Abstract
The present disclosure describes systems and methods of forming a continuous reinforced catheter shaft having multiple coiled wire structures. A method includes providing of a first spool having a liner rolled thereon and unrolling at least a portion of the liner from the first spool. The method also includes coiling a reinforcing wire on at least the portion of the liner unrolled from the first spool to form a plurality of coiled wire structures and an interim portion of the reinforcing wire coiled adjacent coiled wire structures. The method also includes securing a jacket over the plurality of coiled wire structures and the interim portion of the reinforcing wire coiled to form a continuous shaft having the plurality of coiled wire structures.
Claims20
A method of manufacturing a sheath, the method comprising:
- providing an elongate member comprising a liner disposed on an outer surface of a wire;
- disposing the elongate member such that a portion of the elongate member is suspended between a first support point and a second support point;
- translating the suspended portion of the elongate member in a first direction;
- disposing a first coil of a reinforcing wire onto the suspended portion of the elongate member as the suspend portion is translated in the first direction;
- translating the suspend portion in a second direction;
- and
- disposing a second coil of the reinforcing wire onto the suspended portion as the suspend portion is translated in the second direction.
A sheath comprising:
- an inner layer defining a lumen of the sheath;
- a coiled wire structure disposed on an exterior circumferential surface of the inner layer, the coiled wire structure comprising:
- a first coil comprising a reinforcing wire coiled in a first direction;
- and
- a second coil comprising a reinforcing wire coiled in a second direction;
- an outer layer disposed on the exterior circumferential surface of the coiled wire structure.
A system for coiling reinforcing wire around a liner, the system comprising:
- a first spool having liner rolled thereon, the liner having a metal wire disposed therein;
- a spool of reinforcing wire;
- a coiling assembly configured to:
- coil the reinforcing wire on a portion of the liner as the liner is unrolled from the first spool to form a first coil of a coiled wire structure;
- and
- coil the reinforcing wire on the portion of the liner unrolled from the first spool as it is rolled onto the first spool to form a second coil of a coiled wire structure;
- a jacket assembly configured to secure a jacket over the coiled wire structure coiled on the portion of the liner;
- and
- an additional spool positioned to roll the coiled wire structure coiled on the portion of the liner thereon.
