Abstract
Abstract The device is to keep a collapsible/restorable elastic artificial blood vessel 1 in a collapsed condition, to transport the artificial blood vessel 1 to a target position and subsequently to restore the artificial blood vessel 1 into a predetermined shape by releasing it from the collapsed condition. The device comprises wrapping members 51, 52 which are generally flat when spread and wires 53, 54 which hold each of the wrapping members 51, 52 in a condition of being rolled, wherein each of a body portion 2 and a branch portion 3 of the artificial blood vessel 1 is contained inside the wrapping members 51, 52 held by the wires 53, 54 in a collapsed condition and the wires 53, 54 are separated from the wrapping members 51, 52 at the target position to spread the wrapping members 51, 52 so as to release the artificial blood vessel 1.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
214 words
A collapsing device in combination with a collapsible/restorable elastic appliance, comprising: a collapsing device having: a first wrapping member which is generally flat when spread and a first retaining member which keeps the first wrapping member in a condition of being rolled and a second wrapping member which is generally flat when spread and a second retaining member which keeps the second wrapping member in a condition of being rolled; and a collapsible/restorable elastic appliance having a tubular body portion and a tubular branch portion which branches from a part of the tubular body portion, with the internal space of the branch portion communicating with the internal space of the tubular body portion, wherein the appliance is arranged so that the body portion is contained in a collapsed condition inside the first wrapping member held in a rolled condition by the first retaining member and the branch portion is contained in a collapsed condition inside the second wrapping member held in a rolled condition by the second retaining member, and the collapsing device keeps the appliance in a collapsed condition for transport to a target position and permits restoration of the appliance into a predetermined shape by releasing the appliance from the collapsed condition when the retaining members are separated from the wrapping members.
Claim 2
Dependent Claim
214 words
A collapsing device in combination with a collapsible/restorable elastic appliance, comprising: a collapsing device having: a first wrapping member which is generally flat when spread and a first retaining member which keeps the first wrapping member in a condition of being rolled and a second wrapping member which is generally flat when spread and a second retaining member which keeps the second wrapping member in a condition of being rolled; and a collapsible/restorable elastic appliance having a tubular body portion and a tubular branch portion which branches from a part of the tubular body portion, with the internal space of the branch portion communicating with the internal space of the tubular body portion, wherein the appliance is arranged so that the body portion is contained in a collapsed condition inside the first wrapping member held in a rolled condition by the first retaining member and the branch portion is contained in a collapsed condition inside the second wrapping member held in a rolled condition by the second retaining member, and the collapsing device keeps the appliance in a collapsed condition for transport to a target position and permits restoration of the appliance into a predetermined shape by releasing the appliance from the collapsed condition when the retaining members are separated from the wrapping members.
Claim 3
Dependent Claim
86 words
The collapsing device in combination with a collapsible/restorable elastic appliance as described in claim 1 , wherein the body portion comprises intermittently arranged ring members bridged by a first flexible cover and the branch portion comprises intermittently arranged ring members bridged by a second flexible cover which branches from a part of the body portion, wherein the body portion and branch portion of the appliance are so arranged that each of the ring members is collapsed into a wavy shape having a peak and a valley.
Claim 4
Dependent Claim
259 words
A method of using a collapsing device in combination with a collapsible/restorable elastic appliance as described in claim 1 , characterized by that the first wrapping member is mounted near an end portion of an outer circumference of a pipe member, the body portion and the branch portion of the appliance are inserted together into the pipe member at a position corresponding to the position where the first wrapping member is mounted and the first wrapping member and the body portion are drawn simultaneously out of the pipe member in a condition that both of the first wrapping member and the body portion are restrained from moving interactively at the end portion so as to contain the body portion and the branch portion of the appliance together inside of the first wrapping member, and subsequently a part of the first wrapping member is released from a condition of being held by the first retaining member and the branch portion is drawn out through the part of the first wrapping member and then the second wrapping member is mounted near an end portion of an outer circumference of a pipe member, the branch portion inserted into the pipe member and corresponding to the position where the second wrapping member is mounted and the second wrapping member and the branch portion are drawn simultaneously out of the pipe member in a condition that both of the second wrapping member and the branch portion are restrained from moving interactively so as to contain the branch portion inside of the second wrapping member.
Claim 5
Dependent Claim
58 words
The method of using the collapsing device in combination with a collapsible/restorable elastic appliance as described in claim 3 , wherein the first wrapping member is made to open wider gradually along a tapered guide portion and then to be mounted on an outer circumference of the pipe member arranged at a position continuous to the guide portion.
Claim 6
Dependent Claim
263 words
A collapsing device in combination with a collapsible/restorable elastic appliance, comprising: a collapsing device having: a first wrapping member which is generally flat when spread and a first retaining member which keeps the first wrapping member in a condition of being rolled and a second wrapping member which is generally flat when spread and a second retaining member which keeps the second wrapping member in a condition of being rolled, wherein at least one of the first and second retaining members comprises a string which sews edges of a respective one of the first and second wrapping members and is arranged such that a retaining rod is passed through a loop formed at an end portion of the string; and a collapsible/restorable elastic appliance having a tubular body portion and a tubular branch portion which branches from a part of the tubular body portion, with the internal space of the branch portion communicating with the internal space of the tubular body portion, wherein the appliance is arranged so that the body portion is contained in a collapsed condition inside the first wrapping member held in a rolled condition by the first retaining member and the branch portion is contained in a collapsed condition inside the second wrapping member held in a rolled condition by the second retaining member, and the collapsing device keeps the appliance in a collapsed condition for transport to a target position and permits restoration of the appliance into a predetermined shape by releasing the appliance from the collapsed condition when the retaining members are separated from the wrapping members.
