- the braid may, however, be a radiopaque material such as the metals and alloys and polymers discussed above.
- the braid may be joined by welding, melting, or by adhesion to the underlying coil 121.
- the fluid ⁇ like properties of the coil within a carrier fluid enable it to conform to the complex geometry of certain fragile, abnormal blood vessels, and in so doing, minimize the risk of causing trauma to or perforation of those
- the length of the coil is fairly short to allow "microcontrol" of the occlusion of the small cardiac arteries and resultant control of the arrhythmia.
- the Gugiiemi et al. patent is incorporated herein in its entirety by reference.
