Spark EM ESWL® — Electromagnetic Lithotripsy System | 140mm Focal Penetration

Spark EM electromagnetic ESWL Lithotripsy System is a non-invasive (non-surgical) procedure that uses focused shock waves to crush stones located in kidneys and ureters. The shock waves produced by the high voltage generator are transmitted directly into the human body by contact from the skin surface via a water cushion. These transmitted shock waves enable the stone to be removed from the body with its disintegrating effect on the stones.

Key Features —

1. Superior Electromagnetic Focusing — Acoustic Lens Technology : The SPARK EM ESWL electromagnetic shock wave system delivers maximum energy to a deep focus with optimal impact ratio, enabling excellent stone fragmentation. This effective feature provides low energy density for non-invasive treatment. Its high accuracy and low wave dispersion values allow for minimal pain and no other complications when applied to internal tissues — zero energy is dispersed into surrounding tissue outside the focal zone. 
2. 140mm Focal Penetration Depth — Focal Penetration: 140mm : Most ESWL systems have focal penetration depths of 100–120mm, which limits their effectiveness in patients with high body mass indexes (BMI) where the distance from skin surface to stone target exceeds this depth. The Spark EM's 140mm standard penetration — extendable to 170mm — makes it clinically effective across the full adult patient weight and body composition range. 
3. High BMI Patient Capability — Industry-Leading Penetration : In Spark EM, the shock head geometry is designed in such a way that the patient can be fully approached to the shock head. In this way, the stones of obese patients can be easily broken.
4. Up to 700 Bar Focal Pressure : Focal Pressure: Up to 700 Bar. 700 Bar focal pressure at the stone target — delivered with zero scatter electromagnetic focusing — provides the powerful stone fragmentation needed for even the most calcified, radio-opaque, and difficult stones while the tight focal zone ensures this pressure is concentrated on the stone with minimal surrounding tissue loading.
5. Dual Imaging: Fluoroscopy + Ultrasound Localisation : The Spark EM combines fluoroscopy (X-ray) and ultrasound stone localisation in a single integrated system — combining the advantages of both imaging modalities:

Fluoroscopy (X-Ray) Advantages:

• Precise visualisation of radio-opaque (calcium-containing) stones
• Real-time stone position tracking during treatment
• Bony landmark reference for stone localisation
• Standard urological imaging familiarity for the operating team

Ultrasound Advantages:

• Detection of radiolucent stones (uric acid stones) invisible on fluoroscopy
• Zero additional radiation exposure during the localisation phase
• Real-time stone fragmentation monitoring — visualising stone disintegration as it occurs
• Kidney parenchyma and collecting system visualisation for anatomical context
• No contrast medium required

The combination of both modalities — selectable according to stone type, patient anatomy, and clinical preference — ensures that every stone type can be localised and targeted accurately, regardless of its composition or radio-opacity.

1. Motorized C-Arm Fluoroscopy — 60° Cranio-Caudal Rotation : The motorised 60° cranio-caudal C-arm rotation — controllable from the treatment console without the operator leaving the control position — enables oblique fluoroscopic views that discriminate stone position from overlying bony structures (ribs, iliac crest, spine), confirm stone-in-focus positioning, and track stone fragmentation from multiple angles during treatment. Remote motor control of the C-arm eliminates the need for the radiographer or urologist to physically reposition the imaging system during treatment.
2. Hand Remote Control Unit — Complete Operational Control : All functions can be controlled from the desired distance with hand control. The handheld remote control unit enables the treating urologist or ESWL technician to control all system functions — C-arm positioning, shock wave energy level, pulse rate, imaging parameters, patient table positioning — from any location in the treatment room.
3. Database System — Patient Records and Treatment Documentation : The integrated database system provides comprehensive patient management capability — recording patient demographics, stone characteristics, treatment parameters, shock wave counts, energy levels, fluoroscopy images, and treatment outcomes across all ESWL sessions. 
4. 1 Million Shot Shock Head Guarantee : The shock head is guaranteed for 1 million shots.

The electromagnetic shock head's 1 million shot lifetime guarantee is a major capital cost differentiator compared to electrohydraulic ESWL systems — where the spark-gap electrode requires replacement every 200–500 shots at significant ongoing consumable cost. At a typical ESWL session of 2,000–3,000 shocks, a 1 million shot electromagnetic shock head provides the equivalent of 333–500 patient sessions before replacement is required, versus 100–250 sessions between electrode changes for electrohydraulic systems. This lower ongoing consumable cost substantially improves the total cost of ownership of the Spark EM over the device's clinical lifetime.
