International Classification:

A61N001/375

US Classification:

607036000, 607037000

Abstract:

A connector block providing electrical coupling to electronic componentry of an implantable medical device. The implantable medical device has a case containing the electronic componentry. A preformed electrically conductive “wireform” mounted with respect to a structurally rigid polymer frame forming a plurality of electrical contacts. Potting is formed in situ with liquid thermoset polymer substantially filling any voids in the connector block and forming a thermoset polymer gasket between the connector block and the case.

Abstract:

A dialysis device for operation in multiple modes and for maintaining a known gradient of potassium ion or other electrolyte between the blood of a patient and a dialysate fluid is described. The dialysis device is capable of being used for hemodialysis or peritoneal dialysis, and the dialysis device is capable of operation with a dialysate purification unit outside of a clinical setting or with a supply of water that can be supplied in a clinical setting. The dialysis device has a composition sensor containing a potassium-sensitive electrode for measuring a potassium ion concentration in one or more of the patient's blood and the dialysate fluid and an infusate pump operated to adjust a potassium ion concentration in the dialysate fluid based at least in part on data from the composition sensor.

A61M 1/28

Abstract:

A blood based solute monitoring system for measuring at least one blood solute species that has a first recirculation flow path in communication with a dialyzer. The first recirculation flow path is configured to allow a fluid to recirculate through a dialyzer such that the concentration of at least one solute species in the fluid becomes equilibrated to the solute species concentration of the blood compartment of the dialyzer. The blood solute monitoring system has at least one sensor to measure a fluid characteristic.

A61M 1/34

Abstract:

The invention relates to devices, systems, and methods for calculating a bicarbonate concentration in a fluid used in dialysis. The devices, systems, and methods can be used to calculate the bicarbonate concentration in either dialysate or blood. The invention measures the amount of carbon dioxide in both an acidified and non-acidified solution and calculates the bicarbonate concentration based on the difference in carbon dioxide concentrations.

Abstract:

A venous air capture chamber for use in dialysis, includes an upwardly extending fluid inlet terminating in first and second fluid inlet ports (). The first and second fluid inlet ports () are opposedly positioned on the fluid inlet at an angle of about 180. The venous air capture chamber also includes a fluid outlet () at the bottom of the chamber body. The venous air capture chamber provides improved fluid dynamics, reducing both stagnant flow and turbulence. The venous air capture chamber also provides for bidirectional flow of fluid through the chamber.
