB

The Dual Rat Biopotential Telemeter measures the biopotential difference between each pair of electrode leads. The leads can be used to measure two biopotential signals such as ECG, EMG and/or EEG. Weighs ~12 g (7 cm3) and includes 25 cm long biopotential leads.


Dual Pressure Telemeter

TRM54PP

The Rat Dual Pressure Telemeter measures two high-fidelity pressures using solid-state Millar Mikro-TipTM sensors. Pressure is measured directly at the tip of each pressure catheter (2Fr in diameter, 9 cm long (15 cm & 25 cm options available)) and the telemeter can be used to measure arterial, venous, ventricular and/or intracranial pressures (25 cm catheter option).


Pressure Biopotential Telemeter

TRM54PB

The Rat Pressure Biopotential Telemeter combines measurement of high-fidelity pressure using a solid-state Millar Mikro-TipTM sensor with a single biopotential signal (e.g. ECG, EEG or EMG). Pressure is measured directly at the tip of the pressure catheter (2Fr in diameter, 9 cm long (15 cm & 25 cm options available)) and the telemeter can be used to measure arterial, venous, ventricular or intracranial pressure (25 cm catheter required). The biopotential signal measures the potential difference between the pair of 25 cm coiled electrode leads. The telemeter weighs approximately 12g.


Pressure Telemeter

TRM54P

The Rat Pressure Telemeter measures high fidelity pressure using a solid-state Millar Mikro-TipTM sensor. Pressure is measured directly at the tip of the catheter (2Fr in diameter, 9 cm long (15 cm & 25 cm options available)) and the telemeter can be used to measure arterial, venous, ventricular or intracranial pressure (25 cm catheter required). The telemeter weighs approximately 12g.


SNA and Pressure Telemeter

TRM56SP

The Rat Sympathetic Nerve Activity (SNA) and Pressure Telemeter is the only commercially available telemetry device that allows concurrent measurement of SNA and pressure. the telemeter weighs approximately 12 g with a Millar solid state pressure sensor (2Fr in diameter, 9 cm long (15 cm & 25 cm options available)) and multi-stranded SNA lead wires (25 cm long). The telemeter samples the pressure and SNA signals at 2 kHz with an SNA input range of ±60 µV.


Tissue Oxygen Telemeter

TR57Y

The Rat Tissue Oxygen Telemeter is an implantable potentiostat with a carbon paste electrode specifically configured for measuring tissue (e.g. brain, kidney) oxygen concentration in freely moving rats >175 g. The telemeter can be easily cleaned and sterilized for reuse after attachment of new electrodes. Ideal option for cohousing option in order to measure tissue oxygen measurement with other signals by placing two telemeters in one rat.

Benefits of Kaha Rat Telemeters

  • Powered by the SmartPad using patented wireless inductive technology, providing higher sampling rates (2 kHz) and temporal resolution for superior data quality.
  • Supports unique signal acquisition including tissue oxygen and SNA.
  • Pressure sensors incorporate Millar Mikro-TipTM catheter technology for unparalleled signal quality in a telemetry system.
  • Data transmission range up to 5 meters with battery backup and in vivo recharging allows for experimental scenarios where a greater range of movement is required e.g. water maze behavioural studies.
  • Cohousing feature enables two rats in the same cage or single rat (>350g) implanted with two telemeters.
  • All implants provide improved animal welfare by allowing the subject to move freely within the cage, a cohousing option to reduce stress of single housing, and being fully software controlled to reduce handling/impact of stress. Find out more about the benefits of telemetry.

Simple and Customizable Telemetry System Setup

Configure a Kaha Sciences Rat telemetry system to meet your exact research needs. A typical telemetry setup requires one telemeter of your choice and one SmartPad per animal. Each laboratory will just require one Configurator in order to configure all your Kaha equipment.

  1. Select and pair transmission frequencies between SmartPads and their Telemeters using Configurator.
  2. Surgically implant the Telemeter.
  3. Connect the SmartPad to a PowerLab via the BNC analog outputs.

You are then ready to analyze your data using LabChart 8 or LabChart Lightning.

Cohousing

An additional advantage of a Kaha Sciences Rat Telemetry System is the cohousing feature:

  • Allows two rats (>175g), each implanted with one telemeter, to be housed together in a single cage to reduce stress of single housing and lab space requirements, or
  • Two telemeters to be implanted in one animal (>350g), allowing the measurement of up to four physiological signals (e.g. Oxygen + dual pressure or oxygen + SNA with pressure)

With Cohousing, the system continues to regulate the power supplied to both telemeters seamlessly while collecting continuous data with the expected accuracy and quality. Cohousing still requires one SmartPad per telemeter, as well as a Configurator System for the laboratory.

Existing systems can be upgraded to use the Cohousing feature without the need to purchase additional hardware. Cohousing also requires ConfigSoft software version 3.0 or later.
