Abstract
A multi-purpose vascular device defines a lumen allowing fluid communication there through and has a coil with a side of the coil winds having solid physical connections between the coil winds to prevent the connected coil wind side from expanding following the application of force by an actuating member which causes the connected coil winds to have a predetermined configuration in an unstressed state. The application of longitudinal force causes the unconnected coil winds to expand, resulting in the vascular device assuming a different configuration.
Claims19
A vascular device, comprising:
- a flexible shaft having a length, a lumen extending in a linear manner the length of the shaft and defining first and second open ends allowing unrestricted fluid communication through the lumen, a proximal section and a distal section;
- the distal section comprising a coil comprising a plurality of coil winds defining an outer periphery and a central space, the distal section having a weak side and a strong side;
- and
- an actuating member attached to the outer periphery of the distal section, the actuating member capable of transmitting longitudinal force to the distal section;
- wherein applying longitudinal force to the actuating member causes the weak side of the distal section to increase in length while the strong side maintains substantially the same length, resulting in the distal section deflecting.
A vascular device, comprising:
- a flexible shaft having a lateral dimension, a length, a proximal section, a distal section having greater flexibility than the proximal section and a lumen extending in a linear manner the length of the shaft and defining first and second open ends allowing unrestricted access between first and second open ends of the lumen;
- a helical coil comprising a plurality of coil winds at least partly defining the shaft, the coil having an outer periphery and a distal end;
- an actuating member attached to the outer periphery of the coil, the actuating member capable of transferring longitudinal force to the coil;
- and
- at least two of the coil winds being physically connected by the actuating member, defining a connected side, to maintain the coil winds on the connected side in a constant configuration preventing differential spacing resulting from the application of longitudinal force and causing the connected coil winds to have a predetermined configuration in an unstressed state;
- wherein the application of longitudinal force to the actuating member causes an unconnected side of the coil winds to expand, resulting in the vascular device assuming a stressed configuration having a different shape than the vascular device in the unstressed configuration.
A vascular device comprising:
- a distal shaft section having an expandable side and a non-expandable side, the distal shaft section comprising a coil defining a first central space and comprising a plurality of coil winds, and an external flat section on the plurality of coil winds;
- a proximal shaft section defining a second central space coaxial with the first central space;
- a lumen defined by the first central space and the second central space, the lumen having first and second open ends allowing unrestricted fluid communication through the lumen;
- a ribbon attached to the external flat section of each of the plurality of coil winds;
- and
- an actuating member attached to the distal shaft section and capable of transferring longitudinal force to the coil.
