  • Publication number: 20230338674
    Abstract: A device for delivering gas into a surgical cavity comprising a patient interface having an inlet, fluidly connected with a gas source, and an outlet, the patient interface being configured to deliver a conditioned flow of gas into the surgical cavity. The conditioned flow of gas may have the properties of having a reduced outlet velocity relative to the velocity of the inlet gas, or having a diffuse flow, or being heated, or being substantially laminar or non-turbulent, or a combination thereof. The invention may also comprise an attachment mechanism to attach to or anchor the patient interface.

  • Publication number: 20230105857
    Abstract: Disclosed herein is an obturator and/or cannula configured for insertion of a trocar assembly into a surgical cavity and allowing insertion of medical instruments into the surgical cavity through the cannula after removal of the obturator. The cannula can include an obturator for use in a trocar assembly. A trocar assembly is disclosed including a cannula having a shaft, optionally with a lumen, and one or more elements protruding outwardly from a surface of the lumen and an obturator. The obturator can comprise a shaft with one or more portions configured to accommodate the one or more elements protruding from the lumen surface when the obturator shaft is located in the lumen of the cannula.

  • Publication number: 20230082376
    Abstract: Disclosed herein is a cannula and/or medical instrument accessory configured for providing localized insufflation or venting of gases with respect to a surgical cavity of a patient (such as the pneumoperitoneum) and allowing insertion of medical instruments into the surgical cavity through the cannula. A medical instrument accessory such as a cannula and/or medical instrument accessory can be used for localizing insufflation or venting of gas or fluid near operating end of a medical instrument. The medical instrument accessory can comprise a body mountable over at least a portion of a medical instrument shaft, the body having an inner lumen, proximal end and distal end, the distal end comprising an opening, wherein the distal end is arranged in use at or adjacent an operating end of the medical instrument.

  • Publication number: 20220168512
    Abstract: 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.

  • Publication number: 20220080136
    Abstract: Filters for surgical procedures including a fluid pathway to transport fluid, such as smoke and/or gases, exhausted from a surgical site, a humidity regulating element located along the fluid pathway, and a filter element located downstream of the humidity regulating element such that the humidity regulating element and the filter element are in fluid communication with each other. The humidity regulating element is configured to remove or reduce humidity from the smoke and/or gases exhausted from the surgical site prior to the smoke and/or gases reaching the filter element. The filter element is configured to filter particulate matter from the smoke and/or gases exhausted from the surgical site.

  • Publication number: 20060291174
    Abstract: Using die side capacitors and embedded resistors, an advantageous power delivery network may be achieved. In some embodiments, the embedded resistors may be more precisely controllable. The number of die side capacitors may be reduced by combining embedded resistors with these capacitors to reduce costs. The embedded resistors may be provided within the metallization layers either at an upper layer or a lower layer, as two examples.

  • Patent number: 5121129
    Abstract: The EHF omnidirectional antenna system (10) includes a shaped lens (12) that is illuminated by a corrugated horn (14). The lens is disposed in the far-field of the horn and has two shaped surfaces (20 and 30) which together disperse the beam from the horn, such that a nearly uniform coverage over hemispherical coverage area is achieved at a frequency of approximately 44 GHz. The method of making the lens utilizes a surface shaping analysis to develop the shaped surfaces of the lens. A surface matching layer (44) is applied to all surfaces of the lens to reduce surface reflection.
