Embodiments of the present disclosure comprise occlusion and drug delivery devices and methods. One aspect of the disclosure comprises a drug delivery device comprising an inner expansion member and an outer drug delivery component. Another aspect of the disclosure comprises bioabsorbable, lumen-occluding implants.

Everting balloon systems and methods for using the same are disclosed herein. The systems can be configured to access and dilate body lumen and cavities. For example, the systems can be used to dilate the cervix and access the uterine cavity. The systems can also be used to occlude the cervix. The systems can also be used to occlude the urethra.

A device and system for thermally affecting tissue that includes a balloon catheter with a reduced distal length for ease of navigation and that also includes a balloon that is more resistant to bursting and delamination. The balloon may include a proximal neck generally attached to an elongate body and a distal neck generally attached to a shaft disposed within the elongate body. The distal neck is turned inward to extend within the balloon chamber and the proximal neck may either extend within the chamber or extend proximally away from the balloon chamber. Alternatively, the device may include an inner balloon and an outer balloon, the distal necks of both being turned inward and extending within the inner balloon chamber. The proximal necks may both also be turned inward to extend within the chamber or the proximal neck of the outer balloon may extend away from the balloon chamber.

An example catheter includes an elongated member configured to be navigated through vasculature of a patient to a target treatment site in a vessel of the patient, a needle positioned at a distal portion of the elongated member, the needle configured to be within the elongated member when in a delivery configuration and radially extended to puncture a vessel wall of the vessel at the target treatment site when in a deployed configuration, and an expandable balloon including a needle guide configured to position a distal end of the needle at a predetermined distance from a central axis of the elongated member when the balloon is in an expanded configuration and the needle is in the deployed configuration.

A catheter system having an intussuscepting balloon and a handle for a catheter system. The handle includes a fluidic system for preventing overpressure conditions during balloon intussuscepting and includes a locking mechanism disposed outside of the fluidic system for preventing unintended or accidental movements of a plunger assembly included in the fluidic system. The system includes standard sized components and non-standard sized components. During handle assembly, specific sizes of non-standard sized components are selected to match the length and/or the diameter of a specific selected balloon and are assembled with the standard sized components to form the catheter system.

A catheter includes a rolling membrane defining an inner volume that can be pressurized. The rolling membrane is configured to roll out in a longitudinal direction (D) into a rolled-out state. An inner shaft is attached to the rolling membrane. The membrane can roll out in a longitudinal direction along a vessel of a patient.
