Overview
Brief Summary
Pilot, randomized, non-blinded clinical trial to generate preliminary data to evaluate the impact of the OsciPulse system on serum d-dimer levels compared to standard of care intermittent compression therapy for DVT prophylaxis in patients admitted in the neuro ICU or intermediate neurological care unit with acute ischemic stroke.
Detailed Description
This is a single site, randomized open label two arm study. The patient population will be randomly divided into two arms, with one receiving the OsciPulse System and the other receiving standard intermittent compression therapy. Both arms will have the therapy applied within 24 hours of admission and continue during their hospital stay until day 7 or discharge, whichever is shorter, unless clinically required to be removed. Daily d-dimer levels will be assessed until day 7 or discharge. If required beyond day 7, standard compression therapy will be provided. An interim analysis will be performed after 20 subjects are enrolled to evaluate the speed of enrollment and data variability and quality. If indicated, enrollment will be increased up to 40.

Outcomes
Primary Outcomes
Change in serum d-dimer levels.
Time Frame: 7 days
Relative change in serum d-dimer levels for each subject from baseline to Day 7 or discharge
Secondary Outcomes
- Tolerability of the OsciPulse device in the stroke population(7 days)
- Safety of the OsciPulse device in the stroke population(7 days)
