Abstract: An integrated electronic chip including: a first section formed on a first substrate; a second section formed on a second substrate; and a chip package. The first section including a first electronic circuit electrically coupled to a first optical transmitter and a first optical receiver. The second section including a second electronic circuit electrically coupled to a second optical transmitter and a second optical receiver. The chip package configured to hold the first and second sections such that: the first substrate is separated from the second substrate by a gap having a predetermined width; first optical signals emitted by the first optical transmitter are received by the second optical receiver; and second optical signals emitted by the second optical transmitter are received by the first optical receiver. The first circuit is electrically isolated from the second circuit by the gap.

Abstract: A multilayer, thermally-stabilized substrate, including: a thermally-conductive core structure, including a central section located horizontally between two edge sections; a top multilayer circuit board connected to the top surface of the central portion of the core structure; and a bottom multilayer circuit board connected to the bottom surface of the central portion of the core structure. The core structure has a core thermal conductance and a effective core horizontal thermal expansion coefficient. The top and bottom multilayer circuit boards each include at least one dielectric layer and at least one electrically-conductive layer, and each have a circuit board thermal conductance that is less than the core thermal conductance of the core structure. The electrically-conductive layers of the top and the bottom circuit boards each have a conductive layer horizontal thermal expansion coefficient that is less than or equal to the effective core horizontal thermal expansion coefficient of the core structure.

Abstract: A transfer device usable in a system for intraluminal treatment of a selected site in a body of a patient in which the transfer device comprises an integral pump for pressurizing and circulating fluid through a fluid path defined by the transfer device and associated catheter. A removable fluid cartridge is provided including a reservoir from which fluid is drawn by the pump and into which fluid is returned after being circulated through the fluid path. The pump may be a peristaltic pump and the fluid cartridge may include an elongated fluid pick-up having an inlet through which fluid is introduced into the transfer device. The fluid pick-up is sized in length so that the inlet is always submerged in the fluid regardless of the orientation of the transfer device. A removable treatment cartridge having a lumen forming part of the fluid path may also be provided, and a storage sleeve for the treatment cartridge may be of a radiation-blocking material, such as quartz.
