Patent number: 11696830Abstract: Implantable drug-eluting device (1) comprising a microporous structure (2) having regularly arranged pores (4, 5) in at least two different uniform sizes, and manufacturing method. The pores are configured for receiving a drug (9) and are being connected by interconnections (6, 7). Interconnections (6) originating from pores (4) of a first size have a first elution area and interconnections (7) originating from pores (5) of a second size have a second elution area. The interconnections convey the drug (9) to a surface of the device for elution to surrounding tissue. The ratio between the first and the second elution areas is predefined and selectable. The differently sized elution areas provide for different outflow rates. This allows for simple but reliable dispensing of drugs at positively controlled and well determined rates. Particularly, this enables a single implantable device to dispense drugs over preselectable durations of time, like short-term or long-term.Type: GrantFiled: October 11, 2018Date of Patent: July 11, 2023Assignee: Waldemar Link GmbH & Co.
