Abstract: Disclosed is a medical device comprising an incision assembly coupled to a catheter and an incision opening defined along the incision assembly. A retractable cutting apparatus is disposed within the incision opening and comprises a first incision member comprising at least one first cutting surface and defining a first member proximal end rotatably fixed proximate to a distal end of the incision opening and the at least one cutting surface is located on a bottom edge of the first incision member. A second incision member comprises at least one second cutting surface and defines a second member distal end attached to the first incision member at a connection point between a first member distal end and the first member proximal end of the first incision member, and wherein the at least one second cutting surface is located on a bottom edge of the second incision member.

Abstract: A medical device includes an incision device operably coupled to a distal end of an elongate catheter. The incision device includes an incision channel, and a retractable cutting apparatus disposed within the incision channel. The retractable cutting apparatus includes a first cutting apparatus link that is rotatably fixed proximate to a distal end of the incision channel and a second cutting apparatus link that is attached to the first link proximal end of the first cutting apparatus link. The first cutting apparatus preferably includes a first cutting surface proximate to the first link proximal end of the first cutting apparatus link and the second cutting apparatus link includes a second cutting surface. The retractable cutting apparatus also includes a guide member coupled to cause the retractable cutting apparatus to move between a retracted position and a deployed position.

Abstract: Methods of improving a heart function in a heart of a subject having heart dysfunction are described. An exemplary embodiment includes accessing a pericardial cavity of the heart and advancing a cutting device within the pericardial cavity to a first incision point. At least a parietal layer of a pericardium of the heart is then pierced. A cutting device is placed against the parietal layer and retracted along a selected cut path so as to create a first incision having a selected length in at least the parietal layer to reduce pressure exerted on the heart by the pericardium. The above operations are repeated to create one or more additional incisions along respective additional cut paths.

Abstract: A medical device for creating elongated incisions within a pericardium is provided. The medical device includes an incision device operably coupled to a distal end of a catheter. The incision device includes an incision channel defined along the incision device. The medical device further includes a retractable cutting apparatus disposed within the incision channel. The retractable cutting apparatus includes a blade structured to move between a retracted position and a deployed position. In an instance in which the blade is in the retracted position, the blade is disposed within the incision channel. In an instance in which the blade is in the deployed position, the blade at least partially protrudes from the incision channel. The medical device further includes a cutting apparatus actuation mechanism structured to move the blade between the retracted position and the deployed position within a human body.

Abstract: A method of infusing a solution to a target site in a patient is described. In one application, the method may be used for infusing a solution into a kidney. A cannula catheter includes a catheter shaft, the catheter shaft having a first lumen extending from a proximal end of the catheter shaft to a side opening along a distal portion. A cannula shaft of an infusion cannula can be pre-loaded within the first lumen. The method may include advancing the cannula shaft and the catheter shaft along a guidewire. The method can further include withdrawing the guidewire and advancing the cannula shaft relative to the catheter shaft for advancing a distal end of the cannula shaft through the side opening, thereby facilitating infusion of a solution from the cannula shaft to the target site.

Abstract: According to certain aspects, an implant device comprises an outer member configured to position the implant device within one or more pulmonary vessels. The implant device also comprises an inner member comprising one or more blades configured to modify one or more of forward waves or backward waves within the one or more pulmonary vessels to reduce interference between the forward waves and the backward waves during systole, the one or more blades having a shape or surface that directs a portion of the forward waves to a region of the one or more pulmonary vessels.
