1. An injection adaptor for a catheter;
- the catheter having a proximal end and a distal end;
the distal end of the catheter being configured for insertion into bodily tissue;
the proximal end being configured to remain outside of the bodily tissue;
the catheter including a catheter lumen;
the catheter lumen having a proximal opening at the proximal end of the catheter, and a distal opening at the distal end of the catheter;
the adaptor including an adaptor lumen, a first port, and a second port;
the adaptor lumen connecting the first port and the second port;
the first port being configured to create a first fluid-tight seal with the proximal opening of the catheter lumen, and thereby connect the adaptor lumen to the catheter lumen;
the second port being configured to create a releasable and resealable second fluid-tight seal with a stylet inserted through the second port of the adaptor;
the stylet including an elongated shaft configured to be inserted through the second port of the adaptor and into the catheter lumen when the first port of the adaptor creates the first fluid-tight seal with the proximal opening of the catheter lumen, wherein the stylet is an electrode configured to permit electrical signals to be conducted to an active tip of the catheter and thereby delivered to tissue in contact with the active tip.
