Pre-curved electrode array loading tools
View Patent ↗Exemplary loading tools configured to facilitate loading of a pre-curved electrode array onto a stylet include a docking assembly, a channel assembly, and a connecting member configured to connect the channel assembly to the docking assembly and maintain a distance therebetween. The docking assembly is configured to couple to the stylet. The channel assembly includes a channel configured to receive and allow passage therethrough of the pre-curved electrode array. The channel is aligned with the docking assembly such that when the stylet is coupled to the docking assembly, the stylet is located at least partially within the channel.
1. A system comprising:
a stylet associated with an insertion tool; and
a loading tool configured to facilitate loading of a pre-curved electrode array onto said stylet, said loading tool comprising:
a docking assembly that couples to said stylet;
a channel assembly comprising a channel that receives and allows passage therethrough of said pre-curved electrode array; and
a connecting member connecting to and integrally formed with said channel assembly and said docking assembly and that maintains a permanently fixed distance therebetween;
wherein said channel of said channel assembly is aligned with said docking assembly such that when said stylet is coupled to said docking assembly, said stylet is located at least partially within said channel.
2. The system of claim 1 , further comprising:
a retainer clip coupled to said channel assembly and movable between a first position that secures said stylet within said channel and a second position that allows removal of said stylet from said channel.
3. The system of claim 1 , wherein said stylet is permanently attached or configured to selectively couple to said insertion tool.
4. The system of claim 3 , wherein said docking assembly comprises one or more notches that mate with one or more corresponding features of said insertion tool.
5. The system of claim 1 , wherein said docking assembly comprises one or more flanges that facilitate handling of said loading tool.
6. The system of claim 1 , wherein said connecting member comprises a c-shaped connecting member.
7. The system of claim 1 , wherein said connecting member comprises a finger grip.
8. The system of claim 1 , wherein said channel assembly further comprises one or more wall members that prevent said electrode array from moving laterally within said channel.
9. The system of claim 1 , wherein said loading tool is made out of at least one of a plastic and a metal.
10. A method comprising:
providing a stylet;
providing a loading tool having a docking assembly configured to couple to said stylet and prevent longitudinal movement of said stylet relative to said loading tool and a channel assembly that comprises a channel configured to receive and allow passage therethrough of a pre-curved electrode array;
inserting a distal tip of said stylet into a proximal portion of a lumen within said electrode array;
coupling said stylet to said docking assembly such that said distal tip of said stylet is located at least partially within said channel; and
advancing said electrode array in a proximal direction relative to said insertion tool and said stylet such that said electrode array moves through said channel and is loaded onto said stylet.
11. The method of claim 10 , wherein said step of advancing said electrode array comprises pulling a proximal portion of said electrode array relative to said loading tool and said stylet.
12. The method of claim 10 , wherein said channel is configured to at least partially straighten said electrode array as said electrode array is advanced.
13. The method of claim 10 , further comprising securing said distal tip of said stylet within said channel.
