An implantable device for treating hypervolemia includes an expandable chamber, a rigid chamber coupled to the expandable chamber, a first valve in fluid communication with both the expandable chamber and the rigid chamber, a second valve in fluid communication with the rigid chamber and an exterior of the implantable device, and an osmotic fluid. The expandable chamber includes a first semipermeable membrane. The rigid chamber includes a piston. The first valve has an open position to permit fluid flow between the expandable chamber and the rigid chamber. The second valve has an open position to permit fluid flow from the rigid chamber to the exterior of the implantable device. The osmotic fluid has a higher osmotic concentration than bodily fluid. The osmotic fluid is designed to absorb water from the bodily fluid through the first semipermeable membrane.

This invention relates to apparatus used to alter the temperature and humidity of gases. The apparatus of the present invention comprises an insufflator, humidifier and transportation means connected to delivery means to deliver humidified and heated gases to a body cavity prior to and during a medical procedure. In one form of the present invention the insufflator and humidifier are contained in the one housing, while in another form the humidifier is located proximal and external to the insufflator. The transportation means that delivers the humidified gases to the body cavity comprises a flexible tubing having located within, throughout or around it heating means. The heating means may be a heat conductive wire, a ribbon of PTC material, or a conducting wire extruded into the walls of tubing, where the tubing may be made from a PTC material or flexible plastics.

A pharmaceutical composition for treating infertility in a female subject substantially consists of local anesthetic of amide type such as lidocaine, human albumin, viscosity controlling agent selected from recombinant hyaluronic acid and combination of recombinant hyaluronic acid and water-soluble cellulose ether, optionally citrate, glucose, and/or amino acid, water optionally comprising one or more ions selected from the group consisting of sodium, potassium, magnesium, calcium, acetate, chloride, sulfate. Also disclosed is a method of treating infertility by administration of the composition to a female subject in need thereof.

Systems and methods for performing Direct Sodium Removal (DSR) therapy are provided in which an implantable device includes a pump coupled to an inlet catheter designed for placement in a patient's peritoneal cavity, an outlet catheter designed to be coupled to the patient's bladder, and is operably coupled to an analyte sensor, the pump programmed to transfer and/or cease transfer of fluid from the patient's peritoneal cavity to the patient's bladder for voiding responsive to a level of analyte detected by the analyte sensor. In addition, the system may include a processor that computes an amount of analyte transferred per pumping session.

Systems and methods for pressure sensors being located in various components of a surgical medical gases delivery system (such as for laparoscopic surgery) are disclosed. The pressure sensors can enable gas supply (either of a surgical medical gases delivery system or supplementary to such a system) to sense pressure so as to safely insufflate the surgical cavity in a controlled manner. Advanced pressure sensing can also be provided to achieve specific flow algorithms and/or non-standard flow patterns that may help achieve functionality for mitigating smoke accumulation in the surgical cavity and/or impairment to vision, and helping to improve stability in the surgical cavity. The pressure sensing disclosed herein can allow for more control over the fundamental aspects of gas control and supply in the surgical gas delivery system, better performance, and outcomes of the surgery, and better incorporation of a humidification therapy.

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 flow of gas from and to the patient, based on a detected amount of smoke in the gas, while filtering particulate matter out of the gas and while maintaining an adequate moisture content in the gas. A controller may adjust the speed of a pump motor based on the detected amount of smoke, and may also open a suction exhaust path to vent gas and smoke if the amount of smoke detected exceeds a threshold.

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).

Methods of treating a medical condition in a patient include performing a lipectomy of visceral fat to remove a quantity of the visceral fat from the subject. The removal of visceral fat treats the medical condition such that the subject experiences at least a reduction of symptoms of the medical condition.

Various embodiments of a hydrophilic catheter introduction system for improved insertion of a shunt catheter are disclosed herein. The catheter introduction system includes an introducer sheath defining an inner surface that includes a hydrophilic coating to aid in passage of a catheter through the introducer sheath. Evaluation of the catheter introduction system with respect to other catheter introduction systems resulted in a significant decrease in average catheter threading time.

A container system configured to transfer heat to a fluid contained within the container system, such as dialysate. The container system may be configured to fluidly couple to a medical machine. The container system includes a flexible material comprising a wall of the container system. In examples, the flexible material defines a container volume configured to contain the fluid. The flexible material mechanically supports a circuit configured to generate and transfer heat to the fluid. The circuit is configured to flex and/or bend when the flexible material flexes and/or bends. In examples, the container system includes control circuitry configured to cause the circuit to generate heat based on a temperature of the fluid.
