Percutaneous leads with laterally displaceable portions, and associated systems and methods
First Claim
1. A patient treatment device, comprising a lead body that includes:
- a first percutaneous portion carrying a plurality of electrodes and having a first aperture extending into the first percutaneous portion, the first percutaneous portion having a first diameter and a first portion of a bayonet fitting, the stylet;
a second percutaneous portion spaced apart from the first percutaneous portion and having a second aperture extending entirely through the second percutaneous portion, the second percutaneous portion having a second diameter; and
a third percutaneous portion positioned between the first and second portions along a deployment axis and having a third diameter less than the first and second diameters, the third portion having a stiffness in a direction transverse to the deployment axis that is less than a stiffness of the first portion transverse to the deployment axis, and less than a stiffness of the second portion transverse to the deployment axis, the third portion including multiple electrical signal paths between the second portion and the electrodes of the first portion; and
a stylet removably received in the first and second apertures, the stylet having a second portion of the bayonet fitting and the first percutaneous portion being releasably coupled with the bayonet fitting, with the stylet being rotatable about the deployment axis and translatable along the deployment axis relative to the first percutaneous portion between a secured position and an unsecured position.

Abstract
Percutaneous leads with laterally displaceable sections, and associated systems and methods are disclosed. A device in accordance with a particular embodiment includes a lead body that in turn includes first, second and third percutaneous portions. The first portion can carry an electrical contact, the second portion can be spaced apart from the first portion, and the third portion can be positioned between the first and second portions along a deployment axis. The third portion can have a stiffness in a direction transverse to the deployment axis that is less than a stiffness of both the first and second portions transverse to the deployment axis, and a diameter that is less than corresponding diameters of the first and second portions.

16. A patient treatment device, comprising a lead body that includes:
-
a first percutaneous portion carrying multiple electrodes and having a first aperture extending into the first percutaneous portion and a first portion of a bayonet fitting, the stylet; a second percutaneous portion spaced apart from the first percutaneous portion, carrying multiple terminals and having a second aperture extending entirely through the second percutaneous portion; a third percutaneous portion positioned between the first and second portions along a deployment axis, the third portion having a stiffness in a direction transverse to the deployment axis that is less than a stiffness of the first portion transverse to the deployment axis, and less than a stiffness of the second portion transverse to the deployment axis, the third portion including multiple individual wires coupled between individual electrodes and corresponding terminals, the individual wires being movable relative to each other at the third portion, wherein the third portion does not include a shaft disposed around the individual wires; and a stylet removably received in the first and second apertures, the stylet having a second portion of the bayonet fitting and the first percutaneous portion being releasably coupled with a bayonet fitting, with the stylet being rotatable about the deployment axis and translatable along the deployment axis relative to the first percutaneous portion between a secured position and an unsecured position. - View Dependent Claims (17, 18)

19. A patient treatment device, comprising a lead body that includes:
-
a first percutaneous portion carrying multiple electrodes and having a first aperture extending into the first percutaneous portion, the first percutaneous portion having a first diameter a first portion of a bayonet fitting, the stylet and including a first tissue fixation element; a second percutaneous portion spaced apart from the first percutaneous portion, carrying multiple terminals and having a second aperture extending entirely through the second percutaneous portion, the second percutaneous portion having a second diameter and including a second tissue fixation element; and a third percutaneous portion positioned between the first and second portions along a deployment axis, the third portion having a third diameter less than the first diameter and less than the second diameter, the third portion having a stiffness in a direction transverse to the deployment axis that is less than a stiffness of the first portion transverse to the deployment axis, and less than a stiffness of the second portion transverse to the deployment axis, the third portion including multiple individual wires coupled between individual electrodes and corresponding terminals, the individual wires being movable relative to each other at the third portion, wherein the third portion does not include a shaft disposed around the individual wires; and a delivery stylet extending through the second aperture and into the first aperture, with the individual wires arranged externally to the stylet between the first and second portions, the stylet having a second portion of the bayonet fitting and the first percutaneous portion being releasably coupled with the bayonet fitting, with the stylet being rotatable about the deployment axis and translatable along the deployment axis relative to the first percutaneous portion between a secured position and an unsecured position.
