  • Publication number: 20220401125
    Abstract: Disclosed are medical devices for surgical procedures, especially procedures that involve the manipulation of surgical instrument end effectors close to the skin surface at an incision site. In accordance with some embodiments, an instrument access device is configured to couple to a wound retractor at a distal end of the device and to receive a multiple instrument entry guide in a port at the proximal end of the instrument access device, with an envelope between the distal and proximal ends defining a sealed cavity for maintaining insufflation pressure. Various embodiments provide means for rotating an assistant port in the envelope about a port that receives the instrument entry guide without twisting the envelope. Also disclosed are various envelope shapes. Also disclosed is an instrument entry guide that aligns surgical instrument shafts.

  • Publication number: 20220008100
    Abstract: A cannula includes a tube having a central passage extending between a proximal end and a distal end of the tube along a longitudinal axis of the tube. A first cross section of the passage taken at or adjacent the distal end of the tube and in a plane normal to the longitudinal axis has a first cross-sectional shape, the first cross-sectional shape being non-circular. A second cross section of the passage taken through a portion of the tube proximal to the distal end of the tube and in a plane normal to the longitudinal axis has a second cross-sectional shape. The first cross-sectional shape is different from the second cross-sectional shape. Systems related to cannulas and tools for insertion through cannulas.

  • Publication number: 20210315609
    Abstract: A medical device includes a tube comprising a proximal end, a distal end, a wall extending from the proximal end to the distal end of the tube and surrounding a hollow interior of the tube, and one or more engagement features on the lateral wall. An inflatable member is located at a distal end portion of the tube. The medical device also includes a repositionable anchor located on the tube proximal to the inflatable anchor and configured to engage the one or more features on the lateral wall. In a first configuration of the medical device, the repositionable anchor is translatable along the tube, and in a second configuration of the medical device the repositionable anchor is fixed in translation relative to the tube.
