Abstract: A system and method of non-invasive or minimally invasive evaluating the cardiovascular system parameters to estimate the cardiac output and circulating blood volume of a patient undergoing hemodialysis. Intravascular indicators are stimulated, and emissions patterns detected for computation of cardiac output, cardiac index, blood volume and other indicators of cardiovascular health before and during hemodialysis.

Abstract: The invention relates to devices and methods for positioning an implant at a target location in the body. The methods include testing an implant while within an injection device at a target location to determine whether the implant is functioning effectively. The methods also include testing from or delivery of materials to the target location during implantation, and loading the injection device for use. The device may be configured to permit the longitudinal and/or axial position of the implant to be maintained relative to an injection device during implantation. The device may also be configured to permit testing of the implant. The invention also may include implants configured for use in the injection devices.
