Feature & Benefits

The BioSentry Tract Sealant System deploys a self-expanding hydrogel plug into the pleural space following a percutaneous lung biopsy. This creates an airtight seal that closes the pleural puncture and provides accuracy in marking a biopsy location for visualization during surgical resection.

  • Hydrogel plug fully resorbs
  • During this time it is visible and marks the biopsy location for surgery
  • The applicator standardizes the method how the plug is placed1
  • Usable with 17 G & 19 G coaxial introducer needles
  • No clinically significant complications associated with use²

MD Anderson Cancer Center denotes a 61% reduction in chest tubes1

Image shows a bar chart with BioSentry in red at 8.2% and Standard of Care in charcoal at 20.8% of patients needing chest tubesHIGHLIGHTS

  • 37% reduction of pneumothorax and 61% reduction of chest tube placement
  • Although the BioSentry System was more frequently used in high-risk patients in the unmatched group, it still demonstrated reduced risk of pneumothorax
  • Use of BioSentry System presents a standardized method for mitigating complications post CT-guided lung biopsy for clinicians

ARR = Absolute Risk Reduction; RRR = Relative Risk Reduction


Retrospective study, comparing patients receiving BioSentry device (318) vs. control arm (1956) during percutaneous lung biopsy. To adjust for potential selection bias, patients in the treated group were matched 1:1 to patients in the control group using propensity score matching.


All-comers study demonstrates 80% reduction in chest tube insertion rates when using the BioSentry System2

Image shows a bar chart with BioSentry in red at 2.0% and Standard of Care in charcoal at 10.0% of patients needing chest tubesHIGHLIGHTS

  • The treatment group demonstrated a significant reduction in chest tube placements
  • With the BioSentry System, patients experienced an 83% reduction in average time of hospital stay post CT-guided percutaneous transthoracic needle biopsy


Retrospective review of 200 consecutive patients (100 consecutive biopsies were done without any intervention and the next 100 consecutive biopsies done with the BioSentry System).
