Anchored guide tubes for insertion and stabilization of devices in body wall, systems, and methods

A medical device, comprising:

• a tube, comprising:
• a proximal end,
• a distal end,
• a lateral wall extending from the proximal end to the distal end of the tube, the lateral wall having an inside surface surrounding a hollow interior of the tube,
• an engagement feature on the lateral wall, and
• a port proximate the proximal end;
• an inflatable member located at a distal end portion of the tube;
• a fluid passage fluidically coupling the port and the inflatable member, wherein the fluid passage extends longitudinally within a recessed channel formed in and extending longitudinally along the inside surface of the lateral wall, wherein the recessed channel is open along a side of the channel facing the hollow interior;
• and
• a repositionable anchor located on the tube proximal to the inflatable member and configured to selectively engage the engagement feature;
• wherein 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;
• and
• wherein the recessed channel is a first recessed channel and the medical device further comprises a second recessed channel formed in and extending longitudinally along the inside surface, wherein the first recessed channel is within the second recessed channel.
