A fixation device is provided which includes a proximal nail portion and a distal plate portion. The nail portion includes a flexible tapered section, and a rigid distal section larger in diameter and is adapted to be inserted into a medullary canal of a fractured bone. The plate portion has a low, narrow profile and includes three longitudinally displaced peg holes, each of which is adapted to orient a peg in a different orientation from the others. The plate portion is adapted to be positioned on the outside of a fractured bone when the nail portion is within the medullary canal. The device provides the benefits of both an intramedullary nail and a bone plate in a single device. The fixation device permits a minimally invasive treatment of the metaphyseal fractures that may otherwise be undertreated.

A fixation system includes a device having a nail portion and a plate portion, preferably horizontally and vertically offset relative to the nail portion by a neck portion. The nail portion includes threaded screw holes, and the plate portion includes longitudinally displaced peg holes, each of which is adapted to orient a peg in a different orientation from the others. The system also includes unicortical screws having a reasonably large head adapted to seat against the outer surface of the bone and a threaded shaft adapted to engage in the screw holes, and pegs adapted to engage in the peg holes. Bone is clamped between the nail portion and the head of the unicortical screws. The pegs provide stabilization and support for subchondral fragments. Moreover, as the pegs preferably enter the subchondral fragments from a plurality of directions, additional fixation of the device into the bone is provided.

A heart stabilizer includes a shaft and two articulating arms coupled to a distal end of the shaft. At the end of each arm is a rotatable foot adapted to be angled relative to the heart wall contour and apply pressure against the wall of the heart to effectively eliminate motion of the heart wall between the feet. The stabilizer is adapted to be collapsible (foldable) to be inserted through the port device and locked longitudinally relative thereto. The stabilizer is also adapted to be deployed into an open configuration and then manipulated by actuation of a proximal control and actuation handle into a selected orientation.

Through-port heart stabilization system

A port device includes a tubular body sized to be inserted through a pair of ribs in a chest wall of a patient, a ball provided about the body, and a base defining a socket in which the ball is provided. Detent structure permits but limits longitudinal movement of the body relative to the ball. The base includes a clamping system which compresses the ball to lock the ball at a selected orientation within the socket and also immobilizes the port body relative to the ball. The distal end of the body includes a pair of swivels rotatably attached thereto. An obturator is extendable within the body maneuvers the swivels between a closed position (in which the swivels are oriented substantially parallel to the axis of the body), and an open position (in which the swivels are directed outward from the port).

An instrument stabilizer minimizes unwanted motion at the distal end of a surgical instrument by applying a damping force to the instrument. According to one embodiment, the instrument stabilizer preferably includes a cannula through which an instrument can extend, and a distal bushing adapted to contact the instrument. The instrument stabilizer also includes a proximal housing which includes a mechanism which applies a stabilizing or damping force to the proximal portion of the cannula. The mechanism which applies the force may be, by way of example, one or more of elastic bands, springs, struts, etc. When a surgical instrument is extended through the cannula and contacts the bushing, movement of the cannula and consequently the surgical instrument is damped by the stabilization force on the proximal portion of the cannula. In addition, a swivel device for angularly orienting the instrument stabilizer relative to a body of patient is also provided.

A system for performing through port off-pump coronary artery bypass surgery includes a port insertable between ribs into a chest wall of a patient, a heart stabilizer extendable through and stably couplable to the port, and an instrument stabilizer adapted to dampen extraneous movement to which a surgical instrument extending through the stabilizer is subject.

System for performing port off-pump beating heart coronary artery bypass surgery

A method for performing through-port off-pump beating heart coronary artery bypass surgery is provided. A port device is positioned in the chest wall and directed as necessary. A heart stabilizer is coupled to the port, and operated to apply a compressive force against the heart wall surrounding a location the required bypass such that the location is substantially immobilized. An instrument stabilizer includes a cannula which is inserted through a hole in the chest cavity, and the distal tip of the cannula is located adjacent the surgical site. The instrument stabilizer dampens movement of a surgical instrument, e.g., a scalpel or needle holder, extended therethrough. Once the bypass procedure is complete, the instruments, heart stabilizer, instrument stabilizers, and port are removed from the body of the patient.

A port device is insertable between the ribs of a patient and functions as an entryway for surgical instruments. The port device includes a tubular body having proximal and distal portions. The distal portion of the tubular body is coupled to a swivel adapted to be moved between a first orientation in which the swivel extends in substantially a same direction as the body, and a second orientation at an angle relative to, and preferably substantially perpendicular to, the first orientation. In the second orientation, the swivel engages the inside of the chest wall. The proximal portion of the tubular body has a clamping assembly which clamps the chest wall against the swivels to secure the port in its location. The port body can be anchored in a various angular positions.

A heart stabilizer includes a shaft and two articulating arms coupled to a distal end of the shaft. At the end of each arm is a rotatable foot adapted to be angled relative to the heart wall contour and apply pressure against the wall of the heart to effectively eliminate motion of the heart wall between the feet. The stabilizer is adapted to provide a stabilized area sufficiently large to allow an accurate anastomosis to be performed. According to preferred aspects of the invention, the stabilizer is particularly adapted to be collapsible (foldable) to be inserted through the port device and locked longitudinally relative thereto. The stabilizer is also preferably adapted to be automatically deployed into its final configuration by release of a lock actuated at a proximal portion of stabilizer extending outside the port. In addition, the stabilizer is adapted to automatically fold when being pulled back through the port. According to various embodiments of the heart stabilizer, the feet of the stabilizer may be further adapted to facilitate immobilization of the heart wall between the feet.

A port device includes tubular body with a distal swivel, a platform movable along the length of the port body, and preferably three legs movable relative to the platform. The tubular body is inserted through the chest wall, and the platform is then positioned over the proximal end of the tubular body and adjusted such that feet on the legs contact the chest wall and clamp the chest wall between the feet and the swivel. The legs may be individually adjusted to provide the tubular body at a desired angle relative to the chest wall. According to preferred aspects of the port device, the platform may be ratcheted relative to the port body and the feet may be ratcheted relative to the platform to permit rapid adjustment of the port relative to the patient.

A fracture fixation system is provided for the insertion of a fixation pin into the medullary canal of a fractured metacarpal, metatarsal, or phalangeal bone for stable bone fixation. The system includes one or more pins and an instrument for implanting the pins. According to one embodiment of the invention, the instrument includes a main handle and a pin handle movable relative to the main handle. The main handle includes a distal end, a drill coupled to the distal end, and a longitudinal slot which receives the pin handle. The drill includes a shaft having a distal boring tip and a groove proximal the boring tip for guiding the fixation pin. The pin handle is shaped and sized to slidably move within the longitudinal slot. Each pin preferably includes a curved, distal end. The distal end rests within the groove of the drill shaft. Movement of the pin handle within the slot of the main handle distally relative to the main handle causes the distal end of the pin to move relative to the drill shaft. In use, the main handle of the instrument is manipulated to subcutaneously introduce the drill into the metacarpal, metatarsal, or phalangeal base, and the pin handle is then moved relative to the main handle to introduce a pin into the bone until it extends through the medullary canal on either side of the fracture. Several pins may likewise be inserted to torsionally immobilization of the fracture.
