Abstract
Various aspects of the present disclosure are directed toward medical device deployment apparatuses, systems, and methods. The apparatuses, systems, and methods may include at least one first constraining fiber arranged as a series of multiple loops to form a warp knit surrounding the medical device in a constrained configuration and at least one second constraining fiber arranged with the at least one first constraining fiber having at least one loop arranged in a non-warp knit pattern.
Claims20
A medical device deployment apparatus, the apparatus comprising:
- a medical device;
- at least one first constraining fiber arranged as a series of multiple loops to form a warp knit surrounding the medical device in a constrained configuration, the warp knit being configured to separate and be removed to deploy the medical device;
- and
- at least one second constraining fiber arranged with the at least one first constraining fiber in the warp knit, the at least one second constraining fiber having at least one loop arranged in a non-warp knit pattern including a chain-link stitch.
A method of deploying constrained medical device, the method comprising:
- arranging the medical device in a constraint, the constraint including at least one first constraining fiber arranged as a series of multiple loops to form a warp knit surrounding the medical device in a constrained configuration, the warp knit being configured to separate and be removed to deploy the medical device and at least one second constraining fiber arranged with the at least one first constraining fiber, the at least one second constraining fiber having at least one loop arranged in a non-warp knit pattern including a chain-link stitch;
- and
- unravelling the constraint by applying tension to an end of the at least one second constraining fiber.
A medical device deployment apparatus, the apparatus comprising:
- an implantable medical device;
- a constraint configured to releasably constrain the implantable medical device in a constrained configuration, the constraint including:
- a first row of knots formed by a first constraining fiber interwoven with a second constraining fiber to form a warp knit surrounding the medical device in the constrained configuration, and
- a second row of knots formed by the second constraining fiber interwoven with a third constraining fiber to form a non-warp knit, including a chain-link stitch surrounding the medical device in the constrained configuration;
- and
- a deployment line coupled to the constraint and configured to unknit the constraint and deploy the implantable medical device from the constrained configuration.
