First Claim
Patent Images
1. A hole-making catheter for creating and dilating an opening within tissue, the catheter comprising;
- an elongate shaft having a proximal portion and a distal portion, and at least one lumen extending through the proximal end;
a nondistensible balloon having an interior in fluid communication with the lumen, the nondistensible balloon located on the distal portion of the elongate shaft,; and
a piercing member located at the distal portion of the elongate shaft, the piercing member being extendable and retractable within the elongate shaft.

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.

-
an elongate shaft having a proximal portion and a distal portion, and at least one lumen extending through the proximal end;
a balloon having proximal end and a distal end and an interior in fluid communication with the lumen, the balloon located on the distal portion of the elongate shaft, and a piercing member located at the distal portion of the elongate shaft, the piercing member being slidable within the elongate shaft such that a distal end of the piercing member may extend distal to a distal end of the balloon and, upon sliding of the piercing member, the distal end of the balloon may be distal to the distal end of the piercing member. - View Dependent Claims (18, 19, 20, 21, 22, 23)

24. A implant delivery system for deploying the implant within a wall of tissue, the system comprising;
-
an elongate shaft having a distal portion, a proximal end, a distal end, at least one lumen extending through the proximal end;
a balloon member having an interior in fluid communication with the lumen, the balloon member located on the distal portion of the elongate shaft;
a piercing member distally located to the distal end of the elongate shaft within the second lumen, the solid piercing member having a sharpened distal end adapted to penetrate tissue; and
an expandable implant located about the balloon member. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
