Patent attributes
An intracardiac ultrasound catheter or other intravascular imaging tool is provided with an adapter to allow the imaging tool to be used both subcutaneously and supracutaneously, and especially at different stages of a single intravascular procedure. The adapter covers a tip of the imaging tool and preferably includes an echogenic window to facilitate gathering of ultrasound images through this window in the adapter. With the adapter in place, the intracardiac ultrasound can be used supracutaneously, such as at a femoral artery/vein location for imaging to improve vascular access, such as with an appropriate percutaneous needle. The adapter is then removed and the same imaging tool can be inserted percutaneously and intravascularly for use, such as in intracardiac imaging accompanying and intracardiac procedure. The intracardiac ultrasound probe is preferably coupled to an electrophysiology mapping system both when used supracutaneously and when used intravascularly.
