First Claim
Patent Images
1. A valvulotome device, comprising:
- a tubular member having a proximal end, a distal end, a lengthwise axis, and defining a first lumen, the tubular member forming first and second valvulotome arms having radially compressed and radially expanded configurations, each of the first and second valvulotome arms having a u-shaped curved body comprising opposing first and second arms and a base portion extending between the first and second arms, at least one of the first and second valvulotome arms defining a notch having an open end on one of the first and second arms of the u-shaped curved body and extending into the base portion of the u-shaped curved body, the notch defining an angled surface that provides a cutting edge.

Abstract
Valvulotome devices and methods are provided. Valvulotome devices include one or more valvulotome arms that have a u-shaped curved body with opposing arms and a base portion that extends between the arms. The valvulotome arm defines a notch open at one end on one of the arms and extending into the base portion of the u-shaped curved body. The notch defines an angled surface that provides a cutting edge. Methods of making valvulotome devices are also described.

14. A valvulotome device, comprising:
-
an outer tubular member having a first proximal end, a first distal end, a first lengthwise axis, and defining a first lumen, the outer tubular member forming first and second valvulotome arms having radially compressed and radially expanded configurations, each of the first and second valvulotome arms having a u-shaped curved body comprising opposing first and second arms and a base portion extending between the first and second arms, at least one of the first and second valvulotome arms defining a notch having an open end on one of the first and second arms of the u-shaped curved body and extending into the base portion of the u-shaped curved body, the notch defining an angled surface that provides a cutting edge; and an inner tubular member having a second proximal end, a second distal end, a second lengthwise axis, and defining a second lumen, the inner tubular disposed in the first lumen defined by the outer tubular member and forming first and second spacing arms having radially compressed and radially expanded configurations. - View Dependent Claims (15, 16, 17, 18, 19)

20. A valvulotome device, comprising:
-
an outer tubular member having a first proximal end, a first distal end, a first lengthwise axis, and defining a first lumen, the outer tubular member forming first and second valvulotome arms having radially compressed and radially expanded configurations, each of the first and second valvulotome arms having a u-shaped curved body comprising opposing first and second arms and a base portion extending between the first and second arms, the first valvulotome arm defining a first notch having an open end on one of the first and second arms of the u-shaped curved body of the first valvulotome arm and extending into the base portion of the u-shaped curved body of the first valvulotome arm, the first notch defining a first angled surface that provides a first cutting edge, the second valvulotome arm defining a second notch having an open end on one of the first and second arms of the u-shaped curved body of the second valvulotome arm and extending into the base portion of the u-shaped curved body of the second valvulotome arm, the second notch defining a second angled surface that provides a second cutting edge; and an inner tubular member having a second proximal end, a second distal end, a second lengthwise axis, and defining a second lumen, the inner tubular disposed in the first lumen defined by the outer tubular member and forming first and second spacing arms having radially compressed and radially expanded configurations; wherein the first proximal end is positioned flush with the second proximal end; and wherein the outer tubular member is circumferentially oriented about the first longitudinal axis such that each of the first and second valvulotome arms is circumferentially spaced from each of the first and second spacing arms by an angle of approximately 90°
