Intended Use

Used for submucosal aspiration biopsy of the bronchial tree.

Device Story

The Wilson-Cook Lung Biopsy Needle is a sterile, disposable device designed for submucosal aspiration biopsy of the bronchial tree. It is used in conjunction with a bronchoscope, passing through the accessory channel. The device consists of a 22-gauge stainless steel needle, a 100 cm outer catheter made of PEEK (polyetheretherketone), and a handle mechanism. The operator, typically a physician, uses the handle to extend and retract the needle to collect tissue samples via the aspiration port. The device facilitates minimally invasive diagnostic sampling of bronchial tissue, aiding in clinical decision-making for pulmonary conditions.

Clinical Evidence

No clinical data. Substantial equivalence is supported by design verification, including visual, dimensional, and functional testing, and an extensive history of use of the patient-contacting materials in similar medical devices.

Technological Characteristics

Sterile, disposable aspiration needle. Components: 22 GA stainless steel needle, 100 cm PEEK outer catheter with distal metal hub, and handle mechanism. Sensing/actuation: Manual mechanical extension/retraction of needle. Sterilization: Ethylene oxide (EO) cycle per AAMI Standard 11135 (SAL 10^-6).

Indications for Use

Indicated for submucosal aspiration biopsy of the bronchial tree in patients requiring diagnostic tissue sampling.

Regulatory Classification

Identification

A bronchoscope (flexible or rigid) and accessories is a tubular endoscopic device with any of a group of accessory devices which attach to the bronchoscope and is intended to examine or treat the larynx and tracheobronchial tree. It is typically used with a fiberoptic light source and carrier to provide illumination. The device is made of materials such as stainless steel or flexible plastic. This generic type of device includes the rigid ventilating bronchoscope, rigid nonventilating bronchoscope, nonrigid bronchoscope, laryngeal-bronchial telescope, flexible foreign body claw, bronchoscope tubing, flexible biopsy forceps, rigid biopsy curette, flexible biopsy brush, rigid biopsy forceps, flexible biopsy curette, and rigid bronchoscope aspirating tube, but excludes the fiberoptic light source and carrier.
