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.

The present disclosure generally relates to devices, systems, and methods for Fallopian tube diagnostics. In some embodiments a tube may have a distal end, and a balloon may have a first end coupled to the distal end of the tube. The balloon may be disposed in the tube in a first, inverted position, may be movable to a second, everted position, and may be extendable a distance distal of the tube. An extending portion may have a proximal end coupled to a second end of the balloon. The extending portion may be disposed within the balloon in the first inverted position, and may be extendable from the second end of the balloon in the second everted position.

Aspects of this disclosure relate to catheter assemblies, that include an inner tube component, an outer tube component that fits over the inner tube component, and a disposable layer of film that isolates the otherwise fluid-exposed portions of the catheter from the fluid it drains. This disposable film can be removed at regular intervals and obviates the need for catheter exchanges as the isolating disposable film, rather than the catheter itself, is removed. The principal characteristic of the disposable film is that it is relatively impermeable to fluid, for example, bodily fluids.

An everting balloon system is disclosed that can be used for the placement of an IUD within the uterine cavity of a female patient. The everting balloon system with IUD can be used to access a uterine cavity at specific locations in the fundus. A one-handed IUD delivery system for placement with an everting catheter is disclosed. An IUD loading system for placement within an everting catheter is disclosed. The everting catheter with an IUD can simplify the process of IUD placement within the uterine cavity.

A catheter that has a catheter tube everting inside-out during the process of catheterization. The catheter tube has a plurality of longitudinal protrusions extending from the first end of the catheter tube through at least a portion of the catheter tube, and forming an angle of 0 degrees to 45 degrees with respect to the longitudinal axis of the catheter tube and facing radially inwards, and provides for dilating a circumference of the catheter tube upon everting the catheter tube inside-out from the first end of the catheter tube.

Mechanical thrombectomy apparatuses, and particularly knitted rolling tube mechanical thrombectomy apparatuses configured to have improved tracking for delivery through tortious vessels are described herein. Also described herein are methods of removing clots using a mechanical thrombectomy apparatuses in which the clot is larger than the tractor portion of the mechanical thrombectomy apparatus.

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.

Provided is a system for advancing an article along a path. The system may include a head member; a dispatching member, and an eversion sleeve configured with an inverted portion having a sleeve end configured to be fixed to the dispatching member. The system may also include an everting portion configured for articulating to the head member and an un-inverted portion configured to extend from the everting portion towards the dispatching member, at least partially within the inverted portion.

A catheter may include a tubular member having a lumen and an outer surface, a sleeve configured to be positioned in the lumen in a retracted configuration and to evert over at least a portion of the outer surface in an everted configuration, and a filament configured to retract the sleeve into the retracted configuration. The catheter may include an aperture proximal of a distal end, where the filament extends through the aperture from the lumen. A pull member may be on a distal end of the filament. The filament may be looped, coiled, and/or bunched in the catheter when the sleeve is in the retracted configuration. A shuttle may be attached to a distal end of the sleeve, where the shuttle includes a tubular member configured to maintain patency of the sleeve, and the filament engages the shuttle to retract the sleeve into the lumen.

Apparatus for inverting an elongated flexible tubular sleeve having a proximal end, a distal end and a central lumen extending between the proximal end and the distal end, the apparatus comprising: a hollow tube comprising a proximal end, a distal end and a central lumen extending between the proximal end and the distal end; and an elongated rod movably disposed within the central lumen of the hollow tube, the elongated rod having a proximal end and a distal end, wherein the distal end of the elongated rod comprises a sleeve plug for securing a distal end of an elongated flexible tubular sleeve to the distal end of the hollow tube; wherein, when the elongated flexible tubular sleeve is disposed over the hollow tube, (i) the sleeve plug of the elongated rod is configured to be moved proximally to clamp the distal end of the elongated flexible tubular sleeve to the distal end of the hollow tube, and (ii) the sleeve plug of the elongated rod is configured to be moved distally to release the distal end of the elongated flexible tubular sleeve from the distal end of the hollow tube;

and further wherein when the distal end of the elongated flexible tubular sleeve is clamped to the distal end of the hollow tube, the proximal end of the elongated flexible tubular sleeve can be pulled toward the distal end of the hollow tube to invert the elongated flexible tubular sleeve.
