Long stents early result Biomechanical stress Conformability missmatch: arterial wall- stent late result Stent- fracture Intimal hyperplasia Restenosis: LLL Occlusion Re-do Costs

Accepted problems with Stenting 1. changes in biomechanical properties and chronical inflammation of stented segement /artery  stent fracture  intimal hyperplasia  late lumen loss problems increase with length of treated vessel segment = Stent- disease long lesion  long stent  problem  „leave nothing behind“ ©

Concept of focal stenting  Calcified lesions demand ongoing mechanical stabilisation of initial balloon-result: mandatory scaffolding  DEB, Tack-it, BVS and DBVS alone do not solve this problem  There is still a need for permanent scaffolding:  long lasting  with a reduced mass of foreign body (as few as possible)  = focal- spot / taget- stenting

radial force / stentdesigns Newton (N) Design - Stent-Größe Conclusion: 1. Animal experiments show technical feasibility of the multi stent delivery system (MSDS): Multi-Loc. 2. Exact anatomically controlled implantation of short stents is possible. 3. Short stents in actively bended arterial segments do not fracture (0 vs 5). 4. Patency of arterial segments after stenting with 4-5 short individual stents is superior to single long stent implantation in all animals.
