The following quote was obtained by the news editors from the background informa tion supplied by the inventors: “Catheters and other elongated medical devices ( EMDs) may be used for minimally-invasive medical procedures for the diagnosis an d treatment of diseases of various vascular systems, including neurovascular int ervention (NVI) also known as neurointerventional surgery, percutaneous coronary intervention (PCI) and peripheral vascular intervention (PVI). These procedures typically involve navigating a guidewire through the vasculature, and via the g uidewire advancing a catheter to deliver therapy. The catheterization procedure starts by gaining access into the appropriate vessel, such as an artery or vein, with an introducer sheath using standard percutaneous techniques. Through the i ntroducer sheath, a sheath or guide catheter is then advanced over a diagnostic guidewire to a primary location such as an internal carotid artery for NVI, a co ronary ostium for PCI, or a superficial femoral artery for PVI. A guidewire suit able for the vasculature is then navigated through the sheath or guide catheter to a target location in the vasculature. In certain situations, such as in tortu ous anatomy, a support catheter or microcatheter is inserted over the guidewire to assist in navigating the guidewire. The physician or operator may use an imag ing system (e.g., fluoroscope) to obtain a cine with a contrast injection and se lect a fixed frame for use as a roadmap to navigate the guidewire or catheter to the target location, for example, a lesion. Contrast-enhanced images are also o btained while the physician delivers the guidewire or catheter so that the physi cian can verify that the device is moving along the correct path to the target l ocation. While observing the anatomy using fluoroscopy, the physician manipulate s the proximal end of the guidewire or catheter to direct the distal tip into the appropriate vessels toward the lesion or target anatomical location and avoid advancing into side branches.
