Abstract
The present invention relates generally to the field of embolic protection and, more particularly, to systems for locking a shaft relative to a hub assembly. In addition, a method for securing a shaft relative to a hub assembly is disclosed.
Claims30
A shaft and wire lock system comprising:
- a sheath having a proximal end, a distal end, and a lumen extending therethrough;
- a shaft having a proximal end and a distal end, wherein at least a portion of the shaft is disposed within the lumen of the sheath;
- a filter coupled to the distal end of the shaft;
- a hub assembly coupled to the sheath;
- a splitter coupled to the hub assembly, the splitter including a tube having an inner lumen adapted to slidably receive the sheath, and a shaft coupling portion to secure the shaft relative to the hub assembly.

A shaft and wire lock system for an embolic protection device, comprising:
- a sheath having a proximal end, a distal end, and a lumen extending therethrough;
- an elongate shaft having a distal end, wherein at least a portion of the shaft is disposed within the lumen of the sheath;
- a filter coupled to the distal end of the shaft;
- a y-adapter coupled to the sheath, the y-adapter having a main lumen and a side lumen;
- a collet disposed at a proximal end of the main lumen;
- a collar coupled to the proximal end of the main lumen;
- a splitter coupled to the y-adapter at the main lumen, the splitter including a tube having an inner lumen adapted to slidably receive the sheath and a shaft coupling portion to secure the shaft relative to the y-adaptor by tightening the collar onto the y-adaptor so as to deform the collet.

A method for securing a wire relative to a shaft, comprising the steps of:
- providing a shaft and wire lock system for an embolic protection device, the system including a sheath having a proximal end, a distal end, and a lumen extending therethrough;
- an elongate shaft having a proximal end and a distal end, wherein at least a portion of the shaft is disposed within the lumen of the sheath;
- a filter coupled to the distal end of the shaft;
- a hub assembly coupled to the proximal end of the shaft;
- and a splitter coupled to the hub assembly, the splitter including a tube having an inner lumen adapted to slidably receive the sheath, and a shaft coupling portion to secure the shaft relative to the hub assembly;
- disposing at least a portion of the sheath within the inner lumen;
- disposing at least a portion of the shaft at the shaft coupling portion;
- and
- securing the shaft relative to the hub assembly such that the sheath is slidable within the inner lumen relative to the shaft.
