Description of intervention(s) / exposure
Treatment: Devices - PCL Pectus Scaffold implantation and autologous fat grafting

Experimental: Insertion of PCL Pectus scaffold - Insertion of a custom-made 3D printed medical-grade polycaprolactone (PCL) Pectus scaffold with autologous fat graft for pectus excavatum defect correction.


Treatment: Devices: PCL Pectus Scaffold implantation and autologous fat grafting
A small incision is made in the chest and pre-sternal pocked is defined. Following this, an empty scaffold is implanted at the site of the defect with skin closed directly over it. At the same stage, autologous fat transfer will be performed, harvesting fat from available donor sites such as the thighs and abdomen - depending on scaffold volume and patient morphology. The area will be infiltrated with local anaesthetic tumescent fluid, liposuction performed, and fat transferred to syringes for filtration prior to injection into the scaffold. Fat will not be processed beyond simple filtration to separate liquid from fat to be injected. The scaffold provides structural stability to the chest during the infiltration of the tissue inside the scaffold.

Eligibility
Key inclusion criteria
1. Pectus excavatum defect
2. Patient aged =18 and <55 years (patients 55 years and over may still be eligible pending assessment by investigating team and documentation of rationale)
3. Patient willing and able to comply with the study requirements.
4. Patient is eligible to undergo MRI (i.e., no implanted incompatible metal or metal devices, no history of severe claustrophobia).
5. Patient capable of providing valid informed consent.
Minimum age
18 Years
Maximum age
54 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Patient with a known history of immunodeficiency including HIV, concomitant systemic corticosteroid therapy, chemotherapy, synchronous haematological malignancy or other cause for secondary/primary immunodeficiency.
2. Patient with known severe concurrent or inter-current illness including cardiovascular, respiratory or immunological illness, psychiatric disorders, alcohol or chemical dependence, possible allergies that would, in the opinion of the Principal Investigator, compromise their safety or compliance or interfere with interpretation of study results.
3. Patient with unstable cardiac or respiratory function due to pectus excavatum or those requiring functional repair.
4. Patients with Body Mass Index (BMI) below 18.5 kg/m2 and above 30 kg/m2. NB: Patients with BMI up to 10% higher than the upper limit (up to 33 kg/m2) can be still enrolled if the treating surgeon confirms that BMI is not associated with any kind of pathology.
5. Patient with polycaprolactone (PCL) allergy
6. Women who are currently pregnant or breast feeding, or who are planning to become pregnant within two years after the pectus excavatum camouflage surgery.
7. Women of childbearing potential without an appropriate contraceptive method.
8. Patient with life expectancy < 36 months.
