Steerable stylet handle assembly
First Claim
1. A steerable stylet handle assembly, comprising:
- a housing having first and second side walls defining a channel therebetween;
a button in communication with said first and second side walls and configured to move distally and proximally within said channel;
a stylet subassembly comprising an outer tubing and an inner stylet wire located at least partially within the outer tubing, said inner stylet wire having a pre-curved distal portion;
wherein a proximal portion of said inner stylet wire is coupled to a proximal portion of said housing and a proximal portion of said outer tubing is coupled to said button and configured and arranged so that movement of the button distally and proximally within the channel results in a corresponding movement of the outer tubing; and
wherein movement of said button within said channel is configured to move the outer tubing to selectively expose and cover at least a portion of said pre-curved distal portion of said inner stylet wire with said outer tubing.

Abstract
An exemplary steerable stylet handle assembly includes a housing having first and second side walls defining a channel therebetween, a button in communication with the first and second side walls and configured to move distally and proximally within the channel, and a stylet subassembly having an inner stylet wire located at least partially within an outer tubing. The inner stylet wire has a pre-curved portion and is coupled to a proximal portion of the housing. The outer tubing is coupled to the button. Movement of the button within the channel is configured to selectively expose and cover at least a portion of the pre-curved distal portion of the inner stylet wire with the outer tubing.

11. A system for facilitating stimulation of a stimulation site within a patient, said system comprising:
-
a lead having at least one electrode disposed thereon; and a steerable stylet handle assembly configured to implant said at least one electrode at said stimulation site comprising a housing having first and second side walls defining a channel therebetween; a button in communication with said first and second side walls and configured to move distally and proximally within said channel; a stylet subassembly configured to be inserted within said lead and comprising an outer tubing and an inner stylet wire located at least partially within the outer tubing, said inner stylet wire having a pre-curved distal portion; wherein a proximal portion of said inner stylet wire is coupled to a proximal portion of said housing and a proximal portion of said outer tubing is coupled to said button and configured and arranged so that movement of the button distally and proximally within the channel results in a corresponding movement of the outer tubing; and wherein movement of said button within said channel is configured to position said at least one electrode at said stimulation site by moving the outer tubing to selectively expose and cover at least a portion of said pre-curved distal portion of said inner stylet wire with said outer tubing. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A method, comprising:
-
providing a housing having first and second side walls defining a channel therebetween; providing a button in communication with said first and second side walls and configured to move distally and proximally within said channel; providing a stylet subassembly comprising an outer tubing and an inner stylet wire located at least partially within the outer tubing, said inner stylet wire having a pre-curved distal portion; coupling a proximal portion of said inner stylet wire to a proximal portion of said housing; coupling a proximal portion of said outer tubing to said button so that movement of the button distally and proximally within the channel results in a corresponding movement of the outer tubing; and moving said button within said channel to move the outer tubing to selectively expose and cover at least a portion of said pre-curved distal portion of said inner stylet wire with said outer tubing.
