Segmentation by type classifies implantable continuous glucose monitors into subcutaneous implants, intravascular implants, and hybrid systems. Subcutaneous implants, which reside in the interstitial tissue, dominate the technology mix, representing about 65 % of unit shipments due to their established safety profile and minimally invasive insertion procedures. Intravascular implants, positioned directly within the bloodstream, capture a smaller but rapidly growing share—estimated at 25 %—as advances in biocompatible sensor coatings improve longevity and reduce thrombosis risk. Hybrid systems, combining subcutaneous sensor elements with transdermal data transmission modules, occupy the remaining 10 % of the market, appealing to patients seeking extended sensor life without repeated procedures. The relative contribution of each type to market size reflects manufacturing complexity, device lifespan, and reimbursement coding, with subcutaneous devices generating the bulk of revenue while intravascular and hybrid solutions command higher per‑unit pricing due to their specialized clinical benefits.
