Maple Grove Is the Structural Heart Corridor of America's Medical Alley
Maple Grove is not a city with a cardiac device cluster — Maple Grove is structural heart manufacturing. Boston Scientific chose Maple Grove for its structural heart and coronary intervention manufacturing operations, anchoring the WATCHMAN FLX left atrial appendage (LAA) closure program and coronary stent tooling — the PROMUS Premier, Synergy, and REBEL platforms that treat millions of AFib and CAD patients worldwide. The WATCHMAN FLX received FDA approval in 2020 for LAA closure in nonvalvular atrial fibrillation patients, and the 100K+ patient milestone demonstrates the manufacturing scale Boston Scientific has built in this ZIP code. Pairing with Plymouth's Medtronic CRM corridor six miles to the southeast, Maple Grove and Plymouth together form the world's densest cardiovascular implant engineering corridor. Around the Boston Scientific anchor sit Cardiovascular Systems Inc. (CSI) with its orbital atherectomy systems, SurModics with its surface modification and drug-delivery coating technology, and Upsher-Smith Laboratories at 6701 Evenstad Dr on the Plymouth/Maple Grove border. RivCut machines the tooling, fixturing, and precision hardware that make these cardiovascular programs possible — not the implants themselves, but the mandrels, dies, fixtures, and gauges the engineers need to build and inspect them.

Built for the Structural Heart Cardiovascular Device Corridor
Maple Grove (45.0869°N, 93.4557°W; pop. ~74K; Hennepin County suburb ~15 miles northwest of Minneapolis) is the structural heart manufacturing capital of Minnesota's Medical Alley. Boston Scientific chose Maple Grove for its structural heart and coronary intervention manufacturing operations — anchoring the WATCHMAN FLX left atrial appendage closure program and coronary stent tooling for the PROMUS Premier, Synergy, and REBEL platforms. WATCHMAN FLX received FDA approval in 2020 for LAA closure in nonvalvular atrial fibrillation patients; the 100K+ patient milestone reflects the manufacturing scale Boston Scientific has built inside this ZIP code. Pairing with Plymouth's Medtronic CRM corridor six miles to the southeast, Maple Grove and Plymouth together form the world's densest cardiovascular implant engineering corridor — a density the Medical Alley Association's 800+ member network makes visible.
The engineering demand here is tooling and fixturing, not implants. Boston Scientific engineers need nitinol frame expansion mandrels, heat-setting fixture sets, stent laser-cutting dies, Co-Cr crimping mandrels, inspection gauges, and precision delivery system hardware. Cardiovascular Systems Inc. (CSI) requires orbital atherectomy tooling and fixturing. SurModics needs coating-process substrate fixtures. Upsher-Smith Laboratories at 6701 Evenstad Dr needs validated-clean pharma tooling. RivCut is a qualified second-source for all of it — instant online quoting, free DFM, ISO 13485-aligned documentation, Zeiss CMM inspection on every part, ASTM A967 passivation, cleanroom packaging, and no minimum order quantity. All parts are CNC machined in-house at our Bay Area facility. We never broker. We never outsource. Learn about RivCut →
