Disclosed is an NGT system, the system comprises a nasogastric tube having a diameter and length configured to pass through an esophagus such that the lumen of the NGT maintains fluid communication with a portion of the digestive tract, and a digestive tract sensor operatively associated with the NGT, the digestive tract sensor configured to sense from inside the body and transmit signals in response to one or both of conditions relating to nourishment states of the digestive tract, and positioning of the NGT.

Methods and apparatuses are disclosed for applying negative pressure to a wound site. In some embodiments, the apparatus comprises a source of negative pressure, a processing element, and a memory comprising instructions configured to, when executed on the processing element, cause the apparatus to attempt to generate, via the source of negative pressure, a desired negative pressure at the wound site. If the desired negative pressure has not been generated after a first predetermined period of time, the instructions cause the apparatus to: deactivate the source of negative pressure for a second predetermined period of time, and subsequently attempt to generate the desired negative pressure at the wound site.

A device configured to mechanically remove a fat phase from at least one adipose tissue includes a first pressing element and a second pressing element. Furthermore, a method for preparing a preparation including a fat-depleted adipose tissue, comprises mechanically removing a fat phase from at least one adipose tissue. In addition, there is provided a preparation including a fat-depleted adipose tissue, wherein the fat-depleted adipose tissue is prepared by mechanically removing a fat phase from at least one adipose tissue.

A wound therapy device and method includes a skin contacting element, a reactor, and a reactor housing element. The skin contacting element is configured for covering an associated tissue site, the reactor for creating a pressure condition at the associated tissue site upon actuation thereof, and the reactor housing element for accommodating the reactor. The skin contacting element has a skin contacting side and an interface side, which is opposite the skin contacting side. The reactor housing element has a lower affixing side and an upper side, which is opposite the lower affixing side.

A medical device comprises a catheter and an aspiration pump. The catheter has a hybrid reinforcement to improve performance characteristics. The aspiration pump is cycled to improve aspiration efficacy.

A system for reducing aerosols emitted from a patient on which a medical procedure is being performed. The system comprises a transparent dome and an adapter assembly configured to releasably support the dome. The system additionally comprises a support assembly configured to support the adapter assembly and the dome. The support assembly is adjustable such that the dome can be selectively positioned over an intended body area of the patient and block aerosols emitted from the intended body area.

A dressing for treating a tissue site may include a base layer, a sealing member, a first and a second wicking layer, and an absorbent layer. The base layer may have a plurality of apertures and may be adapted to cover the tissue site. The sealing member and the base layer may define an enclosure. The first and the second wicking layer may each be disposed in the enclosure with the absorbent layer positioned between the first and the second wicking layer. A conduit comprised of an absorbent material that is vapor permeable and liquid impermeable may be in fluid communication with the dressing for providing reduced pressure to the dressing. Other dressings, systems, and methods are disclosed.

A device and method for treating a wound of a patient with negative pressure is provided. The device comprises a heat-assisted pump system. The pump system can be powered in part by heat derived from the patient. The pump system may be configured to be highly planar, light weight, and portable. The pump system may comprise a Stirling engine or a thermal acoustic engine.

A method of adjusting a staple parameter of a surgical stapling instrument is disclosed. The method includes determining, by a control circuit of the surgical stapling instrument, a first stroke length for a first staple driver of the surgical stapling instrument to drive a first row of staples of a circular stapling head assembly of the surgical stapling instrument; detecting, by the control circuit, a malformed staple in the first row of staples; adjusting, by the control circuit, the staple parameter, based on the detection of the malformed staple; and determining, by the control circuit, a second stroke length for a second staple driver of the surgical stapling instrument to drive a second row of staples of the circular stapling head assembly.

An aspiration thrombectomy system is described with an aspiration catheter assembly having fittings interfaced with conduit and a pump. The aspiration catheter assembly can include a guide catheter and an aspiration catheter. The aspiration catheter can be introduced with a proximal end of a tubular element placed within the guide catheter to form a suction lumen extending through the aspiration catheter and a portion of the guide catheter. A connection section forming an effective seal between the aspiration catheter and the inner wall of the guide catheter can be fixed or extendable through actuation or release of a self-extending structure. The aspiration catheter can be positioned into an artery with a distal opening positioned proximal to a clot. The fittings can include a filter for removing thrombus from the aspiration flow. The fittings and/or the tubing adjacent the pump can include a flow meter for measuring flow to the pump. The fittings can include a pressure sensor for measuring pressure in the fittings. In addition, the aspiration catheter can have one or more pressure sensors integrated into the wall of the catheter with each configured to measure pressure in the interior or exterior of the catheter. The aspiration catheter and/or flow through the catheter can be manipulated based on pressure and flow measurements.
