Low profile fluid delivery and sealing system for a catheter

摘要

A plug system for a low profile hollow catheter or other guidewire or balloon catheter, which catheter has a distal portion and a proximal portion and at least one lumen in fluid communication therebetween. The catheter further has an outer diameter in the range of about 0.01'' to 0.04'' and an inner diameter in the range of about 0.007'' to 0.035''. The plug system comprises an elastomeric plug for engaging and sealing a proximal open end of the catheter in such a way that the maximum outer diameter of the plug does not exceed the outer diameter of the catheter. A low profile fluid delivery and sealing system for a catheter with a lumen comprises a pierceable and self-resealable member sealably coupled to the lumen at a proximal portion of the catheter forming an assembly. The transverse cross sectional area of the assembly as viewed along a longitudinal axis of the catheter does not exceed 150% of the original transverse cross sectional area of the catheter.
