Intended Use

The EndoWrist Mercury Bipolar Grasper is intended to be used with compatible systems for endoscopic manipulation of tissue, including dissection, grasping, retraction, and bipolar coagulation of tissue.

Device Story

EndoWrist Mercury Bipolar Grasper is a multiple-use, electrosurgical endoscopic instrument for use with da Vinci Xi (IS4000) and da Vinci X (IS4200) surgical systems and an external electrosurgical unit (ESU). Device comprises housing, shaft, wrist, and grasping tip. Operates via robotic control to interact with patient tissue; allows user to select between two grip strength modes (DEFAULT and STRONG). Used by surgeons in operating rooms to perform tissue grasping, dissection, retraction, and bipolar coagulation. Provides enhanced control and grip force options compared to previous iterations, facilitating precise tissue manipulation during minimally invasive procedures.

Clinical Evidence

No clinical data. Evidence consists of bench testing (physical, mechanical, electrical, user interface, and software verification) and design validation using animal and cadaver models to confirm functional performance and compatibility with da Vinci surgical systems.

Technological Characteristics

Multiple-use electrosurgical endoscopic instrument; consists of housing, shaft, wrist, and grasping tip. Features two selectable grip strength modes (DEFAULT and STRONG). Compatible with da Vinci Xi (IS4000) and da Vinci X (IS4200) systems and external ESU. Robotic-controlled articulation.

Indications for Use

Indicated for adult and pediatric patients undergoing urologic, general laparoscopic, gynecologic laparoscopic, general thoracoscopic, and thoracoscopically-assisted cardiotomy procedures, including coronary anastomosis via adjunctive mediastinotomy. Used by trained physicians in operating room environments.

Dear Mr. Kanani:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/ofdocs/ofpmn.cfm identifies combination product submissions. 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.
