Filed:

Mar 2, 2007

Appl. No.:

11/713360

Inventors:

David Pirie - Marlborough CT, US

International Classification:

B42D 5/00

US Classification:

283 72

Abstract:

A method for imprinting documents imprints visible printed matter on multiple pages of imprintable material and including visible control indicia in one of the marginal portions. The visible control indicia are scanned and data is transmitted to a computer which then imprints on the pages in invisible ink invisible control indicia associated with the visible control indicia. Subsequently, an energy source is applied to the invisible control indicia to render the control indicia discernable to a scanner. The discernable control indicia is scanned to generate data sent to a computer where it is compared with information stored in the computer to determine that the pages conform to stored parameters. Further operations on the pages in which the invisible control indicia are activated may be conducted by reading the data in the invisible control indicia.

Abstract:

Embodiments of a balloon assembly are disclosed. The balloon assembly can include an inflatable balloon having an inflated state and a deflated state. The balloon in the deflated state can include a valve retaining portion, a distal tapered portion connected to a distal end of the valve retaining portion, a proximal tapered portion connected to a proximal end of the valve retaining portion, a distal leg connected to the distal end of the distal tapered portion, and a proximal leg connected to the proximal end of the proximal tapered portion. The distal tapered portion can include one or more axial folds. The proximal end of the distal tapered portion can include a first radial fold connected to a second radial fold, the first and second radial folds forming a pocket extending distally at the proximal end of the distal tapered portion.
