Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
87 words
Tissue aperture repair apparatus (12) for providing a support for a weakened area (1,2,3) of a wall of a patient, said apparatus (12) comprising support sheet means (13) which, when in an expanded condition, serves to cover and protect the said weakened area, (1,2,3) and resilient means (22) for urging the support sheet means (13) to the expanded condition, characterised in that the resilient means (22) extends circumferentially about the support sheet means (13) in order to expand the latter to apply tension in the expanded condition.
Claim 2
Dependent Claim
28 words
Apparatus according to claim 1, characterised in that when used for open surgery, the resilient means (22) is fixed to the peripheral edge of the sheet means (13).
Claim 3
Dependent Claim
57 words
Apparatus according to claim 1, characterised in that the sheet means (13) comprises an attachment cavity (18) extending to the peripheral edge of the sheet means (13), and in that the resilient means (22) is in the form of a spring loaded wire (22) insertable into the cavity (18) in order to expand the sheet means (13).
Claim 4
Dependent Claim
53 words
Apparatus according to claim 3, characterised in that when used for minimally invasive surgery, the apparatus further comprises an introducer (21) through which the sheet means (13) is to be introduced in a folded condition into the patient, and through which the wire (22) is to be introduced into the attachment cavity (18).
Claim 5
Dependent Claim
63 words
Apparatus according to claim 4, characterised in that the sheet means (13) comprises two sheets (13,16) peripherally joined to form the said cavity (18), and in that means (46,47) are provided to connect the introducer (21) to an aperture (19) in one of the sheets to facilitate entry of the wire (22) into the said cavity (18), and to disconnect the introducer therefrom.
Claim 6
Dependent Claim
30 words
Apparatus according to any one preceding claim, further comprising a plurality of mutually angled flexible wires (114) extending centrally from a fastening means (116) on the said one sheet (113).
Claim 7
Dependent Claim
11 words
Apparatus according to claim 6, wherein the wire (114) is biodegradable.
Claim 8
Dependent Claim
29 words
Apparatus according to claim 6 or 7, characterised in that a thread (119) for fastening the said sheet (113) in a desired position extends from the fastening means (116).
Claim 9
Dependent Claim
29 words
Apparatus according to any one of claims 1 to 6 or 8, characterised in that the resilient means (22) is made from a material with superelastic shape memory properties.
