Abstract: A medical device for electrical stimulation of a patient. A pulse generator generates current pulses for the electrical stimulation. An electrode lead with a plurality of electrode contacts delivers the pulses to tissue of the patient. The pulse generator repeatedly delivers a current pulse between two electrodes forming a first group and delivers a charge balancing current pulse after each current pulse between the electrodes of the first group. The respective current pulse is separated from the succeeding charge balancing current pulse by an inter pulse interval. The respective current pulse has an amplitude with the same absolute magnitude as the succeeding charge balancing current pulse, but is of opposite sign. The pulse generator delivers between each current pulse and the succeeding charge balancing current pulse a current pulse between two further electrodes forming a second group of electrode contacts of the plurality of electrode contacts.

Abstract: A device for neurostimulation includes a pulse generator for generating current having pulses and at least one first pair of electrodes connected to the pulse generator. The device provides a user-programmable therapy strength parameter configuration and at least two current parameter configurations for neurostimulation stored in the pulse generator. The current parameter configurations are controlled by the therapy strength configuration, at least one of the current parameter configurations is associated with a level of paresthesia sensation of a patient and at least one of the current parameter configurations is associated with a paresthesia-free therapy for the patient. The association between therapy strength parameter and current parameter configurations uniquely adjusts the current parameter configurations based on paresthesia or paresthesia-free intent, when neurostimulation is performed using parameter configurations.

Abstract: A system and method for installing/implanting a leadless implant can include a leadless implant with shortened tine-based anchors and an implantation tool with a modified tip. The tines can extend from a surface of the leadless implant and may include a preformed curve or other shape to enable the tine to hook into or grapple tissue.

A tip of the implantation tool can have a reduced inner diameter to cause the tine tips to be approximately normal to the surface of the tissue to which the implant is being anchored. Upon deployment of the leadless implant, the tines of the anchoring mechanism are appropriately aligned for proper insertion so that robust anchoring is achieved.
