Device, system, and method to secure an article to a tissue
A device for securing an article to a tissue may include a body, transitionable from a deployment state to a securing state, having a first portion, a second portion, and a medial portion therebetween. The first portion and the second portion may each have an end configured to pierce the tissue. The device in the deployment state may have a linearly extended or a U-shaped structure. In the securing state, the first portion may be embedded in the tissue and the medial portion may contact the article. A system for securing the article to the tissue may releasably engage the device while in the deployment state. A method for securing the article may include contacting the article with a tissue surface and releasing the device from the system so that the device, in the securing state, may anchor the article to the tissue.
1. A system for securing an article to a tissue by releasably engaging at least one securing device, the system comprising: an exterior tube comprising an interior tube and a distal end, wherein a substantial portion of the distal end is configured to contact the tissue; a push rod at least partially disposed within the interior tube; and at least one securing device comprising a tab standoff that is disposed between a first end configured to pierce the tissue and a second end, wherein the first end and the second end are each transitionable from a first deployment state to a second securing state, wherein a body of the at least one securing device comprises a first portion, a second portion, and a medial portion between the first portion and the second portion, wherein the tab standoff is in mechanical communication with the medial portion of the body at a first end of the tab standoff and a tab at a second end of the tab standoff, wherein the tab is displaced by a slot from the body, and wherein the push rod is configured to: engage the tab standoff, and cause the first end of the at least one securing device to pierce the tissue and transition from the first deployment state to the second securing state, wherein the interior tube is movable relative to the exterior tube, and wherein the interior tube is configured to release the second end of the at least one securing device when withdrawn into the exterior tube, thereby causing the second end of the at least one securing device to transition from the first deployment state to the second securing state.
2. The system of claim 1 , wherein the exterior tube comprises one or more of a metal and a plastic.
3. The system of claim 1 , wherein the push rod comprises a metal.
4. The system of claim 1 , wherein the exterior tube has a diameter of 3 mm to 8 mm.
5. The system of claim 1 , wherein the exterior tube comprises a pawl having a surface geometry complementary to a geometry of at least a portion of an external surface of the article.
6. The system of claim 5 , wherein the pawl is configured to form a stable mechanical contact between the article and the tissue by contacting at least a portion of the external surface of the article.
7. The system of claim 1 , further comprising:
a medial tube disposed at least partially within the exterior tube;
wherein the interior tube is at least partially disposed within the medial tube.
