Abstract
A medical device includes a first tube having a first lumen and a second tube having a second lumen, wherein the first tube is coupled to the second tube by a coating agent along at least one coupling portion in a longitudinal direction of the medical device.
Claims12
A medical device comprising:
- a first tube having a first lumen;
- and
- a second tube having a second lumen, wherein the first tube is coupled to the second tube by a coating layer along at least one coupling portion in a longitudinal direction of the medical device.
A catheter, comprising:
- an elongate catheter body having a proximal end and a distal end, the catheter body including:
- a sensor tube defining a sensor lumen configured to receive an ultrasonic imaging sensor;
- and
- a guidewire tube defining a guidewire lumen configured to slidably receive a guidewire, the guidewire tube being positioned adjacent to the sensor tube, wherein
- the sensor tube and the guidewire tube are coupled to one another along a discrete coupling portion by a coating layer, the coating layer forming a thin film that adheres to outer surfaces of the sensor tube and the guidewire tube while providing a recess portion between the sensor tube and the guidewire tube.
