PULMONARY OCCLUSAL STENT DELIVERY CATHETER, LOADING SYSTEM AND METHODS OF USE
First Claim
1. A delivery catheter for delivering an implant through a viewing scope into a lung passageway, said catheter comprising:
- an elongate shaft having a proximal end and a distal end, wherein the distal end is configured to releasably hold the implant therein and wherein the outer surface of the distal end comprises a marking which is visible from the viewing scope when the delivery catheter is advanced therefrom and wherein the marker is located on the distal end so that the shaft can be manipulated to align the implant prior to being released.

Abstract
Methods, systems and devices are provided for performing lung volume reduction in patients suffering from chronic obstructive pulmonary disease or other conditions where isolation of a lung segment or reduction of lung volume is desired. The methods are minimally invasive with instruments being introduced through the mouth (endotracheally) and rely on isolating the target lung tissue segment from other regions of the lung and occluding various lung passageways with the use of occlusal stents. The occlusal stents are delivered with the use of an occlusal stent delivery system which is loaded with the occlusal stent with the use of an occlusal stent loading system.

7. A method of introducing an implant into a lung passageway, the method comprising:
-
introducing a viewing scope into the lung passageway; introducing a delivery catheter holding the implant into a lung passageway via the viewing scope, wherein the delivery catheter comprises a distal end with an outer surface having a marking thereon which is visible through the viewing scope when the digital end of the catheter is in the passageway; viewing the marking on the catheter; and deploying the implant. - View Dependent Claims (8, 9, 10)
