Abstract
Devices and methods allow surgical procedures to be performed on an organ without significant loss of fluid, such as, for example, surgical procedures on a beating heart. The devices include an expandable obstruction for insertion into the organ to block an opening in the tissue, and an access port with one or more conduits for accessing the interior of the organ.
Claims21
A device for preparing a heart for a surgical procedure, the device comprising:
- an access port comprising a hollow shaft having a distal end for insertion into the heart through an incision in the heart and a proximal end providing access to the hollow shaft after insertion into the heart;
- an obstruction, configured to be inserted into the heart through the access port;
- and
- a coring knife, assembled with the access port and configured to remove a core of heart tissue surrounding the access port to produce an opening in the heart,
- wherein the inserted obstruction is configured to occlude blood flow through the heart opening.
A device for preparing a heart for a surgical procedure, the device comprising:
- an access port comprising a hollow shaft having a distal end for insertion into the heart through an incision in the heart and a proximal end providing access to the hollow shaft after insertion into the heart;
- and
- an expandable obstruction, configured to be inserted into the heart through the access port and inflatable by supplying pressurized fluid through one or more conduits connected with the expandable obstruction, the one or more conduits extending from the proximal end of the hollow shaft,
- wherein the inserted and inflated expandable obstruction is configured to occlude blood flow through an opening in the heart.
A method for preparing a heart for a surgical procedure, comprising:
- creating a small incision in the heart;
- inserting an expandable obstruction into the heart through the incision;
- inflating the expandable obstruction;
- and
- removing a core of heart tissue surrounding the incision to produce an opening in the heart,
- wherein the inflated obstruction occludes blood flow through the opening, such that a surgical procedure may be performed on the heart while the heart is still beating.
A device for preparing the organ for a surgical procedure, the device comprising:
- an access port comprising a hollow shaft having a distal end for insertion into the organ through an incision in the organ and a proximal end providing access to the hollow shaft after insertion into the organ;
- an obstruction, configured to be inserted into the organ through the access port;
- and
- a coring knife, assembled with the access port and configured to remove a core of tissue surrounding the access port to produce an opening in the organ,
- wherein the inserted obstruction is configured to occlude fluid flow through the opening.
A method for preparing the organ for a surgical procedure, comprising:
- creating a small incision in the organ;
- inserting an expandable obstruction into the organ through the incision;
- inflating the expandable obstruction;
- and
- removing a core of tissue surrounding the incision to produce an opening in the organ,
- wherein the inflated obstruction occludes fluid flow through the opening, such that a surgical procedure may be performed on the organ without significant loss of fluid.
