摘要：
An apparatus and methods to form a tissue scaffolding are provided. The apparatus may include a catheter shaft extending from a proximal end to a distal tip, a distal balloon positioned on the catheter shaft proximal to the distal tip, and a proximal balloon positioned on the catheter shaft proximal to the distal balloon. The apparatus may further include an intermediate balloon positioned on a distal segment of the catheter shaft proximal to the distal balloon and distal to the proximal balloon. The intermediate balloon and the distal segment each include a translucent material. A light fiber may extend through the distal segment. A first lumen and a second lumen may be arranged in the catheter shaft, the first lumen comprising a first port located between the distal balloon and the intermediate balloon, and the second lumen comprising a second port located between the intermediate balloon and the proximal balloon.
