The invention provides an inflatable insertion device capable of being percutaneously introduced into a patient's body. The insertion device comprises an inflatable element having a distal end and a proximal end and which is operable between a collapsed condition and an inflated condition by introducing an inflating fluid therein. An elongate member extends internally of the inflatable element from its distal end. The internal member is capable of being withdrawn towards the proximal end of the inflatable element to result in the distal end of the element being withdrawn towards the proximal end internally of the element. The invention further provides a locating device comprising a catheter having a catheter tube fitted with one or more inflatable insertion devices at a distal end thereof.

A deflectable multidirectional balloon tipped catheter system for conducting peripheral vascular procedures in a remote entry point such as an opposite extremity or other branch point in the arterial system is provided. The catheter system includes a multidirectional catheter body, which includes a wire lumen and a balloon lumen with a control port for connecting to a balloon control and a balloon inflation port, and a compliant or non-compliant anchor balloon connected near the flexible catheter distal end. A method for treating peripheral vascular disease, administration of pharmaceutical and chemotherapeutic agents to the local vascular system, and therapeutic embolization of vascular territories by using the catheter system is provided.

The invention relates to devices (1) for draining or closing a natural or artificial bladder outlet by means of a balloon body (3) made of preferably micro-scale thin-walled Polyurethane, which has a vesical anchor, is transurethrally sealing and is extended into the urethra or through the urethra. According to the invention, the balloon body is seated on a shaft body (2) supporting the balloon, and the filling of the balloon body is preferably done with air.

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.

Methods and compositions for treatments associated with endovascular grafts, dissections, peripheral aneurysms, and neuro aneurysms are provided that deliver 1,2,3,4,6-pentagalloyl glucose (PGG) or analogues or derivatives thereof and/or LeGoo®. Also provided is a device to deliver 1,2,3,4,6-pentagalloyl glucose (PGG) or analogues or derivatives thereof or LeGoo® to the tissue to be treated.

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 clot capture catheter having an outer inflatable expansile member and an inner inflatable expansile member positioned within the outer inflatable expansile member at a distal end of a shaft of the catheter is presented herein. The inner and outer inflatable expansile members can have differing compliance than each other. Inflation of a higher compliance inner inflatable expansile member can cause a lower compliance outer inflatable expansile member to shorten and provide tension to the distal end of the shaft to case the distal end to open to a funnel shape. Inflation of a lower compliance inner inflatable expansile member can center the distal end of the shaft within a vessel, and inflation of a higher compliance outer inflatable member can provide atraumatic flow arrest to the vessel.

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 balloon catheter including a catheter shaft and an inflatable balloon secured to a distal end region of the catheter shaft. The inflatable balloon has a generally conical shape in a fully inflated configuration having a proximal conical portion that tapers away from the central longitudinal axis in a distal direction from a proximal waist of the balloon and a distal conical portion that tapers toward the central longitudinal axis in a distal direction toward a distal waist of the balloon, with a radially outermost extent of the balloon located between the proximal conical portion and the distal conical portion. The proximal conical portion, the distal conical portion and/or the radially outermost extent of the balloon has an elliptical cross-section taken in a plane perpendicular to the central longitudinal axis of the catheter shaft.

An everting catheter with an expandable inner lumen for the passage of instruments or other devices is described. The catheter can have an inflatable everting balloon. When inflated, the everting balloon can define a channel or passageway, via an inner balloon lumen, into a target site. Instruments can be delivered to the target site through the channel defined by the inflated everting balloon.
