Some devices for atraumatic retraction of tissue include a transcatheter deployable mesh hammock that is well-suited for laparoscopic, endoscopic, and robotic surgeries. Methods for atraumatic retraction of tissue include wrapping a mesh material around the tissue in a cradle-like fashion. In some embodiments, magnetic coupling of the proximal and distal ends of the mesh material can provide tissue containment and retractor securement to facilitate tissue retraction.

Laparoscopic retractor devices

This document provides systems and methods that can improve the efficacy of tube and needle thoracostomy. For example, this document provides devices and methods for confirming the proper placement of a chest tube or needle within the pleural space to relieve a pneumothorax or tension pneumothoax.

CO2-sensing chest tube and needle thoracostomy devices

Systems and methods that can improve the safety and efficacy of chest tube thoracostomy are described. For example, this document provides systems and methods that facilitate direct visual confirmation of the proper placement of a chest tube within the thoracic space.

Tube thoracostomy using an optical trocar

A system and method is provided for measuring a mechanical property of a biological tube. The system and method operate to arrange a plurality of piezoelectric elements about the biological tube and apply a predetermined force or transduce an endogeneous or exogeneous force to the biological tube. The system and method also operate to receive a respective signal from each piezoelectric element in the plurality of piezoelectric elements responsive to the application of the predetermined force or a transduced endogenous or exogeneous force and calculate the mechanical property of the biological tube based on the signals received from the plurality of piezoelectric elements.

Systems and methods for assessing properties of biological tubes

Systems and methods can be used improve the efficacy of tube thoracostomy. For example, this document provides devices and methods for confirming the proper placement of a chest tube within the pleural space.
