Embodiment Construction

[0173] figure 1 One embodiment of a method 10 for generating and propagating mechanical impulses is shown. In one embodiment, the method may be adapted to treat vascular occlusions, ie through blockages present in blood vessels such as veins or arteries, or in any other conducting body present in the human body. Method 10 may have application in fields other than the medical field. For example, the method can be used to traverse occlusions / obstacles present in a conductor used to propagate water or any other fluid.

[0174] At step 12, at least one mechanical pulse is generated. Each mechanical pulse has high amplitude and short duration.

[0175] In one embodiment, the outputs of several sources covering adjacent frequency bands are combined to generate mechanical pulses. In one embodiment, the outputs of at least two broadband sources, ie the mechanical pulses generated by the at least two broadband sources, are combined. In another embodiment, the outputs of at least o...

Abstract

There is described a method for generating a mechanical wave, comprising: generating a high amplitude mechanical pulse; coupling the mechanical pulse in a proximal end of a transmission member; propagating the mechanical pulse into the transmission member from the proximal end and a distal end thereof; and transmitting the mechanical pulse at the distal end.

Description

technical field [0001] The present invention relates to the field of methods and systems for generating mechanical impulses. Background technique [0002] Cardiovascular disease remains the leading cause of death worldwide. Atherosclerosis consists of the buildup of plaque along the inner walls of arteries. Chronic total occlusion (CTO) means a blood vessel is completely blocked. These occlusions are difficult to recanalize using conventional percutaneous transluminal angioplasty (PTA) techniques and devices. Procedural success was defined as the ability to pass a standard PTA device across the CTO. PTA procedural defects and complications are generally higher for CTO. The presence of calcified and fibrotic tissue as well as vessel size and tortuosity in CTO lesions may be the cause of potential complications. Therefore, invasive bypass surgery is used to treat a large number of CTOs. However, there are benefits to surgically crossing the CTO using PTA. In addition, s...
