Seven New Data Sets Demonstrate Penumbra’s Computer Assisted Vacuum Thrombectomy (CAVT) Technology Is Safe, Fast and Effective, Improves Patient Outcomes, and Delivers Healthcare Resource Benefits
Penumbra, Inc., News
ALAMEDA, Calif. – Penumbra, Inc, announced seven significant computer assisted vacuum thrombectomy (CAVT™) data presentations during the 2025 Society of Interventional Radiology (SIR) Annual Scientific Meeting. The data showed that CAVT as a frontline therapy for blood clots not only improved clinical and functional outcomes but can also help reduce overall healthcare costs.
“With this growing body of evidence across several disease states, we are continuously demonstrating the wide-ranging impact CAVT can have as a frontline option on patient outcomes, quality of life and resource utilization in the healthcare system,” said James F. Benenati, M.D., FSIR, chief medical officer at Penumbra. “This extensive research and innovation in clot management underscores our commitment to save lives, improve patient outcomes and positively impact healthcare economics.”
STRIKE-PE Continued to Showcase CAVT’s Speed, Safety and Simplicity in the Treatment of PE
All four presentations featuring interim results of STRIKE-PE demonstrated CAVT is a safe, fast and effective procedure for the treatment of pulmonary embolism (PE). Most notably, the subgroup analysis that evaluated the use of Lightning Flash™ only to treat PE showed:
• Significant reduction of right ventricle/left ventricle ratio by 27.8% and a decrease in mean pulmonary artery pressures by 24.5%
• Low overall major adverse event rate of under 1%
• Fast device time of 25.5 minutes (median)
Enrolling up to 1,500 patients, STRIKE-PE is one of the largest and most comprehensive PE trials with long-term functional and quality of life data. It was recognized at SIR for winning the JVIR Outstanding Clinical Study Award for the 2024 publication.
STRIDE Subset Analysis Showed High Limb Salvage Rate in LE-ALI with CAVT Use
A subset analysis of the STRIDE study demonstrated that when CAVT was used to address lower-extremity acute limb ischemia (LE-ALI) in both in-stent thrombosis and native-vessel thrombosis patients, the procedure was safe and effective with high target limb salvage rates at 30 days.
CAVT Decreased Healthcare Resource Utilization for LE-ALI and Lower Extremity Venous Thrombus
The results of the THRIVE study, a retrospective analysis of resource use and clinical outcomes with LE-ALI that compared CAVT use vs. embolectomy alone and vs. embolectomy with bypass, showed that CAVT was associated with:
· 99.1% limb salvage rate
· 26-46% shorter total hospital length of stay
· 46-75% higher rate of patients discharged home
Additionally, in a retrospective analysis evaluating CAVT use compared to anticoagulation alone to manage lower extremity venous thrombus, the results showed that CAVT was associated with:
· 17% shorter total hospital length of stay
· 40% higher rate of patients discharged home
These retrospective studies utilized the Vizient Clinical Data Base to identify patients with LE-ALI and lower extremity venous thrombus, respectively.
Separate from the SIR Annual Scientific Meeting, health economic data will be presented at other upcoming conferences showing hospital executives and leaders the significant positive economic benefits to the healthcare system of using CAVT in arterial and venous cases.
