A lead for navigating small vessels and a catheter system for implantation of leads into small vessels. Veins that return blood to the heart against the force of gravity often have valves in them to prevent backflow of deoxygenated blood. Leads and catheter systems in accordance with embodiments of the invention allow cannulation and lead implantation in small, tortuous, obstructed, and difficult to access veins enabling a range of stimulation and sensing applications.

Medical lead and implantation

A medical electrical lead and methods of implanting medical electrical leads in lumens. Leads in accordance with the invention employ preformed biases to stabilize the lead within a lumen or lumen and to provide feedback to lead implanters.

Transvascular medical lead

A lead system and method of use for treating breathing disorders by the transvenous stimulation of the phrenic nerve.

Transvenous phrenic nerve stimulation system

A medical electrical lead and methods of implanting medical electrical leads in lumens. Leads in accordance with the invention employ preformed biases to stabilize the lead within a lumen and to orient electrodes in a preferred orientation.

Medical lead with preformed bias

A means for treating breathing disorders by stimulating respiratory muscles or nerves to entrain respiratory systems while leaving respiratory drive intact. Embodiments of the invention employ frequency analysis to determine if appropriate stimulation energy is being applied.

Systems for treating disordered breathing by comparing stimulated and unstimulated breathing

Respiratory rectification

Electrode leads for providing neuromuscular stimulation of the spinal muscles, and methods of implantation of electrode leads, are provided that reduce injury to target muscles, and avoid extended recuperation period, by enabling a clinician to visualize and confirm the implantation site of the electrode leads during an implantation procedure.

Methods of implanting electrode leads for use with implantable neuromuscular electrical stimulator

Medical lead with performed bias

A lead system and method of use for treating breathing disorders by the transvenous stimulation of the phrenic nerve. The lead is implanted in a vein near one portion of the phrenic nerve.
