Abstract
A drug delivery system that can be deployed from a catheter and retained within the bladder for delivery of treatment drug solutions over a period of time. The delivery system includes an inflatable or expandable delivery element that can be collapsed within the catheter tip for navigation into the bladder before being inflated or expanded within the bladder. The inflated or expanded delivery element can engage the bladder walls or sized to be too large to be passed from the bladder such that the delivery element is retained within the bladder after inflation or expansion to administer a treatment drug solution over an extended period of time.
Claims21
A drug delivery device for treating bladder disorders, comprising:
- a catheter having a lumen defined between a proximal end and a distal tip;
- and
- a delivery element having a non-expanded state and an expanded state,
- wherein the delivery element is contained within the lumen as the distal tip is navigated into a bladder;
- and
- wherein the delivery element transitions to the expanded state when the delivery element is advanced out of the lumen such that the delivery element contacts an internal bladder wall to deliver a treatment drug from the delivery element to the bladder,
- wherein the delivery element is separable from the catheter.
A method for delivering a bladder treatment drug, comprising:
- providing a catheter having a lumen defined between a proximal end and a distal tip, the catheter including a delivery element within the lumen;
- advancing the delivery element out of the lumen such that the delivery element assumes an expanded disposition within a bladder, wherein the delivery element is in contact with an internal bladder wall;
- separating the delivery element from the catheter within the bladder;
- and
- delivering a bladder treatment drug to the internal bladder wall through contact of the delivery element with the internal bladder wall.
