First Claim
Patent Images
1. A shaft and sheath 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; 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;
wherein the sheath extends through the inner lumen through a length of the tube and the shaft extends exterior of the inner lumen along the length of the tube in which the sheath extends through the inner lumen, such that a portion of the splitter is positioned between the sheath and the shaft along the length of the tube in which the sheath extends through the inner lumen and the shaft extends exterior of the inner lumen.

16. A shaft and sheath 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; and 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; wherein the sheath extends through the inner lumen through a length of the tube and the shah extends exterior of the inner lumen along the length of the tube in which the sheath extends through the inner lumen, such that a portion of the splitter is positioned between the sheath and the shaft along the length of the tube in which the sheath extends through the inner lumen and the shaft extends exterior of the inner lumen. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A shaft and sheath 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; and a splitter coupled to the hub assembly, the splitter including a tube having a first end, a second end, and a length between the first end and the second end, the splitter including an inner lumen adapted to slidably receive the sheath, and a shaft coupling portion to secure the shaft relative to the hub assembly; wherein the sheath extends through the inner lumen of the splitter and the shaft extends exterior of the inner lumen over the entire length of the tube. - View Dependent Claims (27, 28)
