A balloon catheter includes a one-piece extrusion having inner and outer tubular walls, where the inner tubular wall defines a wire guide lumen, and a clearance extending between the inner and outer tubular walls forms an inflation lumen. A balloon is attached to the outer tubular wall and to the inner tubular wall, such that the inflation lumen is in fluid communication with the balloon and the wire guide lumen extends through the balloon. A method of making the balloon catheter is also disclosed.

A clot capture catheter comprises an elongate tubular shaft having a proximal end, a distal end and an inflatable expansile member at the distal end. The expansile member is inflatable from a collapsed delivery configuration to an expanded configuration. In the expanded configuration, the expansile member extends to define a funnel shape having an enlarged distal clot entry mouth at the distal-most end of the catheter. In the expanded configuration, the expansile member may extend distally beyond the distalmost tip of the shaft. The expansile member may be integral with the distal tip of the catheter shaft.

Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a catheter. The catheter may include a catheter shaft and a balloon. The balloon may comprise a cone portion, a waist portion, and a body portion. A fiber braid may be disposed along the balloon. An inner surface of the waist portion may be thermally bonded to an outer surface of the catheter shaft and an inner surface of the fiber braid may be adhesively bonded to an outer surface of the waist portion.

A method for producing a balloon catheter including preparing a balloon producing device (1), the device including a mold (10) into which a parison (50) is inserted, and a fixing member (30) for fixing the parison (50) outside the mold (10), the mold (10) provided with a rotation preventing portion (20) abutting the parison (50) so as to prevent rotation of the parison (50), disposing a part of the parison (50) in the mold (10), fixing a portion outside the mold (10) of the parison (50) with the fixing member (30), expanding the parison (50), removing the parison (50) from the mold (10), and cutting the parison (50).

A balloon catheter is described having a reinforced, co-axial, duel lumen design. In some embodiments, the balloon catheter includes a purging mechanism designed to purge air from the balloon.

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.

An endoscopy system including a balloon-equipped endoscope including a balloon which is configured for slidable frictional engagement with an interior wall of a body passageway and axial stretching of the interior wall when inflated to a slidable frictional engagement pressure and displaced axially along the body passageway and a balloon inflation subsystem operative to selectably inflate the balloon to the slidable frictional engagement pressure.

A catheter (1) includes an elongated member (2) having a proximal end (4) and a distal end (3). An inflatable balloon (5) is arranged on the elongated member in an area of the distal end thereof, the balloon extending from a distal position (6) to a proximal position (7). The elongated member includes an inner lumen (8) extending from the distal end to an end position (9) which is proximal to the balloon. The inner lumen is open at the distal end. The catheter further includes a duct (12) connected to the proximal end and to the balloon at the proximal position. The duct defines a separate lumen to convey a fluid to and from the balloon.

A system includes a first tubular member comprising a first polymer and a second tubular member comprising a second polymer. The first tubular member defines a lumen configured to receive at least a portion of the second tubular member therein to define a joint region. The system further includes a compression sleeve configured to receive at least a portion of the first tubular member at the joint region and an energy source comprising a fiber laser configured to deliver energy to the joint region to thermally weld the first tubular member to the second tubular member. In some examples, the energy includes a wavelength of radiation transmittable through the compression sleeve and the first tubular member, and absorbable by the first tubular member and the second tubular member.

An inflatable cuff for an endotracheal tube system has a sealing component that is one or a combination of (a) a proximal one-directional valve configured to deflect with underpressure during the intubation procedure and contact the tracheal wall of a patient to provide sealing, (b) a distal one-directional valve configured to deflect with overpressure during the intubation procedure and contact the tracheal wall to provide sealing; and (c) a cloud shape of the inflatable portion. The cloud shape is defined by at least one sealing section of the inflatable portion having a primary maximum inflated diameter and at least one non-sealing section of the inflatable portion having a maximum inflated diameter less than the primary maximum inflated diameter. The inflatable cuff may be inflatable by a ventilation tube. The system may include a cuff controller that senses airflow parameters and provides regulated flows of air during an intubation procedure.
