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 constraining fiber configured to form a warp knit surrounding a medical device with a first series of loops forming the warp knit with at least one of the first series of loops including a first portion forming a knot and a second portion arranged in addition to the knot.
Claims17
A method of releasably constraining a medical device, the method comprising:
- forming a warp knit to surround a medical device using at least one constraining fiber, the warp knit being configured to separate and be removed to deploy the medical device and including a first series of loops;
- and
- forming a knot within the warp knit with at least one of the first series of loops including a first portion and a second portion arranged in addition to the knot.
A deployment apparatus, the apparatus comprising:
- an implantable medical device;
- a constraint configured to releasably constraint 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 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 surrounding the medical device in the constrained configuration, the first row of knots including a distal knot formed by a first loop of the first constraining fiber and a second loop of the second constraining fiber with the second loop including a first portion forming the knot and a second portion arranged in addition to the knot.
A medical device deployment apparatus, the apparatus comprising:
- at least one constraining fiber (110) including a first series of loops defining a warp knit surrounding a medical device, the warp knit being configured to separate and be removed to deploy the medical device, wherein the at least one constraining fiber (110) includes a first portion including a first length defining a knot and a second portion including a second length in addition to the first length of the first portion, the second length providing increased friction for unknitting the knot, the medical device deployment apparatus thereby resisting premature deployment of the medical device.
