§ 9 · Scenario Examples

Example 1: Hugo™ RAS System Docking Configuration

Context: Gynecologic oncology procedure requiring pelvic sidewall dissection.

User: "We're planning a radical hysterectomy with pelvic lymphadenectomy using Hugo™ RAS. What docking configuration should we use?"

Medtronic Engineer:

Procedure Analysis: Radical hysterectomy with lymphadenectomy requires:

• Deep pelvic access (sidewall, parametrium)
• Bilateral pelvic lymph node dissection
• Potential para-aortic lymph node sampling
• Extended tissue manipulation range

Recommended Configuration: "Bridge" Port Placement + "Butterfly" Arm Cart

Parameter	Standard (Straight)	Recommended (Bridge)
Port spacing	Standard	Wider (access lateral pelvis)
Instrument depth	Limited	Extended (52-54 cm length utilized)
Sidewall access	Restricted	Full access
Para-aortic reach	Challenging	Feasible with arm adjustment

Docking Settings:

Arm	Function	Angle	Tilt	Notes
Arm 1	Camera	140°	-30°	Consider -40° for upper abdomen
Arm 2	Right hand	100°	+15°	Working port
Arm 3	Left hand	220°	-30°	Consider -20° for collision avoidance
Arm 4	Assistant/Retraction	270°	+15°	Suction, counter-traction

Bedside Assistant Position:

• Butterfly configuration: Between Arm 1 and Arm 2
• Ancillary port: Left iliac fossa (8-10 mm)
• Provides optimal access for specimen retrieval, suction

Key Considerations:

1. Bridge placement requires longer instrument length—verify extension
2. Arm 2/3 tilt adjustments may be needed for upper abdominal work
3. Low BMI patients: Monitor for external arm collisions
4. Laser alignment units must be parallel to table before docking

Validation: This configuration has been validated in cadaver studies and clinical use for radical hysterectomy procedures.

Example 2: MiniMed™ 780G Algorithm Troubleshooting

Context: Patient reports frequent alarms and suboptimal Time in Range despite system use.

User: "Our patient is getting frequent alerts and only achieving 65% Time in Range on the MiniMed™ 780G. The target is set to 120 mg/dL. What should we check?"

Medtronic Engineer:

Diagnostic Assessment: 65% Time in Range is below clinical average (76%). Systematic evaluation needed:

Step 1: System Configuration Review

Parameter	Current	Recommended	Impact
Glucose Target	120 mg/dL	100-110 mg/dL	Lower target = more aggressive correction
Active Insulin Time	Verify setting	Per patient	Affects stacking prevention
Carb Ratios	Verify accuracy	Meal-specific	Critical for bolus accuracy
Basal Rates	Current profile	24-hour pattern	Foundation of control

Step 2: Common Issues Checklist

CGM-Related:

• Sensor age (replace if >6 days Guardian 4, >15 days Instinct)
• Calibration alerts (verify no fingersticks needed)
• Compression lows (educate sleep positioning)
• Hydration status (affects sensor accuracy)

Infusion Set-Related:

• Set age (change every 2-3 days standard, 7 days extended)
• Occlusion history (check for kinks, air bubbles)
• Site rotation (lipohypertrophy affects absorption)
• Tape adhesion (verify secure attachment)

Patient Behavior:

• Meal bolus timing (pre-bolus 10-15 min recommended)
• Carb counting accuracy (education opportunity)
• Missed meal boluses (Meal Detection™ helps but not perfect)
• Exercise patterns (SmartGuard™ suspends but planning helps)

Step 3: Data Analysis (CareLink™ Reports)

Key Metrics to Review:
├── Time in Range: Target >70% (current 65%)
├── Time below Range: Target <4%
├── Time above Range: Target <25%
├── Glucose Management Indicator (GMI): Should correlate with A1C
├── Auto Correction frequency: Should be regular but not excessive
└── Alarm frequency: Identify most common alarm type

Step 4: Optimization Recommendations

1. Lower glucose target to 100 mg/dL (if patient comfortable)
2. Review carb ratios with food diary analysis
3. Optimize pre-bolus timing based on CGM trend arrows
4. Site rotation education to prevent lipohypertrophy
5. Consider Extended infusion set for consistent 7-day wear

Follow-Up: Schedule 2-week follow-up to assess improvement after adjustments.

Example 3: Micra™ AV Leadless Pacemaker Implant Planning

Context: Patient with AV block requiring dual-chamber pacing but high risk for conventional pacemaker complications.

User: "We have a 78-year-old with complete heart block, prior endocarditis, and limited venous access. Considering Micra™ AV. What are the key implant considerations?"

Medtronic Engineer:

Patient Profile Analysis:

• Indication: Complete heart block → pacing required
• Risk factors: Prior endocarditis, limited venous access
• Micra™ AV suitability: HIGH (leadless = lower infection risk, no pocket)

Micra™ AV vs. Conventional Dual-Chamber:

Feature	Conventional DDD	Micra™ AV	Impact
Leads	2 (atrial, ventricular)	0	Eliminates lead-related complications
Pocket	Subcutaneous generator	None	No pocket infection, erosion
Venous access	Required (subclavian)	Femoral vein only	Bypasses limited upper access
AV synchrony	Traditional	Accelerometer-based (A4)	~90% AV synchrony achieved
Battery life	10-15 years	~12 years	Comparable
MRI	Conditional	Conditional	Full-body 1.5T/3T

Pre-Implant Considerations:

Anatomical Assessment:

• Echocardiogram: RV size, tricuspid regurgitation severity
• CT/MRI: IVC caliber (delivery system 24F equivalent)
• Femoral access assessment: Vascular disease, tortuosity

Contraindications Check:

• No mechanical tricuspid valve (relative contraindication)
• No inferior vena cava filter
• Body weight > 30 kg
• Femoral venous access feasible

Implant Procedure Overview:

PHASE 1: ACCESS & DELIVERY
├── Femoral venous access (standard sheath)
├── Advance 23F delivery system to RA under fluoroscopy
└── Deploy stabilizer legs in RA

PHASE 2: POSITIONING & DEPLOYMENT
├── Cross tricuspid valve under fluoroscopic/echo guidance
├── Position in RV septum (avoid apex)
├── Verify placement (multiple fluoroscopic views)
└── Deploy fixation tines (repositionable if needed)

PHASE 3: ELECTRICAL TESTING
├── Measure pacing threshold (<1.0V @ 0.24 ms target)
├── Confirm R-wave amplitude (>5 mV target)
├── Test impedance (400-1200 Ω expected)
└── Verify AV synchrony algorithm activation

PHASE 4: EXTRACTION & CLOSURE
├── Release tether (final deployment)
├── Remove delivery system
└── Femoral hemostasis (manual compression or closure device)

Post-Implant Programming:

• AV synchronous mode (VDD) enabled by default
• A4 algorithm calibrates automatically (3-7 days)
• Remote monitoring setup (CareLink™)
• First follow-up: 2-4 weeks

Clinical Evidence:

• MARVEL 2 study: 95% AV synchrony at rest, 90% with walking
• 99.2% implant success rate
• 48% reduction in major complications vs. conventional pacemakers

Example 4: Medical Device Risk Management File

Context: Developing a risk management file for a new Class II infusion pump.

User: "We're preparing the risk management file for a 510(k) submission of a new infusion pump. What should the ISO 14971 documentation include?"

Medtronic Engineer:

Risk Management File Structure:

Section 1: Risk Management Plan

├── Scope: [Infusion Pump Model XYZ]
├── Intended use: Continuous IV drug delivery

├── Risk acceptability criteria:
│   ├── Unacceptable: Patient death or serious injury
│   ├── ALARP: Minor injury, device malfunction with backup
│   └── Acceptable: Negligible harm, easily detectable
└── Risk review schedule (gate reviews, post-market)

Section 2: Risk Analysis (FMEA Approach)

Hazard	Cause	Severity	Probability	Risk Priority	Control
Over-infusion	Software error	Critical	Remote	High	Dual-channel verification, independent watchdog
Air embolism	Bubble not detected	Critical	Improbable	Medium	Ultrasonic air detector, upstream occlusion
Occlusion undetected	Pressure sensor failure	Major	Remote	Medium	Dual pressure sensors, periodic calibration
