Expandable Balloon Desufflation Assembly

摘要

A balloon dissector includes a cannula, an expandable bladder, and a cord. The cannula defines a lumen between proximal and distal ends. The expandable bladder is configured to expand when fluid is injected into the lumen and includes an inner surface, a proximal base, and a retainer. The proximal base is selectively coupleable to the distal end of the cannula in a sealing relationship. The retainer is positioned on the inner surface of the expandable bladder. The cord includes a first end, a second end, and a central portion. The one end of the cord extends from the proximal end of the cannula. The cord extends through the lumen of the cannula and through the retainer of the bladder returning into the lumen. The cord configured to draw the expandable bladder into the lumen after the expandable bladder is expanded.

1. A balloon dissector comprising:
a cannula defining a lumen extending between proximal and distal ends thereof; an expandable bladder configured to expand when fluid is injected into the lumen, the bladder including:
an inner surface;a proximal base selectively coupled to the distal end of the cannula in a sealing relationship; anda retainer positioned on the inner surface; and a cord having a first end, a second end, and a central portion, at least one of the first and second ends extending from the proximal end of the cannula, the central portion extending from the first end to the second end through the lumen and through the retainer of the bladder, the cord configured to draw a portion of the bladder into the lumen after the bladder is deflated.
