Abstract
A hypotube for an intravenous catheter device is disclosed which includes a tubular shaft having a tubular wall defining a lumen. The shaft includes a main section integrally connected to a distal section. The distal section includes a first section connected to the second section and disposed between the second section and the main section. The second section includes an elongated stinger.
Claims75
A hypotube comprising:
- a tubular shaft comprising a tubular wall defining a lumen and a main section connected to a distal section,
- the distal section comprising a first section connected to a second section, the first section being connected to the main section and disposed between the main section and the second section,
- the first section comprising at least one slit extending at least partially through the tubular wall,
- the second section comprising an elongated stinger formed by a portion of the tubular wall.
A catheter apparatus comprising:
- the hypotube comprising a tubular shaft comprising a tubular wall defining a lumen and a main section integrally connected to a distal section,
- the distal section comprising a first section integrally connected to a second section, the first section being integrally connected to the main section and disposed between the main section and the second section,
- the first section comprising at least one slit extending at least partially through the tubular wall,
- the second section comprising an elongated stinger formed by a portion of the tubular wall.
A method for fabricating a hypotube for an intravenous device, the method comprising:
- providing a tubular shaft comprising a tubular wall defining a lumen and a main section integrally connected to a distal section,
- cutting a first section of the distal section that is disposed between and integrally connected to the main section and a second section to provide at least one slit extending at least partially through the tubular wall for of the first section,
- cutting the second section to provide an elongated cut-out of the tubular wall and an elongated stinger formed by a portion of the tubular wall of the second section.
A hypotube comprising:
- a tubular shaft comprising a tubular wall defining a lumen and a main section connected to a distal section,
- the distal section comprising at least one slit extending at least partially through the tubular wall,
- the distal section further comprising an elongated cut-out of the tubular wall which forms an elongated stinger.
A method for fabricating a hypotube for an intravenous device, the method comprising:
- providing a tubular shaft comprising a tubular wall defining a lumen and a main section integrally connected to a distal section,
- cutting the distal section to provide at least one slit extending at least partially through the tubular wall for of the distal section for increasing flexibility of the distal section,
- cutting the distal section to provide an elongated cut-out of the tubular wall and at least one elongated stinger formed by a remaining portion of the tubular wall of the distal section.
A hypotube comprising:
- a tubular shaft comprising a tubular wall defining a lumen and a main section connected to a distal section,
- the distal section comprising at least one slit extending at least partially through the tubular wall,
- the distal section further comprising a distal end connected to a stinger element.
