Patients with spinal cord injuries have benefited from neurostimulation therapy comprising delivery of electrical stimulation to enable or excite neurological responses using an implantable neurostimulator having an electrode array. Dangerous levels of charge are avoided while providing multiple, simultaneous stimulation waveforms by inducing a short in an electrode when a monitored value reaches or exceeds a predetermined threshold.

Methods for neurostimulator pulse overlap control

Disclosed herein are methods for neurostimulation therapy for spinal cord injury. More particularly, the present invention relates to methods for neurostimulation therapy for spinal cord injury. More particularly, the present invention relates to methods for providing multiple independent, simultaneous waveforms in neurostimulation therapy while minimizing or substantially eliminating undesirable interactions between the waveforms.

Methods for providing optimized neurostimulation

A large volume preconcentrator device for concentrating analytes. A housing accepts an analyte vapor flow, and a plurality of collection surfaces are disposed within the housing. A selectively actuatable heater is disposed on each of the plurality of collection surfaces. At least one selectively actuatable damper is disposed within the housing for selectively restricting a collection flow.

Large volume analyte preconcentrator

An interchangeable preconcentrator assembly comprises an outer housing and an inner housing defining a chamber. A biased urging member is held at least partially within the outer housing and slidably biased toward a surface of the inner housing. When the biased urging member is at least partially retracted, a space is defined between the urging member and the surface of the inner housing for accommodating at least one preconcentrator chip. A continuous fluid flow path is defined through the outer housing and through the space. The interchangeable preconcentrator assembly may further comprise at least one modular preconcentrator carriage.
