Method and apparatus for injecting a neurotoxin into a localized area

Abstract

A syringe assembly for administration of a neurotoxin, the syringe assembly comprising: a syringe comprising: a clear syringe barrel with dosage markings completely encircling the clear syringe barrel; and a plunger having a plunger body and a clear inverted plunger tip; and a needle assembly comprising a needle and a sealing hub for removably attaching the needle assembly to the syringe, wherein the needle is approximately 0.15 inches to approximately 0.3 inches in length and has a gauge of approximately 27 gauge to approximately 35 gauge.

1 .- 23 . (canceled) 
     
     
         24 . A syringe for administration of a neurotoxin, the syringe comprising:
 a clear syringe barrel with dosage markings completely encircling the clear syringe barrel, wherein each of the dosage markings is visible to a clinician when the clear syringe barrel is oriented at any rotational angle relative to a longitudinal axis thereof; and   a plunger having a plunger body, an inverted plunger tip, and a marking disposed at a junction between the plunger body and clear inverted plunger tip, the marking comprises a color that is visible to the clinician through the clear syringe barrel from an exterior of the syringe assembly and has a contrasting appearance relative to each of the dosage markings.   
     
     
         25 . The syringe of  claim 24 , wherein the syringe is a 1.0 cc syringe. 
     
     
         26 . The syringe of  claim 24 , wherein the dosage markings are cc markings. 
     
     
         27 . The syringe of  claim 24 , wherein the dosage markings are unit markings. 
     
     
         28 . The syringe of  claim 24 , wherein the unit markings are derived based on dilution of a medicament to be delivered by said syringe assembly. 
     
     
         29 . The syringe of  claim 24 , wherein the dosage markings are both unit markings and cc markings. 
     
     
         30 . The syringe of  claim 24 , wherein said inverted tip is clear. 
     
     
         31 . The syringe of  claim 24 , wherein the plunger body is clear. 
     
     
         32 . The syringe of  claim 24 , wherein the plunger body is opaque. 
     
     
         33 . The syringe of  claim 24 , wherein the plunger body and inverted tip are different colors. 
     
     
         34 . The syringe of  claim 24 , further comprising a needle assembly comprising a needle and a sealing hub for removably attaching the needle assembly to the syringe, wherein the needle is approximately 0.15 inches to approximately 0.3 inches in length and has a gauge of approximately 27 gauge to approximately 35 gauge. 
     
     
         35 . The syringe of  claim 34 , wherein the needle is 0.25 inches in length. 
     
     
         36 . The syringe of  claim 34 , wherein the needle is 33 gauge. 
     
     
         37 . The syringe of  claim 24 , wherein the marking enhances visual distinction between the plunger body and the inverted plunger tip. 
     
     
         38 . The syringe of  claim 24 , wherein the neurotoxin is botulinum toxin. 
     
     
         39 . The syringe of  claim 24 , wherein thickness of said dosage markings is graduated from lowest dosage to highest dosage. 
     
     
         40 . The syringe of  claim 24 , wherein darkness of said dosage markings is graduated from lowest dosage to highest dosage.
