INSERTION SYSTEM AND LEAD FOR TREATMENT OF A TARGET TISSUE REGION
First Claim
1. A target tissue insertion system comprising:
- (a) a lead adapted to access a target tissue region associated with a target anatomy;
(b) at least a first insertion tool removably engaged with the lead; and
(c) a second insertion tool surrounding the first insertion tool and removeably positioned internally with respect to the lead;
wherein the target tissue region defines a geometry and the lead defines a curved portion adapted to conform with the geometry of the target tissue region, the lead further being substantially tube shaped having an opening at a distal end and a closed portion at a proximal end, wherein the at least first insertion tool and second insertion tool are adapted to be positioned internally with respect to the lead, the lead still further being fabricated to be substantially soft and flexible having mechanical properties similar to properties of the target tissue region and adapted to curve so as to conform with the geometry of the target tissue region after being inserted into the target anatomy;
wherein the first and second insertion tool in combination is adapted to insert the lead into the target anatomy to engage with the target tissue region; and
wherein the first and second insertion tool combination is removable once the lead is positioned with respect to the target tissue region.

Abstract
The present disclosure provides for systems and methods enabling the insertion of leads (as used e.g., in a framework of the brain treatment therapies) through a target anatomy for conforming with a target tissue region. An exemplary lead includes at least a partially curved portion for conforming with a geometry defined by the target tissue region. In an exemplary embodiment, the system relates to stimulating targets in the brain for improved post-operative steering of an applied electric field. The leads can be either pre-curved or put under transversal mechanical strain during insertion such that a certain curved curvature of the insertion trajectory is achieved. The system includes at least a first insertion tool removably engaged with respect to the lead for guiding and providing mechanical support to the lead during insertion.
