Pre-formed delivery catheters

摘要

A delivery catheter includes a pre-formed and resilient heart-wrapping segment. The segment may have a relaxed span that allows the segment to wrap around a left side of a heart from an anterior epicardial surface to a posterior epicardial surface, when the catheter is advanced along the epicardial surface, having been inserted from a sub-xiphoid access site.

1. A delivery catheter including a longitudinally extending lumen for passage of a medical device therethrough, the catheter comprising:
a relatively straight proximal segment including a proximal end and a distal end; and a pre-formed and resilient heart-wrapping segment extending from the distal end of the proximal segment; wherein the heart-wrapping segment includes a first curve extending distally from the proximal segment in a first plane a distance of from between approximately 7.6 cm and approximately 15.2 cm and a second curve extending from the first curve in a second plane a distance of between approximately 4.3 cm and approximately 10.7 cm, wherein the second curve is a compound curve.
