Catheter system for the delivery of a low volume liquid bolus |
摘要 |
A catheter system includes a catheter having a proximal end, a distal end, and a lumen extending therein. An elongate mender slidably disposed in the lumen has a distal end located proximate the distal end of the catheter. An administering tip is disposed at the distal end of the catheter and is configured to express a bolus of liquid in response to positive pressure in a distal portion of the lumen created by movement of the elongate member distally in the lumen. The present invention also includes a method of administering a liquid to a treatment site. The distal end of the catheter is transluminally positioned proximate the treatment site. The catheter is charged by placing a bolus of the liquid in a distal end of the lumen between a distal tip of the catheter and a distal end of the elongate member. The elongate member is then moved distally within the lumen to express the bolus from the distal end of the catheter.
