Tissue retraction device and delivery system

A tissue retraction device, comprising:

• a first tissue clip coupled to an elastic member by a first coupling assembly, and a second tissue clip coupled to the elastic member by a second coupling assembly, and wherein the first and second coupling assemblies each include:
• a coupler body having a first end region;
• and
• a compression member;
• wherein the first end region of each of the coupler bodies is configured to extend into a portion of the lumen of the elastic member;
• wherein each of the compression members are designed to compress the elastic member onto each of the coupler bodies such that the elastic member is fixedly engaged to each of the coupler bodies.

A method of dissecting tissue, the method comprising:

• advancing a tissue retraction device to a target site, the tissue retraction device including:
• a first tissue engagement member coupled to an elastic member by a coupling assembly, the coupling assembly including:
• a first coupler body having a first end region;
• and
• a first compression member;
• wherein the first end region of the first coupler body is configured to extend into a portion of a lumen of the elastic member;
• wherein the compression member is designed to compress the elastic member onto the first coupler body such that the elastic member is fixedly engaged with the coupler body;
• manipulating the first tissue engagement member between a first configuration and a second open configuration;
• and
• attaching the first tissue engagement member to the target site.
