NEW OPPORTUNITIES TO: REDUCE COMPLICATIONS ASSOCIATED WITH TRADITIONAL PACING TECHNOLOGY

Pocket Related Complications

8% at 5 years with traditional technology 1,2

▪ Infection

▪ Hematoma

▪ Erosion

Lead Related Complications

11% at 5 years with traditional technology 1,2

▪ Fractures

▪ Insulation breaches

▪ Venous thrombosis and obstruction

▪ Tricuspid regurgitation

MINIATURIZED

New ultra low power circuit design delivers a 12 year longevity1, 2

▪ Proprietary Li/SVO CFx battery: chemistry has high energy density

▪ Fixation: Stable fixation separated from electrode interface to enable low and stable thresholds. 3

▪ Capture management: Exclusive hourly safety margin confirmation optimizes pacing output

THE MICRA PROCEDURE

SOPHISTICATED PROCEDURE

Engineered for a minimally invasive approach

▪ Integrated delivery system facilitates a streamlined implant procedure via a percutaneous, femoral approach

14

SOPHISTICATED FIXATION

FlexFix™ Tines

▪ Atraumatic, FlexFix nitinol tines provide secure capsule placement1

▪ Four, active nitinol tines gently self expand to ensure consistent deployment

▪ Multidimensional redundancy: 2 tines have 15x the holding force necessary to hold the device in place2

NAVIGATION TO TARGET LOCATION

Minimally invasive, integrated delivery system facilitates a streamlined implant procedure.

DEVICE DEPLOYMENT

Linear, one-step deployment ensures controlled capsule placement, no torque required.1

Catheter is designed to minimize tip force

▪ Femoral approach and flexible distal catheter design result in an 11% push efficiency2
