Abstract
One aspect of the present disclosure relates to a system for treating a medical condition in a patient. The system can include a neurostimulator that is in electrical communication with a remote transducer. The neurostimulator can be sized and dimensioned for injection or insertion into a pterygopalatine fossa (PPF) of a patient. The remote transducer, when activated and brought into close proximity to the patient's head, can cause the neurostimulator to deliver an electrical signal to a target neural structure located within the PPF to treat the medical condition.
Claims20
A system for treating a medical condition in a patient comprising:
- a sheath having an inner lumen with a proximal end and a distal end;
- a neurostimulator sized and dimensioned for injection or insertion into the pterygopalatine fossa (PPF) of a patient, the neurostimulator comprising a plurality of expandable electrical leads each comprising a plurality of independently selectable electrical contacts, the plurality of expandable electrical leads disposed within the sheath's inner lumen in a non-deployed configuration and splaying radially outward from the distal end of the sheath's inner lumen in a deployed configuration;
- and
- a remote transducer that electrically communicates with and transfers power to the neurostimulator and when activated and brought into close proximity to the patient's head causes the neurostimulator to deliver an electrical signal to a target neural structure located within the PPF to treat the medical condition.
A method for treating a medical condition in a patient, the method comprising the steps of:
- inserting or injecting a sheath into a pterygopalatine fossa (PPF) of the patient, the sheath having an inner lumen with a proximal end and a distal end, the sheath having disposed therein a neurostimulator comprising a plurality of expandable electrical leads each comprising a plurality of independently selectable electrical contacts;
- advancing the sheath to a target neural structure in the PPF;
- deploying the plurality of expandable electrical leads to splay outwards from the sheath and fully or partially encapsulate the target neural structure;
- and
- activating one or more of the plurality of independently selectable electrical contacts to deliver a therapeutic electrical signal to the target neural structure to treat the medical condition.
