Abstract:
1. A blood gas exchanger system comprising: a plurality of compliant blood gas exchangers, arranged anatomically as an artificial respiratory prosthesis, for enabling oxygen and carbon dioxide exchange in circulating venous blood, a compliant blood gas exchanger of the plurality of exchangers comprising: a housing having a first end, a second end opposing the first end, and an elastomeric sidewall extending there between, the elastomeric sidewall bounding a chamber, the chamber being in communication with a blood inlet subconduit and a blood outlet subconduit; a first support member disposed at least partially within the housing at the first end of the housing, the first support member being in communication with a gas inlet subconduit; a second support member disposed at least partially within the housing at the second end of the housing, the second support member being in communication with a gas outlet subconduit; the blood outlet subconduit having a sealed end and an open end, the open end of the blood outlet subconduit extending beyond the second support member; a plurality of hollow fibers having a first fiber end secured by the first support member and a second fiber end secured by the second support member, the plurality of hollow fibers having a porous surface through which the plurality of hollow fibers is capable of gaseous exchange but not liquid exchange and surrounding the blood outlet subconduit at said second fiber end; a blood inlet conduit in fluid communication with the blood inlet subconduit; a blood outlet conduit in fluid communication with the blood outlet subconduit; a gas inlet conduit in fluid communication with the gas inlet subconduit; and a gas outlet conduit in fluid communication with the gas outlet subconduit.
