Continuous Transversus Abdominis Plane Block
First Claim
1. A procedure for performing an ultrasound-guided transversus abdominis plane (TAP) procedure, comprising:
- scanning the patient'"'"'s abdomen with an ultrasound probe, and identifying and marking the external oblique, internal oblique, and TAP;
placing an introducer sheath over a fluid delivery needle such that the distal end of the needle extends beyond the distal end of the sheath, the needle having echogenic properties for ultrasound imaging;
ultrasonically guiding the needle and sheath into the TAP;
injecting a local anesthetic or saline/anesthetic combination through the needle and creating a liquid pool in the TAP;
removing the needle from the sheath while maintaining the sheath within the TAP and subsequently advancing a catheter through the sheath and into the pooled liquid in the TAP;
withdrawing the sheath while maintaining the catheter located within the TAP; and
connecting the catheter to a local anesthetic source for providing a defined volume of anesthetic to the catheter site at a controlled delivery rate.

Abstract
A procedure and kit are provided for performing an ultrasound-guided transversus abdominis plane (TAP) procedure. The patient'"'"'s abdomen is scanned with an ultrasound probe to identify and mark the external oblique, internal oblique, and TAP. An introducer sheath is placed over a fluid delivery needle such that the distal end of the needle extends beyond the distal end of the sheath, the needle having echogenic properties for ultrasound imaging. The needle and sheath are ultrasonically guided into the TAP. A local anesthetic or saline/anesthetic combination is injected through the needle to create a liquid pool in the TAP. The needle is removed from the sheath while maintaining the sheath within the TAP and a catheter is subsequently advanced through the sheath and into the pooled liquid in the TAP. The sheath is withdrawn while maintaining the catheter located within the TAP. A catheter is connected to a source of local anesthetic for providing a defined volume of anesthetic to the catheter site at a controlled delivery rate.

8. A medical procedure kit for performing an ultrasound-guided transversus abdominis plane (TAP) procedure, said kit comprising:
a container, said container further comprising; a fluid delivery needle having a length and gauge for penetration into a patient'"'"'s TAP; an extension set having a distal end that mates with said fluid delivery needle; a sheath having a size and length such that said needle slides into said sheath and extends distally beyond a distal end of said sheath; and a TAP catheter having a size and length so as to slide through said sheath, said TAP catheter comprising a reservoir having a defined fill volume and flow rate for delivery of a local anesthetic through said catheter. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
