Embodiment Construction

[0043] Improved drug delivery devices, systems and methods have been developed for the controlled delivery of drugs to selected regions of the lower urinary tract of catheterized patients, such as the bladder. The drug delivery device may be used with a urinary catheter, such as a Foley catheter, which together form a urinary catheter and drug delivery system. The drug delivery device advantageously includes a drug reservoir that remains outside the patient's body during use of the device and is configured to be capable of functioning as an osmotic pump to push drug from the drug reservoir through a flexible elongated lumen body (e.g. , capillary), the flexible elongated lumen body extends along or through the catheter for releasing the drug into the bladder. The location of the drug depot outside the patient's body advantageously allows the drug delivery device to include a sufficiently large drug payload for drug delivery over an extended period of time while minimizing inte...

Abstract

Drug delivery devices (200) and methods of their use are provided. In one embodiment, a drug delivery device (200) for use with a urinary catheter (100) includes a drug reservoir configured to be disposed outside of a patient's body, and a flexible elongate body (220) attached to the drug reservoir (230) and configured to traverse the patient's urethra to reach the bladder. The drug reservoir (230) includes a drug chamber (234) containing a drug therein, a fluid chamber (236) containing a fluid therein, and an osmotic barrier (238) separating the drug chamber (234) and the fluid chamber (236).The body includes a drug delivery lumen (222) extending therethrough and in fluid communication with the drug chamber (234).

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to U.S. Provisional Patent Application 62 / 584,006, filed November 9, 2017, which is incorporated herein by reference. technical field [0003] The present application relates generally to medical devices and methods, and more particularly to drug delivery devices and related methods of using such devices for the controlled delivery of drugs to selected regions of the lower urinary tract of catheterized patients, such as the bladder. Background technique [0004] Various drug delivery devices and methods have been developed for delivering drugs to the lower urinary tract of a patient. For example, certain drug delivery devices may be implanted and retained in a patient's bladder and configured to release a drug therein in a controlled manner over an extended period of time to treat a variety of conditions. However, it may be impractical or even impossible to use such dru...
