An anchor assembly, for securing a first portion and a second portion of a separated sternum, can include a lock, an anchor, and a cerclage. The anchor can include a body locatable between the first portion and the second portion of the sternum, where the body can define an end portion. The anchor can include a collar connected to the body and extending outward from the end portion of the body. The collar can engage an outer surface of the sternum to limit movement of the body beyond the outer surface of the sternum. The cerclage can be connected to and can extend from the anchor. The cerclage can be configured to at least partially surround the first portion and the second portion of the separated sternum.

A tensioning tool is provided for applying tension to a band. The tensioning tool includes a handle. The tensioning tool also includes a barrel having a channel at an end of the barrel. The channel is configured to receive a portion of the band. The tensioning tool also includes a cutting blade that is configured to remove an excess portion of a band. The tensioning tool has a tension limit that is the maximum tension that can be applied to a band, and the tensioning tool is configured to apply tension to the band until the tension limit has been reached. The tensioning tool is configured to actuate the cutting blade to cut the band upon at least one of the tension limit being reached or upon a user command.

The invention relates to a sternal closure device for temporarily closing and stabilizing a sternum in between surgeries of the thoracic cavity wherein a C-shaped hook attaches to the outside of the portion of one side of a dissected sternum which is connected to an opposing C-shaped hook by a wire which may be readily cut with surgical scissors to allow physicians quick access to the thoracic cavity for surgical treatment. The device includes a stress measurement dial that allows physicians to evaluate the force needed for permanent closure fixation. The new and unique aspect of this invention is that it gives surgeons easy access to the thoracic cavity without worrying about the sternal bones fusing together between operations.

A system for providing a bone cerclage according to an exemplary aspect of the present disclosure includes, among other things, a suture passer including a shaft. The shaft includes a passageway and a slot leading to the passageway. The slot has a variable width along a length of the passageway. A method is also disclosed.

A plate system for securing a first sternal portion and a second sternal portion of a separated sternum can include a first plate and a second plate. The first plate can include a first body and a first hook. The first body can include a first reduction bore. The first hook can extend from the first body. The first hook can be engageable with a lateral portion of the first sternal portion. The second plate can include a second body and a second hook. The second body can include a second reduction bore. The second hook can extend from the second body. The second hook can be engageable with a lateral portion of the second sternal portion opposite the first hook.

A system including a bone punch tool and a needle guide. The bone punch tool can include a support arm having a support arm proximal portion and a support arm distal portion, a pivot arm having a pivot arm proximal portion and a pivot arm distal portion, and an arcuate punch configured to punch through bone. The pivot arm distal portion can be pivotably coupled to the support arm distal portion, such that the pivot arm proximal portion is configured to be moved away from the support arm proximal portion to extend the arcuate punch into a punch position to punch an arcuate hole through bone. The needle guide can be configured to guide a needle through the arcuate hole.

Embodiments herein provide a chest wall repair plate device where a central portion of the device is comprised of an elastomer to allow for rapid resection using a standard surgical scalpel should there be a need to quickly re-enter the chest cavity. The elastomeric section adjoins two or more rigid plate sections creating a simple, easily removable sternal stabilization system.

A sternotomy closure technique is suitably carried out with a cerclage mechanism, which is capable of maintaining proper bony compression (within a desired range) across the sternum cut, in spite of a range of external forces and significant lateral distraction due to these external forces. The sternum fragments are aligned in apposition disposed around a longitudinal seam and secured with a resilient element. The resilient element is tensioned to a desired tension to compress the sternum to a desired compression range. The resilient element is then elongated and contracted while accepting multiple cycles of physiological distracting forces across the sternum while maintaining contact pressure across the longitudinal seam within a desired range for a length of time sufficient for bony healing. The resilient element is preferably a polymer cable comprising an elongated elastic polymeric core coaxially surrounded by a sheath woven from ultra-high molecular weight polyethylene strands.

Provided is an implant for sternum replacement including an upper face, a posterior face, extensions for fitting with the ribs and extensions for fitting with the manubrium, wherein that implant is manufactured in a single piece with high performance engineering polymers, with an anatomical adjustment tailored to each patient, which guarantees the reduction of the number of elements in contact with the patient, facilitating and speeding up the surgical procedure, at the same time, the required mechanical and flexibility properties, are guaranteed.

A quick release sternum closing fixator has a locking roller, and a male fixing piece and a female fixing piece that can be plugged together. The male fixing piece has an elastic plug and the first claw hook plate. The elastic plug has the first serration on both sides and a tightening groove in the middle, thus forming two elastic claws. A tensioning device forces the two elastic claws to move against each other is provided between the said locking roller and the two elastic claws. After the locking roller rotates, when the elastic claws on the male fixing piece lose resilience due to the growth of human tissues, the two elastic claws can be forcibly pulled back to the initial state by rotating the locking roller, thus smoothly and quickly opening the sternum closing fixator.
