Abstract:

A system and method for closing a first side of a severed bone with a second side of a severed bone of a patient. The system includes a first anchor mechanism which is adapted to enter into the first side of the bone and a second anchor mechanism which is adapted to anchor into the second side of the bone. The second anchor mechanism is separate and remote from the first anchor mechanism. The system also includes a lash that extends through the first and second anchor mechanisms and which binds the first side of the severed bone with the second side of the severed bone. Preferably, the lash comprises a wire made of stainless steel or suture material. A method for closing a first side of a severed bone with a second side of a severed bone. The method includes the steps of anchoring a first anchor mechanism into the first side of the severed bone, anchoring a second anchor mechanism into a second side of the severed bone, extending a lash through a first opening of a housing of the first anchor mechanism in the first side, extending the lash through a second opening of a housing of the second anchor mechanism, pulling the lash until the first side and second side are contacting each other, and fixing the lash so the first side and second side maintain contact with each other.

Abstract:

An apparatus for treating a patient. The apparatus includes a catheter having a distal end and a proximal end. The distal end has an orifice through which a fluid can flow. The distal end has a port through which the fluid can flow. The port is adjacent to but apart from the orifice. The apparatus includes a mechanism for controlling the size of the port that is open. The controlling mechanism is disposed over the port and able to close the port. An apparatus for treating a patient. The apparatus includes a catheter having a proximal end and a distal end having an orifice through which a fluid can flow. The distal end has an end marker disposed about the orifice which appears in an image of an imaging device. An apparatus for treating a patient. The apparatus includes a catheter having a proximal end and a distal end having an orifice through which fluid can flow.

Abstract:

A perfusion cannula for treating a patient. The, cannula includes a hollow tube adapted for insertion into a vessel of the patient and adapted for fluid flow. The tube has a proximal end. The tube has a primary hole disposed in proximity to the proximal end for release of fluid from the tube and at least a first perfusion hole disposed in the tube wall for release of fluid from the tube. The cannula includes a widener extending from the outer surface of the tube and effectively extending the outer diameter of the tube. The inner diameter of the tube is smooth and continuous and has a circular, cross-section throughout. The widener is in spaced relation from the proximal end and in proximity to and in operational relation with the first perfusion hole wherein fluid in able to escape from the first perfusion hole without obstruction by the vessel wall when the tube is in the vessel wall. A perfusion cannula for treating a patient having at least a first ridge. A system for treating a patient.

Abstract:

A system for assisting the right heart of a patient includes a PA cannula adapted for insertion into a PA of a patient through the right internal jugular vein of the patient. The system includes a percutaneous RA cannula adapted for insertion into an RA of the patient. The system includes a blood pump disposed outside of the patient to which the RA cannula and the PA cannula are connected to provide right ventricular circulatory support to the patient without any left ventricular assist. A method for assisting the right heart of a patient includes the steps of inserting a PA cannula into a PA of a patient. There is the step of inserting an RA cannula into an RA of the patient. There is the step of connecting the RA cannula and the PA cannula to a blood pump disposed outside of the patient.
