Abstract
A catheter assembly and method includes a multi-lumen portion having a guide wire lumen and an inflation/deployment lumen. The guide wire lumen includes a distal guide wire lumen portion having a rapid exchange guide wire port, and a proximal guide wire lumen portion rotatable to selectively expose the rapid exchange guide wire port. The inflation/deployment lumen includes a rotatable seal which facilitates rotation of the proximal guide wire lumen portion.
Claims24
A catheter assembly comprising:
- a multi-lumen portion comprising a guide wire lumen and an inflation/deployment lumen,
- wherein said guide wire lumen comprises:
- a distal guide wire lumen portion comprising a rapid exchange guide wire port;
- and
- a proximal guide wire lumen portion rotatable to selectively expose said rapid exchange guide wire port.
A catheter assembly comprising an inflation/deployment lumen comprising:
- a distal inflation/deployment lumen portion;
- a proximal inflation/deployment lumen portion;
- and
- a first rotatable seal forming a fluid tight seal between said distal inflation/deployment lumen portion and said proximal inflation/deployment lumen portion.
A catheter assembly comprising:
- a multi-lumen portion comprising a guide wire lumen and an inflation/deployment lumen,
- wherein said guide wire lumen comprises:
- a distal guide wire lumen portion comprising a rapid exchange guide wire port;
- and
- a proximal guide wire lumen portion rotatable to selectively expose said rapid exchange guide wire port;
- and
- wherein said inflation/deployment lumen comprises:
- a distal inflation/deployment lumen portion;
- a proximal inflation/deployment lumen portion;
- and
- a rotatable seal forming a fluid tight seal between said distal inflation/deployment lumen portion and said proximal inflation/deployment lumen portion.
A method of configuring a catheter assembly for use in an over-the-wire mode comprising:
- aligning a distal guide wire lumen portion of a guide wire lumen with a proximal guide wire lumen portion of said guide wire lumen;
- and
- passing a guide wire through a distal end of said guide wire lumen, through said distal guide wire lumen portion and through said proximal guide wire lumen portion.
A method of configuring a catheter assembly for use in a rapid exchange mode comprising:
- rotating a proximal guide wire lumen portion around an inflation/deployment lumen to expose a rapid exchange guide wire port of a distal guide wire lumen portion of a guide wire lumen;
- and
- passing a guide wire through a distal end of said distal guide wire lumen portion, through said distal guide wire lumen portion and out through said rapid exchange guide wire port.
