An automated system and method are disclosed for producing an inflatable product having a first sheet, a second sheet, and a plurality of tensioning structures between the first and second sheets. The system includes an upstream tensioning structure production subsystem that produces the tensioning structures and a downstream preassembly production subsystem that couples the tensioning structures to the first and second sheets. The subsystems may operate simultaneously to produce the inflatable product in an automated, efficient, and repeatable manner.

Bellows, for example, a roll bellows and a folding bellows, can be produced that can be used at higher temperatures such as those prevailing in modern articulated constructions, using a mixture comprising at least one thermoplastic elastomer selected from the group of copolysters with a hard segment and a soft segment, wherein in a first step the at least one thermoplastic elastomer is mixed with approximately 0.8 wt. % to approximately 5 wt. % triallyl isocyanurate, based on the total amount of the mixture; in a second step the bellows is produced; and in a third step, the bellows is exposed to an ionizing irradiation in a range from approximately 140 kGy to approximately 350 kGy.

Various embodiments disclosed relate to drug-coated balloon catheters for treating strictures in body lumens and methods of using the same. A drug-coated balloon catheter for delivering a therapeutic agent to a target site of a body lumen stricture includes an elongated balloon having a main diameter. The balloon catheter includes a coating layer overlying an exterior surface of the balloon. The coating layer includes one or more water-soluble additives and an initial drug load of a therapeutic agent.

An inflatable boat processing method, an inflatable boat and a processing device thereof, wherein the processing method comprising: cutting material into boat-side material pieces and a boat bottom material piece following an inflatable boat sample; connecting the adjacent edges of the boat-side material pieces in an overlapped mode, thereby obtaining a boat-side body; connecting the boat-side body with the boat bottom, wherein a first connecting end of the boat-side body is connected with the boat bottom material piece in an overlapped mode by means of pressing and ultrasonic bonding; sealing the boat-side body, wherein the edge of the first connecting end is connected with the edge of the second connecting end of the boat-side body in an overlapped mode; obtaining an inflatable boat. A heating-and-pressing device and an ultrasonic soldering device are adopted to perform hot-melting and pressing, thereby achieving the connection of two material pieces using ultrasonic bonding.

A system and method for forming a seam between at least first and possibly second pieces of material used to form an inflatable product utilizes at least a first and potentially a second seam forming members that are attached to an inside wall of a piece of product material that comprises the inflatable product proximate each end. The inflatable product is comprised of one or more pieces of product material and one or more seam forming members located at any location where a seam is necessary. A first portion of the seam forming member attaches to a first edge of a first piece of product material and a second portion of the seam forming member attaches proximate a second edge of the first piece of product material. The seal forming can be accomplished by radio frequency, ultrasonic, heat or other types of welding, and adhesive or chemical based bonding.

A sports ball comprising a transparent outer wall surrounding a hollow cavity and defining a geometric center, and a central core object suspended at the geometric center of the hollow cavity. The ball may have the shape of a sphere having a center point, with the central core object suspended at the center point of the sphere. In other cases, the ball may be oblong or ellipsoid, with the central core object suspended at the center points of the respective major and minor axes of the ellipsoid. The transparent outer wall of the ball may be elastically deformable, and may be comprised of a transparent inflatable bladder contiguous with an inner surface of a transparent outer skin. The transparent outer skin may be comprised of a plurality of outer facets joined together, such as by sewing.
