DELIVERY SYSTEM FOR IMPLANTABLE MEDICAL DEVICE

摘要

A delivery system includes an inflatable delivery balloon formed with a plurality of constraining elements which create constrained regions in a body portion of the balloon, interposed between unconstrained regions. The constrained regions create recesses for receiving a medical device or part of a medical device. The constraining elements are preferably formed by woven or braided material, advantageously embedded within the wall of the inflatable balloon. The constraining elements provide a structure that will not flatten upon inflation of the balloon and also a structure which can readily be folded or wrapped for endoluminal delivery purposes, and which retains flexibility of the delivery device.

主权项

1. An endoluminal delivery device including:
a catheter unit; a delivery balloon mounted on the catheter unit, the balloon including a body portion and first and second end portions coupled to the catheter unit, the body portion providing a medical device support surface; the delivery balloon being inflatable so as to cause the body portion to expand to an inflated, first diameter; and at least one circumferential constraining element disposed around at least a part of the body portion, the at least one circumferential constraining element acting to constrain inflation of at least one circumferential section of the body portion to a second diameter less than the inflated, first diameter.
