Patent ID: 8900651

Claim:
A method of preparing a coated biomedical implant comprising: providing a biomedical implant; depositing on said biomedical implant a first layer comprising a hydrophobic polymer; depositing on said biomedical implant a second layer comprising an impermeable dispersed solid, wherein the impermeable dispersed solid and the hydrophobic polymer are discharged separately through a first and/or second orifice and wherein the impermeable solid is discharged through the first or second orifice as a dry powder and deposited in dry powder form, and sintering the first and second layers under conditions that do not substantially disrupt the activity and/or function of the biomedical implant thereby forming a coating, wherein the coating substantially seals the biomedical implant; and wherein the coating is substantially impermeable to a gas; the coating is substantially impermeable to a fluid; and the coating is substantially impervious to a biological material.
