Intended Use

Synthetic polyisoprene probe covers are indicated for use during diagnostic ultrasound procedures in cases where patient sensitivity to natural rubber latex is speculative.

Device Story

SheathesISO Ultrasound Transducer Covers are thin, conformal, cylindrical synthetic polyisoprene sheaths designed to fit various ultrasound transducer shapes. The device acts as a protective barrier to minimize cross-contamination between the patient and the transducer during diagnostic ultrasound procedures. It is intended for single-patient, disposable use and may be supplied in procedure kits containing elastic fasteners, coupling gel, or needle guides. The device is used in clinical settings by healthcare professionals. By providing a latex-free barrier, it allows for safe ultrasound imaging in patients with suspected natural rubber latex sensitivity.

Clinical Evidence

No clinical data. Evidence consists of bench testing and biocompatibility assessments. Bench testing included viral penetration, stretch testing, pinhole testing, and gel compatibility. Biocompatibility testing included material-mediated pyrogen, cytotoxicity, systemic toxicity, hemolysis, irritation, and sensitization, confirming compliance with ISO 10993-1:2003 for surface-contacting devices in contact with the body for less than 24 hours.

Technological Characteristics

Material: Cis-1,4-polyisoprene (synthetic, latex-free). Form factor: Cylindrical, thin, conformal dip-molded sheath. Energy source: None (passive accessory). Connectivity: None. Sterilization: Sterile and non-sterile options provided. Biocompatibility: Compliant with ISO 10993-1:2003.

Indications for Use

Indicated for patients undergoing diagnostic ultrasound procedures where natural rubber latex sensitivity is a concern.

Regulatory Classification

Identification

A diagnostic ultrasonic transducer is a device made of a piezoelectric material that converts electrical signals into acoustic signals and acoustic signals into electrical signals and intended for use in diagnostic ultrasonic medical devices. Accessories of this generic type of device may include transmission media for acoustically coupling the transducer to the body surface, such as acoustic gel, paste, or a flexible fluid container.

The Sheathing Technologies, Inc CIS-Isoprene Ultrasound Transducer Cover provides a thin, conformal covering to fit various and specific ultrasound transducer shapes. The cover is made by dipping to form a general cylindrical shape. It is closed at the proximal end and open at the distal end for insertion of the ultrasound transducer. This device is an accessory used on diagnostic probes to help minimize cross contamination.

The cover material is a Cis-1,4-polyisoprene, a synthetic version of natural rubber latex made without using natural rubber latex in the formulation. Various sizes and shapes of covers are offered to address the variations in Ultrasound Transducer configurations.

Product categories/models include

- 1. General Purpose SheathesISO Ultrasound Transducer Covers (sterile and non-sterile)
Covers are packaged in both sterile and nonsterile, individually wrapped or in bag/box quantities, as well as in "procedure kit" form for single patient/procedure, disposable use. The "procedure kit" may include elastic fasteners, with or without coupling gel packets. Transducer covers are also combined with disposable needle guide devices into kits.

Substantial Equivalence:

Non-Clinical Tests:

The Sheathing Technologies, Inc. CIS-Polyisoprene Ultrasound transducer cover is identified as substantially equivalent to CIVCO's current, legally marketed NeoFlex™ Ultrasound Transducer Covers and CIVCO's Synthetic Polyisoprene Ultrasound Transducer Cover.
