Abstract
A fluid dispensing catheter including an elongate body having a proximal portion and a distal portion and defining a passage between the proximal and distal portions, and a plug having a proximal section positioned within the passage in the distal portion of the elongate body to partially occlude the passage, the plug being substantially cylindrical and having a flat parallel to and offset from a longitudinal axis of the plug, the flat defining a gap with the elongate body.
Claims19
A fluid dispensing catheter comprising:
- an elongate body having a proximal portion and a distal portion with a passage defined between the proximal and distal portions;
- and
- a plug having a proximal section positioned within the passage in the distal portion of the elongate body to partially occlude the passage, the plug being substantially cylindrical and having a flat parallel to and offset from a longitudinal axis of the plug, the flat defining a gap with the elongate body.
A method of delivering fluid to target locations within a patient, the method comprising:
- positioning a distal portion of a fluid dispensing catheter adjacent a target location within a patient, the catheter having an inner member defining a passage;
- and
- manipulating a proximal portion of the catheter disposed external to the patient to expel fluid from within the distal portion of catheter, the distal portion including a plug partially occluding the passage of the catheter, the plug having a flat defining a gap with the inner member such that fluid is expelled from the distal portion in a controlled manner.
