Tissue fixation

A method for fixating tendon tissue, the method comprising:

• providing a fixation device comprising a carrier member formed to exhibit a first elasticity, the carrier member having a first part, a second part, and a junction therebetween, the fixation device including multiple interconnecting struts extending in a crisscross pattern from intersection points to define a multi-cellular structure such that each of the struts and intersection points are monolithically formed relative to each other,
• wherein the fixation device further comprises one or more first attachment members protruding at a first angle from the first part toward the junction, the one or more first attachment members configured to engage a first portion of the tendon tissue for attaching the first part to the first portion,
• wherein the fixation device further comprises one or more second attachment members protruding from the second part, the one or more second attachment members configured to engage a second portion of the tendon tissue for attaching the second part to the second portion,
• wherein the carrier member is configured to conform into a cylindrical structure such that a first opening is formed at the first part, a second opening is formed at the second part, the junction is disposed between the first opening and the second opening, the one or more first attachment members protruding and monolithically extending from the intersection points of the first part in an interior of the cylindrical structure, and the one or more second attachment members protruding and monolithically extending from the intersection points of the second part in the interior of the cylindrical structure;
• wherein the one or more first attachment members and the one or more second attachment members are formed to exhibit a second elasticity, the second elasticity being less than the first elasticity;
• advancing, when the carrier member is conformed into the cylindrical structure, the first portion through the first opening into the interior of the cylindrical structure until a tip of the first portion reaches the junction such that the one or more first attachment members engage the first portion;
• and
• advancing, when the carrier member is conformed into the cylindrical structure, the second portion through the second opening into the interior of the cylindrical structure until a tip of the second portion reaches the junction such that the one or more second attachment members engage the second portion,
• wherein, when the first part is attached to the first portion and the second part is attached to the second portion, the first portion and the second portion are limited in being pulled apart from one another during physiological use of the tendon tissue.
