Patent number: 11484190Abstract: A medical capsule is equipped with a sensor device having light emitting and light receiving elements. The sensor device can detect blood on the basis of light absorption properties of the blood. The capsule has a casing forming a recess or gap at its outer surface. The recess has a pre-selected width which represents a fixed measuring track between the light emitting and light receiving elements being arranged at opposing sides of the recess or gap when seen in its width direction. The medical capsule also has a shielding plate/layer/membrane arranged at least at or near the bottom of the recess or gap and extending along the width direction of the recess or gap preferably to exceed the recess at both sides into its width direction to prohibit emitted light from bypassing the recess via the casing material of the capsule.Type: GrantFiled: May 29, 2017Date of Patent: November 1, 2022Inventors: Marc O.

Patent number: 10820788Abstract: A capsule endomicroscope has a predetermined axial length and a diameter smaller than the axial length. The endomicroscope can acquire images of a surface of a hollow organ, and includes a microscopic image acquisition assembly having an optical axis oriented in a radial direction of the endomicroscope to acquire microscopic images of a section of the surface of a hollow organ present in a predetermined image acquisition area on a radial outer surface of the endomicroscope through a housing of the endomicroscope that has sectionally light-transparent material. A light source emits light rays in a radial direction through the light-transparent material of the housing during image acquisition. The light source and the light-transparent material of the housing located between the light source and the predetermined image acquisition area are interconnected to each other such that no refraction interface exists between the light source and the image acquisition area.Type: GrantFiled: November 3, 2017Date of Patent: November 3, 2020Assignee: OVESCO ENDOSCOPY AGInventors: Sebastian Schostek, Alyssa Albiez, Marc O.
