Patent number: 8911426Abstract: An implantable drug delivery device that uses multiple reservoir elements to contain and release doses of active pharmaceutical ingredients. The device includes a first shell element, which has a first enclosed cavity volume and forms a low-permeability barrier. The first shell element is configured to absorb light irradiation from a laser source, the laser irradiation causing a breach in the first shell element. A first active pharmaceutical ingredient is contained in the first enclosed cavity volume and is released when the first shell element is breached. The device also includes a second shell element, which has a second enclosed cavity volume and also forms a low-permeability barrier. A second active pharmaceutical ingredient is contained in the second enclosed cavity volume. The device also includes an envelope element containing the first and second shell elements.Type: GrantFiled: February 8, 2011Date of Patent: December 16, 2014Assignee: On Demand Therapeutics, Inc.Inventors: Jonathan Robert Coppeta, Kenneth N. Horne, John T. Santini, Jr., John A. Scholl, Gregory J. R. Spooner, Cynthia L. Stevenson, Naveed Shams, Andrew Poutiatine

Publication number: 20140148792Abstract: Devices and methods are provided for selectively delivering a drug by laser activation. The device includes structural elements forming a hermetic, enclosed reservoir, and at least one drug unit contained in the enclosed reservoir. The at least one drug unit includes a drug. The device is able to absorb laser irradiation effective to open the enclosed reservoir to permit release of the drug. The method includes implanting a drug delivery device into a tissue site of a patient, and irradiating at least a portion of the drug delivery device to breach the enclosed reservoir to permit the drug to be released in tissues at the tissue site.Type: ApplicationFiled: February 3, 2014Publication date: May 29, 2014Applicant: On Demand Therapeutics Inc.Inventors: Jonathan R. Coppeta, Robert Dyer, Vipul Taneja, John T. Santini, JR.

Publication number: 20140135712Abstract: Devices and methods are provided for visualizing the opening of a drug reservoir of an implantable medical device. The disclosure provides methods for observing the release or exposure of contents from a drug reservoir of a medical device placed within the vitreous of an eye of a subject. The methods include implanting a drug delivery device within an anatomy of a subject. The device includes a plurality of reservoirs, each loaded with a therapeutic agent and a marker, and a plurality of barrier layers for separating the contents of the reservoirs from the anatomy. The method further includes irradiating at least one of the barrier layers such that at least one of the reservoirs is breached, thereby triggering release of the therapeutic agent and the marker from the device. By visually detecting release of the marker into the anatomy, release of the therapeutic agent into the anatomy is verified.Type: ApplicationFiled: January 21, 2014Publication date: May 15, 2014Applicant: On Demand Therapeutics, Inc.Inventors: Kenneth N. Horne, Gregory J.R. Spooner, John A. Scholl, John T. Santini, JR.

Patent number: 8597680Abstract: Methods and systems are provided for making a drug microtablet. The method includes loading a lyophilization capillary channel with a liquid drug solution; lyophilizing the liquid drug solution in the lyophilization capillary channel to produce a lyophilized drug formulation; compressing the lyophilized drug formulation in the lyophilization capillary channel, or in a compression capillary channel, to form a microtablet; and ejecting the microtablet from the lyophilization capillary channel or compression capillary channel. The methods and systems may provide drug microtablets having improved content uniformity and reduced weight variability.Type: GrantFiled: November 8, 2012Date of Patent: December 3, 2013Assignee: On Demand Therapeutics, Inc.Inventors: Jonathan R. Coppeta, Robert Dyer, Cynthia L. Stevenson
