Dilatation balloons and catheters including same are provided. The balloons are fabricated of a biaxially orientable material such as a nylon or a polyamide material, and they have an inflated, non-distened working profile as well as a stretched inflated profile which is achieved by applying pressure through a dilatation catheter or the like that is in excess of that needed to achieve the inflated, non-distended profile and which is adequate to effect dilatation or the like up to a maximum pre-b...

A pre-compressed angioplasty balloon catheter and method of manufacture wherein the balloon portion of the catheter is wrapped for storage and for minimizing its outside diameter for purpose of insertion into the body.

Apparatus and methods for forming dilatation balloons and catheters including same are provided. The balloons are fabricated of a biaxially orientable material such as a nylon or a polyamide material, and they have an inflated, non-distended working profile as well as a stretched inflated profile which is achieved by applying pressure through a dilatation catheter or the like that is in excess of that needed to achieve the inflated, non-distended profile and which is adequate to effect dilatatio...

An endoprosthesis for angioplasty of a vessel injured by an aneurysm wherein the vessel intersects another vessel and has an intersection point which forms right angles between axial lines extending through the vessels and wherein the vessel has a neck portion extending from the another vessel including an expandable frame covered by an impermeable material and having a beveled end adapted to engage the neck portion, wherein an angle of the beveled end is determined such that a front plane of th...

The dilation balloon of the subject invention preferably comprises a balloon portion mounted about a shaft that, when inflated, produces a configuration comprising a tapered distal end and a proximal end or butt that is substantially flat (preferably truncated) and is adapted to generally conform with the outer contours of an endoscope through which it is introduced when the balloon is pulled back against the endoscope face. The close engagement of the subject balloon catheter and endoscope, whe...

The invention is a chemical-mechanical polishing wafer carrier that is able to apply a plurality of different pressures, with minimal discontinuities at the interfaces between different pressures, through a diaphragm to a back surface of a wafer. A plurality of concentric balloons, that may be individually pressurized, is used to support and press on the back surface of the diaphragm. The walls of the balloons are preferably thin and elastic and preferably do not attach to the diaphragm. This he...

A mobile blower or fan is used to inflate the envelope portion of a hot air balloon. The fan includes a propeller which is driven by a gasoline/fuel engine and the engine is mounted on a wheeled base and is covered by an encompassing cage. By means of wheels attached to the base, it is possible to move the fan or blower on all types of terrain as needed.

A versatile multiple spout balloon network is provided with thin walled, resilient, single or multiple spout balloons which may be interconnected to other balloons or a pole using plugs. Plugs provide for resilient and airtight engagement of balloons at their spouts. Plugs may include an air channel for passage of air between balloons and the network. The network may include one or more poles, each pole having several branches. Balloons may make an airtight and resilient engagement with the pole...
