Abstract
The catheter and introducer needle assembly of this invention includes a catheter adapter at its proximal end having a hollow septum disposed therein. The septum preferably is hollow to minimize drag as the introducer needle is removed therefrom. If desired a gel or lubricious material may be disposed in the cavity.
Claims23
A catheter and introducer needle assembly, comprising:
- a catheter having a proximal end and a distal end;
- a catheter adapter in fluid communication with the catheter and having a proximal end and a distal end connected to the proximal end of the catheter, the catheter adapter including a side port in fluid communication with the catheter adapter;
- an introducer needle having a proximal end and a distal end disposed inside the catheter wherein the introducer needle defines a notch therein adjacent to the distal end and defining a notch distance between a proximal end of the notch and the distal end of the introducer needle;
- a needle hub having a proximal end and a distal end connected to the proximal end of needle;
- and
- an elastomeric septum defining a cavity therein disposed in the catheter adapter and located proximal of the side port wherein the septum has a length greater than the notch distance.

A catheter and introducer needle assembly, comprising:
- a catheter having a proximal end and a distal end;
- a catheter adapter in fluid communication with the catheter and having a proximal end and a distal end connected to the proximal end of the catheter, the catheter adapter including a side port in fluid communication with the catheter adapter;
- a septum holder disposed in the catheter adapter and located proximal of the side port;
- a septum disposed in the septum holder and including a septum proximal portion and a septum distal portion and defining a cavity between the proximal portion and the distal portion;
- an introducer needle having a proximal end and a distal end disposed inside the catheter wherein the introducer needle defines a notch therein adjacent to the distal end and defining a notch distance between a proximal end of the notch and the distal end of the introducer needle wherein the length of the septum is at least as long as the notch distance;
- and
- a needle hub having a proximal end and a distal end connected to the proximal end of needle.
4 more elements
A septum assembly, comprising:
- a septum holder;
- and
- a septum disposed in the septum holder and including a septum proximal portion and a septum distal portion and defining a cavity between the septum proximal portion and the septum distal portion wherein the septum proximal portion is a separate piece than the septum distal portion.
