Abstract: An implantation system and methods of inserting an implant are disclosed. The method includes the step of making an incision in an abdominal wall with an instrument positioned within an abdominal cavity. The method further includes the steps of forming a pocket between a first surface of the abdominal wall and a second surface of the abdominal wall, such that the incision defines an opening into the pocket, inserting an implant through the opening and into the pocket, and closing the opening such that the implant is captured within the pocket.

Abstract: An extravascular neural interface is disclosed containing electrodes for neurostimulation of the vessel. The devices are housed in flexible substrates, each substrate having a spinal portion for routing leads/conductors into the device for connection to the electrodes. Extending from opposite sides of the spinal portion is a self-sizing inner flap that supports and positions the electrodes to be inward facing, i.e., extravascular designs, and one more rigid outer flap. The electrodes may be flexible multifilar coil electrodes.

Abstract: Stimulation of neural activity in a nerve supplying the spleen, wherein the nerve is associated with a neurovascular bundle, can modulate pro- and anti-inflammatory molecules levels, thereby reducing inflammation and providing ways of treating inflammatory disorders. The invention provides improved ways of treating inflammatory disorders which minimize off-target effects.

Abstract: A neurostimulation device 1 for non-destructively stimulating neural activity in a nerve 3 in proximity to a blood vessel 5. The neurostimulation device 1 comprises a catheter 7 for insertion into the blood vessel 5; a proximal electrode 11 offset from a distal electrode 9 along a length of the catheter 7; and an insulator 13 positioned between the proximal electrode 11 and the distal electrode 9 on the catheter 7. The insulator 13 has a contracted configuration in which the size of the insulator 13 allows the catheter 7 to travel inside the blood vessel 5. The insulator 13 has an expanded configuration in which the insulator 13 blocks blood flowing through the blood vessel between the proximal electrode 11 and the distal electrode 9. The neurostimulation device 1 comprises a stimulator 15 arranged to apply an electrical signal between the proximal electrode 11 and the distal electrode 9 when the insulator 13 is in the expanded configuration, thus inducing electrical activity in a wall portion of the blood vessel between the proximal and distal electrodes 9, 11. There is also an insulation portion between the distal electrode 9 and a distal end of the catheter 7 for offsetting the distal electrode 9 from a wall of the blood vessel 5.

Abstract: Modulation of neural activity of a ganglion, by applying a signal to a sympathetic nerve adjacent to the ganglion, results in preferential reduction of sympathetic signals to an effector, thereby providing ways of treating and preventing conditions associated with exacerbated sympatho-excitation.
