A system having a catheter having a distal pressure sensitive capacitive element providing an impedance and phase shift which varies responsive to the amount of pressure from blood external the catheter, a detector having electronics for determining the impedance and/or phase shift. This impedance and or phase shift corresponds to the pressure of the blood about the distal end of the catheter. When the catheter is inserted into a patient's body, the impedance or phase shift is detected quasi wirelessly without special signal communication means like optical fibers or electrical wires from outside the patient's body utilizing the patient as a ground path and the catheter shaft as an electrical conductor.

A system for detection of blood pressure in a blood vessel includes a guide wire and a LC resonance circuit provided at a distal end of the guide wire. The resonance circuit may be a non-LC resonance circuit responsive to changes in pressure of fluid external to the guide wire such that the resonance circuit has a resonance frequency that varies in accordance with changes in pressure of the external fluid.

Provided is a sample processing cartridge. The sample processing cartridge can include a housing and a channel disposed in the housing. The housing can include a sample inlet for receiving at least one biological sample. The channel can in fluidic communication with the sample inlet and can be defined by an upper surface and a lower surface. The upper surface can include a hydrophilic portion and a hydrophobic portion. The lower surface can include a hydrophilic portion and a hydrophobic portion. The hydrophilic and hydrophobic portions of the upper and lower surfaces of the channel can be configured to isolate at least one aqueous reagent.

A microfluidic system includes a microfluidic cartridge and an electromagnetic droplet actuator arranged proximate the microfluidic cartridge. The microfluidic cartridge includes a plurality of droplet wells with topological barrier structures between adjacent wells. The topological barrier structures are configured to allow magnetic particles and material attached to the magnetic particles to pass between adjacent wells while confining droplets within respective wells. The electromagnetic droplet actuator includes a plurality of electromagnetic components arranged to provide an electronically selectable magnetic field pattern to actuate movement of a plurality of magnetic particles when contained within at least one droplet in at least one of the plurality of droplet wells.
