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.
Claims17
A fluid dispensing catheter comprising:
- an elongate body including:
- an inner member having a proximal portion and a distal portion with a first passage defined between the proximal and distal portions;
- and
- an outer member extending distally past the inner member and defining a second passage, the inner member disposed within the second passage;
- and
- a plug having a proximal section and a distal section, the proximal section positioned within the first passage in the distal portion of the inner member to partially occlude the first 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, the distal section of the plug extending distally from the proximal section and positioned outside of the first passage and within the second passage.
3 more elements
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 first 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 first 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, a distal section of the plug positioned outside of the first passage of the catheter, the catheter having an outer member defining a second passage, the inner member and the distal section of the plug disposed within the second passage.
