One aspect of the invention provides a trocar including: a central cylinder defining a central channel and having a distal end adapted and configured for insertion within a subject; one or more gas outlets located within the central cylinder proximate to the distal end of the trocar; and one or more liquid outlets located within the central cylinder on a proximal side of the one or more gas outlets. The one or more liquid outlets are adapted and configured to dispense a liquid when an endoscope is withdrawn from a fully extended position within the central channel of the trocar to a position proximate to the one or more liquid outlets. Distal advancement of the endoscope to a position adjacent to the one or more gas outlets removes liquid from a distal end of the endoscope.

A method of operating a manipulator arm comprising a manipulator interface configured to removably couple with and transmit actuation force to a medical instrument includes mounting a cannula to a cannula mount coupled to the manipulator arm; mounting a medical instrument to the manipulator interface; inserting a shaft of the medical instrument through an entry guide mounted to the cannula; rotating the manipulator interface and the medical instrument relative to the cannula mount; and rotating the entry guide relative to the cannula mount about a longitudinal axis of the cannula.

This invention provides for a component forming a part of a breathing tube, or forming the breathing tube, for example as a part of a breathing circuit for respiratory therapy. The component comprising a tubular body having a foamed wall. The foamed wall can be formed from extrusion of a single extrudate. The foamed wall is of a sufficient minimum optical transparency such that, in use, there is enabled the visual detection of a liquid (or condensate that may have formed) within the tubular body.

Method for detecting leaks and/or verifying adequate closure following a medical procedure, on a hollow or tubular organ of a subject, wherein a leak test is performed by injecting or insufflating, in the concerned organ, a specific test gas which is not commonly produced or naturally present within the body of the subject, or which is present or produced in a precisely known amount or concentration, and by analyzing percutaneously the gas or gas mixture present locally within the body cavity in which the organ is situated, and then verifying the presence, and preferably determining the concentration, of the injected or insufflated test gas in the local gas or gas mixture of the body cavity and indicating whether the concerned organ or a lumen defined by the latter is leak-free or not.

The presently disclosed embodiments relate to insufflation and irrigation conduits for vessel harvesting systems and methods of their use. In particular, the present disclosure relates to a system having a combined cabling for providing gases, liquids, and/or electrical power to an attached medical device and method of use.

The invention relates to a method for determining compliance of a cavity in minimally invasive surgery and to devices for carrying out said method.

A placement device is provided for causing a catheter to be placed inside of a body. The placement device includes an insertion unit, a transmission unit and a supply member. The supply member includes a supply unit main body, and a projection. A through-hole is formed on the inner peripheral surface of the supply unit main body at a position closer to a distal end side of the supply portion main body than the projection, and the through-hole communicates with an inside of the supply unit main body at the distal end side of the supply unit main body.

An implantable tissue connector comprises a conduit and at least one bulge extending outwardly from the conduit's outer surface in a circumferential direction. At least one blocking ring loosely fitting over the outer surface with a clearance between the outer surface and the blocking ring is provided for mounting tubular living tissue within the clearance. The blocking ring has an inner diameter which is sized relative to an outer diameter of the bulge to prevent the blocking ring from slipping over the bulge when living tissue is mounted within the clearance. During implantation, the conduit is inserted into the tubular part of living tissue and over the bulge. Then, the blocking ring is pushed over the free end of the living tissue against the bulge. The living tissue is secured to the conduit with a self-enhancing effect when the tissue tends to be pulled off of the conduit.

An aerosol generator is positioned adjacent to a patient as an attachment to a trocar. The trocar has an entry port for insufflation gas. Aerosol generated by a vibrating element is entrained in the insufflation gas and the mixture is delivered through the trocar. The aerosol may contain a medicament. The trocar may be a conventional trocar. Such trocars are typically used for a camera. The delivery of the aerosolized medicament can occur at the start of the procedure and be delivered in bolus. At the start of the procedure, the peritoneum is being inflated by means of the flow of insufflator gas. This gas flow will help to entrain the aerosolized medicament to the pneumoperitoneum regions. The surgeon can temporarily remove the camera from the trocar port to facilitate insertion and positioning of the aerosolizing unit.

The present invention relates to an ultrasonic aerosolization platform that has a single access port (10) provided with a trocar (11) inserted into the surgical cavity through a single incision and provided with at least one internal channel (101) in which is positioned an ultrasonic aerosolizer (20) provided with a head (21) that houses a power piezoelectric transducer (214) and a resonating rod (22) that extends orthogonally from the head (21), provided with an internal channel (221) in communication with the internal channel (212) of the head (21) and a free end (222) with an atomization nozzle (30) with orifices (31); a high-frequency ultrasound generator (40) that provides an electrical signal to the power piezoelectric transducer (214), which converts said electrical signal into mechanical oscillations transmitted to the resonating rod (22) in the form of mechanical standing waves; and a processing unit (50) provided with an interface (60) for adjusting the excitation frequency of the transducer (214), adjusting the flow of the therapeutic substance, and adjusting the operating and actuation time of the electrode (not shown) arranged in the resonating rod (22).
