Electrohydraulic lithotripters comprising a plurality of electrohydraulic probes are disclosed. Each probe of the plurality of probes comprise a first electrode and a second electrode positioned at a distal end of the probe such that when the probe is discharged, an electric arc between the first electrode and the second electrode produces a shockwave that radiates from the distal end of the probe. A first probe and a second probe of the plurality of probes may be configured to discharge simultaneously or sequentially.

Unfocused electrohydraulic lithotripter

A medical device accessory comprising an interface configured to connect the medical device accessory with a medical device for administration of a medical treatment using the medical device and the medical device accessory, a plurality of electrical contacts proximate the interface, the electrical contacts comprising a lead electrical contact adapted to receive an voltage from a power source associated with the medical device and one or more identifying electrical contacts, and at least one conductor providing an electrical connection between the lead electrical contact and the one or more identifying electrical contacts. An arrangement of the one or more identifying electrical contacts connected to the lead electrical contact identifies a characteristic of the medical device accessory.

System for identifying the presence and correctness of a medical device accessory

A lithotripter tip configured for use within an invasive lithotripter probe may include a lithotripter tip body dimensioned and configured to be threaded through a human vein or artery of a patient and delivered to a position directly adjacent to a concretion within the patient. The lithotripter tip body may define an interior region in communication with an aperture at a distal end of the lithotripter tip body and the lithotripter tip body may define at least one port in communication with the interior region that is configured to receive a liquid and provide a path for the liquid to flow into the interior region of the body. A first electrode and a second electrode are positioned within the interior region of the lithotripter tip such that such that when liquid from the at least one port is within the interior region and an electric arc occurs between the ends of the first and second electrodes, a gaseous bubble forms within the interior region and a resulting shockwave travels out of the aperture at the distal end of the lithotripter tip body and impacts the concretion positioned directly adjacent to the lithotripter tip body.

Gas recirculation systems for use in endoscopic surgical procedures including a gas recirculation pump are disclosed. The gas recirculation pump may work in conjunction with an insufflator used to inflate a patient's peritoneal cavity during surgery. The gas recirculation system may recirculate a high flow rate of gas from and to the patient while filtering particulate matter out of the gas and while maintaining an adequate moisture content in the gas. The gas recirculation pump may include a disposable pump cartridge releasably connected to a pump motor. A controller may detect a fault or safety condition in the gas recirculation system based on the load placed on the pump motor.

Gas recirculation system and method

An invasive electrohydraulic lithotripter probe may comprise a lithotripter tip that comprises a first electrode and a second electrode. The lithotripter tip has a length in excess of 250 cm and is dimensioned to be inserted into a long channel having a length in excess of 250 cm. The lithotripter probe may include a material that reinforces a linear strength of at least a portion of the lithotripter probe.

Radially-firing electrohydraulic lithotripsy probe

Handheld carboxy therapy applicators are disclosed. In one implementation, a handheld carboxy therapy applicator includes a heater module, a humidification module, and a hypodermic needle. The heater module is configured to receive a flow of gas and to warm gas within the flow of gas. The humidification module is in fluid communication, such as in a serial connection, with the heater module. The humidification module is configured to receive the flow of gas from the heater module and to humidify the gas within the flow of gas. The hypodermic needle is in serial connection with the humidification module. The hypodermic needle is configured to receive the flow of gas from the humidification module and to inject the flow of gas into a tissue of a patient.

A lithotripter tip configured for use within an invasive lithotripter probe may include a lithotripter tip body defining an interior region in communication with an aperture at a distal end of the lithotripter tip body and defining at least one port in communication with the interior region. A first electrode and a second electrode are positioned within the interior region of the lithotripter tip such that such that when liquid is within the interior region and an electric arc occurs between the first and second electrodes, a gaseous bubble forms within the interior region and a resulting shockwave travels out of the aperture at the distal end of the lithotripter tip body.

Insufflation systems including a plurality of flow rate sensors are disclosed. Each flow rate sensor is configured to measure flow across a different flow rate range, with the combined flow rate ranges of the sensors encompassing the entire flow rate capability of the insufflation system. A controller selects the most appropriate flow rate sensor based on the gas flow required to be delivered to the patient.

High resolution system and method for controlling high and low insufflation flow rates

A high-flow luer lock connector is disclosed. A high-flow luer lock connector comprises a connector body defining an interior region, a lumen, and an extended passageway. The interior region is bounded by a cylindrical side wall and a base wall. The lumen is defined at the base wall of the interior region and extends no more than 0.274 of an inch into the interior region. The extended passageway comprises a first and second end and passes through the connector body and the lumen. The extended passageway is in communication with the interior region to allow insufflation gas to flow through the interior region and extended passageway.
