Lung Cannula Set™
Single-use, sterile disposable product
Lung Cannula Set™ is a sterile, single-use set to be used to connect isolated donor lungs to an extracorporeal perfusion system for ex-vivo assessment. The cannulas are made of PVC and medical-grade TPE, both of which are FDA Class VI biocompatible, DEHP and latex-free.
Easy to connect and check
Built-in pressure lines facilitate reliable readings to avoid any hydrostatic damage to the lungs. The luer lock connections enable easy connection to monitoring equipment.
Optimal material and design
PVC and medical-grade TPE material selected for easy handling. The material gives stability yet is soft enough for running sutures.
The Lung Cannula Set™ is designed to work with the Organ Chamber™. Cannula positions should be checked and especially a gentle traction on the LA cannula is applied to assure good patency of pulmonary veins.
Features
- Built-in pressure lines
- Easy to connect – with luer lock connections
- Color coded to indicate PA (yellow) and LA (green) usage
- PVC and medical-grade TPE material selected for easy handling
- Material selected for optimal stability yet soft enough for running sutures
- Extra cannula for backup or if unsufficient tissue available
- Designed to fit with Organ Chamber™
Color-coding facilitates
The cannula set contains three color-coded cannulas in sterile packaging. Straight cannula with yellow cap to be used for the pulmonary artery (PA), cone cannula with green cap to be used for the left atrial (LA) cuff and a cone cannula with white luer-capped end to be used as a back-up cannula either to the pulmonary artery or left atrial.
Straight cannula with yellow cap to be used for the pulmonary artery.
Cone cannula with green luer-capped end to be used for the left atrial cuff.
Cone cannula with white luer-capped end to be used as a back-up cannula either to the pulmonary artery or left atrial cuff.
In clinical usage
Several descriptions of clinical usage of the cannula are available in the literature1,2,3. The directions for use is only provided as a suggested procedure. The user must on the basis of her or his medical training and experience evaluate the suitability of this procedure.
The LA appendage is trimmed off and the specially designed funnel-shaped cannula with built-in pressure line is sewn to the LA cuff with a 4-0 monofilament suture to create a closed circuit. The cannula splints the LA open to create a reliable and consistent outflow drainage. Connect the pressure line to sensor via green-capped luer end.
The straight cannula is placed into the pulmonary artery up to the point of bifurcation and tied into place with umbilical tape tied across the pulmonary artery around the cannula´s grooved radius. When enough cuff for PA is available the cannula is secured with 0 silk ties, or if the cuff is too short the same funnel-shaped cannula used for LA (green capped) cannulation can be used.
The PVC and medical-grade TPE material was selected to facilitate trimming of funnel to fit either left atrial cuff radius or the pulmonary artery.
If cuffs are too short, additional donor tissue such as aorta, pericardium, or vena cava can be used to construct neo-cuffs4.

*Humanitarian Device. Authorized by Federal law in the USA for use in flushing and temporary continuous normothermic machine perfusion of initially unacceptable excised donor lungs during which time the ex-vivo function of the lungs can be reassessed for transplantation. The effectiveness of this device for this use has not been demonstrated.
