Medical Device

A medical device that promotes adhesion between biological tissue, the medical device comprising:

• an adhesion promotion sheet made of a biodegradable sheet that promotes adhesion of the biological tissue, the adhesion promotion sheet including a first region having a plurality of through-holes that pass through the first region and a second region provided outside the first region in a plane direction;
• a pulling unit connected to the adhesion promotion sheet and configured to deform the second region so as to cover at least a portion of an outer peripheral surface of a biological organ to be joined with a pulling operation;
• and
• wherein the pulling unit includes a connection section connected to the second region and a non-connection section, the non-connection section is not connected to the second region and is configured to be pulled out of the adhesion promotion sheet.

A method of promoting adhesion between biological tissue comprising:

• disposing a medical device at one joint target site, the medical device comprising an adhesion promotion sheet including a first region that promotes adhesion of biological tissues and a second region provided outside the first region in a plane direction, and a pulling unit connected to the adhesion promotion sheet;
• pulling the pulling unit to deform the adhesion promotion sheet of the medical device to deform the second region;
• fixing the adhesion promotion sheet of the medical device to the one joint target site;
• and
• joining the one joint target site and an other joint target site in a state where at least a portion of the adhesion promotion sheet is disposed between the one joint target site and the other joint target site.
