Abstract
Abstract An apparatus for stabilizing a predetermined area on a heart of a patient to enable a surgical procedure, the apparatus comprising a bifurcated member having two elongated prongs which can be adjustable as to width and an elongated handle segment attached to the bifurcated member. The handle segment can be either fixably or pivotably attached to the bifurcated member. The apparatus may further comprise an attachment or inlay to prevent lateral movement thereof when being used in the surgical procedure. The apparatus may also include a cleat for securing a portion of the surgical thread used during the surgical process. At least a portion of the prongs (or feet) of the bifurcated member may further be independently rotatable for self-alignment with the surface of the predetermined area of the heart.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
243 words
An apparatus for stabilizing a predetermined area of the heart of a patient to enable a surgical procedure, comprising: a. bifurcated member comprising elongated and generally parallel prongs, each prong having a proximal end portion and an opposite distal end portion and having a first section and a second section, the first section being adjacent the proximal end portion and terminating in the second section, the second section is adapted to engage the heart and is sized to stabilize the predetermined area of the heart; b. an elongated handle segment having a longitudinal axis and first end portion and an opposite second end portion, the elongated handle segment oriented at an obtuse angle relative to a portion of the bifurcated member; c. a connector on the first end portion of the handle segment for joining the handle segment to the proximal end portions of the prongs of the bifurcated member; d. a first member on the second end portion of the handle segment wherein the first member is rotatable generally about the longitudinal axis of the handle segment and movement of the prongs relative to the handle segment occurs during rotation of the first member; and e. wherein the second section of each of the prongs are oriented generally parallel to each other and the width between each of the prongs is adjustable so that the second section of each prong is movable relative to each other between first and second parallel positions.
Claim 2
Independent Claim
243 words
An apparatus for stabilizing a predetermined area of the heart of a patient to enable a surgical procedure, comprising: a. bifurcated member comprising elongated and generally parallel prongs, each prong having a proximal end portion and an opposite distal end portion and having a first section and a second section, the first section being adjacent the proximal end portion and terminating in the second section, the second section is adapted to engage the heart and is sized to stabilize the predetermined area of the heart; b. an elongated handle segment having a longitudinal axis and first end portion and an opposite second end portion, the elongated handle segment oriented at an obtuse angle relative to a portion of the bifurcated member; c. a connector on the first end portion of the handle segment for joining the handle segment to the proximal end portions of the prongs of the bifurcated member; d. a first member on the second end portion of the handle segment wherein the first member is rotatable generally about the longitudinal axis of the handle segment and movement of the prongs relative to the handle segment occurs during rotation of the first member; and e. wherein the second section of each of the prongs are oriented generally parallel to each other and the width between each of the prongs is adjustable so that the second section of each prong is movable relative to each other between first and second parallel positions.
