Microdevice the diagnosis and in vivo therapy.

摘要

A micro-diagnostic or -therapeutic instrument comprises a body which has a main channel (24) extending along it, with an inlet (18) at the near end (14) and an outlet at the far end (20), and electrodes (10) are located externally, with connection pads (16) at the inlet end. A micro-diagnostic or -therapeutic instrument comprises a body which has a main channel (24) extending along it, with an inlet (18) at the near end (14) and an outlet at the far end (20), and electrodes (10) are located externally, with connection pads (16) at the inlet end. Secondary channels (26, 28) connect laterally between the main channel and side outlets (22). The pads are in micro-cavities formed in the body. Their height and width are between 10 Microm and 50 Microm. The maximum external dimension of the cross section is less than 1 mm. The section is rectangular or square. Each side is less than 300 Microm or 900 Microm. The length is 0.5-3 cm. The main channel inlet is funnel-shaped. The body is silicon. A waveguide is included.
