SP Thoracic IDE Study

To confirm the safety and performance of the da Vinci SP Surgical System, Instruments and Accessories in pulmonary lobectomy, and in thymectomy procedures.

Primary performance:

The primary endpoint will be assessed as the ability to complete the planned da Vinci SP-assisted thoracic procedure without conversion to an alternate approach. Conversion to an alternate approach comprises undocking of the da Vinci SP to complete the planned procedures using other methods, such as open, VATS, or multiport robotic (da Vinci SI or X/Xi)

Primary Safety:

The primary safety endpoint will be assessed as the incidence of all intra-operative and post-operative adverse events that occur through the 30-day follow-up period.

Eligibility Criteria:
Inclusion Criteria:

* Age \> 21 years
* BMI ≤ 35
* ASA ≤ 3
* Willing and able to provide a written informed consent
* Willing and able to comply with the study protocol requirements including follow-up examinations at 14 days and 30 days post-operatively, and post-market long term follow-up on an annual basis through 5 years

Lobectomy Inclusion Criteria:

- Clinical stage I or II primary lung cancer or other suspected lung malignancy; or benign lung disease requiring resection; primary tumor ≤ 5cm diameter

Thymectomy Inclusion Criteria:

- Masaoka clinical stage I or II thymoma; or thymectomy for myasthenia gravis; thymic mass ≤ 5 cm diameter

Exclusion Criteria:

* Clinical or radiological evidence of mediastinal or systemic metastatic disease
* Life expectancy \< 6 months
* Subject with a known bleeding or clotting disorder

* History of pulmonary hypertension
* Previous ipsilateral thoracic surgery or radiotherapy

Thymectomy Exclusion Criteria:

* Uncontrolled myasthenia gravis symptoms at the time of scheduled surgery
* Tumor requiring resection of local structures (except pericardium)
* Confirmed thymic carcinoma

Intraoperative Exclusion Criteria:

- Anatomy determined intra-operatively to be unsuitable for minimally invasive surgery
