Textile balloon catheters, textile sleeves useful in balloon catheters, and methods of making balloon catheters are described. An example catheter includes an elongate shaft and a balloon movable between uninflated and inflated configurations, and a textile sleeve secured to the balloon. The textile sleeve has a plurality of warp threads and at least one weft thread extending circumferentially around the balloon. Circumferential loops in the portion of the textile sleeve that is secured to the body of the balloon are larger in diameter than circumferential loops in the portion of the textile sleeve that is secured to one or more of the proximal neck, distal neck, proximal cone and distal cone portions of the balloon.

A medical assembly includes a balloon expandable endoprosthesis comprising a plurality of ringed stent elements flexibly connected to each other via at least one flexible connector, the endoprosthesis being deployable from an undeployed state with an undeployed diameter to a deployed state with a deployed diameter. The medical assembly further includes a catheter assembly comprising a balloon, and a cover along the balloon. The endoprosthesis is coaxially located about the balloon and the cover. One or more portions of the balloon and the cover reach an intermediate diameter between the undeployed diameter and the deployed diameter in which the portions of the balloon and the cover are inflated by increasing an inflation pressure within the balloon and approximately maintained at about the intermediate diameter until the inflation pressure increases by at least 1 atmosphere to overcome a yield strength of the cover.

An occlusion catheter system includes a proximal hub having an inflation connection port and an inflation pathway. An inflation catheter member is connected to the proximal hub and has an inflation lumen. A stiffener member defines a longitudinal axis. The proximal end of the stiffener member is connected to the proximal hub. The stiffener member extends through a portion of the inflation lumen. An occlusion balloon has a proximal balloon end and a distal balloon end. A distal catheter member is positioned substantially on the longitudinal axis and is connected to the distal end of the stiffener member. An atraumatic tip is positioned on a distal end of the distal catheter member. The atraumatic tip has a substantially circular profile in a relaxed configuration. A pressure sensor is connected to the occlusion catheter system distally relative to the occlusion balloon and is connected to a processor by electrical wiring.

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.

A positioning device configured for introduction within a body lumen. Some embodiments include a catheter shaft with a longitudinal axis; an expandable element coupled along a length of the shaft, the expandable element being substantially thin and flexible in an unexpanded state and exerting a gentle outward force in an expanded state; and a deflection mechanism located within the shaft, wherein the deflection mechanism is flexible when in a non-deflected state and wherein, in the deflected state, the deflection curves in a predetermined lateral direction such that the positioning device laterally deflects the body lumen. In some embodiments, the deflection is a lateral curve that moves the body lumen away from a surgical site, such as a cardiac ablation site.

A balloon catheter including an elongated catheter main body portion and a balloon provided on the distal portion of the catheter main body portion. The balloon is inflatable to expand radially outward into an inflated state and deflatable to contract radially inward into a deflated state. The catheter main body portion includes a hollow outer tube and a hollow inner tube disposed within the outer tube. The balloon includes a contact portion that contacts the outer surface of the inner tube and a vane portion protruding from the contact portion radially outward when the balloon is in the deflated state. The contact portion of the balloon includes a connecting portion that connects the balloon to the catheter main body portion.

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 semi-compliant fiber-reinforced medical balloon having a folded wall thickness of from about 0.0010 to about 0.0060 inches and a rated burst pressure of at least 15 atmospheres and exhibiting compliance in the radial direction of from 0.5% expansion per atmosphere to rated burst pressure of the balloon includes a base balloon formed from a semi-elastic polymer about 1.0% expansion per atmosphere when pressurized from a fully inflated diameter to the material having an elongation to break of from about 10% to about 20%, a fiber layer is disposed over the base balloon with fibers having an elongation to break of from about 10% to about 20% and an outer layer formed from a semi-elastic polymer material having an elongation to break of from about 10% to about 20% disposed over the fiber layer.

Described herein are systems and methods from delivering prosthetic devices, such as prosthetic heart valves, through the body and into the heart for implantation therein. The prosthetic devices delivered with the delivery systems disclosed herein are, for example, radially expandable from a radially compressed state mounted on the delivery system to a radially expanded state for implantation using an inflatable balloon of the delivery system. Exemplary delivery routes through the body and into the heart include transfemoral routes, transapical routes, and transaortic routes, among others.

A balloon catheter visualization device includes a handle, an elongate shaft, and an asymmetrical balloon. The elongate shaft includes a distal end, a proximal end, and defines a lumen and a longitudinal axis extending from the proximal end to the distal end. The proximal end is coupled to the handle. The asymmetrical-shaped balloon including a distal portion and a proximal portion. The proximal portion is coupled to the distal end of the elongate shaft. The proximal portion has one or more reinforcement features including a layer of material coupled to the asymmetrical-shaped balloon and forming an outer contour at the proximal portion of the asymmetrical-shaped balloon that is asymmetrical to an outer contour of the distal portion of the asymmetrical-shaped balloon.
