Catheter with balloon material having visual marker
First Claim
Patent Images
1. A balloon catheter for therapeutically treating a patient, comprising:
- a flexible shaft having a proximal end and a distal end;
the shaft defining an inflation lumen;
a balloon affixed to the shaft near its distal end;
the balloon defining an interior and being made of substantially inelastic balloon material;
wherein the balloon is an integral, unitary piece;
the balloon in an initial configuration being deflated, pleated and wrapped around the catheter shaft; and
the balloon in an inflated configuration the balloon having a cylindrical working portion extending between a proximal and distal tapering portion, each of which extend to a proximal and distal balloon collar, respectively;
a hub affixed to the proximal end of the shaft and defining at least an inflation port;
such that the inflation lumen communicates between the hub inflation port and the balloon interior; and
at least one visual marker imprinted on the balloon material which indicates specific information about at least one attribute of the individual balloon catheter.

Abstract
A balloon catheter may have a flexible shaft extending between a proximal and distal end, with a hub affixed to the proximal end, and a balloon made of material that is imprinted with one or more visual markers. The visual marker(s) indicate and confirm specific information about attribute(s) of that individual product.

16. A balloon catheter for therapeutically treating a patient, comprising:
-
a flexible shaft having a proximal end and a distal end;
the shaft defining an inflation lumen;
a balloon affixed to the shaft near its distal end;
the balloon defining an interior and being made of substantially inelastic balloon material;
wherein the balloon has more than one layer, and each layer is an integral, unitary piece;
the balloon in an initial configuration being deflated, pleated and wrapped around the catheter shaft; and
the balloon in an inflated configuration the balloon having a cylindrical working portion extending between a proximal and distal tapering portion, each of which extend to a proximal and distal balloon collar, respectively;
a hub affixed to the proximal end of the shaft and defining at least an inflation port;
such that the inflation lumen communicates between the hub inflation port and the balloon interior; and
at least one visual marker imprinted on an intermediate surface between two of the balloon material layers, which indicates specific information about at least one attribute of the individual balloon catheter. - View Dependent Claims (17)
