Successful diagnosis and treatment of electrical cardiac activity is crucial. Merit Medical offers a range of specialized tools that will assist you in making accurate diagnoses and in creating effective treatment regimes. Features include extra stiff transseptal needles, ergonomic handles for exceptional control, and advanced introducer systems.


HeartSpan Fixed Curve Transseptal Sheath

The HeartSpan® Fixed Curve Transseptal Sheath has a braided steel shaft for excellent torqueability. The tapered dilator and soft, atraumatic tip is designed for enhanced tissue crossing. The embedded platinum marker aids in radiopacity for proper placement. The Fixed Curve Sheath is designed to work in unison with the HeartSpan Transseptal Needle.

HeartSpan Transseptal Needle

The HeartSpan® Transseptal Needle is designed to be exceptionally responsive with enhanced stiffness. The ergonomic handle fits the contours of your hand, for nimble control and navigation. The HeartSpan Needle is designed to work with the HeartSpan Transseptal Sheath.

HeartSpan Steerable Sheath Introducer

The HeartSpan Steerable Sheath Introducer is designed to offer a softer, flexible tip to reduce the risk of atrial wall perforation. The braided construction provides kink resistance and curve durability during Atrial Fibrillation procedures. When navigating cardiac chambers during Electrophysiology (EP) procedures, the sheath is designed to deliver an ergonomic and comfortable control for more precise deflection. The Steerable Sheath is designed to work in unison with the HeartSpan Transseptal Needle.


Prelude SNAP Splittable Sheath Introducer

The Prelude SNAP from Merit Medical features a SMOOTHER sheath-to-dilator transition to reduce vessel trauma and provide ease of insertion through tortuous anatomy. The Prelude SNAP is also EASIER to break, requiring 66% less break force than its predecessor, making it effortless to remove and helping ensure leads stay in place.

Worley Advanced Lateral Vein Introducer

To meet the challenges of cardiac resynchronization therapy (CRT), you need advanced LV leads and LV delivery systems that match the tortuosity of your patient’s anatomy. The Worley Lateral Vein Introducer (LVI) system is designed to offer you the flexibility you need for reliable and accurate placement of LV leads to their target location.

Worley Advanced Coronary Sinus Guide

The unique curve and braided core of the Worley Coronary Sinus Guide (CSG) helps you match your patient’s anatomy to the length and curve of the CSG. The 9 French ID provides ample room to perform various advanced CRT implantation techniques. The braided core inner catheter can be advanced as needed to create variable curves reducing the number of sheaths needed to facilitate a successful implantation.

Worley Vein Selector

The Worley Vein Selector is designed to improve LV lead location with its key features: unique accordion hub to minimize kinking and enhance steerability, proprietary braided shaft to maximize flexibility, and soft tapered tip to reduce vessel trauma. The Worley Vein Selector is also highly visible under fluoroscopy.

Vitale Occlusion Balloon

SVC tears are rare, but when they occur every second counts. The Merit Vitale Occlusion Balloon maintains hemostasis for up to 30 minutes allowing time for patients to stabilize and transition to surgery. Faster inflation, faster deflation, and better kink resistance offers better outcomes for you and your patients.

Vitale Occlusion Balloon - Because Every Second Counts

SafeGuard Focus Compression Device

Achieve targeted hemostasis with SafeGuard Focus, a specialized compression device used to protect closed surgical sites in the immediate postoperative period.* Specifically designed for use in patients with pacemakers and implantable cardioverter defibrillator (ICD) pockets.

SafeGuard Focus with Adhesive - Compression Device for CRM

Worley Advanced Contrast Administration Kit

The Worley Advanced Contrast Administration (CA) Kits combine all the products needed to gain sustained, clear visibility of coronary venous anatomy. The Worley CA Kits provide real-time visibility during CRT implantation for improved LV lead placement.


Learn about Interventional CRT tools and techniques for the implantation of LV leads. Expert faculty utilize didactic presentations and hands-on training to share techniques, including CS cannulation, telescoping, and snaring, which can help improve efficiency and success rates. These courses are designed for electrophysiologists and electrophysiology fellows.
