Abstract
An autoinjector device and a method of use thereof for perispinal administration, comprising: a housing with an interspinous stop; a syringe assembly slidably mounted on the housing, the syringe assembly including a needle and a fluid container; an autoinjector actuator for urging the syringe assembly with respect to the housing from a storage position to a launch position wherein the needle travels through the interspinous stop; and a cap releasably engaged to the housing.

A perispinal injector device for injecting a fluid, comprising a medicine, between adjacent spinous processes of a patient, comprising:
- a housing;
- a syringe assembly that is slidably mounted on the housing;
- wherein the syringe assembly comprises a needle;
- an interspinous stop designed to facilitate positioning the needle over an interspinous space;
- wherein the interspinous stop defines an aperture for deployment of the needle;
- wherein the interspinous stop defines a bottom surface of the device for contacting skin;
- wherein the interspinous stop has a side surface that is either flat or concave;
- wherein the interspinous stop is dimensioned so that, when the bottom surface contacts the skin and the side surface of the interspinous stop is pressed against a spinal process of the patient, and the needle is deployed, the needle enters the skin in a region between the spinous processes of two adjacent vertebrae of the patient.
A method of perispinal administration of medicine, comprising:
- contacting a bottom surface of an interspinous stop, designed to facilitate positioning a needle over an interspinous space, to skin of a patient;
- pressing a flat or concave side surface of the interspinous stop against a spinal process of one vertebrae of the patient;
- while the flat or concave side surface of the interspinous stop is pressed against the spinal process and the bottom surface is in contact with the skin, passing a tip of a needle through an aperture in the bottom surface of the interspinous stop and into the patient until the needle extends beyond the bottom surface between 6 and 25 millimeters, without hitting bone;
- and
- while the tip of the needle is in the patient, injecting the medicine into the patient.
A method of perispinal administration of a medicine, comprising:
- using an interspinous stop to align a needle relative to a spinous process of a patient, so the needle will avoid hitting bone upon entering the patient;
- while aligned, inserting the needle into the patient between adjacent spinous processes;
- injecting, through the needle and into a patient, a volume of between 1.5 and 4 milliliters of fluid containing the medicine.
