Intended Use
Model #ECD01-A: The EnsoETM is a thermal regulating device, intended to: · connect to a Gaymar Medi-Therm III Conductive Hyper/Hypothermia System or Stryker Altrix Precision Temperature Management System to control patient temperature, · and provide gastric decompression and suctioning. Model # ECD02-A The EnsoETM is a thermal regulating device, intended to: · connect to a Cincinnati Sub-Zero Blanketrol III Hyper-Hypothermia System to control patient temperature, · and provide gastric decompression and suctioning.
Device Description
The EnsoETM is a multi-lumen silicone tube that is placed in the esophagus in a similar manner to a standard orogastric tube to modulate a patient's temperature, while simultaneously maintaining access to the stomach to allow gastric decompression and drainage, thereby maintaining the functionality of the standard orogastric tube. Modulation and control of patient temperature is achieved by connecting the EnsoETM to an external heat exchanger. Two lumens connect to the external heat exchanger. A third central lumen connects to wall suction and is used for standard gastric decompression. The EnsoETM is made of standard medical-grade silicone. It is a single-use, disposable, non-implantable device with an intended duration of use of 72 hours or less.

No
The summary describes a physical device for temperature regulation and gastric decompression, with no mention of AI or ML technologies in its function or description.

No.
The device's description and intended use focus on regulating patient temperature and providing gastric decompression, which are therapeutic functions. However, the document provided is a premarket submission for an FDA-regulated device, and the question is whether the device is a therapeutic device, not whether it has therapeutic functions. Generally, a therapeutic device is regulated as a medical device for therapeutic purposes within the FDA framework. While the device clearly serves therapeutic purposes, the core function of the device itself, as described by the question, is not inherently therapeutic. Instead, it is connected to a "Hyper/Hypothermia System," which seems to be the therapeutic part.

No

The device is described as a "thermal regulating device" that controls patient temperature and provides gastric decompression and suctioning. Its purpose is therapeutic (temperature modulation, gastric decompression) rather than diagnostic (identifying or characterizing a disease or condition).

No

The device description clearly describes a physical, multi-lumen silicone tube and its connection to external hardware (heat exchangers and wall suction). There is no mention of software as the primary or sole component.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states that the device is for thermal regulating and gastric decompression and suctioning. These are therapeutic and physiological functions performed directly on the patient's body.
  • Device Description: The description details a multi-lumen tube placed in the esophagus and stomach for temperature modulation and gastric access. This is a physical device interacting with the patient's internal environment.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or compatibility testing.

IVD devices are used in vitro (outside the body) to analyze samples to gain diagnostic or other medical information. This device operates in vivo (inside the body) for therapeutic and supportive purposes.

Device Description

The EnsoETM is a multi-lumen silicone tube that is placed in the esophagus in a similar manner to a standard orogastric tube to modulate a patient's temperature, while simultaneously maintaining access to the stomach to allow gastric decompression and drainage, thereby maintaining the functionality of the standard orogastric tube. Modulation and control of patient temperature is achieved by connecting the EnsoETM to an external heat exchanger. Two lumens connect to the external heat exchanger. A third central lumen connects to wall suction and is used for standard gastric decompression. The EnsoETM is made of standard medical-grade silicone. It is a single-use, disposable, non-implantable device with an intended duration of use of 72 hours or less.

Indications for Use (Subject Device 1; Model #: ECD01-A)

The EnsoETM is a thermal regulating device, intended to:

  • connect to a Gaymar Medi-Therm III Conductive Hyper/Hypothermia System or Stryker Altrix Precision Temperature Management System to control patient temperature,
  • provide gastric decompression and suctioning.

Indications for Use (Subject Device 2; Model #: ECD02-A)

The EnsoETM is a thermal regulating device, intended to:

  • . connect to a Cincinnati Sub-Zero Blanketrol III Hyper-Hypothermia System to control patient temperature, and
  • provide gastric decompression and suctioning.

Technological Characteristics

The EnsoETM product family currently consists of two models: the ECD01-A (Predicate Device 1 cleared under K170009) and ECD02-A (Predicate Device 2 cleared under K152450). The purpose of this 510(k) submission is to increase the intended duration of use for the EnsoETM product family from 36 hours to 72 hours. Table 1 describes the differences between the predicate and subject devices. Device characteristics not described in Table 1 are identical for all devices.

Table 1: Differences between EnsoETM models

Subject Device 1 has the identical technological characteristics (including indications for use, patient population, principles of operation, materials, and design) as Predicate Device 1. The only difference is the increase in the intended duration of use from 36 hours to 72 hours.

Subject Device 2 has the technological characteristics (including indications for use, patient population, principles of operation, materials, and design) as Predicate Device 2. The only difference is the increase in the intended duration of use from 36 hours to 72 hours.

Performance Testing

A retrospective analysis of real-world human use data was conducted to demonstrate the subject devices are safe and effective for an intended duration of use of 72 hours by analyzing real-world human clinical data from 18 patients.

Conclusion

The results of all testing and data analysis demonstrate Subject Device 2 are substantially equivalent to Predicate Device 1 and Predicate Device 2 respectively.
