title = "Hydrogel check valve with non-zero cracking pressure for use as a potential alternative hydrocephalus treatment method",
abstract = "An alternative method of treating hydrocephalus by means of cranially confining and miniaturizing draining mechanisms may offer greater safety and reliability than standard cerebrospinal fluid (CSF) shunts that suffer from high failure rates partly related to their physically large form (2 long catheters and 1 valve) and implant coverage (brain to distal organs). This passive check valve targets restoration of near natural CSF draining operations and attempts to mitigate common valve complications such as back flow and steady state leakage. A simple perforated hydrogel membrane forms the basic check valve structure and its swelling characteristics provide the sealing to diminish leakage. Preliminary measurements demonstrate its ability to operate within an appropriate range of-800<δP<600 mmH2O, establish a targeted PT≈20-110 mmH 2O, and substantially lower reverse flow leakage for δP<PT.",
