SYSTEMS, METHODS, AND DEVICES FOR EVALUATING LEAD PLACEMENT BASED ON PATIENT PHYSIOLOGICAL RESPONSES

摘要

A pulse generator is programmed to generate electrical stimulation to target a sacral nerve or a pudendal nerve of the patient. The electrical stimulation being delivered at least in part via a lead. The electrical stimulation is applied by ramping up a stimulation parameter over time. A first, a second, and a third physiological response are detected from the patient as a result of the electrical stimulation. A first value, a second value, and a third value of the stimulation parameter associated with the first, second, and third physiological response are measured, respectively. A placement of the lead inside the patient is evaluated based on at least one of: a chronological sequence in which the first, second, and third physiological responses occurred, a comparison of the first value with a predetermined threshold, or respective deviations of the second value or the third value from the first value.

1. A portable electronic programmer, comprising:
an electronic memory storage configured to store programming instructions; and one or more processors configured to execute the programming instructions to perform the following steps:
programming a pulse generator to generate electrical stimulation to target a sacral nerve or a pudendal nerve of the patient, the electrical stimulation being delivered via a lead, the electrical stimulation being applied by ramping up a stimulation parameter over time;detecting a first physiological response, a second physiological response, and a third physiological response from the patient as a result of the electrical stimulation;measuring a first value of the stimulation parameter associated with the first physiological response, a second value of the stimulation parameter associated with the second physiological response, and a third value of the stimulation parameter associated with the third physiological response; andevaluating a placement of the lead inside the patient based on at least one of: a chronological sequence in which the first, second, and third physiological responses occurred, a comparison of the first value with a predetermined threshold, or respective deviations of the second value or the third value from the first value.
