The purpose of this study is to demonstrate feasibility to access, visualize, and obtain specimens adequate for cytology of lung lesions in subjects with suspected lung cancer when using the iNod System.

This protocol is a traditional feasibility study for the sampling of a peripheral pulmonary lesion in the setting of a suspicion of lung cancer. Standard of practice radial endobronchial ultrasound (R-EBUS) transbronchial needle aspiration (TBNA) is visualizing a peripheral lesion on R-EBUS, locking the placement of the access sheath, removing the ultrasound catheter from the access sheath and then blindly advancing a sampling device to acquire cellular matter for cytologic evaluation. The iNod system performs the same procedure with one fewer device exchange. It provides real-time visualization of the biopsy needle and target peripheral pulmonary lesions during tissue acquisition. The ultrasound probe is not retracted in advance of the sampling maneuver and the sampling is completed under direct visualization. Compared to current standard of care methods for transbronchial sampling of pulmonary lesions, this approach is not expected to add additional risk. Tissue sampling under real-time visualization may improve the efficiency of tissue sampling.

Inclusion Criteria:

1. Subject is age 18 years or older.
2. Subject is willing and able to comply with study procedures and provide written informed consent to participate in study.
3. Subject with a predominantly solid lung lesion, 1 cm to 7 cm in diameter, which has been identified on chest CT (obtained within 6 weeks) with the intention to undergo a clinically indicated bronchoscopic evaluation under routine clinical care. If the lesion is partially solid (i.e. there is a ground glass component) then the solid portion must make up 80% of the lesion.
4. Subject for whom the decision to pursue biopsy has been made by the treating physician and agreed upon by the subject.

Exclusion Criteria:

1. Subjects with pure ground glass opacity, a subsolid target lesion, and/or a ground glass opacity identified on Chest CT.
2. Subjects with lesions that include endobronchial involvement, per Chest CT.
3. Subjects who lack fitness to undergo flexible bronchoscopy and standard of care Radial EBUS-guided cytological assessment evaluations, as determined by the investigator.
4. Subjects with known coagulopathy.
5. Subjects who are pregnant or nursing mothers.
6. Subjects who are currently enrolled in another investigational study that would directly interfere with the current study, without prior written approval from the sponsor.

23 Patients were analyzed for primary endpoint. 86 Attempts to access target lesions were analyzed.

Adverse event data was collected from the Baseline/Consenting Visit, through study exit; typically 7 days.

Any untoward medical occurrence, unintended disease or injury, or any untoward clinical signs (including an abnormal laboratory finding) in subjects, users or other persons, whether or not related to the investigational medical device.

NOTE 1: This includes events related to the investigational medical device or comparator.

NOTE 2: This definition includes events related to the procedures involved (any procedure in the clinical investigation plan).

The study was not powered or designed as a study of diag. yield. Nor was this study designed to follow pts. with indeterminate cytology diagnoses. Non-malig. cytopathology. findings would require 6 mos. of follow-up (min. expect.) for a yield study.
