What Dotter does

Dotter Inc. is a South Korea-based cardiovascular medical device company founded in 2016 that develops and manufactures diagnostic imaging systems and interventional implant devices for ischemic heart disease. The company's product portfolio addresses the full PCI (percutaneous coronary intervention) workflow: the Aurios S100 advanced OCT imaging console and the Benetis fiber-optic OCT catheter provide high-resolution lesion visualization; the Benetis-Lifetime system is the world's first commercialized combined OCT-FLIm (Fluorescence Lifetime Imaging) platform that simultaneously captures morphological and biochemical images of the vessel wall without external contrast agents; the Venavis NC/SC balloon catheter supports angioplasty procedures; the EluNIR drug-eluting stent is exclusively licensed from Israel's Medinol for Korean distribution; and the proprietary BRS (bioresorbable stent) features a patented V-shaped design with 100μm strut thickness, 30% thinner than competitors, and fully resorbs within approximately three years. AI-based software integrated into Aurios provides automated image analysis, stenosis quantification, 3D reconstruction, and predictive risk stratification via neural network learning. The company operates GMP-certified manufacturing facilities in Seoul and Incheon, an R&D laboratory in Ulsan, and its corporate headquarters in Incheon.

Dotter's business model centers on direct sales of medical hardware and recurring single-use catheters/consumables to Korean university hospitals and interventional cardiology centers. The flagship BRS is undergoing MFDS confirmatory clinical trials (128-patient enrollment completed in March 2024 at 10 Korean university hospitals including Samsung Seoul Hospital and Sinchon Severance Hospital), while OCT imaging systems and Benetis catheters are already MFDS-approved and commercially available. Distribution is geographically limited to a single market (South Korea), with named institutional customers including Samsung Seoul Hospital, Sinchon Severance Hospital, and Ulsan Hospital. Pricing is not publicly disclosed and is presumed to follow hospital procurement negotiation processes. The company has raised approximately 190억 KRW (~$14M USD) cumulatively across seed (2020), Series A (2021), and Series B (March 2024) rounds, and was selected by Korea's 중기부 as one of 50 startups with unicorn potential by 2030.

Compatible with standard 0.014" guidewires and OCT imaging consoles, with radiopaque markers at the distal tip and proximal to the lens for aligning OCT pullback in the region of interest. Sold as a single-use consumable paired with the Aurios OCT system.
• Venavis Balloon Catheter (NC & SC) Double-lumen percutaneous transluminal coronary angioplasty (PTCA) balloon catheter with balloon at the distal end, available in NC (Non-Compliant) and SC (Semi-Compliant) variants. Features improved trackability, pushability, and crossability with platinum-iridium markers, and is compatible with 5F and 6F guide catheters. Used in pre-dilation and stent deployment during PCI.
• BRS Bioresorbable Stent Third-generation bioresorbable coronary scaffold with 100μm strut thickness (the thinnest among competitors, approximately 30% thinner than competing devices). Uses proprietary V-shaped stent design for high radial force and MPC (phosphorylcholine) polymer coating for biocompatibility and stable drug release. Fully resorbed by the body in approximately 3 years, enabling re-operation in the same vessel and reducing antiplatelet drug dependency to roughly one year compared with permanent metal drug-eluting stents.
• EluNIR Drug-Eluting Stent Ridaforolimus-eluting drug-eluting stent system featuring Medinol's proprietary WiZeCell variable-width W-Z strut design, with ultra-narrow 40μm Z-struts for flexibility and conformability and narrow W-struts for radial strength, plus elastomeric coating technology. Developed by Medinol (Israel) and exclusively distributed in Korea by Dotter under an agreement signed in November 2022, with Korean market launch in early 2023.
• Benetis-Lifetime OCT-FLIm Imaging System Combined OCT and FLIm (Fluorescence Lifetime Imaging) cardiovascular diagnostic system. Uses an optical fiber catheter inserted into blood vessels to simultaneously capture morphological and biochemical images of the inner vessel wall in real-time without external contrast medium. Achieves 200kHz resolution, more than double the 90kHz of competitors. World's first to commercialize this technology, enabling detection of high-risk atherosclerotic plaques that standard OCT or IVUS cannot identify.
