摘要： This document describes devices used during surgical procedures for the treatment of heart conditions. For example, this document describes technology to monitor the operations of a heart-lung machine and then shows associated read outs on a head-worn display in order to provide an augmented-reality presentation. For example, various sensors on and around a heart-lung machine, patient, and/or extracorporeal circuit can monitor the operations of the procedure using the heart-lung machine.

摘要： Extracorporeal blood flow circuit devices can be used during medical procedures such as on-pump open-heart surgery. For example, extracorporeal heat exchange and oxygenation devices can be used to facilitate surgical procedures such as coronary artery bypass grafting. In some embodiments, such an oxygenation device can include an integrated air removal structure. In particular embodiments, the air removal structure can comprise one or more porous hollow fibers.

摘要： A surgical stabilizer arm ends with a hybrid quick connect mechanism capable of holding tissue manipulator tools of either the ball type or the shaft type. The single integrated mechanism allows users to choose the type of attachment mechanism they prefer on a case-by-case basis. The mechanism has a spring-loaded sleeve that can be pulled back to enable an attachment (manipulator tool) to be inserted. A ball-style attachment is inserted through an opening in a grip cage, and a shaft-style attachment is inserted into an actuator (e.g., spring detent) through the claws of the grip cage. When the sleeve is released, a compression spring pushed the actuator forward, either pressing the ball attachment against the grip cage or pressing the spring detent against the shaft attachment to partially lock the attachment in place. Tightening a tension cable increases the pressure to fully lock the attachment in place.

摘要： A heart rotator tool uses a malleable guide rail with a distal end adapted to conform to a desired shape along a surface of a heart tissue. A suction cup is adapted for grasping the heart tissue. A slider is slidably mounted on the guide rail which is flexible to conform to the shape of the guide rail while sliding, the slider having a distal end connected to the suction cup and having a proximal end for providing a handgrip. A vacuum tube is joined to the suction cup and carried by the slider. The vacuum tube is adapted to selectively (i.e., selectably couple a vacuum source to the suction cup. After arranging the guide rail around the heart and sliding the suction cup to a desired position, the vacuum is activated and subsequent sliding of the suction cup via movement of the handgrip rotates the heart as desired.

摘要： A device prepares leaflets for cardiovascular valve reconstruction from a pericardial tissue sheet harvested from a patient. A cutting tool is adapted to cut a predetermined pattern having a selected leaflet size. The device is continuously adjustable using a plurality of slidable blade segments forming a closed periphery. Radially-slidable links are slidably attached to respective blade segments. An adjustment disc is coupled to the links, wherein rotation of the adjustment disc varies a radial position of the links to modify an overlapping of the blade segments in order to select a corresponding size of the closed periphery.

摘要： A vessel dissector for harvesting a target vessel from a donor has a generally cylindrical tip body with a sloping channel formed along a longitudinal side. A channel bottom provides a channel depth that decreases from a distal channel end to a proximal channel end. The tip body has a crescent-shaped forward lip extending distally from the channel. An arcuate collar is slidably disposed in an arcuate recess within the tip body to selectably bridge the channel at the distal end of the channel to form a ring profile with the forward lip. A first ferromagnetic heating element is disposed along a radially outward surface of the forward lip. A second ferromagnetic heating element is disposed on a distal edge of the arcuate collar. The first and second ferromagnetic heating elements are adapted to be energized simultaneously to make a vasiform cut including a pedicle around the target vessel.

摘要： Apparatus for marking a blood vessel for use as a bypass graft in a patient includes a preparation plate for supporting an isolated blood vessel that is in a state for anastomosing to the patient. A stencil plate is configured for overlying the blood vessel and preparation plate, wherein the stencil plate has an opening adapted to expose a portion of the blood vessel to a dye applied through the opening. The stencil plate around the opening is adapted to shield the blood vessel from the dye. A dye applicator is configured to direct a metered amount of the dye through the opening and onto the exposed portion of the blood vessel, preferably as a mist. Preferably, the opening is a lineal slot for creating a guide line extending longitudinally along an outer wall of the blood vessel.

摘要： A blunt dissector for endoscopic vein harvesting has a generally-cylindrical sheath for retaining an elongated endoscope. The sheath is elongated between a distal end and a proximal end. A transparent tip is disposed at the distal end of the sheath.A handle is disposed at the proximal end of the sheath. The sheath includes a selectably closable longitudinal slot having an opened configuration such that the endoscope can be inserted radially into the sheath. The longitudinal slot has a closed configuration that retains the endoscope within the sheath and presents a substantially it) smooth outer surface for use during dissection.
