Endoscopic vessel harvesting devices with conditioning of insufflation gas

A vessel harvesting apparatus for removing a blood vessel from a patient includes collection and conditioning (i.e., treatment) of expelled insufflation gas prior to releasing the gas into the air of the operating room. An endoscopic instrument has a distal end with a vessel harvesting tip and has a proximal end with a handle. An insufflation channel is configured to convey an insufflation gas subcutaneously into a dissected space within the patient. A removal channel is configured to evacuate fluidic contents from the dissected space, wherein the fluidic contents include insufflation gas and biological impurities. A processor/separator is coupled to the removal channel to process the fluidic contents to retain at least some of the biological impurities and to exhaust the insufflation gas.

Antiseptic applicator

An applicator assembly includes at least one ampoule formed of a frangible material and containing liquid to be applied, a body having a proximal end, a distal end, and an interior portion defining a chamber adapted to receive the at least one ampoule, an application member attached to the distal end of the body, an actuator projecting from the body operable to fracture the at least one ampoule, a trench formed in a surface of the body, and a vent disposed through a surface of the trench.

GAS TREATMENT DELIVERY SYSTEMS AND METHODS
20190351125 · 2019-11-21 ·

The present disclosure provides apparatuses and systems for delivering a measureable absorbed-dose of a gaseous activating agent to a fluid including a biological liquid and/or cells. The apparatuses or systems include a gas-fluid contact device configured to controllably rotate or oscillate a control member having an interior surface in contact with the fluid and a control system configured to control rotation or oscillation of the contact member by the gas-fluid contact device. In some embodiments, the control system is further configured to control absorption of the gaseous activating agent by the fluid. The present disclosure also provides methods of treating a fluid including a biological liquid or cells with a gaseous activating agent to controllably activate the fluid.

Method for reducing or removing biofilm
10470789 · 2019-11-12 · ·

A method for reducing or removing biofilm on a target tissue or prosthesis surface includes providing a coupling space or antechamber between the operative tip or end of an ultrasonic probe and a target treatment surface, the space or antechamber being fillable with a liquid irrigant to transmit ultrasonic vibration and facilitate extraction of biofilm fragments including potentially pathogenic particles. A second phase of treatment in the case of organic tissue involves the attachment of one or more ultrasonic transducers to a patient over or near a surgical treatment site after surgery is terminated. Each applied ultrasonic transducer is used to vibrate the patient's tissues at the treatment site to disrupt biofilm formation.

Method for continuous virus inactivation

The invention provides a method for continuous virus inactivation. The product stream is segmented by introducing a separating medium which is immiscible with the product stream and the segmented product stream is transported into a reactor 1 as detention segment under virus-inactivating conditions for the required detention time.

Door latch, lock and open mechanism for medical device treatment system

A latch and lock assembly includes a lever pivotable between a latched and unlatched position. A first actuator selectively moves a locking tab between a locked and unlocked position. In the locked position, the locking tab blocks pivotable movement of the lever from the latched position to the unlatched position. In the unlocked position, the locking tab allows pivotable movement of the lever from the latched position to the unlatched position. A second actuator selectively rotates a door opening tab between a first and second position when the locking tab is in the unlocked position is included. When the door opening tab is in the first position the lever is in a latched position, and when the door opening tab is rotated from the first position to the second position, the door opening tab abuts the lever and urges the lever from the latched position to the unlatched position.

Skin Disinfectant Wipe
20240189562 · 2024-06-13 ·

A skin preparation device for applying an antiseptic composition to skin of a patient that includes an applicator configured to absorb the antiseptic composition, the applicator comprising a top surface and a bottom surface, the bottom surface configured to apply the antiseptic composition to the skin of the patient, and a gripping portion configured to provide a portion of the skin preparation device that is gripped by a user when using the skin preparation device.
