  • Publication number: 20180140748
    Abstract: Abstract of the Disclosure 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.

  • Publication number: 20180071213
    Abstract: 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.

  • Publication number: 20170165460
    Abstract: 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.

  • Patent number: 9561353
    Abstract: Implant devices for intravesical administration and local drug delivery. The device has a body which includes a hollow tube formed of a biocompatible material; at least one reservoir in the tube which contains a drug; and one or more apertures through which the drug can be released. The device is configured for minimally invasive insertion into a body cavity, such as the bladder. The hollow tube may be elastomeric to permit the device to be elastically deformed from its initial shape into an elongated shape for passage through a catheter, where following such passage the device can return to or toward its initial shape to facilitate retention of the device in the body cavity. The body may have a narrow, elongated shape effective to permit insertion of the drug delivery device through a catheter without necessarily deforming the body, yet include flexible projections which effect retention within the body cavity.

  • Publication number: 20160339217
    Abstract: 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.
