DELIVERY CATHETER FOR ENDOVASCULAR DEVICE

摘要

Some embodiments relate in part to endovascular prostheses and delivery catheter systems and methods for deploying same. Embodiments may be directed more specifically to graft bodies having self-expanding members, including inflatable graft bodies, and catheters and methods for deploying same within the body of a patient.

主权项

1. A delivery catheter for delivery of an endoluminal prosthesis, comprising:
an elongate shaft with sufficient column strength for percutaneous advancement within a patient's body lumen, the elongate shaft including a proximal section and a lumen extending therein; a plurality of releasable belts disposed on the proximal section of the elongate shaft and configured to releasably constrain a self-expanding member of an endoluminal prosthesis; a plurality of elongate release members in communication with a distal end of the elongate shaft and including a proximal section configured to releasably secure at least one respective releasable belt while said releasable belt is in a configuration that constrains at least a portion of an endoluminal prosthesis; and the elongate shaft comprising an elongate release wire sleeve disposed within the lumen extending within the elongate shaft, the elongate release wire sleeve including a low friction material and extending from a distal section to a proximal section of the elongate shaft, said elongate release wire sleeve comprising a separate lumen for each release member.
