Delivery devices, systems and methods for stimulating nerve tissue on multiple spinal levels
First Claim
1. A delivery device for delivering elements to nerve tissue on different spinal levels, the device comprising:
- a shaft shaped for positioning within an epidural space, wherein the shaft has a first portion having a first opening in the shaft and a second portion having a distal opening and a second opening in the shaft, wherein the first portion is able to move telescopically through the distal opening so as to move the first opening beyond and relative to the second portion so as to adjust the distance between the first and second openings so as to concurrently align the first opening with a first spinal level and the second opening with a second spinal level, andwherein the shaft includes at least one lumen configured to allow passage of at least one element through the first opening toward nerve tissue on the first spinal level and passage of at least one element through the second opening toward nerve tissue on the second spinal level, wherein the at least one element comprises a lead or an agent delivery device.

Abstract
Devices, systems and methods are provided for simultaneously stimulating the spinal anatomy at various locations, such as spinal levels, along the spinal cord. By stimulating multiple levels of the spinal column with the use of a single device, a single access path is created to an implantable pulse generator (IPG) rather than individual access paths for each lead at each spinal level to an IPG. By reducing the number of pathways, the procedure complexity, time and recovery are reduced. In addition, some embodiments provide additional specificity within each targeted level, such as selective stimulation of specific tissue, such as the dorsal root ganglion.

21. A system for treating nerve tissue on different spinal levels, the system comprising:
-
a shaft shaped for positioning within an epidural space, wherein the shaft has a first portion having a first opening in the shaft and a second portion having a distal opening and a second opening in the shaft, wherein the first portion is able to move telescopically through the distal opening so as to move the first opening beyond and relative to the second portion so as to adjust the distance between the first and second openings so as to concurrently align the first opening with a first spinal level and the second opening with a second spinal level, and wherein the shaft includes at least one lumen configured to allow passage of at least one element through the first opening toward nerve tissue on the first spinal level and passage of at least one element through the second opening toward nerve tissue on the second spinal level, wherein the at least one element comprises a lead or an agent delivery device; a first element extendable through the first opening and positionable so as to treat nerve tissue on the first spinal level; and a second element extendable through the second opening and positionable so as to treat nerve tissue on the second spinal level. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
