Sleeve with integrated insert

An extendable sleeve comprising:

• a cylindrical tube having a first opening at a proximal end, a second opening at a distal end, the distal end being opposite the proximal end, and a third opening through the cylindrical tube between the distal end and the proximal end;
• an insert affixed to the cylindrical tube around a perimeter of the third opening;
• and
• a releasable fastener coupled to the cylindrical tube proximate the third opening,
• wherein the extendable sleeve is in an extended state when the releasable fastener is unfastened, and
• wherein the extendable sleeve is in a retracted state when the releasable fastener is fastened.

A method of manufacturing a sleeve having an integrated insert, the method comprising:

• forming a third opening in a cylindrical tube having a first opening at a proximal end and a second opening at a distal end, the distal end being opposite of the proximal end, wherein the third opening is formed between the distal end and the proximal end, and wherein the third opening has a perimeter;
• affixing an insert to the cylindrical tube around the perimeter of the third opening;
• and
• affixing a releasable fastener to the cylindrical tube proximate the third opening, wherein the sleeve has a first length when the sleeve is in an extended state, wherein the sleeve has a second length when the sleeve is in a retracted state, and wherein the first length is longer than the second length.
