Abstract
A system () and apparatus comprising a multisensor guidewire () for use in interventional cardiology, e.g., Transcatheter Valve Therapies (TVT), comprises a plurality of optical sensors () for direct measurement of cardiovascular parameters, e.g. transvalvular blood pressure gradients and flow. A conventional outer coil wire () contains a shaped core wire () having a cross-section defining a channel surface (), e.g. grooves (), extending along its length, to position optical fibers () and optical sensors () in a channel (). Advantageously, the core wire has a diameter that provides sufficient stiffness to the guidewire for use as a support guidewire for TVT, e.g. Transcatheter Aortic Valve Implantation (TAVI), while accommodating multiple sensors and fibers within a guidewire of outside diameter ≤0.89 mm. An optical connector () couples the guidewire to a control system (). Optionally, the guidewire includes a contact force sensor (), a pre-formed tip (--) and a separable micro-connector ().
