Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The Reveal LINQ Usability Study is a prospective, non-blinded, non-randomized, multi-center clinical trial. Subjects will transmit device data via manual interrogation on a weekly basis during the first month and will be evaluated in the office at 1-month post-implant, in addition to an automatic nightly wireless data transmission using the MyCareLink® home monitor. All subjects will be requested to wear an external Holter for 48 hours at approximately 4 weeks post-insertion. Follow-up visits will continue at 6 and 12 months post-implant, with monthly manual interrogations. Subjects will be exited at their 12 month follow-up visit. The overall study will be conducted in 2 phases which differ primarily on inclusion criteria: Phase I subjects (initial 30 subjects) will have any indication for an ICM, Phase II subjects (all subjects following the initial 30 subjects) will be atrial fibrillation (AF) pre-ablation patients. The study will assess functionality of the Reveal LINQ device by assessing sensing performance and data transmission.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 99 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Subject is willing to sign and date the consent form.
  • Subject is indicated for a Reveal device within the existing market approved indications
  • Phase I (initial 30 subjects): Any indication for a Reveal LINQ Device

  • Phase II (after the initial 30 subjects): Subject has atrial fibrillation and is indicated for and identified as an AF pre-ablation candidate*

    *Note: Atrial fibrillation must be documented in the subject's medical history.

  • Subject has a life expectancy of 18 months or more.
  • Subject is willing and able to set up and utilize MyCareLink® home monitor and be remotely monitored (i.e., Medtronic CareLink® Network)
  • Subjects who are female of childbearing potential (last menses less than 1 year prior to enrolment) must:
  • have a negative pregnancy test at enrollment.
  • not be breastfeeding.

Exclusion Criteria:

  • Subject has an active implanted cardiac medical device (e.g., IPG, ICD, CRT, etc).
  • Subject is unwilling or unable to comply with the study procedures
  • Subject is legally incapacitated and unable to provide written informed consent.
  • Any concomitant condition which, in the opinion of the investigator, would not allow safe participation in the study (e.g., drug addiction, alcohol abuse, emotional/psychological diagnosis)
  • Patient is enrolled in another study that could confound the results of this study, without documented pre-approval from Medtronic study manager.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Insertable Cardiac Monitor Implant
Device: Insertable Cardiac Monitor Implant
The Reveal LINQ is a leadless device that is recommended to be implanted in the region of the thorax. Two electrodes on the body of the device continuously monitor the patient's subcutaneous ECG. The device stores ECG recordings from the patient-activated episodes and ECG recordings from automatically detected arrhythmias. Documentation of episode occurrence will be retained.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Success of Wireless Transmissions
Time Frame: 30 days
To assess the percentage of successful automatic wireless transmissions from the system within the first 30 days of implant.
30 days
R-wave Amplitude
Time Frame: 30 days
To characterize the signal quality of the R-wave amplitude at implant and one month.
30 days
R-wave Amplitudes Greater Than or Equal to 200 μV
Time Frame: 30 days
The proportion of R-wave amplitudes that are greater than or equal to 200 μV will be estimated at implant and one month.
30 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Accuracy of Reveal LINQ Device Detected Atrial Fibrillation
Time Frame: 4 months
To assess atrial fibrillation detection by the Reveal LINQ insertable cardiac monitor (ICM). True and false positives will be reported.
4 months
Safety Endpoint
Time Frame: 12 months
To characterize the system-related and procedure-related adverse events.
12 months
Accuracy of Device Detected Atrial Fibrillation Compared to Holter Monitor
Time Frame: 48 hours
To compare the Reveal LINQ atrial fibrillation detection accuracy with atrial fibrillation detection from Holter monitoring. The true positive rate (sensitivity), specificity, positive predictive value and negative predictive value will be estimated using Holter recordings as the gold standard. Sensitivity measures the proportion of positives that are correctly identified as such. Specificity measures the proportion of negatives that are correctly identified as such. The positive and negative predictive values are the proportion of positive and negative detected patients that are true positive and true negative, respectively. Accuracy measures the proportion of all patients that are correctly identified as negative or positive.
48 hours
Survey of the Implanting Physicians
Time Frame: Day of implant
To understand the implanting physicians' experience with the implant of the Reveal LINQ, and the accompanying implanter tools. Responses to survey questions will be characterized. Below we summarize the responses to survey question "Overall, how would you rate the ease of entire implant procedure?".
Day of implant
Survey of the Patient Experience Over Time
Time Frame: 12 months
To understand the study subjects' experience with the Reveal LINQ, the patient assistant and the patient home monitor. Patient responses to survey questions will be characterized. Below we will summarize the responses to question "Based on your experience to date, please rate your satisfaction with the Reveal LINQ device" over 1 month, 6 month, and 12 month follow-up visit.
