Semprus BioSciences develops advanced surface modification technology for medical devices. Its core product is a proprietary polymer-based coating creating a permanently antimicrobial and lubricious surface on implantable devices. This innovation reduces biological fouling and thrombus formation, mitigating complications from long-term use. The approach establishes a stable, biocompatible interface.
Christopher Loose, an MIT PhD, and David Lucchino, an MIT MBA, co-founded Semprus BioSciences in 2007. They addressed critical medical device safety challenges. Loose contributed expertise; Lucchino, business acumen. The insight: an urgent need for a universal solution against device infections and inflammation, compromising patient outcomes.
Semprus BioSciences' technology serves medical device manufacturers improving product biocompatibility and durability. This impacts devices like cardiovascular catheters and orthopedic implants, where biological interactions pose risks. The company’s vision aimed to redefine medical device surface standards, ensuring optimal function, enhancing patient well-being.

Semprus BioSciences was a biotechnology company that developed an implantable, permanent antimicrobial coating technology for medical devices, enabling coatings on devices of various sizes, shapes, and materials to prevent bacterial infections.[1][2] It targeted the medical device market, serving healthcare providers and patients by solving the critical problem of device-related infections, particularly for implants like venous catheters; its flagship Semprus Sustain technology received FDA clearance and EU designation for safety and efficacy.[2] Founded in 2006 in Cambridge, Massachusetts, the company raised $28.5M, achieved rapid growth through seed funding including MIT's $100K Entrepreneurship Competition, and was acquired by Teleflex in 2012 for up to $80M, after which it operated as a subsidiary advancing the technology.[1][2]
Semprus BioSciences emerged from research at MIT by Matthew Loose, who developed a novel biomaterial that creates a permanent bacteria barrier for implanted devices, as detailed in a 2012 journal paper.[2] The startup, founded in 2006 in Kendall Square, Cambridge, Massachusetts, was seed-funded in part by the MIT $100K Entrepreneurship Competition and attracted millions in private and federal funding over six years.[2] Early success came from a "listening tour" to validate the infection problem in medical devices, leading to targeted development; this human-centered approach, emphasized by co-founder Greg Lucchino, drove pivotal traction including FDA clearance for its first product in venous catheters.[2]
Semprus rode the wave of biomaterials innovation in medtech, addressing hospital-acquired infections—a major market force, as device-related bacteria affect millions annually and drive up healthcare costs.[2] Its timing aligned with rising demand for infection-resistant implants amid antibiotic resistance trends and stricter regulatory pushes for safer devices in the early 2010s.[1][2] By pioneering scalable, permanent coatings, Semprus influenced the ecosystem, validating MIT spinouts in Kendall Square biotech hubs and paving the way for Teleflex's expanded portfolio, which amplified the technology's reach in global medtech.[2]
Post-2012 acquisition, Semprus operates as a Teleflex subsidiary, likely iterating on coatings for broader device applications amid ongoing antimicrobial resistance challenges.[1][2] Trends like AI-driven material design and personalized implants will shape its path, potentially expanding to new markets like orthopedics or wearables. Its legacy underscores how targeted biotech solves entrenched clinical pain points, positioning Teleflex—and by extension, Semprus tech—for sustained impact in safer medical interventions, echoing its origins as a fast-scaling infection fighter.
Semprus BioSciences has raised $18.0M across 1 funding round. Most recently, it raised $18.0M Series B in December 2010.
