EnsiteVascular, LLC

EnsiteVascular is a specialized medical device manufacturer focused exclusively on vascular closure solutions for catheter-based cardiovascular procedures. The company develops and markets the SITESEAL® and SITESEAL SV™ device families—FDA-cleared, non-implant vascular closure devices designed for electrophysiology (EP), interventional cardiology, and structural heart procedures. SITESEAL® is engineered for arterial and venous access closure across all sheath sizes, including large-bore interventions (EVAR, TEVAR, TAVI), offering hemostasis without leaving foreign material behind. Key differentiators include no sheath size limitations, closure of multiple sheaths in a single vessel, rapid hemostasis (typically under 5 minutes), immediate patient mobility, and reduced access-site complications. Clinical data demonstrates zero hematomas or delayed bleeding in a 138-patient comparative study versus suture-based and collagen-plug competitors. The device improves cath lab workflow efficiency, reduces procedure-related costs per access site, and enhances patient comfort and ambulation recovery. SITESEAL® targets high-volume hospital catheterization labs, ambulatory surgery centers, and EP procedure centers across the United States, competing in the $1.4 billion annual vascular closure market.
