Abstract
Improved anastomosis devices having structural upgrades to increase ease of use while simultaneously increasing patent safety. The anastomosis device can include an introducer member having an introducer rod and an introducer cap to provide additional support to a catheter portion of the anastomosis device such that damage associated with installation of the catheter, deployment of tissue approximating structures and/or removal of the catheter can be minimized. The anastomosis device can further include a valve cap designed to constrain and reinforce a thin-walled section of a proximal funnel portion of the anastomosis device such that ballooning of the thin-walled section under the influence of a pressurized inflation fluid can be avoided during inflation as well as a time of tissue approximation and tissue healing.
