Intended Use

The entré System is intended for use by medical professionals and patients who are under medical supervision, for the treatment of the following conditions: - Chronic edema - Lymphedema - Venous insufficiency - Wound healing

Device Story

The entré Model PD08-U is a pneumatic compression system consisting of a controller and an 8-chambered garment. The garment wraps around an affected extremity; the controller inflates the chambers via an 8-tube harness assembly to provide sequential compression. The device is used in clinical or home settings by medical professionals or patients under supervision. The controller features an internal valve manifold and a front-panel 8-port connector for garment attachment. By applying controlled pneumatic pressure to the limb, the device assists in managing edema and promoting wound healing. Healthcare providers use the system to deliver prescribed compression therapy, which helps reduce fluid accumulation and improve circulation in patients with lymphatic or venous conditions.

Clinical Evidence

Bench testing only. Performance testing included garment chamber pressure testing and cycle time testing to verify equivalence to predicate devices. Additional non-clinical testing included electromagnetic safety (IEC 60601-1-2:2007) and electrical safety (IEC 60601-1:2005).

Technological Characteristics

Compressible limb sleeve system; 8-chamber garment; pneumatic controller with internal valve manifold; 8-port connector. Compliant with ANSI/AAMI ES60601-1, IEC 60601-1 Ed. 3, CAN/CSA C22.2 No. 60601-1, EN 60601-1-2, IEC 60601-1-6, and IEC 60601-1-11.

Indications for Use

Indicated for medical professionals and patients under medical supervision for the treatment of chronic edema, lymphedema, venous insufficiency, and wound healing.

Regulatory Classification

Identification

A compressible limb sleeve is a device that is used to prevent pooling of blood in a limb by inflating periodically a sleeve around the limb.

Dear Daniel Chase.

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug. and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.
