Neurovascular intervention device
First Claim
1. An intravascular intervention device comprising:
- a microcatheter configured to fit in a patient'"'"'s neurovasculature, wherein the microcatheter has a diameter equal to or less than 0.027 inches;
an imaging wire received within the microcatheter, the imaging wire comprising an imager configured to image the neurovasculature; and
a treatment device received within the microcatheter and positioned to one side of the imaging wire, the treatment device being adapted to apply treatment to the neurovasculature, wherein the microcatheter is configured to simultaneously receive the imaging wire and the treatment device.

Abstract
The present invention generally relates to medical devices, and more particularly to an improved intravascular intervention device. In one embodiment, an intravascular intervention device includes a microcatheter configured for intravascular delivery, an imaging wire received within the microcatheter, and a treatment device received within the microcatheter, wherein the imaging wire and the treatment device may be simultaneously advanced. The treatment device is configured to perform intravascular intervention. For example, the treatment device may be configured to deliver a stent, an embolic coil and/or a thrombolytic agent. In this embodiment, the intravascular intervention device may image the area of interest while performing the intravascular intervention, thus allowing imaging to take place in real time.
