Abstract
A method and device for treating a mammalian organism to obtain a desired local or systemic physiological or pharmacological effect is provided. The method includes administering a sustained release drug delivery system to a mammalian organism in need of such treatment at an area wherein release of an effective agent is desired and allowing the effective agent to pass through the device in a controlled manner. The device includes an inner core or reservoir including the effective agent, an impermeable tube which encloses portions of the reservoir, and a permeable member at an end of the tube.
Claims20
A method for treating a mammal to obtain a desired local or systemic physiological or pharmacological effect, comprising administering to the mammal a sustained release drug delivery system, wherein:
- (i) the system comprises:
- a drug reservoir comprising a therapeutically effective amount of an agent;
- an inner tube covering at least a portion of the drug reservoir, wherein the inner tube has a first open end and a second open end, the diameter of the inner tube is not more than 3 millimeters, and the inner tube is dimensionally stable and capable of supporting its own weight;
- and
- an outer layer, covering a portion of the inner tube, wherein the outer layer is permeable to the passage of the agent;
- and
- (ii) upon administering the system, the agent is released through at least one of the first open end and second open end.
A method for treating a human to obtain a desired local or systemic physiological or pharmacological effect, comprising administering to the human a sustained release drug delivery system, wherein:
- (i) the system comprises:
- a drug reservoir comprising a therapeutically effective amount of an agent;
- an inner tube covering at least a portion of the drug reservoir, wherein the inner tube has a first open end and a second open end, the diameter of the inner tube is not more than 3 millimeters, the length of the inner tube is not more than 7 millimeters, and the inner tube is dimensionally stable and capable of supporting its own weight;
- and
- an outer layer, covering a portion of the inner tube, wherein the outer layer is permeable to the passage of the agent;
- (ii) administering comprises inserting the system into the vitreous of the eye;
- and
- (iii) upon administering the system, the agent is released through at least one of the first open end and second open end.
