From the background information supplied by the inventors, news correspondents obtained the followingquote: “Catheters and other elongated medical devices (EMDs) may be used for minimally-invasivemedical procedures for the diagnosis and treatment of diseases of various vascular systems, includingneurovascular intervention (NVI) also known as neurointerventional surgery, percutaneous coronary intervention(PCI) and peripheral vascular intervention (PVI). These procedures typically involve navigating aguidewire through the vasculature, and via the guidewire advancing a catheter to deliver therapy. Thecatheterization procedure starts by gaining access into the appropriate vessel, such as an artery or vein, withan introducer sheath using standard percutaneous techniques. Through the introducer sheath, a sheathor guide catheter is then advanced over a diagnostic guidewire to a primary location such as an internalcarotid artery for NVI, a coronary ostium for PCI, or a superficial femoral artery for PVI. A guidewiresuitable for the vasculature is then navigated through the sheath or guide catheter to a target location inthe vasculature. In certain situations, such as in tortuous anatomy, a support catheter or microcatheteris inserted over the guidewire to assist in navigating the guidewire. The physician or operator may usean imaging system (e.g., fluoroscope) to obtain a cine with a contrast injection and select a fixed framefor use as a roadmap to navigate the guidewire or catheter to the target location, for example, a lesion.Contrast-enhanced images are also obtained while the physician delivers the guidewire or catheter so thatthe physician can verify that the device is moving along the correct path to the target location. Whileobserving the anatomy using fluoroscopy, the physician manipulates the proximal end of the guidewire orcatheter to direct the distal tip into the appropriate vessels toward the lesion or target anatomical locationand avoid advancing into side branches.
