A compressed gas motor. The motor has a port and a hollow cylinder delimited by a wall with a ventilation opening, a rear closure, and a plunger axially movable in the cylinder. The plunger divides the cylinder into front and back chambers. The ventilation opening is periodically opened towards the back chamber during operation of the motor by movement of the plunger. A compression spring in the front chamber urges the plunger towards the rear closure and/or a tension spring in the back chamber draws the plunger towards the rear closure so that the back chamber is closed relative to the ventilation opening by the plunger and the back chamber is connected with the port when the same pressure prevails in the front and back chambers. The motor can be used in surgical drive systems, medical lavage systems and medical devices. Also disclosed is a method for operating the motor.

A piston is inserted at one end of the water inlet chamber, the piston and an interior of the water inlet chamber form a chamber, a recess is formed on a side of the piston away from the chamber, a rotor is rotatably connected in the recess, the rotor is connected with a link, an end of the link away from the rotor is connected with an eccentric rotating assembly, one end of the water inlet assembly communicates with the water reservoir, a check valve is arranged in the water inlet assembly, and another check valve is arranged in the water outlet assembly.

A nozzle and an ear cleaning device are disclosed. The nozzle includes: a main body, where the main body is provided with a first hole portion penetrating in a front-rear direction; and a housing, where the housing is connected to the main body and surrounding a periphery of the main body, the housing is provided with a guide portion and a plurality of drainage portions, the guide portion has an outer diameter gradually increasing from a front end of the main body to a rear end of the main body, the plurality of drainage portions are arranged at intervals in a circumferential direction of the housing, and each of the drainage portions is communicated with the front end of the main body and extends from the front end of the main body toward the rear end of the main body.

Briefly summarized, embodiments disclosed herein are directed to apparatus and methods for removing an occlusion from an indwelling catheter. The system can include a pressurized fluid conduit for delivering pressurized fluid to an occlusion site, and ablating the occlusion. A negative pressure source in fluid communication with the catheter lumen can then aspirate the occlusion. The positive pressure source can provide a pulsed pressurized fluid to facilitate ablation. The system can also include tip tracking and tip location systems to ensure the pressurized fluid conduit does not extend beyond the catheter lumen, causing damage to the vasculature. The system can further include an ultrasound transducer, coupled with one of the catheter and the pressurized fluid conduit to provide ultrasonic wave energy to the occlusion to further facilitate ablation thereof.

The invention relates to an ear catheter for insertion into the eustachian tube with a first tube as catheter tube (3) provided with at least one first lumen as injection duct (3A) for the application of a liquid/fluid, at least one second lumen as pressure relief lumen (3B) for pressure relief and a self-expandable sealing element (2) for the occlusion of the eustachian tube, as well as an insertion aid comprising a headpiece, a middle piece and an end piece, wherein the insertion aid consists of a biocompatible polymer, and with at least one separator line extending at least through each of the middle piece and the end piece, along which the insertion aid can be unfolded or split open. The insertion aid proposed by the invention can thus be removed from a catheter even if the catheter ends are blocked.

A method and apparatus for injecting a saline solution into an open cavity of a patient's body, and, alternatively, vacuuming fluids from the open cavity during laparoscopic surgery that provides constant feed and amplified pressure to provide a steady fluid output, in a disposable, single use handheld surgical device.

A device for removing obstructive material from a patient may include an elongate rotational member having a distal end and a proximal end, an internal irrigation catheter at least partially surrounding the rotational member, and an aspiration catheter at least partially surrounding the rotational member and the irrigation catheter. The distal portion of the rotational member is configured to change compliance of the obstructive material and facilitate obstructive material aspiration outside the patient.

A process for recovering one or more blastocysts from a uterus of a human includes a step of placing a device transvaginally into a cervical canal of the patient; a step of delivering fluid through the device to the uterus and applying a vacuum to a uterus of the patient to aspirate fluid and entrained one or more blastocysts from the uterus; and a step of performing a biopsy procedure on the one or more recovered blastocysts to remove one or more of trophectoderm cells or inner cell mass from the recovered blastocysts. The process may further include a step of storing one or more of the biopsied trophectoderm cells or inner cell mass following the biopsy procedure and a step of performing at least one molecular diagnostic assay test on the one or more of the biopsied trophectoderm cells or inner cell mass.

Systems and methods for automated assessment and monitoring of bodily fluids are disclosed. In one embodiment, a system for provisioning a treatment composition to a bladder of a patient includes: an irrigation bag that carries the treatment composition; a catheter configured for connecting the irrigation bag to the bladder; a flow regulator configured for controlling a flow of the treatment composition from the irrigation bag to the bladder; and a drainage bag in fluid communication with the bladder through a drainage tubing of the catheter. The drainage tubing is configured for draining urine from the bladder. The system also includes: a first sensor for detecting a first amount of the treatment composition in the irrigation bag; a second sensor for detecting a second amount of urine in the drainage bag; a third sensor for detecting a concentration of particles in the urine carried by the drainage bag; and a controller.
