Described herein is a shock wave device for the treatment of vascular occlusions. The shock wave device includes an outer covering and an inner member inner connected at a distal end of the device. First and second conductive wires extend along the length of the device within the volume between the outer covering and the inner member. A conductive emitter band circumscribes the ends of the first and second wires to form a first spark gap between the end of the first wire and the emitter band and a second spark gap between the end of the second wire and the emitter band. When the volume is filled with conductive fluid and a high voltage pulse is applied across the first and second wires, first and second shock waves can be initiated from the first and second spark gaps.

Embodiments can provide an expandable nasogastric intubation assembly, comprising a tube subassembly and an expander subassembly, comprising an inflatable balloon comprising a proximal expander component section and a distal expander component section wherein the proximal expander component section is located between the proximal end of the intubation assembly and the distal expander component section; wherein the distal expander component section is located between the distal end of the intubation assembly and the proximal expander component section; wherein the inflatable balloon is coupled to the tube subassembly, the proximal expander component section is configured to be inflated from an injection of fluid into at least one first opening located in the second passageway, and the distal expander component section is configured to be inflated by the injection of fluid into at least one second opening located in the second passageway.

A device having a sheath, a medical device, a stylet, a handle and a plunger device. The handle includes portions connected proximal ends of the sheath, the medical device and the stylet and a chamber portion connected to the actuator. The chamber portion includes a volume of space configured to volumetrically connect to at a lumen of the medical device, the sheath or the stylet and a plunger device configured to be slidably received within the chamber portion. The plunger device is able to pneumatically isolate a proximal portion of the volume of space from a distal portion of the volume of space. Proximal movement of the stylet and the plunger device cause a suction effect (i.e., reduced pressure) at the distal end of the sheath, the medical device and/or the stylet.

The invention provides an improved indwelling urinary catheter of the inflatable type having a unique, low profile device by which to retain the catheter within the bladder, so that urine can be removed therefrom while avoiding obstruction to the descending fetal vertex during the process of labor and delivery, Thus, making it better suited for obstetrical applications. The retaining device consumes less obstructing volume in the bladder than that which would ordinarily be consumed by a conventional Foley-style balloon, whereby both the frequency and severity of fetal vertex obstruction and its resulting increased time of labor, operative delivery and injury to maternal urologic tissue can be reduced. The obstetrical Foley retains the tradition Foley-style balloon distal to the improved low-profile laboring balloon for insufflation in the event a surgical delivery by cesarean section is indicated. The traditional balloon with its larger volume allows easy identification of the bladder during surgical delivery. This unique design allows the added advantage of multiple options and uses in a single Foley catheter without the need of changing catheters.

Expandable intubation assemblies and methods for using and making the same are provided.

A device is provided for delivery of a therapeutic agent to the anal and perianal regions. The device includes a deployable internal anchor adapted to comfortably anchor the device in the anal canal, a shaft adapted to store and release the agent to the anal canal, and an external bumper adapted to store and release the agent to the perianal tissue and externally anchor the device.

A medical balloon comprises a first end, a second end spaced apart from the first, and a generally cylindrical balloon wall extending therebetween to define an inflation chamber. The balloon wall is adapted for inflation from a first folded configuration having a first plurality of pleats to an expanded, unpleated configuration, and deflation therefrom to a second folded configuration having a second plurality of pleats. The balloon wall includes a first layer formed of a polymer and having a substantially constant radial thickness. A second layer is firmly attached to the first layer and has a plurality of first regions of greater radial thickness interleaved with a plurality of second regions of reduced radial thickness. During deflation from the expanded, unpleated configuration to the second folded configuration, the balloon wall folds along the regions of reduced radial thickness of the second layer to form the second plurality of pleats.

A compliance restoration device includes a compliance balloon lumen, a chamber support structure disposed in the compliance balloon lumen and configured to expand to support an expanded volume of the compliance balloon lumen, and a spring assembly configured to cause the chamber support structure to expand by applying a force on a first end of the chamber support structure.

An inflatable bone tamp includes an outer shaft defining a passageway. An inner shaft is positioned within the passageway. The inner shaft defines a lumen. A balloon has a first end coupled to the outer shaft and a second end coupled to the inner shaft such that material can flow through the lumen and into the balloon and exit the balloon through a channel between the inner and outer shafts. A valve is positioned within the channel. The valve is configured to move from a closed orientation in which the valve blocks the channel and an open orientation in which the does not block the channel. Kits, systems and methods are disclosed.

The balloon includes a pouch formed of a sealed wall delimiting an internal space, and a valve for filling the internal space with a fluid, capable of being occluded after filling the internal space. The pouch delimits a fluid-draining orifice opening into the internal space. The balloon further includes an occluding ball that occludes the draining orifice. The occluding ball can be spherical or polyhedral, and be capable of releasing the draining orifice under the effect of a magnetic field, so as to enable the at least partial drainage of the fluid contained in the internal space. The occluding ball is movable along at least two distinct axes in relation to the pouch.
