1 Description

The Bio-Pump centrifugal blood pump with or without Cortiva bioactive surface
has been designed to utilize the constrained forced-vortex pumping principle.
In action, blood is allowed to pass through a vortex created by the rotation of a
series of smooth-surfaced rotating cones. Energy is transferred from the cones
to the blood in the form of pressure and velocity as the blood is gently
accelerated toward the outlet of the blood pump. The Bio-Pump blood pump is
fabricated from sturdy, thromboresistant, biocompatible acrylics which are
mounted on precision bearings for dependable operation. The non-occlusive
hemodynamic design of the blood pump promotes laminar flow, allowing for
improved blood handling capabilities and decreasing trauma which may be
associated with extracorporeal circulatory support during cardiopulmonary
bypass.

The blood pump couples to a safety-locked magnetic drive unit called the
external drive motor (Model 540T), which is controlled by a Medtronic
Bio-Console pump speed controller. The external drive motor and
Bio-Console pump speed controller serve as the hardware components of the
Medtronic extracorporeal blood delivery system.

The blood pumps have been sterilized using ethylene oxide.
Products coated with Cortiva bioactive surface include a “CB” prefix in the

model number. Additional information regarding Cortiva bioactive surface is
available in Chapter 7.

2 Indications for use

The Medtronic Bio-Pump centrifugal blood pump is indicated for use only with
the Medtronic Bio-Console pump speed controller to pump blood through the
extracorporeal bypass circuit for extracorporeal circulatory support for periods
appropriate to cardiopulmonary bypass procedures (up to 6 hours).

3 Contraindications

The Medtronic centrifugal blood pumping system is contraindicated as a
cardiotomy suction device.

Use the device only as indicated.

4 Adverse effects

The following known adverse effects are associated with the use of the
product: blood loss, coagulopathy, death, embolism, excessive blood
component activation or thrombogenicity, exsanguination, hemolysis,

English

hemolytic anemia, infection, ischemia, neurological dysfunction, and organ
dysfunction.

5 Warnings

Read all warnings, precautions, and instructions for use carefully before use.
Failure to read and follow all instructions or failure to observe all stated
warnings could cause serious injury or death to the patient.

• The blood pump has not been qualified through in vitro, in vivo, or clinical
studies for long-term use (longer than 6 hours) as a bridge-to-transplant or
for pending recovery of the natural heart.

• Possible side effects include, but are not limited to, infections, mechanical
failure, hemolysis, and thromboembolic phenomena. These are potential
side effects with all extracorporeal blood systems.

• Ensure that the blood pump and the circuit have been debubbled and
primed properly before beginning bypass to minimize the risk of air
reaching the patient. The use of an arterial filter is recommended.

• Massive air entry into the centrifugal blood pump deprimes the pump and
stops blood flow. Stop the pump and remove air before resuming
circulation.

• Do not use alcohol or alcohol-based solutions on any surface of the blood
pump.

• To prevent retrograde blood flow when the blood pump outlet tubing is
open, establish and maintain a minimum pump speed that overcomes line
and patient resistance. Failure to do this could allow retrograde flow and
exsanguinate the patient.

• Clamp the arterial lines when the blood pump is at rest to prevent
retrograde flow.

• The blood pump is designed to be operated only with the Medtronic
Bio-Console pump speed controller. There is no safety or performance
data known to Medtronic which establishes compatibility of any other
manufacturer’s devices or components to the Medtronic system. Run the
blood pump only on a properly maintained Bio-Console pump speed
controller.

• Evaluate potential risk to the patient before changing the blood pump.

• Frequent patient and device monitoring is recommended; do not leave the
centrifugal blood pump unattended while in use. Monitor the flow rate
carefully for signs of occlusion throughout the circuit.

• Do not operate the centrifugal blood pump for more than 30 s in the
absence of flow. The temperature within the pump could rise and
increased cellular damage may result.

7

English

• The centrifugal blood pump must be handled using aseptic technique.

• Do not operate the blood pump with its inlet clamped. This will generate
negative pressure in the blood pump and could cause air bubbles to form
in the blood.

6 Precautions

• This device should be used only by clinicians thoroughly trained in
extracorporeal circulation procedures.

• Do not forcefully strike or drop the centrifugal blood pump. Shock may
cause damage to the device, which may cause the device to malfunction.

• The fluid pathway of the centrifugal blood pump is sterile and
nonpyrogenic. Inspect the device and package carefully before use. Do
not use if the unit package or the product has been damaged or soiled, or
if caps are not in place.

• This device was designed for single patient use only. Do not reuse,
reprocess, or resterilize this product. Reuse, reprocessing, or
resterilization may compromise the structural integrity of the device and
create a risk of contamination of the device, which could result in patient
injury, illness, or death.

• Attach tubing in a manner that prevents kinks or restrictions that may alter
flow.

• Do not operate the centrifugal blood pump unprimed; damage to the
internal components will occur.

• Do not use the blood pump if dropped. Shock may cause damage to the
device, which may cause device malfunction.

• Do not use excessive force to install tubing on the pump because damage
to the pump might occur.

• Take care to prevent damage to connectors when repositioning or
attaching tubing.

• Always have a spare blood pump near and backup equipment available
with appropriate protocol for change out.

• Do not place the centrifugal blood pump near items adversely affected by
magnetic fields.

• Follow a strict anticoagulation protocol and routinely monitor
anticoagulation during all procedures.

• It is the user’s responsibility to dispose of the devices in accordance with
local regulations and hospital procedures.

7 Information for products with Cortiva bioactive surface

The primary blood-contacting surfaces of the product are coated with Cortiva
bioactive surface. This coated surface enhances blood compatibility and
provides a blood-contacting surface that is thromboresistant. Cortiva bioactive
surface contains nonleaching heparin derived from porcine intestinal
mucosa1.

Caution: Product coated with Cortiva bioactive surface is intended for single
use only. Resterilization may adversely affect the Cortiva bioactive surface.

Caution: Follow a strict anticoagulation protocol and routinely monitor
anticoagulation during all procedures.

8 Recommended priming procedures

1. Using accepted aseptic technique, attach the appropriate tubing to the
inlet and the outlet of the blood pump.

Note: Applying a sterile saline solution to the inlet and outlet connectors
may aid tubing attachment.

2. Where practical, flush the circuit and the blood pump with CO2 (from filter
or reservoir bag).

3. Using gravity, fill the blood pump with priming solution to a point beyond
the flow probe and clamp. Eliminate air from the device by “walking” the air
out of the outlet.

Caution: Do not hit or strike the blood pump with hands or instruments.
Shock may cause damage to the device, which may cause device
malfunction.

Warning: Ensure that the blood pump and the circuit have been
debubbled and primed properly before initiating bypass to minimize the
risk of air reaching the patient. The use of an arterial filter is
recommended.

Warning: Massive air entry into the blood pump will cause it to deprime
and blood flow to stop. Stop the blood pump and remove the air before
resuming circulation.

4. With the outlet clamped, turn the Bio-Console pump speed controller
power “ON.”

5. Zero (gain and balance) the flow probe according to the Bio-Console
Operator and Reference Manual.

6. With the outlet still clamped, turn the RPMs of the Bio-Console pump
speed controller to maximum RPM for 30 s. This delivers maximum

pressure within the blood pump, which aids in ensuring its integrity.
Observe the blood pump for leakage or other anomalies.

Warning: Do not operate the blood pump for more than 30 s in the
absence of flow. The temperature within the blood pump will rise and
increased cellular damage may result.

7. Bring the RPMs to zero and recheck the integrity of the blood pump.
Warning: If leaks or other anomalies are found, remove the blood pump

and replace with a new, sterile blood pump, repeating the above steps to
prime.

8. If no anomalies are noted, continue priming the circuit.

9. Verify all connections and the integrity and flow of the circuit before use.
Warning: Do not operate the blood pump with its inlet clamped. This will

generate negative pressure in the blood pump and could cause air
bubbles to form in the blood.
