Abstract

An endoprosthesis is conditioned prior to use within a patient by placing a scaffold of the endoprosthesis in contact with a sterile liquid optionally at body temperature, following by causing the scaffold to bend. The scaffold may be bent by moving the scaffold through a conditioning tube.

First claim

What is claimed is:

1. A method for conditioning an endoprosthesis prior to use within a patient, the method comprising:
opening a sterilized package containing the endoprosthesis, the endoprosthesis including a scaffold having a substrate formed of a bioresorbable polymer material; followed by
placing the scaffold in contact with a sterile liquid; followed by
causing the scaffold to bend along a longitudinal axis of the scaffold before the endoprosthesis is used within a patient,
wherein said causing the scaffold to bend includes moving the scaffold through a passageway within a conditioning tube, said moving includes moving the scaffold through at least one turn of the passageway;
withdrawing the scaffold out of the passageway of the conditioning tube after said moving the scaffold through the passageway; and
followed by introducing the endoprosthesis into a human or animal body.

2. The method of claim 1 , wherein said placing the scaffold in contact with the liquid includes any one or a combination of:
introducing the liquid into a carrier tube that contains the scaffold, and
placing the scaffold into a container of the liquid.

3. The method of claim 1 , wherein the endoprosthesis is disposed on a catheter, and said causing the scaffold to bend includes any one or a combination of pushing and pulling the catheter such that the scaffold moves through the at least one turn of the passageway within the conditioning tube.

4. The method of claim 1 , wherein a sheath is disposed around the scaffold, and the method further comprises removing the sheath from around the scaffold, said removing performed either (a) at a time between said opening the sterilized package and said placing the scaffold in contact with the liquid or (b) at a time between said placing the scaffold in contact with the liquid and said causing the scaffold to bend.

5. The method of claim 1 , wherein said opening of the sterilized package includes breaking a seal of the sterilized package, the sterilized package and scaffold having been sterilized prior to said breaking of the seal, and the method further comprises removing the scaffold from the sterilized package either (a) at a time between said breaking of the seal and said placing the scaffold in contact with the liquid or (b) a time between said placing the scaffold in contact with the liquid and said causing the scaffold to bend.

6. A method for conditioning an endoprosthesis prior to use within a patient, the method comprising:
opening a sterilized package containing the endoprosthesis, the endoprosthesis including a scaffold having a substrate formed of a bioresorbable polymer material; followed by
placing the scaffold in contact with a sterile liquid; followed by
causing the scaffold to bend along a longitudinal axis of the scaffold before the endoprosthesis is used within a patient,
wherein said causing the scaffold to bend includes moving the scaffold through a passageway within a conditioning tube, said moving includes moving the scaffold through at least one turn of the passageway,
wherein the endoprosthesis is disposed on a catheter, and said causing the scaffold to bend includes any one or a combination of pushing and pulling the catheter such that the scaffold moves through the at least one turn of the passageway within the conditioning tube,
wherein the catheter and scaffold are disposed within a carrier tube, the carrier tube includes a first segment and a second segment, the method further comprises:
pulling the catheter partially out of the first segment such that the scaffold moves from the second segment to the first segment, said pulling is performed at a time between said opening the sterilized package and said causing the scaffold to bend, and
wherein said causing the scaffold to bend includes pushing the catheter into the first segment such that the scaffold moves through the at least one turn of the passageway within the conditioning tube.

7. The method of claim 6 , further comprising withdrawing the scaffold out of the passageway of the conditioning tube after said moving the scaffold through the passageway.

8. The method of claim 6 , wherein when opening the sterilized packaged, the conditioning tube has already been attached to a region of the carrier tube, and the conditioning tube remains attached to said region of the carrier tube during said pulling the catheter partially out the first segment of the carrier tube and during said pushing the catheter into the first segment of the carrier tube.

9. The method of claim 6 , further comprising attaching the conditioning tube to the carrier tube, said attaching performed at a time between said pulling the catheter partially out the first segment of the carrier tube and said pushing the catheter into the first segment of the carrier tube.

10. The method of claim 6 , wherein said attaching of the conditioning tube to the carrier tube is performed by replacing the second segment of the carrier tube with the conditioning tube such that the first segment of the carrier tube becomes attached to the conditioning tube.

11. The method of claim 6 , wherein the carrier tube is a coiled tube having an arc degree of at least 360 degrees.
