What changed
Olympus Corporation has filed a patent application for an ultrasound endoscope access device designed to pierce hollow organs during medical procedures. The device comprises an access pipe configured for insertion into an endoscope sheath, a piercer at the distal end for puncturing through the digestive tract into hollow organs, and a treatment tool channel. The key innovation is a dual-configuration system where the first configuration activates the piercing function to enter the hollow organ interior, and the second configuration deactivates piercing while maintaining connection to the organ interior.
This patent application does not create immediate compliance obligations for medical device manufacturers or healthcare providers. Entities developing endoscopic access devices or related surgical instruments should review the claims to assess potential patent landscape implications for their own products. The published application establishes priority dates of December 9, 2025, which may affect the patentability of similar inventions.

Abstract
An access device used with an endoscope includes an access pipe configured to be inserted into a sheath of the endoscope, a piercer disposed on a distal end portion of the access pipe and configured to pierce into a hollow organ through a digestive tract of a patient, and a treatment tool configured to be inserted into the access pipe and to be introduced into the hollow organ by the piercer. The access device is switchable between a first configuration and a second configuration. In the first configuration, a piercing function of the piercer is switched on, so that the piercer pierces the digestive tract and the hollow organ to enter into an interior of the hollow organ, and in the second configuration, the piercing function of the piercer is switched off, the piercer is kept connected to the interior of the hollow organ.
