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.
Claims16
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 first 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 first lumen;
- a helical coil comprising a plurality of coil winds at least partly defining the shaft, the coil having an outermost periphery and a distal end;
- an actuating member capable of transferring longitudinal force to the coil, the actuating member defining a second lumen, with the first lumen between the helical coil and the actuating member;
- and
- at least two of the coil winds being physically connected at the outermost periphery of the coil by a fixing structure directly connected to the outermost periphery of the at least two of the coil winds, 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 state.
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, the plurality of coil winds defined by a first outer radius when viewed in a longitudinal direction and having an external flat section on the plurality of winds defined by a second outer radius when viewed in the longitudinal direction, the second outer radius being smaller than the first outer radius;
- 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 fixing structure attached directly to the flat section on the outermost periphery 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.
