Integrated Cutting Guide with Cardioprotective Butterfly for Repeat Sternotomy and for Cast Cutting
A cardioprotective patch with an integrated cutting guide includes a membrane having a top edge, a bottom edge distal from the top edge, a right side edge connecting the top edge and the bottom edge; and a left side edge, distal from the right side edge and connecting the top edge and the bottom edge. A fold extends parallel to the top edge about half way between the top edge and the bottom edge. The crease is slit from the right side edge, forming a right slit. An elongate frame is fixedly connected to the membrane. The frame includes a tubular member and a plurality of arms extending outwardly from the tubular member and connected to the membrane.
STERNOTOMY CLOSURE TECHNIQUE USING POLYMERIC CABLE
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.
Sternal Bridge
A sternal bridge has a contiguous panel having a first length and a first height, a first U-shaped notch of a second height less than the first height and a first depth on one end of the contiguous panel, a second U-shaped notch of the second height and the first depth on an opposite end of the contiguous panel, a concave shape on a lower surface of the contiguous panel, and a first through hole passing from the lower surface of the panel through both sides of the first U-shaped notch, and a second through hole passing from the lower surface of the panel through both sides of the second U-shaped notch, the first and second through holes enabling the sternal bridge to be sutured onto the chest wall on either side.
STERNAL CLOSURE CERCLAGE, PLATE IMPLANT AND INSTRUMENTATION
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.
PRODUCTION METHOD FOR MEDICAL LINEAR MEMBER
A production method for a medical linear member is provided which is not abraded upon production and which includes a flat shape in a cross section.
The method includes the steps of: forming a first spiral body (1) of an oval shape in a horizontal section by spirally winding a base body (3), in which a plurality of wires (2) formed of a shape-memory alloy is arrayed, around a winding core (4); subjecting the first spiral body (1) to first shape-memory treatment; cutting the first spiral body (1) into a first predetermined length; forming a second spiral body (5) of a flat shape in a horizontal section by compressing the first spiral body (1) in a direction along a short diameter; subjecting the second spiral body (5) to second shape-memory treatment; and removing the winding core (4) from the second spiral body (5).
Implant positioning devices and methods
Implant positioning devices and fastener guides for implant positioning devices are disclosed for assisting in positioning orthopaedic fixation devices (such as bone plates, etc.). A fastener guide may include a body with slits in a first end of the body that form a guide arm proximal to the first end of the body. The guide arm is configured to releasable hold a fastener in the fastener guide. The fastener guide may also be coupled to a bone plate to facilitate ease of alignment and insertion of the fastener into a fastener apertures of the bone plate.
Implant positioning devices and methods
A device for positioning an orthopaedic fixation device includes: a compression attachment mechanism; a fastener guide coupled to the compression attachment mechanism; and a spring member disposed in the fastener guide. The compression attachment mechanism is biased toward a closed position and comprises a gripping portion that is movable by a user for transitioning the compression attachment mechanism from the closed position toward an open position for loading a plate onto the compression attachment mechanism.
Surgical tool and method of use
The present disclosure generally relates to a surgical tool for use in shoulder arthroplasty. The surgical tool includes a humeral head cut guide configured to fit within a rotator interval of a subject in need of shoulder arthroplasty. The cut guide can further include a top surface, a bottom surface, a front surface, a back surface, and at least two sides. The surgical tool can also have at least two nonconverging pin holes and a receiving portion configured to permit reversible attachment of the cut guide to an attachment arm assembly.
APPARATUS AND METHODS FOR INTRODUCING PORTALS IN BONE
An apparatus and method for introducing portals into bone is described herein. An example apparatus for introducing portals into bone includes a handle, a base, and a driving member. The driving member can be made to project past the base by operating the handle. The base is detachable from the handle. The apparatus also includes a guide coupled at a first end to the handle and at a second end to the base. The base is detachably coupled to the guide. A base coupling detachably coupling the base to the guide includes an actuating member movable between a coupled configuration wherein the base is coupled to the guide and an uncoupled configuration wherein the base is released from the guide. The actuating member is arranged so that motion of the handle toward the base moves the actuating member from the coupled configuration to the uncoupled configuration.
