Implantable drug delivery devices include a housing defining a reservoir, a first unit within the reservoir, and a second unit within the reservoir. The first unit contains a drug and the second unit contains a functional agent that facilitates release of the drug. Intravesical drug delivery devices include a housing portion containing a drug formulation and a housing portion containing an excipient, and are configured to release the drug according to a first release profile and the excipient according to a second release profile. Methods include inserting any of these devices into a patient and releasing drug from the device.

Multi-unit drug delivery devices and methods

Implantable drug delivery devices include a housing having a closed drug reservoir lumen bounded by a first wall structure and a hydrophilic second wall structure, and a drug contained in the drug reservoir lumen, wherein the first wall structure is impermeable to the drug and the second wall structure is permeable to the drug. Methods of providing controlled release of drug to a patient include deploying a drug delivery device in the patient releasing a drug from the drug reservoir lumen via diffusion through the second wall structure.

Drug delivery devices with drug-permeable component and methods

A drug dosage form is provided in the form of a solid tablet which is greater than 50% by weight the local anesthetic agent. The local anesthetic agent may be selected from the group consisting of an aminoamide, an aminoester, and a combination thereof. The drug tablet may be in the form of a mini-tablet which is greater than 70 wt % drug, with the balance being excipient. For example, the anesthetic agent may include lidocaine, in a salt or base form, combined with binder and lubricant excipients. Implantable drug delivery devices including the tablets are also provided, e.g., one or more of the drug tablets may be contained in a biocompatible housing. The drug tablets may be substantially cylindrical with flat end faces, and the device may have from 10 to 100 drug tablets aligned in the housing with the flat end faces of adjacent tablets abutting one another.

Solid drug tablets for implantable drug delivery devices

Implantable devices and methods for delivery of lidocaine or other drugs to a patient are provided. In one embodiment, the device includes a first drug portion which has a first drug housing which contains a first drug formulation in a solid form which includes a pharmaceutically acceptable salt of lidocaine; and a second drug portion which includes a second drug housing which contains a second drug formulation which includes lidocaine base. In another embodiment, the device includes a drug reservoir component which has an elastic tube having at least one lumen bounded by a porous sidewall having an open-cell structure, a closed-cell structure, or a combination thereof; and a drug formulation contained within the at least one lumen, wherein the device is deformable between a low-profile deployment shape and a relatively expanded retention shape.

Intravesical device for controlled drug delivery

Intravesical drug delivery devices are provided which may include an elongated body formed of a matrix system of a drug dispersed in a silicone, wherein the elongated body has a first end, an opposed second end, and an intermediate portion between the first and second ends, and wherein the silicone of the matrix system is cured to bias the elongated body in a coiled retention shape, such that the device is elastically deformable between a relatively straightened shape suited for insertion of the device through a urethra and into the urinary bladder of a patient and the coiled retention shape which is suited to retain the device within the urinary bladder.

Intravesical drug delivery devices and methods including elastic polymer-drug matrix systems

Drug delivery devices are provided in which much of a drug payload within the device remains within an area proximal to a wall of the device through which the drug must pass for release of the drug from the device into a patient. In one case, the device may include a drug reservoir portion which has a drug reservoir lumen bounded by a reservoir wall having an inner surface; a drug located in the drug reservoir lumen; and a core region which does not comprise the drug, wherein the drug is disposed between the inner surface of the reservoir wall and the core region. The device may be elastically deformable between a first shape suited for insertion through a lumen into a body cavity of the patient and a second shape suited to retain the device within the body cavity.

The local anesthetic agent may be selected from the group consisting of an aminoamide, an aminoester, and a combination thereof. The drug tablet may be in the form of a mini-tablet which is greater than 70 wt % drug, with the balance being excipient. For example, the anesethetic agent may include lidocaine, in a salt or base form, combined with binder and lubricant excipients. Implantable drug delivery devices including the tablets are also provided, e.g., one or more of the drug tablets may be contained in a biocompatible housing. The drug tablets may be substantially cylindrical with flat end faces, and the device may have from 10 to 100 drug tablets aligned in the housing with the flat end faces of adjacent tablets abutting one another.
