Abstract: A medical instrument may include a tube, a sheath provided around and coaxial with the tube, and an inflatable balloon at a distal end of the sheath. The balloon may receive a fluid from a lumen of the sheath, and may have a central opening along a longitudinal axis thereof, and into which the tube extends, a proximal portion, a middle portion adjacent to and distal of the proximal portion, and a distal portion adjacent to and proximal of the middle portion. When the balloon is inflated with the fluid, a maximum diameter of the middle portion may be less than a maximum diameter of the proximal portion, and less than a maximum diameter of the distal portion. The medical instrument may also include an extraction member provided at a distal end of the tube, distal to the balloon, and movable axially relative to the balloon.

Abstract: Example medical devices, including example stents and stent systems, are disclosed. An example stent includes an expandable tubular scaffold having a proximal end and a distal end, a first wire coupled to the tubular scaffold, wherein the first wire is shaped into a first coil. The example stent also includes a sensor electrically coupled to the first wire, wherein the sensor is inductively powered by a magnetic field passing through the first wire.

Abstract: A stent formed of a radially-outwardly expandable material to exert a radially expansive force to inhibit migration. The stent includes a retention member configured to retain the stent in place relative to the body lumen in which the stent is placed. The retention member may further contribute to inhibiting migration of the stent and/or tissue at which the stent is deployed. Various features may be provided on the retention member to adapt the stent for use with a stoma and/or ostomy appliances or other particular locations in the body benefiting from the stent.
