example

[0100] The following prophetic examples serve to provide guidance on how to obtain and interpret data from an implantable sensor configured to measure tissue fluid in a patient in a use or device as described in the detailed description above quantity. It will be appreciated that the foreshadowing example presented here, consistent with the general principles of the case, is only one appropriate means for obtaining and interpreting the monitored data.

[0101] For this prophetic example, an implantable tissue impedance sensor such as the Medtronic A fluid status monitoring system is implanted in a patient to measure tissue impedance between the housing of the device and an electrode extending from the housing via a lead. Well-documented procedures for determining acceptable ranges for tissue impedance and fluid volume have been established. See, eg, (i) Siegenthalar, et al., Journal of Clinical Monitoring and Computing (2010):24:449-451 (Siegenthalar, et al. Journal of Clin...

Abstract

A use includes monitoring an indicator of fluid volume of a patient via a sensor device, and setting an initial fluid volume removal prescription for a blood fluid removal session based on the monitored indicator of fluid volume. The use may further include transmitting data regarding the indicator of fluid volume from the implantable sensor device to fluid removal device. In some embodiments, the fluid removal device sets or calculated the initial fluid volume removal prescription based on the data received from the implantable sensor. The indicator of fluid volume may be an indicator of tissue fluid volume or an indicator of blood fluid volume.
