TRANSCATHETER PUNCTURE NEEDLE SYSTEM

Abstract:

A puncture needle can comprise a puncture tip configured to pierce tissue, and a distal portion comprising an anchor portion and a curved puncture portion. The curved puncture portion can comprise a first end associated with the puncture tip and a second end coupled to the anchor portion, where the anchor portion comprises a portion distal of the curved puncture portion. A puncture needle system can comprise the puncture needle and a delivery catheter comprising a lumen, the puncture needle extending through the lumen. The delivery catheter can have a side outlet opening on a distal portion of the delivery catheter configured to allow extension therethrough of at least a portion of the curved puncture portion, where the anchor portion extends through a portion of the lumen distal of the side outlet opening.
