  • SENSING CANNULA SYSTEMS
    Publication number: 20230149620
    Abstract: Disclosed cannula systems can detect the tissue type within which the cannula tip is located in real time using electrodes adjacent the cannula tip. The sensing cannula system can differentiate when the cannula tip is in adipose tissue or muscle based on electrical impedance. The system can be used in fat grafting and liposuction procedures, for example. An operator can detect if the cannula tip enters muscle by watching for an indicator light or audible alarm that is automatically activated by the device based on a change in sensed impedance. The device may also stop the flow of fat through a pump halting injection into the sub-muscular space.
    Type: Application

  • TRANSITION TO TRANSLUCENT SUTURES
    Publication number: 20210308319
    Abstract: An absorbable medical article comprising: an absorbable polymeric substrate; and an absorbable composition disposed on at least a portion of a surface of the substrate, wherein the absorbable composition comprises: (i) at least one absorbable coating polymer distinct from the substrate and (ii) a colorant that is miscible with the absorbable coating polymer.
