Abstract
Various aspects of the present disclosure are directed toward medical device deployment apparatuses, systems, and methods that include a constraint configured to releasably constrain the medical device. The constraint may be unraveled at different rates.
Claims24
A medical device deployment apparatus, the apparatus comprising:
- a constraint configured to releasably constrain the medical device and including a plurality of interlocking strands farming a first knot row configured to unravel at a first deployment rate, a second knot row configured to unravel at a second deployment rate that is different from the first deployment rate, and a third knot row spaced from the first and second knot rows;
- wherein disrupting a strand of the first knot row initiates unraveling of at least a portion of the constraint at the first deployment rate, disrupting a strand of the second knot row initiates unravelling of at least a portion of the constraint at the second deployment rate, and disrupting a strand of the third knot row initiates unraveling of at least a portion of the constraint at a third deployment rate that is different that the first and second deployment rates;
- and
- wherein a deployment ratio between the first knot row and the second knot row is different than a deployment ratio between the second knot row and the third knot row.

A medical device deployment apparatus, the apparatus comprising:
- a constraint configured to releasably constrain the medical device and including a plurality of interlocking strands forming a first knot row configured to unravel at a first deployment rate and a second knot row configured to unravel at a second deployment rate that is different from the first deployment rate;
- wherein disrupting a strand of the first knot row initiates unraveling of at least a portion of the constraint at the first deployment rate, disrupting a strand of the second knot row initiates unravelling of at least a portion of the constraint at the second deployment rate;
- wherein a pattern formed by the plurality of interlocking strands differs along a length of the constraint;
- and
- wherein the plurality of interlocking strands form a plurality of knot rows, including the first knot row and the second knot row, that increases or decreases in number along the length of the constraint.

- a constraint configured to releasably constrain the medical device and including a plurality of interlocking strands forming a first knot row configured to unravel at a first deployment rate and a second knot row configured to unravel at a second deployment rate that is different from the first deployment rate;
- wherein disrupting a strand of the first knot row initiates unraveling of at least a portion of the constraint at the first deployment rate, disrupting a strand of the second knot row initiates unravelling of at least a portion of the constraint at the second deployment rate;
- wherein a pattern formed by the plurality of interlocking strands differs along a length of the constraint;
- and
- wherein the plurality of interlocking strands form a plurality of knot rows, including the first knot row and the second knot row, and interactions between the plurality of interlocking strands differs along the length of the constraint.

A method of using a medical device deployment apparatus, the method comprising:
- providing a constraint including a first knot row, a second knot row, and a third knot row;
- disrupting a strand of the first knot row to initiate unravelling of at least a portion of the constraint at a first deployment rate;
- disrupting a strand of the second knot row to initiate unravelling of at least a portion of the constraint at a second deployment rate that is greater than the first deployment rate;
- disrupting a strand of the third knot row to initiate unravelling of at least a portion of the constraint at a third deployment rate that is different than the first and second deployment rates;
- and
- wherein a deployment ratio between the first knot row and the second knot row is different than a deployment ratio between the second knot row and the third knot row.
