When a narrowing sits where a side branch leaves the main artery (a bifurcation), the cardiologist often stents the main branch first, then opens the side branch through the stent struts. MedSure has open cells in its middle segment for this. The struts there can be widened with a semi-compliant or non-compliant balloon such as Glider SC or NC, and a second stent can be passed into the side branch.
Pulse offers four drug-eluting stents. All treat coronary artery disease; they differ in the drug and the design.
| Drug | Struts | Stands out for | |
|---|---|---|---|
| EvroSure | Everolimus (1.1 µg/mm²) | 59 µm, cobalt chromium | Thin struts; polymer fully breaks down in 6–7 weeks |
| MedSure | Sirolimus | 59 µm, cobalt chromium | Open cells in the mid segment for side-branch access |
| Evera | Everolimus | 65 µm strut width | High stent retention on the balloon (dislodgement force over 5) |
| Sirova | Sirolimus | 65 µm strut width | Flexible cells and S-link connectors for twisted arteries |
Pulse supplies the main single-use items for a cath lab, so one supplier answers for supply and documents.
| Pulse product | What it does |
|---|---|
| AcuSafe Micro-Access Introducer Kits | Small-needle first puncture of the artery or vein, then a sheath |
| AcuSafe Introducer Kits | Sheath and dilator that keep the vessel open for catheters and wires |
| GuideX Guidewires | Wires that guide sheaths and catheters into place and support exchanges |
| Optima Manifolds | Control contrast injection, flushing and pressure monitoring |
| Glider PTCA balloons (SC, NC, CTO) | Open the narrowed artery before a stent, and expand the stent fully after |
| Optima Inflation Device Kit | Inflates the balloon to a measured pressure to open the artery and expand the stent |
| Evera, Sirova, EvroSure and MedSure (this page) stents | Drug-eluting stents that hold the opened artery open |
| Mamba drug-coated balloon | Delivers sirolimus to the artery wall without leaving a stent behind |
| AcuSafe Blunt Needle | Controlled access for percutaneous drainage (interventional radiology) |

MedSure is a drug-eluting coronary stent used in angioplasty to hold a narrowed or blocked heart artery open. It releases sirolimus to help stop the artery from narrowing again.
MedSure has open cells in the middle of the stent. A balloon can be passed through them to open a side branch, and a second stent can be placed there if needed.
Diameters of 2.25, 2.50, 2.75, 3.00, 3.50, 4.00 and 4.50 mm, and lengths from 12 mm to 54 mm. The 2.25 mm size goes up to 38 mm long and the 2.50 mm size up to 46 mm.
The nominal pressure is 9 atm and the rated burst pressure is 16 atm. The compliance chart on this page shows the stent diameter at each pressure.
Both release sirolimus. MedSure has thinner 59 µm cobalt chromium struts and open mid-segment cells for side-branch access; Sirova has 65 µm struts and S-link connectors for flexibility.
The MedSure brochure lists ISO 13485:2016 and CE marking (notified body 1035). Ask the Pulse team for the current CDSCO licence and certificates.
