End-to-Side Anastomosis Anastomoses are the connections that join arteries together to create a bypass. The Greek roots of the word translate to “furnish with a mouth,” which in this case means creating an outlet in one tube that connects with an opening in another tube to form a branching network.
Apparatus and methods are provided for forming a working space on the interior wall of a blood vessel, such as the aorta. The working space is isolated from blood flow and permits creation of an anastomotic hole and subsequent suturing of the hole to form an end-to-side anastomosis, even while the heart is beating. The apparatus comprises tools including inflatable barriers, such as cup-shaped balloons, which engage the inner wall of the blood vessel with minimum trauma and maximum sealing. In a first embodiment, the inflatable barrier is introduced through a penetration at the site of the anastomotic attachment. In a second embodiment, the inflatable barrier is introduced through a second penetration axially spaced-apart from the site of the anastomotic attachment.
A vascular clip for use in end-to-side anastomoses having a handle connected to a lower ring and an upper ring. The handle includes a resilient element biasing the two rings together so that the rings are closely juxtaposed when the clip is closed. The respective facing surfaces of each of the rings may be provided with a rough surface. A graft vessel or an artificial aneurysm may be sutured to the lower ring. The graft vessel or artificial aneurysm may be autologous or heterologous material or may be made of synthetic material. The handle may fit into a clip applier that facilitates the application of the clip. The handle and the clip applier may be of different shapes depending on the various applications of the clip. The rings may also have different shapes and sizes to accommodate different kinds of anastomoses and different vessels of all sizes in all parts and cavities of the human or animal body. The two rings are substantially the same dimension, which preferably may be in the range of from around 2 mm up to around 2.5 cm.
