Implantable drug delivery system

Abstract

An implantable medicament delivery device includes a core body which further includes a single basin or multiple smaller basins for containing a drug or a medicament. Each basin is covered by a screen. The implantable drug delivery device is placed within the body of an animal, and the drug is allowed to diffuse through the holes in the screen to provide treatment of a disease or condition.

1 . A method of making implantable drug delivery platform comprising the steps of:
 a) forming a basin containment portion around a basin, said basin being constructed and arranged to contain the drug;   b) affixing a first screen to said basin containment portion to cover said basin.   
     
     
         2 . The method as defined in  claim 1  further including the step of placing a second screen on the opposite side of said basin. 
     
     
         3 . The method as defined in  claim 2  wherein said second screen is affixed to said basin containment portion. 
     
     
         4 . The method as defined in  claim 1  wherein said basin containment portion is substantially planar. 
     
     
         5 . The method as defined in  claim 1  wherein said first screen is formed to be substantially planar. 
     
     
         6 . The method as defined in  claim 2  wherein said second screen is formed to be substantially planar. 
     
     
         7 . The method as defined in  claim 1  wherein the combination of said basin containment portion and said screen are formed to encircle an internal body part. 
     
     
         8 . The method as defined in  claim 1  wherein the step of forming said screen is further defined by forming the number and size of the holes in said screen depending on one or more factors selected from a group including medicament solubility, medicament dissolution rate, and medicament concentration. 
     
     
         9 . The method as defined in  claim 1  further including the step of dividing said basin into at least two smaller basins. 
     
     
         10 . The method as defined in  claim 9  further including the step of forming the size and number of the holes in said screen covering said smaller basins. 
     
     
         11 . A method of treating a disease within the eye of an animal, said method comprising the steps of:
 making an incision in the sclera;   inserting a drug delivery device through said incision, said drug delivery device including:
 a basin containment portion including a basin constructed and arranged to contain the drug; 
 a screen constructed and arranged to cover said basin and be affixed to said basin containment portion. 
   
     
     
         12 . The method as defined in  claim 11  the opposite sides of said basin is formed as a screen. 
     
     
         13 . The method as defined in  claim 11  wherein said basin passes through said basin containment portion and on the bottom of said basin is a second screen, said second screen being constructed and arranged to cover the basin and be affixed to said basin containment portion. 
     
     
         14 . The method as defined in  claim 11  wherein said basin containment portion is substantially planar. 
     
     
         15 . The method as defined in  claim 11  wherein said screen is substantially planar. 
     
     
         16 . The method as defined in  claim 13  wherein said second screen is substantially planar. 
     
     
         17 . The method as defined in  claim 11  wherein the size of the holes in said screen is dependent on one or more factors selected from a group including medicament solubility, medicament dissolution rate, and medicament concentration. 
     
     
         18 . The method as defined in  claim 13  wherein the number and size of the holes in said second screen is dependent on one or more factors selected from a group including medicament solubility, medicament dissolution rate, and medicament concentration. 
     
     
         19 . The method as defined in  claim 11  wherein said well in said basin containment portion is divided into at least two smaller basins. 
     
     
         20 . The method as defined in  claim 17  wherein the size and number of the holes in said screen covering said smaller basins are different.
