Benefits of technology

[0036]The support wire is a dual element support wire having a core and an annular shell that slides on the core. The distal end of the core is attached to the distal end of the annular braided element and the distal end of the shell is attached to the proximal end of the annular braided element. Thus movement of the core and shell relative to one another moves the braided element from a radially retracted position which is useful for insertion into the body to a radially expanded position which expands it to the sidewall of the tubular channel or against other tissue or matter within the body. When the annular braided element is in its radially co...

Problems solved by technology

Guide wire management in the operating room is problematic, and threading the needle of the arteries or other vessels including, but not limited to veins, intestines, fallopian tubes, etc. to reach the area to be treated is difficult.

Further, once the guide is in the desired location, it is often difficult to make certain that the it remains in that location.

Even further, once the guide wire, catheter, endoscope or other device is in the desired location and another device is placed over, through or along side it, the initially placed device has a tendency to move due to the forces exerted on it when other devices are using it as a guide.

A device, even though it performs a function in some improved manner, will not be widely used if it is considerably more costly than the alternatives available.

It will also tend to keep cost low.

Often this trauma is not realized immediately after surgery.

Extreme simplicity and a very simple procedure might over compromise safety.

Occlusive vascular disease is ...
