Abstract
The present application discloses various methods of constructing hemostasis devices with folded balloon assemblies.
Claims21
A method of constructing a hemostasis device, the method comprising:
- forming a balloon assembly by attaching a top layer of material, a bottom layer of material, and at least one intermediate layer of material together about a perimeter to form at least a portion of a first chamber, the first chamber being inflatable, the at least one intermediate layer creating a gap between the top layer of material and the bottom layer of material adjacent to the perimeter;
- and
- connecting the balloon assembly to a flexible band that is attachable around a body part of a patient.
13-19. (canceled)
A method of constructing a balloon assembly for a hemostasis device, the method comprising:
- depositing a first layer of glue onto a first layer of material;
- curing the first layer of glue to form a perimeter, the perimeter forming at least a portion of an outline of a first chamber, at least a portion of an outline of a second chamber, and at least a portion of an outline of at least one channel that is connected between the first chamber and the second chamber;
- depositing a second layer of glue onto the first layer of material exterior to the perimeter;
- placing a second layer of material on top of the second layer of glue and the first layer of material;
- and
- curing the second layer of glue to attach the second layer of material to the first layer of material and form a contiguous chamber comprising the first chamber, the second chamber, and the at least one channel.

A method of constructing a balloon assembly for a hemostasis device, the method comprising:
- attaching a first layer of material to a second layer of material about a perimeter, the perimeter defining at least a portion of a first chamber, at least a portion of a second chamber, and at least a portion of at least one channel, the at least one channel being in fluid flow communication between the first chamber and the second chamber, the first chamber, second chamber, and at least one channel forming a contiguous chamber;
- and
- locating at least a portion of the first chamber such that it overlays at least a portion of the second chamber and such that the at least one channel is folded.
