Evaluation of phrenic nerve stimulation trigger lag and synchronization in different modes of ventilation.

Phrenic nerve stimulation is currently being investigated for the prevention of diaphragm atrophy in patients with mechanically supported breathing. Patients receiving breathing support from mechanical ventilation are at risk of mismatches between respiratory demand and ventilator support. Our objectives were to determine if a novel phrenic nerve stimulation device provided stimulation during inspiration as intended and did not exacerbate any potential discordances.

A case series review of spinal cord stimulation migration rates with a novel fixation device.

Introduction: A retrospective review of a consecutive case series of 66 permanent spinal cord stimulation implants utilizing a novel tissue fixation device was performed. The purpose of this case series review is to examine the impact of a novel lead anchor to tissue fixation system and determine if it is a viable alternative to standard tissue fixation methods.

Case Series Report: Sixty-six cases were performed utilizing a novel method of lead anchor tissue fixation.

Effect of a novel fixation method for spinal cord stimulators.

Introduction: Spinal cord stimulation is a well-established treatment for recalcitrant pain syndromes such as failed back surgery syndrome. Techniques minimizing surgical time and incision size and increasing lead stability are of great value to both the patient and implanting physician. We present a consecutive case series review of ten permanent percutaneous spinal cord implants utilizing a novel lead fixation device.

Comparison of a novel fixation device with standard suturing methods for spinal cord stimulators.

Introduction: Spinal cord stimulation is a well-established treatment for chronic neuropathic pain of the trunk or limbs. Currently, the standard method of fixation is to affix the leads of the neuromodulation device to soft tissue, fascia or ligament, through the use of manually tying general suture. A novel semiautomated device is proposed that may be advantageous to the current standard.

Optimizing the effectiveness of a mechanical suture-based anulus fibrosus repair construct in an acute failure laboratory simulation.

Study Design: In vitro comparative, laboratory experiments.

Objective: This study developed a laboratory apparatus that measured resistance to failure using pressures similar to intradiscal pressure of a lumbar spinal disk. Various combinations of an anular repair device were compared.
