Experiences with Sacral Neuromodulation for Urinary Control
Agenda Prevalence & Impact of Overactive Bladder InterStim Therapy for Urinary Control –Efficacy & Safety Information –Test Procedure & System Overview –Medtronic Support Q&A
Overactive Bladder: Prevalence & Impact OAB 1 Asthma 2 Diabetes 3 Osteoporosis 4 Alzheimer’s 5 It is estimated that overactive bladder (OAB) affects more than 33 million people in the U.S. 1 OAB is more prevalent than many well-known diseases. 2-5 The total U.S. economic cost of OAB is $12.6 billion (year 2000 dollars) Serels S.

Patient Survey Data* NAFC survey data found OAB patients seek treatment for the following reasons: –Frustration from living with the symptoms (78%) –Embarrassment (42%) –Physical discomfort (38%) 74% of surveyed OAB patients said they waited longer than they should have to seek treatment Only 20% of surveyed OAB patients are extremely satisfied with their current treatment * Source: Survey for the National Association for Continence (NAFC), sponsored by Medtronic, Inc. and conducted by Kelton Research. April The online survey was conducted using an invitation. Respondents were 611 nationally representative American women ages with overactive bladder.
Pharmacotherapy Persistence & Adherence > 70% discontinuation of prescribed therapy within 6 months > 80% discontinuation of prescribed therapy within 1 year > 50% chose not to restart their therapy after discontinuation 77 % 73 % 82 % OAB medications in the California Medicaid Program 1 1.

1. Yeaw J, Benner JS, Walt JG, Sian S, Smith DB. Comparing adherence and persistence across 6 chronic medication classes. J Manag Care Pharm. 2009;15: Only 28% of patients on OAB medications remained persistent at 6 months Only 18% of patients on OAB medications remained persistent at 1 year Patients were less likely to remain on OAB medications than on any other drug class assessed Pharmacotherapy Persistence & Adherence OAB medications compared to those for several other chronic conditions OAB Medications Prostaglandins Analogs (indicated for glaucoma) Bisphosphonates (osteoporosis) Statins (hyperlipidemia) ARBs (hypertension) Oral antidiabetics (Type II) Persistent at 6 months Persistent at 1 year
Discussion Slide Do these adherence & persistence data reflect what you see in your practice?
InterStim Therapy for Urinary Control An established therapy that expands your treatment options for patients with: urge incontinence, urgency-frequency and non-obstructive urinary retention who have failed or could not tolerate more conservative treatments. More than 85,000 patients worldwide have received InterStim Therapy
1. Medtronic-sponsored research. InterStim Therapy Clinical Summary Insert, % of urge incontinence patients achieved clinical success 45% remained completely dry An additional 34% experienced 50% reduction in leaking 31% returned to normal voids (4 to 7 voids/day) An additional 33% experienced 50% reduction in number of voids 61% eliminated use of catheters An additional 16% experienced 50% reduction in catheterized urine volume 64% of urgency-frequency patients achieved clinical success 77% of urinary retention patients achieved clinical success 12-month clinical success 1 InterStim Delivers Clinical Efficacy Urge Incontinence (n=38) Urgency- Frequency (n=33) Urinary Retention (n=38)

Adverse Events Pain at implant sites New pain Lead migration Infection Technical or device problems Adverse change in bowel or voiding function Undesirable stimulation or sensations The most common adverse events experienced during clinical studies included: Any of these may require additional surgery or cause return of symptoms. For additional safety information, please refer to the Important Safety Information on the last slide of this presentation.
Discussion Slide What level of efficacy do you look for when considering adoption of a new therapy?
Test for Potential Success In-office Test A temporary lead is placed during a simple in-office procedure and connected to an external stimulator You and your patient assess therapy effects for 3-7 days If successful, patient may proceed directly to long-term lead and device implant through an outpatient procedure If test is inconclusive or unsuccessful, the staged test is recommended
Test for Potential Success Utilizes a tined lead to reduce migration Placed in the OR during an outpatient procedure With successful test results, the lead remains in place and the device & lead extension (if applicable) are implanted Complications can occur with the test procedure, including movement of the wire, technical problems with the device, and some temporary pain. Staged Test
Complete InterStim System 1.Tined lead is placed parallel to the sacral (S2, S3, or S4) nerve. 2.Implantable neurostimulator generates mild electrical pulses that are delivered through the lead electrodes. 3.Clinician and patient programmers are used to set the parameters of the electrical pulses
The Pelvic Floor S3, the most distal common point of innervation for the bladder InterStim Therapy stimulates S3 or S4

Discussion Slide Do you believe your patients would be willing to try the temporary test procedure even if they feel unsure about the idea of the long-term implant?
Coverage for InterStim Therapy The coverage profile for sacral nerve stimulation is strong: –Medicare National Coverage Determination –Medicare Local Coverage Determinations (many retired) –Most commercial payers have coverage policies in place Common diagnoses include: – Retention of urine, unspecified – Incomplete bladder emptying – Other specified retention of urine – Urge incontinence – Urinary frequency Medtronic provides this information for your convenience only. It is not intended as a recommendation regarding clinical practice. It is always the provider’s responsibility to determine coverage and submit appropriate codes, modifiers, and charges for the services that were rendered. This document provides assistance for FDA approved or cleared indications. Where reimbursement is requested for a use of a product that may be inconsistent with, or not expressly specified in, the FDA cleared or approved labeling (e.g., instructions for use, operator’s manual or package insert) consult with your billing advisors or payers for advice on handling such billing issues. Some payers may have policies that make it inappropriate to submit claims for such items or related service. Contact your Medicare contractor or other payer for interpretation of coverage, coding, and payment policies.
