Abstract

Distal tips for use with delivery catheters are disclosed that are configured to maintain complete engagement between the distal tip and a distal opening of a sheath component of the delivery catheter so as to prevent separation therebetween and/or to prevent fish-mouthing of a distal leading edge of the sheath component during in vivo use. Distal tips so configured realize one or more of the objectives of safer tracking of the delivery catheter through the vasculature, safe crossing of the delivery catheter through structural components of the vasculature and heart, such as through native valves, and safe removal of the delivery catheter post deployment.
