An occlusion assembly and its uses in a REBOA procedure is disclosed. The occlusion assembly includes a single elongate shaft having an inflatable balloon, a proximal neck portion, a distal neck portion. The shaft defines a single lumen through which a wire is positioned for support of the shaft and through which an inflation fluid is also passed to inflate the balloon.

Providing a method for producing a balloon catheter, that is capable of uniformly heating and cooling the entire mold and less likely to cause temperature unevenness. A method for producing a balloon catheter which comprises a shaft extending in a longitudinal direction and a medical resin balloon provided at a distal end portion of the shaft, comprising the steps of inserting a resin tubular body (10) into a mold (20), and placing the mold (20) inside a thermal jacket (30) wherein a porous metal body (50) is disposed outside the mold (20) and inside the thermal jacket (30).

A medical instrument includes a shaft, a distal-end assembly and a puller-wire. The shaft is configured for insertion into a body of a patient. The distal-end assembly, which is coupled to the shaft, includes a telescopic assembly, configured to elongate so as to collapse the distal-end assembly, and to compress so as to expand the distal-end assembly. The distal-end assembly further includes an elastic element, coupled to self-elongate and thus elongate the telescopic assembly. The distal-end assembly also includes an inflatable balloon, which is coupled to the telescopic assembly and is configured to collapse by the telescopic assembly elongating, and to expand by the telescopic assembly compressing. The puller-wire runs through the shaft and is connected to a distal end of the telescopic assembly, and is configured, when pulled, to compress the telescopic assembly.

A balloon catheter is disclosed which allows easier fusion-bonding between an inner tube shaft and an outer tube shaft and in which the inner tube shaft can be prevented from being warped when the inner tube shaft passes through a stenosed site, and a method of manufacturing such a balloon catheter. The balloon catheter includes an inner tube shaft having a first layer and a second layer located on an inner surface side of the first layer. The outer tube shaft is fusion-bonded to the first layer and recessed toward the inner tube shaft side. The first layer is formed of a material having higher optical absorption property than the outer tube shaft and the second layer. The second layer is formed of a material having a melting point higher than that of the first layer.

An inflatable structure for use in biological lumens and methods of making and using the same are disclosed. The structure can have an inflatable balloon encircled by a shell. The shell can have proximal and distal tapered necks, longitudinally-oriented flutes, and apertures at the proximal and distal ends of the shell. The apertures can be recessed in the flutes in the necks. The shell can also have fiber reinforced walls.

Balloon catheter includes an outer shaft having a hypotube and a monolithic single-layer distal outer member, a balloon in fluid communication with an inflation lumen, and a monolithic inner tubular member having a guidewire lumen defined therethrough. The outer shaft has the inflation lumen defined therethrough. The monolithic single-layer distal outer member is necked to a reduced diameter along an entire length thereof. A proximal end of the monolithic single-layer distal outer member is coupled to the hypotube. A distal section of the hypotube comprises a skive defined by a first angled cut, an axial cut, and a second angled cut. The balloon has a proximal balloon shaft coupled to a distal end of the monolithic single-layer distal outer member. The monolithic inner tubular member extends distally from a proximal port in the monolithic single-layer distal outer member through the balloon to form a tip.

A catheter comprising: a shaft (1) having a proximal end (2) and a distal end (3), the distal end terminating in a tip (4); a drainage opening (7) located at the distal end of the shaft, the drainage opening communicating with a drainage lumen (8) of the shaft; a balloon located at the distal end of the shaft, the balloon comprising a first region secured to the shaft, a second region secured to the shaft and an elastic-walled conduit extending between the first region and the second region, the elastic conduit extending over the tip.

Methods for making medical devices and portions of medical devices (e.g., intravascular catheters, catheter shafts, and tubular guiding members) are provided. Example methods may include providing a first ribbon comprising one or more thermoplastic materials and a piece of shrink tubing defining a shrink tube lumen and forming a first assembly by positioning the first ribbon inside the shrink tube lumen and urging the first ribbon to assume a tubular shape in which the first ribbon defines a ribbon lumen. A second assembly may be formed by loading an inner tubular member over a mandrel and forming or placing a support structure over an outer surface of the inner tubular member. A third assembly may be formed by inserting the second assembly into the ribbon lumen defined by the first ribbon of the first assembly. The third assembly may be heated to a process temperature.

Provided are a package of a mounting jig mounted balloon and a balloon mounting method capable of reducing the burden of an operation of mounting a balloon in an insertion part of an endoscope. A balloon includes a first sleeve part, a second sleeve part, and a balloon main body. A balloon mounting jig is formed to be folded flat in a hollow cylindrical shape, and has a main body having a first opening part and a second opening part, and a pair of guide pieces that is provided on the second opening part and face each other. A package of a mounting jig mounted balloon is configured so that the balloon mounting jig and the balloon are contained in the container, in which in the container, the balloon is disposed so that the second sleeve part is disposed inside the folded balloon main body and the pair of guide pieces is disposed inside the first sleeve part and the second sleeve part.

The geometry of a toroidal balloon requires that a traditional cylindrical balloon to be rotated internally into itself and the ends of the cylinder be placed in close proximity for maximal balloon rotation and to allow an entrance port for inflation of the balloon and/or attachment to an associated medical device. Described within are various techniques for the creation of such toroidal balloons.
