Set forth are vascular valves and servovalves and methods of using the same that may be positioned in the circulatory system without interrupting blood flow to facilitate solid organ transplantation so as to reduce graft organ anoxia and degradation before and after harvesting and storage, thereby minimizing late-term cardiac allograft vasculopathy as a major cause of graft failure. Along the urinary tract, bypassing bladder-generated urge sensation by diverting urine directly from the ureters to a neobladder or collection bag alleviates intractable incontinence, nocturia, urethral syndrome, overactive bladder, dysuria, or frequency. Where the lower tract is missing, a prosthesis can thwart disease and preclude the degenerative metaplastic transition to carcinoma risked when gut is used to construct a conduit for urine, a neobladder, and / or high-maintenance stoma. Druglines to valves and servovalves can directly pipeline-target medication to nidi, anastomoses, or any other trouble spots.

A cushion promotes healthy blood flow within the body when the patient is sitting / lying down. A pressure controlling support automatically balances user weight, detects application of user weight, or otherwise detects when the user is at-risk for pressure sores. Pressure is dynamically redistributed by inflation / deflation of individual bladders, rebalancing user support. The cushion prevents the user from applying their weight to impede their blood flow at an at-risk location or from cramping their musculature. The cushion also massages the user's musculature, by moving a pressure difference about selected bladders, promoting blood flow and reducing seating fatigue. The cushion detects changes in pressure at each bladder, to detect / predict user fidgeting / movement and adjust pressure in response thereto, to support the user's new position.
