Pre-curved electrode array insertion tools
First Claim
1. An insertion tool configured to facilitate insertion of an electrode array into a bodily orifice, said insertion tool comprising:
- a stylet assembly comprisinga stylet configured to be inserted into a lumen of said electrode array, anda locking member coupled to a proximal end of said stylet, said locking member comprising a pivot joint and a locking pin disposed within a recess of said pivot joint;
a slide assembly comprisinga docking member comprising an orifice and configured to anchor said stylet assembly to said slide assembly by receiving said locking pin of said locking member within said orifice, anda main body,wherein said slide assembly is configured to at least partially house said stylet assembly within said main body; and
a handle assembly comprising a receptacle and configured to engage at least a portion of said slide assembly by receiving said main body of said slide assembly within said receptacle;
wherein said slide assembly is configured to be selectively and completely removed from said handle assembly in response to a force exerted on at least one of said handle assembly and said slide assembly while said main body of said slide assembly is within said receptacle, said force causing said main body of said slide assembly to completely exit from said receptacle of said handle assembly; and
wherein said stylet assembly, including said stylet and said locking member coupled to said proximal end of said stylet, is configured to selectively disengage from said slide assembly, while said stylet is still inserted into said lumen of said electrode array and while said locking member is coupled to said stylet, in response to a removal by a user of said locking pin from said orifice and a rotation by said user of said locking member after said locking pin is removed from said orifice.

Abstract
Exemplary insertion tools for facilitating insertion of an electrode array into a bodily orifice include a stylet assembly having a stylet configured to be inserted into a lumen of the electrode array, a slide assembly configured to at least partially house the stylet assembly, and a handle assembly configured to engage at least a portion of the slide assembly. The slide assembly may be configured to selectively disengage from the handle assembly. The stylet assembly may be configured to selectively disengage from the slide assembly while the stylet is still inserted into the lumen of the electrode array. Corresponding systems and methods are also described.

1. An insertion tool configured to facilitate insertion of an electrode array into a bodily orifice, said insertion tool comprising:
-
a stylet assembly comprising a stylet configured to be inserted into a lumen of said electrode array, and a locking member coupled to a proximal end of said stylet, said locking member comprising a pivot joint and a locking pin disposed within a recess of said pivot joint; a slide assembly comprising a docking member comprising an orifice and configured to anchor said stylet assembly to said slide assembly by receiving said locking pin of said locking member within said orifice, and a main body, wherein said slide assembly is configured to at least partially house said stylet assembly within said main body; and a handle assembly comprising a receptacle and configured to engage at least a portion of said slide assembly by receiving said main body of said slide assembly within said receptacle; wherein said slide assembly is configured to be selectively and completely removed from said handle assembly in response to a force exerted on at least one of said handle assembly and said slide assembly while said main body of said slide assembly is within said receptacle, said force causing said main body of said slide assembly to completely exit from said receptacle of said handle assembly; and wherein said stylet assembly, including said stylet and said locking member coupled to said proximal end of said stylet, is configured to selectively disengage from said slide assembly, while said stylet is still inserted into said lumen of said electrode array and while said locking member is coupled to said stylet, in response to a removal by a user of said locking pin from said orifice and a rotation by said user of said locking member after said locking pin is removed from said orifice. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. A system, comprising:
-
a pre-curved electrode array configured to provide electrical stimulation to one or more stimulation sites within a duct of a cochlea; and an insertion tool configured to insert said electrode array into said duct of said cochlea, said insertion tool comprising a stylet assembly comprising a stylet configured to be inserted into a lumen of said electrode array, and a locking member coupled to a proximal end of said stylet, said locking member comprising a pivot joint and a locking pin disposed within a recess of said pivot joint, a slide assembly comprising a docking member comprising an orifice and configured to anchor said stylet assembly to said slide assembly by receiving said locking pin of said locking member within said orifice, and a main body, wherein said slide assembly is configured to at least partially house said stylet assembly within said main body; and a handle assembly comprising a receptacle and configured to engage at least a portion of said slide assembly by receiving said main body of said slide assembly within said receptacle; wherein said slide assembly is configured to be selectively and completely removed from said handle assembly in response to a force exerted on at least one of said handle assembly and said slide assembly while said main body of said slide assembly is within said receptacle, said force causing said main body of said slide assembly to completely exit from said receptacle of said handle assembly; and wherein said stylet assembly, including said stylet and said locking member coupled to said proximal end of said stylet, is configured to selectively disengage from said slide assembly, while said stylet is still inserted into said lumen of said electrode array and while said locking member is coupled to said stylet, in response to a rotation of said locking member by a user. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method of inserting a pre-curved electrode array into a bodily orifice, said method comprising:
-
inserting a stylet of a stylet assembly into a lumen of a pre-curved electrode array, said stylet assembly comprising a locking member coupled to a proximal end of said stylet, said locking member comprising a pivot joint and a locking pin disposed within a recess of said pivot joint; providing a slide assembly comprising a main body and configured to at least partially house said stylet assembly within said main body, said slide assembly further comprising a docking member comprising an orifice and configured to anchor said stylet assembly to said slide assembly by receiving said locking pin of said stylet assembly within said orifice; providing a handle assembly comprising a receptacle and configured to engage at least a portion of said slide assembly by receiving said main body of said slide assembly within said receptacle; completely removing said handle assembly from said slide assembly by exerting a force on at least one of said handle assembly and said slide assembly while said main body of said slide assembly is within said receptacle, said force causing said main body of said slide assembly to completely exit from said receptacle of said handle assembly; disengaging said stylet assembly, including said stylet and said locking member coupled to said proximal end of said stylet, from said slide assembly, while said stylet is still inserted into said lumen of said pre-curved electrode array and while said locking member is coupled to said stylet, by removing said locking pin from said orifice and by rotating said locking pin subsequent to said locking member being removed from said orifice; and using said stylet assembly to insert said pre-curved electrode array into said bodily orifice. - View Dependent Claims (15)
