Abstract
The present disclosure provides a catheter system and methods for use that includes (a) a first catheter having a first end and a second end, where the first catheter has a first diameter, (b) a second catheter having a first end and a second end, where the second catheter has a second diameter that is less than the first diameter of the first catheter, and where the second catheter is positioned at least partially within a lumen of the first catheter and is moveable relative to the first catheter, and (c) a wire having a first end and a second end, where the first end of the wire is coupled to the second catheter.
Claims38
A catheter system comprising:
- a first catheter having a first end and a second end, wherein the first catheter has a first diameter;
- a second catheter having a first end and a second end, wherein the second catheter has a second diameter that is less than the first diameter of the first catheter, and wherein the second catheter is positioned at least partially within a lumen of the first catheter and is moveable relative to the first catheter such that the second catheter is advanced out of or retracted into the lumen of the first catheter, wherein a wall thickness of a portion of the second catheter at the first end of the second catheter is less than a wall thickness of a portion of the first catheter at the first end of the first catheter, and wherein a stiffness of a portion of the first catheter at the first end of the first catheter is greater than a stiffness of a portion of the second catheter at the first end of the second catheter;
- and
- a wire having a first end and a second end, wherein the first end of the wire is coupled to the second catheter, wherein a wall of the first catheter includes a conduit arranged therein in which the wire at least partially resides, wherein a first end of the conduit abuts the second end of the second catheter when the second catheter is fully retracted to prevent the first end of the second catheter from retracting past the first end of the first catheter and into the lumen of the first catheter.
1 more element
A catheter system comprising:
- a first catheter having a first end and a second end, wherein the first catheter has a first diameter;
- a second catheter having a first end and a second end, wherein the second catheter has a second diameter that is less than the first diameter of the first catheter, and wherein the second catheter is positioned at least partially within a lumen of the first catheter and is moveable relative to the first catheter such that the second catheter is advanced out of or retracted into the lumen of the first catheter, wherein a wall thickness of a portion of the second catheter at the first end of the second catheter is less than a wall thickness of a portion of the first catheter at the first end of the first catheter, and wherein a stiffness of a portion of the first catheter at the first end of the first catheter is greater than a stiffness of a portion of the second catheter at the first end of the second catheter;
- a wire having a first end and a second end, wherein the first end of the wire is coupled to the second catheter;
- and
- an external housing having a conduit is coupled to an exterior of the first catheter, wherein the wire is disposed within the conduit and extends through an opening in a wall of the first catheter to the second catheter.
2 more elements
A catheter system comprising:
- a first catheter having a first end and a second end, wherein the first catheter has a first diameter;
- a second catheter having a first end and a second end, wherein the second catheter has a second diameter that is less than the first diameter of the first catheter, and wherein the second catheter is positioned at least partially within a lumen of the first catheter and is moveable relative to the first catheter such that the second catheter is advanced out of or retracted into the lumen of the first catheter, wherein a wall thickness of a portion of the second catheter at the first end of the second catheter is less than a wall thickness of a portion of the first catheter at the first end of the first catheter, and wherein a stiffness of a portion of the first catheter at the first end of the first catheter is greater than a stiffness of a portion of the second catheter at the first end of the second catheter;
- a wire having a first end and a second end, wherein the first end of the wire is coupled to the second catheter, wherein the second end of the wire is coupled to a threaded knob configured to rotate such that when the wire is unwound from the threaded knob the second catheter is advanced out of the first catheter and when the wire is wound around the threaded knob the second catheter is retracted into the first catheter.
