Abstract
Abstract A sternum plate set for securing a patient's ribcage following surgery and for protecting internal organs during subsequent surgical procedures. The plate set is constructed of biocompatible material intended to be implanted into a patient's body during a surgical procedure behind the sternum and to remain in contact with or as a substitute for the sternum following surgery. The plate set is slightly convex in shape on a side facing the sternum, and is provided with at least one transverse channel having a suture strand and passing therethrough. The suture strand has free ends which are equipped with curved needles and are passed through the sternum and joined together to secure the plate behind the sternum so that the plate permanently remains inside the patient's body between the sternum and internal organs.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
127 words
A sternum plate set for securing a patient's ribcage following surgery and for protecting internal organs during subsequent surgical procedures, comprising a plate of biocompatible material intended to be implanted into a patient's body during a surgical operation behind the sternum and to remain in contact with or as a substitute for the sternum, said plate having a slightly convex shape on a side facing said sternum, said plate being provided with at least one transverse channel having a suture strand passing therethrough, said suture strand having free ends intended to be passed through the sternum and joined together to secure the plate behind the sternum and resting against the sternum such that the plate permanently remains inside the patient's body between the sternum and internal organs.
Claim 2
Dependent Claim
127 words
A sternum plate set for securing a patient's ribcage following surgery and for protecting internal organs during subsequent surgical procedures, comprising a plate of biocompatible material intended to be implanted into a patient's body during a surgical operation behind the sternum and to remain in contact with or as a substitute for the sternum, said plate having a slightly convex shape on a side facing said sternum, said plate being provided with at least one transverse channel having a suture strand passing therethrough, said suture strand having free ends intended to be passed through the sternum and joined together to secure the plate behind the sternum and resting against the sternum such that the plate permanently remains inside the patient's body between the sternum and internal organs.
Claim 3
Dependent Claim
42 words
The plate set as set forth in claim 1, wherein the plate consists of a biocompatible material having the properties of harmlessness, nontoxicity and nonirritability, particularly of stainless steel or tantalum, or alternatively of polyester, polypropylene, polyethylene, polyvinylidene fluoride, polytetrafluoroethylene or polyhexafluoroethylene.
Claim 4
Dependent Claim
33 words
The plate set as set forth in either of claims 1 or 2, wherein said slightly convex shape of the plate adapts said plate for contact with the internal surface of said sternum.
