5. W e m a k e i d e a s c o m e a l i v e 001IHP050501 For internal use only How does it work? 1/6  Insert 0.014” guidewire through a guiding catheter or long introducer sheath into the renal artery.

6. W e m a k e i d e a s c o m e a l i v e 001IHP050501 For internal use only How does it work? 2/6  Advance slowly the Hippocampus stent system through GC or IS into the renal ostium.  Since the system shows a progressive flexibility, coming from the long tip, followed by the long balloon-cone, the guidewire will not be straightened and possibly flipped out of the ostium! Non-Flip-Tip

7. W e m a k e i d e a s c o m e a l i v e 001IHP050501 For internal use only How does it work? 3/6  Advance slowly the Hippocampus stent system through GC/IS into the renal ostium.  As soon as the balloon segment with the crimped stent is advanced through the curve of the GC/IS, the long tip is already inserted in the ostium so the position cannot be lost again. Progressive Flexibility Superior Vessel Accessibility

8. W e m a k e i d e a s c o m e a l i v e 001IHP050501 For internal use only How does it work? 4/6  Position the stent inside the lesion, so that the proximal 1-2 mm of the stent will overlap into the Aorta. Since it will not shorten, this position can be easily maintained during inflation. Zero Stent-Shortening for Precise Positioning

9. W e m a k e i d e a s c o m e a l i v e 001IHP050501 For internal use only How does it work? 5/6  Inflate the stent carefully, with slow increasing pressure until a proper dilation of the lesion is achieved. High Pressure Balloon for Optimal Results

10. W e m a k e i d e a s c o m e a l i v e 001IHP050501 For internal use only How does it work? 6/6  Flaring the proximal stent section into the ostium is optional, because this might facilitate any following re- intervention of this renal artery. Ostial Scaffolding Capability Facilitating Re-interventions

11. W e m a k e i d e a s c o m e a l i v e 001IHP050501 For internal use only Non-Flip-Tip Non-Flip-Tip  Long Non-Flip-Tip with progressive flexibility and minimal entry profile  Tip length 7mm  6 folded high pressure balloon  Tight FIX  secure crimping

12. W e m a k e i d e a s c o m e a l i v e 001IHP050501 For internal use only Progressive Flexibility  Progressive Flexibility on distal balloon segment starting from the long Non-Flip-Tip followed by the Long Cones provides a superior vessel accessibility. NO balloon overhang! It is the long small angle cone that looks like a balloon overhang! 30°

15. W e m a k e i d e a s c o m e a l i v e 001IHP050501 For internal use only Zero Stent-Shortening  Zero Stent-Shortening and precise alignment of the Stent with the proximal marker band enables the operator to precisely position the stent inside the ostium. Proximal Stent Edge/ Balloon Marker

16. W e m a k e i d e a s c o m e a l i v e 001IHP050501 For internal use only Enhanced Pushability  For the normal RX- sections, there will be an increased friction, when passing through the curve of GC  The Ni-Ti wire is straightening the RX- section in order to transfer the maximum of push through the curve. Push Loss Tapered NiTi-wire inside the 15 cm long rapid exchange section reinforces the distal catheter section and clearly enhances the pushability.

21. W e m a k e i d e a s c o m e a l i v e 001IHP050501 For internal use only Frequently Asked Questions  Why such a long balloon overhang?  It’s no balloon overhang, it is a long cones with a small opening angle for a progressive flexibility from the long Non-Flip-Tip over the Long Cones till the crimped stent segment.  In the common ostial stenting procedures it is NOT acceptable to engage the GC in the ostium, or even advance it through the ostium. NO – TOUCH - PROCEDURE The GC has to remain in front of the renal artery inside the aorta.  Why is the rapid exchange section only 15 cm long?  The SDS is dedicated to renal application, where you only have to reach the renal ostia. That shorter the RX-section is, that higher is the pushability.  What for a NiTi-wire inside the RX-section?  To reduce the friction inside the GC/IS and consequentially improve the pushability.

22. W e m a k e i d e a s c o m e a l i v e 001IHP050501 For internal use only Frequently Asked Questions (cont.)  Are there any clinical data available?  Not yet for the Hippocampus. But we are about to start a multicenter (4) registry “PRECISION” (Renal artery angioplasty in Patients with hypertension and renal insufficiency using Hippocapmus renal stent) with the PI Dr. Thomas Zeller from Germany enrolling 50 patients.  The ostial scaffolding capability is not needed!  Maybe that this operator does not care about any potential re- intervention. But without flaring the ostial section of the stent, the engagement of the ostium with a guidewire can become a very tricky procedure.  Why is the guiding catheter compatibility 6F and the introducer sheath comp. 5F?  A guiding catheter has always the outer diameter indicated. In case a long introducer sheath will be used instead of a GC, the inner diameter of the IS is sufficient with 5F.

23. W e m a k e i d e a s c o m e a l i v e 001IHP050501 For internal use only Positioning  The Hippocampus is a Renal Stent System of the latest generation.  The design and architecture of the stent AND the delivery system is absolutely dedicated to the renal artery approach or similar anatomies (e.g. mesenteric artery).  It is NOT a normal peripheral stent, with a size mix suitable for renal arteries!  Due to the ease of insertion of the stent system into the renal artery, the product has the potential to  reduce the procedural risks  decrease the duration of the procedure  improve the technical success  Hippocampus should be sold on premium price!
