Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
70 words
A housing for surgical implantation having an encased sealant for repairing hypodermic punctures, wherein the improvement comprises: a generally dome shaped sealant layer sandwiched between inner and outer wall portions of the housing; and the wall portions are domed in a common direction to provide a reservoir chamber under the domed inner wall, whereby hypodermic punctures into the housing can be made through the sealant layer from widely angled positions.
Claim 2
Dependent Claim
70 words
A housing for surgical implantation having an encased sealant for repairing hypodermic punctures, wherein the improvement comprises: a generally dome shaped sealant layer sandwiched between inner and outer wall portions of the housing; and the wall portions are domed in a common direction to provide a reservoir chamber under the domed inner wall, whereby hypodermic punctures into the housing can be made through the sealant layer from widely angled positions.
Claim 3
Dependent Claim
24 words
A housing as set forth in claim 1, wherein the inner wall portion is generally dome shaped and of a generally constant wall thickness.
Claim 4
Dependent Claim
24 words
A housing as set forth in claim 1, wherein the outer wall portion is generally dome shaped and of a generally constant wall thickness.
