What’s Needed for a Leadless Pacemaker?
• Catheter-based delivery system
• High density energy source
• Low power electronics
• Novel communication scheme
• Biocompatible materials
• Dependable fixation design
• Retrievability capability
Nanostim™ Leadless Pacemaker Makes Possible
Leadless Cardiac Pacing
The Nanostim™ VVIR pacemaker is introduced through the femoral vein
into the right ventricle.
• Energy efficient
– High-capacity CFx battery
– Lower resistance due to lack of lead
– Low-power conductive communication
•
•
Compatible with Merlin™ Patient Care System
Electrode design is identical to a St. Jude
Medical electrode with same steroid elution
• Designed to prevent dislodgement
– Double fixation: single turn helix (x 2 pullstrength) plus angled nylon sutures
– Radiographic indicator to ensure proper number
of turns
•
Tethered test mode for perioperative
evaluation
• Designed for retrievability
– Catheter-based retrieval system
Nanostim: The Device
•
•
Docking feature (A) for delivery, repositioning, and retrieval
Chemical cell (B)
– Standard cell has 3/4 the capacity of improved CFx
– LCP ASIC uses ¼ the current of standard ASICS
– Result: Same longevity with 3/16 the battery volume
•
Compact header (C) with no connector
– Single chip/ASIC senses, paces, and communicates
•
Helix (D) provides primary fixation
– Tines add secondary fixation
•
Electrode w/ steroid(E) paces, senses & communicates
D
E
The Nanostim™ Leadless Pacemaker Delivery System
• Delivery catheter
– Soft, flexible, deflectable catheter tip
designed to minimize complications
– Tethered feature
– Integrated protective sleeve
– 18 F
• Handle with four functions:
–
–
–
–
Steering the deflectable tip
Docking/undocking
Rotating the device
Releasing tether
• 18 F introducer
The Nanostim™ Leadless Pacemaker Retrieval System
• Similar to delivery system
– Flexible with deflectable tip
– Integrated protective sleeve
– 18 F
• Either single loop or triple loop
snare
• Handle with three functions:
1. Steering the deflectable tip for accurate passage
2. Grabbing and docking the LP
3. Rotating the LP
Nanostim™ Programmer Link
Conductive communication via
surface ECG electrodes
– No bulky antenna
– No added circuit module
– 50x less battery current
than RF systems
– Patented technology
First-in-man LEADLESS study
• Objective: Evaluate the safety and performance of the leadless
pacemaker
• Prospective, non-randomized, multicenter study conducted at 3
European centers
• A total of 33 patients were enrolled
–
–
–
–
Mean age of 77 years (53-91 years); 67% male
67% chronic AF and high degree AV block
18% sinus rhythm 2nd /3rd degree AV block with low activity or short lifespan
15% infrequent pauses or unexplained syncope

*In one patient, there was cardiac perforation and tamponade which required surgical repair. On
post-operative day 5 after an uncomplicated surgical repair, the patient (who had atrial fibrillation
and was not adequately anticoagulated) had a large right-sided stroke and ultimately expired.
This event was medically adjudicated.

Miera Transcatheter Pacing Study
One pericardial effusion was observed in a 90-year-otd female
who had undergone 18 repositioning because of inappropriate elec•
trical measurements, the highest number of repositioning observed
in the study. A pericardia( drainage was performed to drain approxi•
mately 250 cc of bload, although no tamponade was diagnosed. The
same patient experienced an acute myocardial infarction 3 days
post-implant and angiography revealed three-vessel coronary artery
disease. Transient complete AV block occurred in four patients and
resolved within seconds to a few hours. Three cases of transient AV
block required pacing via a temporary wire. The fourth resolved
