Brief Summary of Safety Information for TandemHeart® Transseptal Cannula Set

(Commercial, August 2020)

  1. INDICATIONS FOR USE/INTENDED USE

The Transseptal Cannula Set is intended for transseptal catheterization of the left atrium via the femoral vein for the purpose of providing a means for temporary (six hours or less) left ventricular bypass when connected to the TandemHeart extracorporeal blood pump which returns blood to the patient via the femoral artery or other appropriate site.

  1. CONTRAINDICATIONS

The Transseptal Cannula Set should not be used when any anatomical, medical, or physiological impairment may contraindicate the use of a femoral access procedure or transseptal access to the left atrium.

  1. WARNINGS & PRECAUTIONS

Important: Physicians should inform patients about all potential risks and adverse events discussed in the Directions for Use. This document is not intended to serve as a substitute for the complete labeling.

The Transseptal Cannula is not intended to be extended into the left ventricle.

Product is to be used in a controlled clinical environment by trained medical personnel.

Medical personnel responsible for patient care should minimize the length of time that System components remain inserted or attached to the blood circuit during which there is no blood flow. Examples include start-up and shut-down procedures.

  1. ADVERSE EVENTS

Potential adverse effects that may be associated with transseptal cannulation include the following: injury to or perforation of the myocardial wall with or without cardiac tamponade; thrombus formation; particulate or air embolism; myocardial infarction; cardiac arrhythmias such as atrial fibrillation, heart block, sinus bradycardia, and ventricular tachycardia or fibrillation; congestive heart failure or pulmonary edema; atrial septal defect, transient or persistent, with or without hemodynamic compromise; vascular injury with or without the need for surgical intervention; blood loss requiring fluid replacement or transfusion of blood products; infection; allergy or anaphylactic reaction to contrast media or device components.; loss of limb; respiratory arrest; renal failure; death; failure to traverse the vascular system.


 

Brief Summary of Safety Information for TandemLife® LifeSPARC® System

(Commercial, August 2020)

  1. INDICATIONS FOR USE/INTENDED USE

INDICATION — The LifeSPARC pump is intended to pump blood through an extracorporeal circuit for periods lasting less than 6 hours for the purpose of providing either: (i) Full or partial cardiopulmonary bypass (i.e., circuit includes an oxygenator) during open surgical procedures on the heart or great vessels; or (ii) Temporary circulatory bypass for diversion of flow around a planned disruption of the circulatory pathway necessary for open surgical procedures on the aorta or vena cava.

INTENDED USE — The Pump is intended for use only with the LifeSPARC Controller.

  1. CONTRAINDICATIONS

Because of the non-occlusive nature of the Pump, the Pump should not be used for cardiotomy suction. The LifeSPARC Pump should not be used with extracorporeal circuits which create a pressure differential greater than 600 mmHg between the inflow and outflow of the Pump.

  1. WARNINGS & PRECAUTIONS – GENERAL

Important: Physicians should inform patients about all potential risks and adverse events discussed in the Directions for Use and Operator’s Manuals. This document is not intended to serve as a substitute for the complete labeling.

The LifeSPARC System has not been qualified through in vitro, in vivo, or clinical studies for long term use (i.e., longer than six hours) as a bridge to transplant, for pending recovery of the natural heart, or extracorporeal membrane oxygenation (ECMO).

The LifeSPARC System is for use with Adults Only.

The use of this device for periods longer than six hours may result in pump failure, reduced pumping capability, excessive blood trauma, degradation and/or corrosion of the blood contacting materials (with the possibility of the particles passing through the CPB circuit to the patient), leaks, and increased potential for gaseous emboli entering the arterial line.

Components of the extracorporeal circuit in series with the Pump will influence the attainable flow rates. In general, higher resistance upstream and downstream from the Pump will reduce the flow rate at given RPM settings of the Pump. Consult the pressure- flow curves in this manual.

The Pump should not be stopped for longer than five minutes without consideration of additional anticoagulation as the risk of thromboembolism is increased after blood has remained stagnant in the Pump.

During usage the Pump can get very warm. To prevent burn injury, make sure the Pump is secured in the Pump Holster.

Use in patients with II+ and higher aortic insufficiency may result in diminished net forward flow.

Support with the LifeSPARC system must only be initiated by operators with in- depth training in system use and extensive experience in the management of patients. The operator must have a thorough understanding of cardiac anatomy and physiology, hemodynamic monitoring, fluid and volume balance, and the management of inotropic and vasoactive drugs.

  1. WARNINGS & PRECAUTIONS – ENVIRONMENTAL AND MEDICAL THERAPY HAZARDS INCLUDING MRI

The LifeSPARC System is MR Unsafe.

The LifeSPARC Pump bearing is stabilized by a series of strong magnets that create a strong magnetic field. Do not use LifeSPARC Pump in proximity of other devices that may have function altered in the presence of a magnetic field.

  1. ADVERSE EVENTS

Potential side effects of all extracorporeal circulatory support devices include, but are not limited to, sepsis, hemolysis, and thromboembolism.


 

Brief Summary of Safety Information for TandemLife® TandemLung® System

(Commercial, August 2020)

  1. INDICATIONS FOR USE/INTENDED USE

The TandemLung Oxygenator (TLO) is intended to be used for adult patients for extracorporeal circulation during cardiopulmonary bypass in the field of open-heart surgery. Within the indicated flow rates blood is oxygenated and carbon dioxide is removed. The utilization period of this device is restricted to six hours.

  1. WARNINGS & PRECAUTIONS– GENERAL

Important: Physicians should inform patients about all potential risks and adverse events discussed in the Directions for Use. This document is not intended to serve as a substitute for the complete labeling.

The advantages of extracorporeal circulation need to be weighed against the risks associated with systemic anticoagulation.

The TLO may only be used by persons trained in extracorporeal circulation procedures.

TandemLife recommends the use of an oxygen-air blender (gas blender) for gas control during extracorporeal circulation.

Liquids should never be introduced into the gas pathways.

Excessive gas flow may cause hyperoxia, hypocarbia, alkalosis and/or blood trauma.

  1. WARNINGS & PRECAUTIONS – USE WITH ANESTHETICS AND MEDICATION

If injectable anesthetics such as Propofol are used, they should not be administered immediately upstream of the oxygenator. Furthermore, only small bolus rates or volumes per unit of time should be used because large drug boluses may create fat deposits that impair the function of the oxygenator.

The oxygenator with fiber membrane cannot be used for the administration of volatile anesthetic gases because the gas molecules are unable to pass through the diffusion membrane.

When using the TLO, methylene blue must not be administered directly before or during perfusion.

Arterial connections must not be used to administer medication.

  1. ADVERSE EVENTS

Possible side effects include infections, hemolysis, and embolisms. Side effects associated with extracorporeal circulation in general may also occur (e.g., post- perfusion syndrome and organ damage).
