MYOtherm XP™
Cardioplegia Delivery System with Cortiva™ BioActive Surface
1. Description
The MYOtherm XP™ cardioplegia delivery system with Cortiva™ bioactive surface is designed to mix arterial
blood from an oxygenator with asanguineous cardioplegia solution in specific ratios, depending upon the system
chosen. The specifications provided by each standard system and their corresponding product designations are
presented below in Table 1. The patient delivery line is packaged separately to allow for ease of sterile transfer
to the operative field prior to connection to the delivery outlet of the cardioplegia system. A pressure monitoring
line, three-way stopcock, gauge protector, and a pressure relief line with pressure relief valve are preconnected.
Products coated with Cortiva bioactive surface include a "CB" prefix in the model number. Additional information
regarding Cortiva bioactive surface is available in Section 7.

2. Indications for use

The MYOtherm XP with Cortiva bioactive surface is a device intended for the mixing, warming/cooling and
delivery of oxygenated blood/cardioplegia solution in a predetermined ratio during routine cardiopulmonary
bypass (CPB) procedures up to 6 hours in duration. Blood/cardioplegia solution is delivered to the patient
through the cardioplegia delivery system and appropriate cannula by the operation of a single occlusive roller
pump.
3. Contraindications
Use the device only as indicated.
4. Warnings
Read all warnings, precautions, and instructions for use carefully prior to use. Failure to read and follow all
instructions, or failure to observe all stated warnings, could cause serious injury or death to the patient.
■
Only persons thoroughly trained in CPB procedures should use this device. Operation of each device
requires constant supervision by qualified personnel for patient safety. Perfusion must be carefully and
constantly monitored.
■
Each device is intended for single use only. Do not reuse or resterilize. Sterilized using ethylene oxide.
■
