An organizer is provided for holding surgical forceps in a ready position. Each surgical forceps includes a pair of shanks with distal tips, proximal ring handles, and a ratchet mechanism adjacent the ring handles. The organizer has a base, and a wedge-shaped core projecting upwards along a vertical axis from the base. The core has a profile adapted to fit within a respective opening of each respective forceps bounded by the shanks and the ratchet mechanism when the ratchet mechanisms are engaged. A plurality of wings project radially from the core to define a plurality of substantially U-shaped channels between adjacent wings. The channels are configured to nest the shanks of the forceps so that the respective forceps are locked in the grooves by their respective ratchet mechanisms.

Hemostat organizer

A mounting device holds a sensor, such as an ultrasonic fluid level sensor, against a side of a reservoir, such as a blood reservoir in an extracorporeal blood circulation system. Flexible foot pads in a base sheet carry an adhesive coating for attaching the footpads to an arbitrarily shaped outer wall of the reservoir. A rigid bayonet-type locking connector which receives the sensor is suspended from the base sheet by a tubular coupling member which preferably includes a resilient section that flexes to maintain the sensor in an orthogonal relationship with the reservoir wall. The resilient section preferably includes helical arms which are under tension when the sensor is locked into place in order to create a desirable amount of preload force between the sensor and the wall.

Flexible sensor mount for hard shell blood reservoir

A device for joining individual leaflets for repairing a cardiac valve of a patient has a base and projection fingers rising from the base to support adjacent leaflets for tacking together by sewing overlapping edges of adjacent leaflets prior to emplacement into the patient. The invention provides a cutting tool for excising leaflets from a pericardial tissue sheet according to predetermined sizes and shapes. A leaflet having a desired contour and size is obtained by pressing the tool formed as a cutter block against the tissue sheet. A set of blocks can be provided wherein each cutter block has an outer edge following a respective contour and size for a leaflet, and wherein the outer edge includes a raised cutting edge for pressing through the pericardial tissue sheet. The blocks can be held in a press for assisting in pushing the cutting edge through the tissue.

A vessel dissector for harvesting a target vessel has a tubular member carrying a blunt transparent tip with a terminus for blunt dissection of tissue and a base affixed to the tubular member. An active ring set has first and second ring segments mounted to distal ends of respective manipulator bars in the tubular member. The ring segments juxtapose to define a closed loop with an inner diameter larger than the outside diameter of the tip base. The ring segments are movable between a retracted position nested at the base and respective extended positions distally forward of the terminus. At least one of the ring segments is energizable to cut and cauterize a cylindrical pedicle including the target vessel. The ring segments independently extend longitudinally to provide a variable gap between the ring segments to capture, cut, and cauterize side branches to the target vessel between the ring segments.

Endoscopic vessel harvester with blunt and active ring dissection

An endoscopic harvesting device removes a vessel from a body. The vessel has an anterior side closest to the skin. A sheath extends in a longitudinal direction with a dissector tip for advancing along the vessel substantially along the anterior side to create a flanking tunnel spaced away from the vessel. A ring-shaped blade is mounted to the sheath and is disposed in a plane substantially perpendicular to the longitudinal direction and proximal of the dissector tip. The blade forms a lateral loop to encircle the vessel from the flanking tunnel. The blade comprises an inductively-heated ferromagnetic member configured to make a vasiform cut including a pedicle around the vessel as the sheath advances.

Single-pass endoscopic vessel harvesting

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.
