Balloon catheter including braided portions forming perfusion openings
摘要:
A balloon catheter includes a balloon coupled to a shaft. The shaft includes a proximal perfusion portion disposed proximal of the balloon and a distal perfusion portion disposed distal of the balloon. The proximal and distal perfusion portions each are formed by a respective plurality of wire members woven together to form a respective proximal and distal braided shafts. The plurality of wire members are woven together such that a plurality of perfusion openings are formed between the wire members. The plurality of perfusion openings extend from an outer surface of the respective proximal or distal braided shaft to a lumen of the respective proximal or distal braided shaft. A perfusion lumen extends between the proximal perfusion portion and the distal perfusion portion.
