Abstract
A method (and the resulting product) of making a medical implant device for releasing self-contained drugs on a controlled basis wherein the method utilizes, at least in part, computer-controlled 3-D printing equipment to deposit via nozzles portions of one or more layers of the medical implant product. The implant has an outer impervious coating, an inner matrix core, an opening and an optional bonding layer.
Claims12
A multi-step method of making a mammalian subcutaneous medical implant for releasing self-contained drugs on a controlled basis over at least a 3 day period wherein the method comprises depositing at least portions of one or more individual layers of the implant by at least one computer controlled 3-D printer, wherein the method comprises a first step of supplying a sheet of prefabricated coating material.
A multi-step method of making a mammalian subcutaneous medical implant for releasing self-contained drugs on a controlled basis over at least a 3 day period wherein the method comprises depositing at least portions of one or more individual layers of the implant by at least one computer controlled 3-D printer, wherein a matrix core layer is created, in whole or in part, within a separate chamber.
A multi-step method of making a mammalian subcutaneous medical implant for releasing self-contained drugs on a controlled basis over at least a 3 day period wherein the method comprises depositing at least portions of one or more individual layers of the implant by at least one computer controlled 3-D printer, wherein more than one implant is formed at the same time, and wherein one or more layers of each of the implants are created at least in part by 3-D printing.
A subcutaneous medical implant for releasing self-contained drugs on a controlled basis over at least a 3 day period wherein its method of manufacture involves, at least in part, the use of at least one computer controlled 3-D printer to deposit portions of one or more individual layers of the implant, wherein at least one layer of the implant is a sheet of prefabricated coating material.
A subcutaneous medical implant for releasing self-contained drugs on a controlled basis over at least a 3 day period wherein its method of manufacture involves, at least in part, the use of at least one computer controlled 3-D printer to deposit portions of one or more individual layers of the implant, wherein more than one implant is formed at the same time and wherein one or more layers of each of the implants are created at least in part by 3-D printing.
