A sphincter augmentation device includes a plurality of bodies and a linking structure linking the plurality of bodies together to form an annular array. Each body includes a housing and magnets positioned within the housing. The magnets magnetically bias the bodies toward one another and are movable within the housing. The annular array is sized to be positioned around a human lower esophageal sphincter so that the bodies and the linking structure bear inwardly against the lower esophageal sphincter. The annular array is configured to transition between a radially expanded state and a radially contracted state to constrict the lower esophageal sphincter. The magnets are configured to move relative to the housing of each body between a first position and a second position. In the first position the magnets are magnetically aligned with each other. In the second position the magnets are aligned with an externally applied magnetic field.

The first segment being coupled to the handle. The second segment being pivotally connected to the first segment. The articulation driving mechanism being configured to pivot the second segment about the first segment upon articulation.

A magnetic control device (30) for a capsule endoscope (10) including at least a first magnet (11) and an imaging device (12), and the capsule endoscope (10) is located in a tissue cavity (3). The magnetic control device (30) includes a second magnet (31) and a first induction coil (32) arranged around the second magnet (31). The magnetic control device (30) is configured to generate a driving force to the capsule endoscope (10) to move the capsule endoscope (10) from a first position (P1) in the tissue cavity (3) to a second position towards an opposite side in the tissue cavity (3); to control a variable magnetic field to decelerate the capsule endoscope (10) to a predetermined speed when the capsule endoscope (10) approaches the second position (P2); and to generate the variable magnetic field for the capsule endoscope (10).

Techniques for operating and monitoring an endoscopic balloon dilation system. The endoscopic balloon dilation system includes: an endoscope configured to be inserted into an esophagus of a patient; a balloon catheter comprising a balloon, the balloon catheter configured to pass through the endoscope into the esophagus of the patient; a balloon inflation device fluidly coupled to the balloon catheter, the balloon inflation device configured to dilate the balloon by flowing fluid into the balloon; a digital dilation monitor fluidly coupled to the balloon catheter and the balloon inflation device, the digital dilation monitor configured to measure at least one property of the balloon; a processor; and a non-transitory computer-readable storage medium storing processor executable instructions that, when executed by the processor, cause the processor to: receive, from the digital dilation monitor, information representing the at least one property of the balloon; and display, on a display device, a visual representation of the at least one property of the balloon.

An implantable tissue connector (1; 1a) adapted to be connected to a tubular part of living tissue (70; 80) within a patient's body (100) comprises a conduit (2) and at least one flexible sleeve (10) adapted to axially extend and closely fit around at least part of the outer surface (6) of the conduit. The conduit is inserted into the tubular part of living tissue and the flexible sleeve placed over the tubular part of living tissue. Various alternatives are described of how the living tissue may be prevented form slipping off of the conduit.

A light source device includes a first light source, a second light source, and a processor. The processor controls, based on spectrum setting information, an emitted light amount of the first light source and an emitted light amount of the second light source so that the emitted light amount of the first light source becomes larger than the emitted light amount of the second light source. The observation object includes a region of interest, a merkmal, and a peripheral portion. The spectrum setting information is set based on a merkmal observed ratio that is a ratio between a spectral reflectance in the merkmal and a spectral reflectance in the peripheral portion. A degree of disassociation of the merkmal observed ratio in the first wavelength region from 1 is greater than a degree of disassociation of the merkmal observed ratio in the second wavelength region from 1.
