Abstract: The invention relates to a Foley-type catheter constructed to prevent the retention balloon from cuffing, and methods of making the same. In an embodiment, the invention relates to a catheter including an additional sheath layer over the outside surface of the catheter and methods of making and using the same. The catheter includes a central layer that defines a first lumen and a second lumen. The catheter further includes a balloon layer surrounding the central layer and a balloon cavity disposed between the exterior surface of the central layer and the balloon layer. A sheath layer surrounds the balloon layer and extends over the balloon cavity. In an embodiment, the invention relates to a catheter with a retention balloon including ribs and methods of making and using the same. The catheter includes a central layer defining a first lumen and a second lumen and a sheath layer surrounding the central layer. The catheter further includes a balloon cavity. The portion of the sheath layer defining the balloon cavity has a plurality of ribs parallel to the length of the catheter. The ribs include a material that resists stretching more than the material of the sheath layer.

Abstract: A medical device having an elongate support structure and an inflatable balloon including a first-end portion secured to the support structure at a first location, a second-end portion secured to the support structure at a second location distal to the first location, and a middle-body portion. The first-end portion has a wall thickness greater than a wall thickness of the middle-body portion; the balloon defines a sealed interior through which the support structure extends. The balloon being stretch-mounted to the support structure in tension relative to the support structure; the balloon is formed in a diamond-like configuration that transitions to a substantially spherical configuration when the balloon is inflated to a inflation pressure that is at least about ten percent greater than atmospheric pressure, such that when inflated to the inflation pressure and anchored in an anatomical body region, resists movement of the support structure relative to the balloon.

Abstract: Balloon catheter including an outer shaft having a hypotube (220) and a monolithic single-layer distal outer member (230), a balloon (140) in fluid communication with an inflation lumen (200,201,202), and a monolithic inner tubular member (240) having a guidewire lumen (210,211) 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 (231) of the monolithic single-layer distal outer member is coupled to the hypotube. A distal section (222) of the hypotube comprises a skive defined by a first angled cut (420), an axial cut (440), and a second angled cut (460). The balloon has a proximal balloon shaft (145) coupled to a distal end of the monolithic single-layer distal outer member. The monolithic inner tubular member extends distally from a proximal port (280) in the monolithic single-layer distal outer member through the balloon to form a tip (270).

Abstract: A safety catheter includes a flexible, multi-lumen shaft having an outer diameter, a distal tip, a proximal catheter end with a drain end and a proximal inflation end. The multi-lumen shaft defines a drain lumen, a distal hollow balloon portion, at least one inflation lumen, and a drainage port. A hollow stretch valve is coaxially disposed in the inflation or drainage lumen, or both, has a fixed portion within the inflation or drainage lumen, or both, and prevents fluid from passing through the drainage port in a steady state and has a sliding portion slidably disposed within the inflation or drainage lumen, or both, such that, in a stretched state when the proximal catheter end is stretched, the sliding portion slides within the inflation or drainage lumen, or both to permit fluid to pass through the balloon drainage port and/or wall of the catheter.

Abstract: A device and method for dilating a Eustachian tube of a patient is disclosed. The device includes a guide catheter and a balloon dilation catheter. The balloon dilation catheter has an actuator that prevents injury to the middle ear. The balloon dilation catheter is slidably coupled with the guide catheter through the guide catheter lumen and is fully inserted into the guide catheter lumen when the distal side of the actuator is adjacent to the proximal end of the guide catheter. The method involves advancing the guide catheter and balloon dilation catheter through a nasal passage of the patient to dilate a portion of the Eustachian tube.

Abstract: An object of the present invention is to provide a balloon catheter integrated with a guidewire in which a stepped portion is prevented from being formed between a coil portion of the guidewire and a front end portion of the balloon catheter and thus crossability of the balloon catheter is improved. The balloon catheter includes a transition part made of resin that smoothly connects an external shape of an outer coil of a front end coil part and an external shape of a tip portion of a front side inner shaft.
