Abstract
The invention generally relates to an auxiliary guidewire for an intravascular procedure. The invention provides an auxiliary guidewire that slips over a primary guidewire and can provide a very fine extension beyond the end of the primary guidewire. The primary guidewire can be taken to its limit within the fine vasculature, and the auxiliary guidewire can then extend further into the fine vasculature. The primary guidewire can be taken to a bifurcation. The primary guidewire and the auxiliary guidewire can be sent down separate branches of the bifurcation. A physician can select which of the primary guidewire and the auxiliary guidewire are within the branch that needs to be treated by, for example, consulting an angiography display.
