Medtronic™ rotatable connector 5944RL
Medtronic rotatable connector 5944RL provides continuous signal monitoring for SelectSecure™ MRI SureScan™ Model 3830 procedures.
Description
Streamline the Medtronic 3830 procedure experience.
The Medtronic rotatable connector 5944RL is a single-use specialty tool designed to drive procedural efficiencies and guide implant success during Medtronic CSP procedures.
Features
Compatible with the SelectSecure™ MRI SureScan™ Model 3830 lead, the first and only lead CE approved for His bundle pacing and left bundle branch area pacing.
Intended to guide implant success and drive procedure efficiencies with a single point of connection:
- Designed to help achieve target implant location through continuous visualization of ECGs, impedance and 12-lead morphology.
- Eliminates the need to switch between signal monitoring and lead deployment.
- Provide the benefits of a more streamlined and user-friendly procedure.
The rotatable connector is intended to be used with the following Medtronic products:
- Cardiovascular stimulating instruments
- IS–1 leads
- IS–4/DF–4 leads
This device consists of a pair of connection cables, which includes:
- Cathode cable (black wire)
- Anode cable (red wire)
- A pair of shrouded pin adaptors

Frequently asked questions
What are the differences/advantages between 5944RL and alligator clips? Do you have any clinical data to support?
The 5944RL rotatable connector provides a single connection and enables continuous signal monitoring (including EGMs, impedance, COI/Current of Injury), continuous lead deployment and an overall streamlined procedure.
The core performances (mechanical integrity, static impedance and insulation) of 5944RL were tested and proved to be equivalent to the legacy. The unique features of 5944RL (rotational impedance and signal quality under rotation) were also evaluated and proved to meet the clinical use needs.
