SELECTIVE NERVE STIMULATION USING PRESYNAPTIC TERMINAL DEPLETION BLOCK

摘要

An example of a system may include a stimulator and at least one controller. The stimulator may be configured to deliver nerve stimulation to capture a first set of axons in a nerve and to deliver depletion block stimulation to capture a second set of axons in the nerve, where the second set is a subset of the first. The depletion block stimulation may include a series of pulses at a depletion pulse frequency within a range between about 100 Hz to about 1 kHz, and the nerve stimulation may include a series of pulses at a stimulation pulse frequency within a range of about 0.25 Hz to about 50 Hz. At least a portion of the nerve stimulation and at least a portion of the depletion block stimulation may be delivered to be effective in providing a nerve block while delivering nerve stimulation.

1. A system, comprising:
a stimulator configured to deliver nerve stimulation to capture a first set of axons in a nerve and to deliver depletion block stimulation to capture a second set of axons in the nerve, the second set of axons being a subset of the first set of axons, the depletion block stimulation including a series of pulses at a depletion pulse frequency within a range between about 100 Hz to about 1 kHz, the nerve stimulation including a series of pulses at a stimulation pulse frequency within a range of 0.25 Hz to 50 Hz; and at least one controller configured to communicate with the stimulator and control the depletion block stimulation and the nerve stimulation, at least a portion of the nerve stimulation and at least a portion of the depletion block stimulation being delivered to be effective in providing a nerve block while delivering nerve stimulation.
