Pneumothorax

US-based medical device company Surgical Specialties has secured approval for its upgraded BioSentry Track Sealant System to launch in Europe.

The technology can now be used with a larger 17 gauge biopsy system for percutaneous transthoracic lung biopsy to reduce the risk of pneumothorax and other problems.

Lung biopsies are instrumental in determining patient-specific treatments and there has been an increased demand for larger tissue samples following the availability of more tumour specific therapies. Larger needles increase the risk of pneumothorax.

Frankfurt University, Germany professor Tomas Vogl said: "This change is of significant benefit for European radiologists because the addition of 17 gauge biopsy system compatibility allows larger tissue samples that give us better diagnosis and treatment options.

"Previously we have not had any preventative measures to reduce pneumothorax and related adverse events after a lung biopsy until now with BioSentry."

Pneumothorax is characterised by a collapsed lung caused when air leaks into the space between lung and chest wall.

This may be triggered by a blunt or penetrating chest injury, certain medical procedures, or damage from underlying lung disease.

"Previously we have not had any preventative measures to reduce pneumothorax and related adverse events after a lung biopsy until now with BioSentry."

The CE mark approved BioSentry System implants a self-expanding hydrogel plug into the pleural space following biopsy which expands to prevent air from leaking out causing pneumothorax.

The hydrogel plug is composed of a synthetic tissue-friendly polymer that fully reabsorbs into the body and its co-axial adapter adapts with the coaxial needle for the proper delivery and placement of the plug.

It’s delivery system features depth markings which allows accurate and consistent placement based on CT-guided measurements while the depth adjustment wheel and locking mechanism ensures a proper plug placement.

BioSentry offers new therapy option exhibiting positive clinical outcomes with the 19 gauge biopsy system, and now with a 17 gauge biopsy system.
