Apparatus and method for packaging elongate surgical devices
A package for an elongate surgical device, such as a catheter, includes an elongate tube formed into a coil configuration with a first coil portion disposed adjacent to a second coil portion. A thermal weld bonds the coil portions in a fixed relationship and with a strength sufficient to prevent peeling the first coil portion from the second coil portion. The surgical device can then be loaded into the tube, pouched and sterilized for ultimate distribution. In an associated method, the tube is coiled on a turntable and moved relative to heating stations where the thermal bonds can be formed.
1. A package for an elongate surgical device, comprising:
an elongate tube having walls defining a lumen between a first end and a second end of the tube;
the tube being formed into a coiled configuration with a first coiled portion disposed adjacent to a second coiled portion, the first coiled portion being composed of a plastic material, the second coiled portion being composed of the plastic material; and
a curved thermal weld bonding the first coiled portion to the second coiled portion in a fixed, non-peelable relationship without additional adhesive materials.
2. The package recited in claim 1 wherein the thermal weld is continuous.
3. The package recited in claim 2 wherein:
the tube is formed into a stack of coils; and
the weld comprising a single continuous weld retaining the coils in a fixed relationship.
4. The package recited in claim 2 further comprising:
a backing card carrying the tube in the coiled configuration.
5. The package recited in claim 4 further comprising:
a pouch forming with the backing card a sterilizable, hermetically sealed, enclosure for the coiled tube.
6. The package recited in claim 4 wherein the backing card is composed of the plastic material.
7. The package recited in claim 1 further comprising:
a retaining accessory coupled to the first end of the elongate tube.
8. The package recited in claim 7 , wherein the retaining accessory is composed of the plastic material.
9. A package for an elongate surgical device, comprising:
an elongate tube having walls defining a lumen between a first end and a second end of the tube;
the tube being formed into a coiled configuration with a first coiled portion disposed adjacent to a second coiled portion, the first coiled portion and the second coiled portion being composed of a common material; and
a curved thermal weld bonding the first coiled portion to the second coiled portion in a fixed, non-peelable relationship.
10. The package recited in claim 9 , wherein the thermal weld comprises a separate bridge bond thermally bonded to the first coiled portion and the second coiled portion.
11. The package recited in claim 9 , wherein the tube and the separate bridge bond are composed of the common material.
12. The package recited in claim 9 , wherein the first coiled portion and the second coiled portion are disposed along a common plane.
13. The package recited in claim 9 , wherein the thermal weld is continuous.
14. The package recited in claim 9 , wherein the thermal weld is intermittent.
15. A package for elongate surgical devices, comprising:
a first elongate tube having walls defining a first lumen between a first end and a second end of the first tube;
the first tube being formed into a first coiled configuration with a first coiled portion disposed adjacent to a second coiled portion, the first coiled portion and the second coiled portion being composed of a common material;
a first curved thermal weld bonding the first coiled portion to the second coiled portion in a first fixed, non-peelable relationship;
a second elongate tube having walls defining a second lumen between a third end and a fourth end of the second tube;
the second tube being formed into a second coiled configuration with a third coiled portion disposed adjacent to a fourth coiled portion, the third coiled portion and the fourth coiled portion being composed of the common material; and
a second curved thermal weld bonding the third coiled portion to the fourth coiled portion in a second fixed, non-peelable relationship.
16. The package recited in claim 15 , wherein:
first coiled portion and the second coiled portion are disposed along a first plane; and
third coiled portion and the fourth coiled portion are disposed along a second plane above the first plane.
