Abstract: A flexible intestinal anastomosis stent which sucks secretions on an inner wall of an intestinal tract and at a suture site into a horn-shaped channel through a through-hole. The secretion is discharged to an inside of the stent body through a liquid-inlet hole after being squeezed by intestinal tract contents, thereby reducing a risk of infection at the suture site. A lower edge of the outlet end of the stent body has a concave polygonal structure, each reflex angle at a lower edge of the concave polygonal structure being formed with one inwardly folded wrinkle structure on a side wall of the stent body, and the wrinkle structure also able to accommodate the secretions. The lower edge is stressed and deformed by the intestinal tract contents to reduce a reflex angle, so that secretions in the wrinkle structure are discharged downwardly, such that risk of complications is reduced.

Abstract: An implantable medical device that has a source of renewable power and has a mechanical structure to expand or collapse at a selected rate and volume to modify intracranial pressure and cerebral fluid circulation. The implantable medical device may be programmed to increase intracranial pressure variably to a prescribed amount in the range of several pascals cyclically and at a prescribed frequency, notably at 0.05 Hz, to produces cyclic intracranial pressure variations. Typically those amplitudes and frequencies drive the glymphatic flow in the brain during deep sleep. This allows the implantable medical device to provide pressure oscillations at prescribed time, for example during NREM sleep, that boost glymphatic CSF circulation in the brain, and which remove toxic and metabolic waste from the brain. The glymphatic circulation may protect patients from neurodegenerative diseases, most notably Alzheimer's Disease.
