Pulsatile Pumps

From our expertise and years of modeling cardiovascular fluid dynamics in both academia and industry, BDC Laboratories has developed a number of pulsatile pump systems: PD-1100, PD-0750 and PD-0500. The PD-1100 is a highly repeatable and controllable pulsatile pump and is the fluid driver for BDC’s HDT-500 pulse duplicator system. The PD-1100 is an excellent resource to drive simulated cardiovascular flow networks for device validation testing or research applications such as PIV. In these cardiovascular simulation networks, the PD-1100 acts as the pumping heart; therefore with the PD-1100 and the appropriate components, the local hemodynamics of any vascular bed can be simulated. BDC’s Statys™ PD control and monitoring software package comes with the system purchase and provides a means to completely control of the excitation waveform as well as a monitor the simulated flow network parameters such as pressure, flow and temperature.

In contrast, the PD-0750 and PD-0500 systems were developed as a simplified, portable pulse duplicator / pulsatile pump systems that could be easily transported and operational within minutes. The PD-0750 was designed for cardiac heart valve technologies and the PD-0500 is for endovascular and vascular technologies. These pumping systems are comprehensive and include an integrated heated fluid reservoir, compliance chamber and adjustable resistance. Furthermore both systems are designed to easily couple with any existing cardiac / vascular model or BDC can design and build a silicone or rigid model based on your specifications and needs. When it comes to on-site surgeon training, market research, or product demonstrations, the PD-0750 and PD-0500 systems are the optimal solution.

  • Highly versatile and adaptable for any general cardiovascular, stent, stent graft or heart valve application
  • Pulsatile Pump Head: The Pulsatile Pump Head enables the PD-1100 to function as a positive displacement pulsatile pump. Featuring a barbed inflow and outflow port, both with one-way valves, and self-priming performance, the Pulsatile Pump Head allows convenient inclusion into a fluid loop.
  • Heating Reservoir: The Heating Reservoir allows the user to control the temperature of the system fluid and provides a convenient system filling location. The Heating Reservoir features a heating element, inflow and outflow ports, a drain valve, temperature probe and safety switch.
  • Fluid Isolation Module: The Fluid Isolation Module serves to isolate the test solution from the pump fluid. This allows the user to run particles in the test solution without damaging the PD-1100 drive seals, as well as maintain the sterility of the test solution without needing to treat the PD-1100 driver assembly.
  • Compliance Chamber: The Compliance Chamber acts as a dampening element that allows the operator to tune the pressure pulse. The Chamber mimics the elasticity of the arteries in the vascular bed.
  • Hemodynamic Flow Conditioner: The Hemodynamic Flow Conditioner is an all-in-one addition to the PD-1100 that emulates the vascular bed. The Conditioner has integrated directional valves, a fluid reservoir, a compliance chamber, a heater and a resistance element.
  • Heart Function Emulator, HFE: The Heart Function Emulator is connected to the pulsatile flow pump and serves to emulate the contractile and resistive conditions of the heart, resulting in a more clinically relevant flow and pressure source for cardiac applications. The HFE consists of an impedance element and compliance chambers. The compliance volumes can be adjusted to tune the shape of the flow waveforms.
  • Diastolic Pressure Control: The Diastolic Pressure Control (patent pending) replaces the standard Pulsatile Pump Head outflow assembly with a tunable element that serves to control a cardiac flow network’s diastolic filling pressure, resulting in a more clinically relevant pressure environment for prosthetic valve applications.
  • Small Piston: The Small Piston optimizes the PD-1100 for low flow applications up to 2 L/min.
  • Large Piston: The Large Piston optimizes the PD-1100 for high flow applications up to 25 L/min.
  • Administrator Control Module: The Administrator Control Module provides a means to restrict access via a password to critical system software parameters.
  • Hydrodynamic Testing Module: The Hydrodynamic Testing Module enables the user to perform real time analysis of valve functional performance based on the ISO 5840 requirements. The data is segregated into individual pulses and then analyzed based upon cursors indicating key events in the cardiac cycle.
  • Production QA Module: The optional Production QA Module provides a data review and capture tool for functional testing of prosthetic heart valves. The test operator is presented with critical performance information in a go/no-go color coded format. Once all parameters are within specifications set by a software administrator, the user will be allowed to collect data. The results are displayed and written to an external data file.
  • Downsampling Data Logger: The Downsampling Data Logger allows the user to reduce the sampling rate and create a more manageable data file. This is advantageous when recording data at a high rate (e.g., 1 KHz) is not desired or when an experiment is carried out over a long period.
  • Multi-Mode Waveform Controller: The Multi-Mode Waveform Controller allows the user to easily switch between up to three user pre-defined run conditions (e.g., normal to an atrial fibrillation mode). When the operating mode is changed, the pump automatically changes from the current run condition to immediately start another predefined run condition.
  • Analog Retransmission Module: The Analog Retransmission Module feature allows the user to retransmit two system signals to a secondary measurement system. The user can choose the desired retransmission signals and the associated output scaling.
  • Bypass Mode: The bypass mode allows the user to transition from the running flow and beat rate to a Cardiopulmonary bypass condition (i.e. stopped-heart) by decreasing the flow rate over a given period of time.
  • Trigger Start/Stop: The Trigger Start/Stop allows the PD-1100 to start running based upon a digital input signal. After receiving the digital input signal, the system can wait a specified delay period before initiating.
  • Autonomous Run Module: The Autonomous Run Module allows the user to conduct extended duration tests in a controlled, monitored and documented environment when the operator is not attending the running system (e.g. the PD-1100 system will continue to run throughout the night). The package includes: historical plotting, alarm safety features and statistical data logging. The down sampling data logger option is also included with this package.
  • ECG Signal Module: When running the PD-1100 in conjunction with clinical equipment designed to operate with an ECG signal, the ECG Signal Module generates an actual ECG waveform to interface with the clinical equipment.
The Statys™ test system control and data acquisition software platform enables complete system control and comprehensive data acquisition to facilitate detailed control of BDC’s test system while maximizing transparency and data logging of the test article’s response. Statys software provides an intuitive and easy to use interface to facilitate a short learning-curve to master BDC’s test systems. Different version of the Statys software were specifically designed for each model of BDC’s testing equipment to meet the unique applications and functions of the equipment and to provide for optimize functions of the system control and data acquisition system software.
