Additions to the IH-SR Core System for species-specific Langendorff Only or Langendorff Working Heart-Ready functional units

An IH-SR Langendorff functional unit requires the addition of core options to the selected core system (either 73-4343 or 73-4344). Specifically, the core system requires the addition of a selection of one of the perfusion pressure controllers (SCP or STARLING-IHSR) and one of the species-specific options indicated in the table below:

 Langendorff Only Configuration
 (Add these core options to 73-4343 or 73-4344)
 Langendorff Working Heart-Ready Configuration
(Add these core options to 73-4343 or 73-4344)
 Species Specific Addition (choose one or both)
• 73-4019 IHSR-MOUSE
• 73-4020 IHSR-RGP

 Species Specific Addition (choose one or both)
• 73-4019 IHSR-MOUSE
• 73-4020 IHSR-RGP

 Constant Pressure/Flow Controller (required)
73-2806 SCP PLUGSYS Servo Controller Module 

 Perfusion Pressure Control (required)*
• 73-4346 STARLING-IHSR Starling Pressure Controller

The core options selected depend on:

  1. If you want a Langendorff Only configuration or a Working Heart-Ready Langendorff configuration. (If you expect to upgrade from Langendorff to Working Heart in the future, we recommend you start with the working heart-ready configuration.)
  2. The species to be studied, i.e., mouse, rat or guinea pig

*Additionally requires a species-specific direct flow measurement option.


Pressure Controller Options

SCP Servo Controller for Perfusion (73-2806)

This constant pressure/flow controller perfuses a heart in constant pressure mode. Required for Langendorff Only configuration.

  • Allows operation in constant pressure or constant flow with simple switch
  • Provides accurate control of perfusion pressure or flow, even at very low flow rates
  • Flexible perfusion circuit setup adjustes to suit individual perfusion conditions

Additional measured signals/calculated parameters:

  • Indirect coronary flow measurement
  • Calculation of coronary resistance

Additional items required:

  • PC-based data acquisition system

 

STARLING-IHSR Perfusion Pressure Controller with Starling Resistor (73-4346)

This perfusion pressure controller with Starling resistor provides constant pressure perfusion of the heart and the ability to calculate coronary flow. Required for Langendorff Working Heart-Ready configuration.

  • Uses Teflon membrane flow resistor, manometer and pressure syringe to create a pressure-controlled valve in the aortic block
  • Mechanical device that does not provide flow information and does not alter the pump flow rate
    • Flow rate is set high on the pump and only the flow that generates the set perfusion pressure is delivered to the heart while the remainder exits via the valve and returns to the reservoir.
  • Must choose direct coronary flow measurement to capture coronary flow data

Additional measured signal/calculated parameters:

  • Coronary flow data

 Includes:

  • Aortic Block Base Unit with Flange-Mounted Adjustable Flow Resistance
  • Pressure Syringe with Mounting Bracket
  • Manometer

Additional items required:

  • TTFM-2 and appropriate flow probes for direct flow measurement
  • PC-based data acquisition system
  • Pump, transducer and amplifiers for additional measurements
