What Ob-tools does

OB-TOOLS LTD is an Israel-based, privately held medical device company founded in 2003 by Ob/Gyn Dr. Ilan Calderon to address limitations of traditional tocodynamometry (TOCO) and invasive intrauterine pressure catheters (IUPC). The company develops and commercializes the TrueLabor™ System, a non-invasive platform that uses electrical uterine myography (EUM) to measure uterine contraction frequency, duration, and intensity, and abdominal fetal ECG (fECG) to capture fetal heart rate without Doppler ultrasound. The system comprises a single-use Embrace Sensor, a patient unit, and a monitor unit, and is designed to integrate with existing hospital CTG monitors using waveforms familiar to clinicians, requiring no capital equipment purchases or EMR modifications. Multiple peer-reviewed studies in the American Journal of Obstetrics & Gynecology validate its accuracy — including detection of 39% more contractions than TOCO and patient preference rates of 84% over IUPC and 64.62% over TOCO.

The company targets labor and delivery units in hospitals, with its primary users being maternal fetal medicine specialists and Ob/Gyns managing both routine and high-BMI pregnancies. OB-TOOLS sells directly to hospitals and healthcare facilities via an enterprise field-sales motion, supported by clinical evidence publications and participation in major obstetric conferences (ACOG, AWHONN, MEDICA, DIP). Revenue is generated through hardware system sales plus recurring disposable sensor revenue, though no public pricing or revenue figures have been disclosed. Leadership includes CEO Elon Reshef (veteran biomedical industry executive), President Tamir Ben-David (holder of 90+ patents in implantable devices and signal processing), CTO Dr. Yehuda Sharf (ex-Barnev fetal monitoring), and VP R&D Moni Carmeli (ex-Elbit Systems, INSIGHTEC). The company has no disclosed institutional funding, M&A activity, or regulatory actions on record, and continues to operate as a focused single-product commercial entity at 11-50 employees from its Nesher, Israel headquarters.

The company's competitive posture is anchored on three pillars: (1) a proprietary non-invasive measurement modality that avoids IUPC infection pathways, (2) a peer-reviewed clinical evidence base that supports claims of superior accuracy and patient comfort, and (3) a workflow-friendly integration model that removes the capital-budget and EMR-change barriers typical of new medical device adoption. The disposable Embrace Sensor embeds a consumable revenue layer into otherwise episodic system sales. Strategic positioning is concentrated narrowly in the obstetric monitoring niche with geographic reach signaled through U.S. and European conference activity, though no explicit geographic expansion plan, partnership network, or large customer wins are documented in available materials.

Core offering

Ob-Tools manufactures and sells the TrueLabor™ System, a non-invasive medical device for monitoring uterine contractions and fetal heart rate throughout pregnancy and labor. The system uses proprietary electrical uterine myography (EUM) and abdominal fetal ECG (fECG) technology, and includes the single-use Embrace Sensor, a patient unit, and a monitor unit that integrates with existing hospital monitoring infrastructure.

Product overview

OB-TOOLS offers a single unified product system called the TrueLabor™ System, which consists of three main components: the TrueLabor™ Technology platform, the Embrace Sensor (single-use disposable), and the associated patient and monitor units. The technology uses electrical uterine myography (EUM) to provide non-invasive monitoring of uterine contractions and fetal heart rate. Unlike traditional TOCO (tachodynamometry) which is semi-quantitative or IUPC (intrauterine pressure catheter) which is invasive, TrueLabor™ provides accurate, quantified uterine activity measurements throughout pregnancy and all stages of labor. The system is designed to work with existing hospital monitors and mimic familiar waveforms, requiring no capital budgeting or changes to EMR/IT infrastructure.

Brands

• TrueLabor™ Technology: Non-invasive uterine and fetal monitoring technology that measures uterine contractions and fetal heart rate throughout pregnancy and labor.

Products and services

• TrueLabor™ System A three-part non-invasive monitoring system for labor and delivery departments. It consists of a single-use Embrace Sensor (disposable), a patient unit attached to the disposable, and a monitor unit that receives signals from mother and baby. The system helps clinicians distinguish between true and false labor signs and is designed for hospitals and labor and delivery units.
• Embrace Sensor A single-use disposable sensor used with the TrueLabor™ System. It enables rapid application and start of fetal and uterine monitoring within seconds. It is sold as a recurring revenue consumable for hospitals and labor and delivery units.
• TrueLabor™ Technology A proprietary non-invasive technology platform using electrical uterine myography (EUM) to monitor uterine contractions and fetal heart rate throughout pregnancy and labor. It provides quantitative measurements of contraction frequency, duration, and intensity without invasive procedures.

Quantifiable outcome

• EUM detected 39% more contractions than TOCO in 30-minute tracings

Broad incumbents

• GE Healthcare: Sells the Corometrics series of fetal monitors widely used in L&D units worldwide. Sets the incumbent workflow standard that TrueLabor is designed to integrate with, while also competing through Doppler CTG technology.
• Mindray: Global patient monitoring vendor with fetal monitoring modules integrated into its broader multiparameter monitor platforms. Competes in the same hospital L&D market with bundled capital equipment offerings.
• Philips: Dominant incumbent in the Avalon FM series fetal and maternal monitors, with a deep global installed base in hospitals. Competes indirectly with OB-Tools as the standard TOCO/Doppler solution OB-Tools seeks to displace.

Others

• Huntleigh Healthcare:

Emerging players

• Edan Instruments: China-based patient and fetal monitoring vendor offering cost-competitive CTG solutions. Targets emerging markets and value-segment hospital buyers that overlap with OB-Tools' potential expansion geography.
• Barnev (now part of Nemo Healthcare ecosystem): Prior fetal and labor monitoring venture where OB-Tools' CTO Yehuda Sharf served as VP R&D/CTO. Conceptually adjacent in EMG/EUM-based uterine monitoring and represents an overlapping technology lineage.

Direct peers

• Neoventa Medical: Swedish fetal monitoring company commercializing the STAN method for fetal ECG analysis during labor. Targets the same L&D use case as OB-Tools with an alternative non-invasive/electrical monitoring approach.
• Monica Healthcare: UK-based developer of non-invasive abdominal fetal ECG (fECG) technology for antenatal and intrapartum monitoring. Closest direct competitor to OB-Tools' abdominal fECG component, targeting the same maternal-fetal medicine use case.
• Nemo Healthcare: Netherlands-based company using electromyography (EMG) to non-invasively monitor uterine activity during pregnancy and labor. Directly comparable to OB-Tools' EUM technology and the same clinical positioning versus TOCO and IUPC.

Regional players

• Medigroup Australia: Australian distributor/manufacturer of patient monitoring devices including fetal monitoring consumables, primarily serving Asia-Pacific hospital markets. Indirect competitor with regional reach that overlaps OB-Tools' emerging international expansion.
