摘要:
Method and apparatus to automatically monitor and control a perfusion hyperthermia treatment using a system including one or more programmed computers, and mechanical and sensor subsystems. The system includes a fluid path between a patient and an external fluid-treatment subsystem, wherein control of the external fluid-treatment subsystem includes feedback from sensors coupled to the patient. The resulting integrated system provides automated monitoring and control of the patient, the external fluid-treatment subsystem, and the treatment. In one embodiment, the fluid passing between the patient and the external fluid-treatment subsystem is blood. In one embodiment, an apparatus and method are provided for using a computerized system for a perfusion hyper/hypothermia treatment of a patient which obtains a body fluid having a temperature. A plurality of temperature signals representative of temperatures at each of a plurality of patient locations on or within the patient are coupled to the computer system. Measured temperatures are compared to a set of stored parameters in the computer system to generate a comparison value which controls a change in the temperature of the body fluid. The body fluid is then perfused into the patient to either warm, cool, or maintain the current temperature of the patient. In one such embodiment, the body fluid is blood withdrawn from the patient. In another such embodiment, the body fluid is saline.

An implantable medical system includes a first die substrate with a first outer surface. The system also includes a second die substrate with a second outer surface. Furthermore, the system includes a medical device with a first portion that is mounted to the first die substrate and a second portion that is mounted to the second die substrate. The first and second die substrates are fixed to each other and substantially hermetically sealed to each other. Also, the medical device is substantially encapsulated between the first and second die substrates. The first portion is electrically connected to the second portion. Moreover, the first and second outer surfaces of the first and second die substrates are directly exposed to a biological material.

An implantable pressure sensor, which may be incorporated within an implantable medical electrical lead, includes an insulative sidewall, which contains a gap capacitor and an integrated circuit. The insulative sidewall of the pressure sensor includes a pressure sensitive diaphragm portion, and the gap capacitor includes a first electrode plate, which is attached to an interior surface of the diaphragm portion of the sidewall, and a second electrode plate, which is spaced apart from the first electrode plate and coupled to the integrated circuit, which is coupled, through the sidewall, to a supply contact and a ground contact. A conductive layer extends over one of the interior surface of the diaphragm portion of the sidewall and an exterior surface of the diaphragm portion; and the conductive layer is coupled to the ground contact to either shield or ground the first electrode plate.

System and method for making an antenna. An implantable medical device has a housing, a bobbin and a coil. The housing has an interior generally tubular cross-section with a longitudinal axis, the housing having a lateral portion of a segment of the tubular cross-section along the longitudinal axis. The bobbin has a first side nearest to the interior of the housing and a second side opposite the first side. The coil, wound around the bobbin on a winding axis orthogonal to the longitudinal axis of the tubular cross-section, has a greater number of complete turns proximate the second side of the bobbin than proximate the first side of the bobbin, with the coil having a cross-sectional shape selected for a space between the bobbin and the interior of the housing in the lateral portion of the segment of the tubular cross-section along the longitudinal axis of the housing.

A device includes a flexible substrate, N coiled conductors, and a plurality of folding regions. The N coiled conductors are deposited on the flexible substrate and connected in series by conductive interconnects. N is greater than 1. Each of the folding regions is defined by a separation distance between adjacent ones of the N coiled conductors. The conductive interconnects traverse the folding regions between the N coiled conductors to connect the N coiled conductors in series. The flexible substrate is folded such that the N coiled conductors form a stack of N coiled conductors.
