About this study
Third in-human study for the AtaCor Extravascular (EV) Temporary Pacing Lead System to collect initial safety and performance data for the latest AtaCor System.
The objective of the study is to generate safety and performance data of the latest AtaCor EV Temporary Pacing Lead System 1) to support the development a future pivotal study with an indication limited to a maximum of 7 days, and 2) to obtain early clinical data for future research related to longer-term use.
Read the detailed description
Prior revisions of the study intended to evaluate multiple StealthTrac Leads (Models AC-1010, AC-1020, AC-2021 and AC-1030) to support the development of a future pivotal study. In the most recent revision of the study, an additional StealthTrac Lead (Model AC-1012) will be evaluated to support use in a larger pivotal study.
This study is a feasibility study serving dual purposes: 1) to generate developmental clinical data in support of a subsequent pivotal clinical study and marketing application for temporary pacing (in patients that retain the lead for a maximum of 7 days); and 2) to obtain early data for future research related to longer-term use (in patients that retain the lead for a maximum of 14 days).
Subjects undergoing a qualifying index procedure will have a Model AC-1012 StealthTrac Lead inserted, evaluated for a Maximum Lead Insertion Time prior to removal and a final post-removal follow-up 27-33 days after lead insertion. The following elements will change after the absence of AtaCor-related cardiac tamponade and no more than one (1) serious AtaCor-related pericardial effusion has been confirmed from the initial eight (8) experiences with the Model AC-1012 StealthTrac Lead, including insertion and removal procedures performed by multiple operators:
- Maximum Lead Insertion Time will change from 7 to 14 Days
- Follow-up will change from in-hospital follow-up only to allowing hospital discharge with the StealthTrac lead inserted, but capped and inactive after Day 2 provided in-person wound checks occur at least every 3 days
- Echocardiography requirements will transition from 3 distinct days to procedure day and removal day only.

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Safety - Freedom from Adverse Device Effects (time frame: Lead removal (up to 14 Days)). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jul 2022; AzTrials last refreshed its copy on 30 Oct 2026.
