Abstract: Catheter devices for treating occlusions in body lumen are described herein. The catheter devices may include a tubular body having a distal end, an distal portion elastically connected to the distal end of the tubular body, an impactor connected to the distal portion and separated by a space from the distal end of the tubular body, a distal shock wave emitter located adjacent to the space and connected to a power source, and an enclosure at least partially surrounding each of the distal end of the tubular body, the elastic distal portion, the impactor, and the distal shock wave emitter. The impactor may be configured to move in response to shock waves generated from the distal shock wave emitter, such that a length of the space in the proximal-distal direction increases by between 0.05 mm and 0.6 mm.

Abstract: A catheter system for treating stenosis in a body lumen includes a first energy source, a second energy source, and a catheter. The catheter includes an elongate member that is navigable through the body lumen, a first acoustic energy emitter connected to the first energy source and configured to emit acoustic energy when energy is received from the first energy source, and a second acoustic energy emitter connected to the second energy source and configured to emit acoustic energy when energy is received from the second energy source.

Abstract: Stent-grafts for treating thoracic aortic aneurysms and abdominal aortic aneurysms include graft portions having inflatable channels and graft extensions. The graft extensions include an undulating wire stent and porous, but substantially fluid impermeable, polytetrafluoroethylene (PTFE) graft materials.

Abstract: A joint and method for producing a joint in an endovascular graft. In one embodiment, a flap of a flexible material portion of an endovascular graft is folded about a portion of an expandable member to form a loop portion. The flap is secured in the loop configuration so that tensile force on the expandable member is transferred into a shear force on the fixed portion of the flap.

Abstract: A device and method for the manufacture of medical devices, specifically, endovascular grafts, or sections thereof. Layers of fusible material are disposed upon a shape forming member and seams formed between the layers in a configuration that can produce inflatable channels in desired portions of the graft. After creation of the seams, the fusible material of the inflatable channels may be fixed while the channels are in an expanded state. A five axis robotic seam forming apparatus may be used to create the seams in the layers of fusible material.

Abstract: Some embodiments relate in part to endovascular prostheses and methods of deploying same. Embodiments may be directed more specifically to inflatable stent grafts and methods of positioning and deploying such devices within the body of a patient. Some embodiments include inflation devices and methods that allow an inflatable portion of an inflatable stent graft to be inflated from a desired location within the inflatable portion.
