  • Publication number: 20160129221
    Abstract: A delivery catheter includes a soft, atraumatic distal tip. The distal tip is configured to transition from a folded configuration to an unfolded configuration during delivery of a medical device. A wall thickness of the distal tip may be increased such that the distal tip is biased to remain in the unfolded configuration after delivery. Additionally, the increased wall thickness in a selected region of the distal tip may cause the distal tip to resist and/or prevent collapse of the distal tip during retrieval and/or repositioning of the medical device when the medical device comes into contact with a distal end of the catheter. The distal edge of the distal tip may be rounded so as to prevent the distal tip from damaging tissue during advancement of the catheter to a target location within a patient's body.
