Abstract
Abstract A pouch to at least partly enclose a heart ( 1 ), the wall of the pouch ( 2 ) being elastic. The purpose of the pouch is to enclose at least part of a heart ( 1 ) and to oppose excessive dilation of the heart ( 1 ) that might be due to inflammatory disease of the heart muscle, for instance a viral infection or an autoimmune process. In many cases the use of such a pouch ( 2 ) may circumvent the need for a heart transplant.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
37 words
A pouch adapted to at least partly enclose a heart, the pouch comprising elastic and inelastic material, wherein the elastic material determines a stretching function of the pouch and the inelastic material determines a stretching limit value.
Claim 2
Dependent Claim
37 words
A pouch adapted to at least partly enclose a heart, the pouch comprising elastic and inelastic material, wherein the elastic material determines a stretching function of the pouch and the inelastic material determines a stretching limit value.
Claim 3
Dependent Claim
20 words
The pouch according to claim 1 , wherein the elastic material comprises threads into which are incorporated substantially inelastic threads.
Claim 4
Dependent Claim
23 words
The pouch according to claim 2 , wherein the substantially inelastic threads are incorporated into the elastic material in a longitudinally displaceable manner.
Claim 5
Dependent Claim
30 words
The pouch according to claim 1 , wherein the inelastic threads comprise one or more crimps, one or more pleats, or accordion geometry that help determine the stretching limit value.
Claim 6
Dependent Claim
25 words
The pouch according to claim 2 , wherein the inelastic threads have a longitudinal direction, and the threads are crimped transversely to their longitudinal direction.
Claim 7
Dependent Claim
13 words
The pouch according to claim 5 , wherein the crimps are thermally set.
Claim 8
Dependent Claim
18 words
The pouch according to claim 5 , wherein the threads are crimped in a wavy or zig-zag manner.
Claim 9
Dependent Claim
68 words
The pouch according to claim 3 , wherein the pouch has a shape and volume, the heart has a shape and volume at maximum diastolic filling, and the substantially inelastic threads are adjustable in length such that at least one of the shape or volume of the pouch is adapted to correspond to at least one of the shape or volume of the heart at maximum diastolic filling.
Claim 10
Dependent Claim
18 words
The pouch according to claim 1 , wherein the elastic material comprises a sheet, fabric or a knit.
Claim 11
Dependent Claim
54 words
A pouch adapted to at least partly enclose a heart, the pouch comprising: elastic material comprising threads with substantially non-elastic threads incorporated therein, the pouch defining an aperture edge and a substantially opposite pouch tip, wherein the substantially inelastic threads run from the aperture edge of the pouch to the substantially opposite pouch tip.
Claim 12
Dependent Claim
54 words
A pouch adapted to at least partly enclose a heart, the pouch comprising: elastic material comprising threads with substantially non-elastic threads incorporated therein, the pouch defining an aperture edge and a substantially opposite pouch tip, wherein the substantially inelastic threads run from the aperture edge of the pouch to the substantially opposite pouch tip.
Claim 13
Dependent Claim
18 words
The pouch according to claim 10 , wherein the elastic material comprises a sheet, fabric or a knit.
Claim 14
Dependent Claim
52 words
A pouch adapted to at least partly enclose a heart, wherein the pouch comprises an elastic wall comprising two kinds of thermoplastic threads or fibers, one kind of which is of a higher shaping temperature than the other kind, the one kind being elastic and the other kind being relatively less elastic.
Claim 15
Dependent Claim
52 words
A pouch adapted to at least partly enclose a heart, wherein the pouch comprises an elastic wall comprising two kinds of thermoplastic threads or fibers, one kind of which is of a higher shaping temperature than the other kind, the one kind being elastic and the other kind being relatively less elastic.
Claim 16
Dependent Claim
12 words
The pouch according to claim 12 , wherein the plastic is thermoplastic.
