Abstract:
A dialysis fluid cassette includes a rigid portion defining at least one valve chamber, the rigid portion further defining an air separation chamber, the air separation chamber when in an operating position including a first sidewall and a second sidewall, a first fluid opening, a second fluid opening, and a separation wall extending from the first sidewall to the second sidewall, the separation wall having a free edge residing within the air separation chamber, the separation wall forcing the dialysis fluid to flow from one of the fluid openings around the free edge of the separation wall to the other of the openings.

Abstract:
An applicator device (10) for applying at least one agent to a target site, including: a rigid section (18) configured for the passage of fluid therethrough, the rigid section having a proximal end portion (26) and a distal end portion (22), the proximal end portion configured for communication with at least one fluid reservoir (80, 90; see fig 4A); a formable section (24, see fig. 2) attached to the distal end portion of the rigid section, the formable section configured to be shaped into a desired configuration, the formable section including at least a first lumen (124, 126; see fig. 5) and a second lumen (120), the first lumen configured to receive fluid from the rigid section; and a malleable member (122) positioned within the second lumen (120), wherein the malleable member is configured to assist in retaining the formable section in the desired configuration.
Abstract:
A dialysis fluid cassette (10) includes a rigid portion defining first and second valve chambers (22, 24), the rigid portion further defining an air separation chamber (52) in fluid communication with the first and second valve chambers, the air separation chamber including a baffle (80a) and structured such that when the cassette is placed in a dialysis instrument, (i) the baffle extends upwardly from a bottom of the air separation chamber and (ii) first and second openings to the air separation chamber, communicating fluidly and respectively with the first and second valve chambers, are located near the bottom of the air separation chamber, such that the dialysis fluid is forced up one side of the baffle and down the other side of the baffle when flowing through the air separation chamber.
Abstract:
A dialysis fluid heating system includes a plurality of conductive tubes; first and second end caps located at first and second ends of the tubes, respectively, the first end cap including a dialysis fluid inlet and a dialysis fluid outlet, the end caps and the tubes configured such that dialysis fluid can flow from the fluid inlet of the first end cap, through at least one first tube to the second end cap, and through at least one second tube back to the first end cap; a conductive wire wound around an outside of the conductive tubes; and electronics configured to supply power to the conductive wire, the wire forming a primary coil of a transformer, the tubes forming a secondary coil of the transformer.
