Abstract:
1. A catheter based medical device for a percutaneous surgical procedure that provides forward-looking visualization and is configured to deliver a medical device, comprising: a catheter having a distal end, a proximal end, and a sidewall defining an interior lumen; a carriage supported by the distal end of the catheter; an ultrasonic transducer supported by the carriage such that the transducer is free to move in a sweep path; a conduit having a proximal end, a distal end, and a sidewall defining a second interior lumen, the proximal end of the conduit being disposed within the interior lumen of the catheter such that a length of the conduit extends longitudinally within the interior lumen, wherein the conduit passes through the sidewall of the catheter at a location spaced from the distal end of the catheter such that a first portion of the conduit extends longitudinally along an exterior of the sidewall of the catheter, with the distal end of the conduit being disposed external to the sidewall of the catheter, wherein a longitudinal axis of the first portion of the conduit is parallel to a longitudinal axis of the catheter; and wherein the conduit is configured for receiving a medical device through the second interior lumen of the conduit and wherein the ultrasonic transducer permits visualization of the medical device distally of the transducer.
