Devices for maintaining patency of surgically created channels in tissue
First Claim
Patent Images
1. An implant delivery system for locating and placing the implant within an opening in tissue, the delivery system comprising;
- an elongate shaft having a distal portion, a proximal end, a distal end, and at least one lumen extending through the proximal end;
a guide member located at the distal end of the elongate shaft, where the guide member has a blunt surface such that it may tactilely locate the opening and not drag on tissue or cause trauma;
a balloon member having an interior in fluid communication with the lumen, the balloon member located on the distal portion of the elongate shaft; and
an expandable implant located over the balloon member.

Abstract
Devices and methods for altering gaseous flow within a lung to improve the expiration cycle of an individual, particularly individuals having chronic obstructive pulmonary disease. The methods and devices create channels in lung tissue and maintain the patency of these surgically created channels in tissue. Maintaining the patency of the channels allows air to pass directly out of the lung tissue which facilitates the exchange of oxygen ultimately into the blood and/or decompresses hyper-inflated lungs.
