Anastomosis Devices and Methods Utilizing Colored Bands
First Claim
1. An anastomosis device comprising:
- an elongate catheter body having a proximal end and a distal end, an inflation lumen extending through the elongate catheter body from the proximal end to proximate the distal end, and a distal tip defining the distal end;
an inflation balloon proximate the distal end of the elongate catheter body; and
a colored band positioned between the inflation balloon and the distal tip to visually distinguish the distal tip from the inflation balloon, the colored band including a visible colorant such that the an unassisted eye recognizes a visual divide between the distal tip and the inflation balloon.

Abstract
Methods and apparatus for visually distinguishing an inflation balloon from a distal tip of an anastomosis device with an unassisted eye so as to enhance patient safety during an anastomosis procedure. The anastomosis device can comprise a visual reference intermediate the inflation balloon and the distal tip to visually differentiate the distal tip from the inflation balloon. The visual reference can include a colored band to assist a medical profession in determining which portions of the anastomosis device can be grasped or otherwise handled so as to avoid damage to the inflation balloon during manipulation of the anastomosis device such as during removal of the anastomosis device from packaging or during deployment of the anastomosis device during the anastomosis procedure.

10. A method for performing an anastomosis procedure, comprising:
-
providing an anastomosis device having an elongate catheter body having a proximal end, a distal end, an inflation lumen extending through the elongate catheter body between the proximal end and the distal end, and a distal tip defining the distal end, an inflation balloon proximate the distal end; and positioning a colored band between the inflation balloon and the distal tip, the colored band providing a visual distinction to an unassisted eye such that the inflation balloon and the distal tip are visually distinguishable. - View Dependent Claims (11)
