Stent delivery system, endoscope system, and stent indwelling method

USPTO issued Patent US12589015B2 to Olympus Corporation on March 31, 2026, granting exclusive rights to the disclosed stent delivery system, endoscope system, and associated stent indwelling method. The patent describes a configuration where an inner tube is inserted through a first opening in the distal end of an outer tube and exits through a second opening to be disposed outside the outer tube, with the stent stored between the tubes. The system is designed for insertion into an endoscope channel. This grant represents the completion of the patent examination process for application 17888695.

This is a routine patent grant notice with no compliance obligations or deadlines. Medical device manufacturers, particularly those developing stent delivery systems or endoscopic tools, should review the patent claims to assess potential freedom-to-operate considerations or licensing needs. The patent grant does not impose regulatory requirements but establishes intellectual property rights that may affect competitive product development strategies.
