High-frequency couplers and coupling techniques are described utilizing artificial composite right/left-handed transmission line (CRLH-TL). Three specific forms of couplers are described; (1) a coupled-line backward coupler is described with arbitrary tight/loose coupling and broad bandwidth; (2) a compact enhanced-bandwidth hybrid ring coupler is described with increased bandwidth and decreased size; and (3) a dual-band branch-line coupler that is not limited to a harmonic relation between the bands. These variations are preferably implemented in a microstrip fabrication process and may use lumped-element components. The couplers and coupling techniques are directed at increasing the utility while decreasing the size of high-frequency couplers, and are suitable for use with separate coupler or couplers integrated within integrated devices.

Transillumination imaging instrumentation is improved by eliminating the detection of stray light beams, and facilitating the detection of light beams which pass straight through an illuminated object. Three dimensional images can be constructed using either curved emitter and detector arrays or by using emitter and detector elements that rotate about a common axis.

A connector assembly for detachably coupling a proximal end of a lead and an implantable medical device. The connector assembly includes a deflectable connector clip having a first arm, a second arm and a top portion extending between the first arm and the second arm. The first arm and the second arm detachably position the proximal end of the lead within the implantable medical device. A housing portion has a first deflection portion that deflects the connector clip from a first position corresponding to a first distance between the first arm and the second arm, to a second position corresponding to a second distance between the first arm and the second arm. Subsequent advancement of the lead through the first and second arms further deflects the connector clip from the second position to a third position, which transfers all of the spring force of the connector clip to the lead.
