Abstract
A tissue anchor comprising a body having a longitudinal axis, a proximal end with one set of dimensions and a projected surface area, a distal end with a second set of dimensions and a projected surface area where the respective dimensions of the first and second ends are not identical and the projected areas are substantially the same. The tissue anchor may further have a fixing member to attach the anchor and one or more tissues together or to attach the other structures to tissue.
Claims15
A tissue anchor, comprising:
- a body having a longitudinal axis, a proximal end, a distal end, and a longitudinal suture passageway that defines a first suture exit near the distal end and a second suture exit near the proximal end, and comprising a bridge that extends between the first suture exit and the second suture exit, the bridge having a center point defined as the point midway between the first suture exit and the second suture exit, the body being divided into a first portion distal of the center point and a second portion proximal of the center point,
- wherein the length of the first portion and the length of the second portion are not equal, and the projected surface area of the first portion is substantially equal to the projected surface area of the second portion.
A tissue anchor device, comprising:
- an elongated body extending along a longitudinal axis, the body comprising:
- a distal end and a proximal end, the distal end comprising a tapered portion having a tissue penetrating tip,
- a distal channel extending at least through a portion of the tapered portion, the distal channel defining a first suture exit approximate the distal end,
- a proximal bore that communicates with the channel, the proximal bore defining a second suture exit approximate the proximal end,
- a bridge extending between the first suture exit and the second suture exit, the bridge having a center point defined as the point midway between the first suture exit and the second suture exit, the body being divided into a first portion distal of the center point and a second portion proximal of the center point, wherein the length of the first portion and the length of the second portion are unequal and the projected surface area of the first portion and the projected surface area of the second portion are substantially equal;
- and
- an elongate anchor driver having a distal end configured to releasably engage the proximal bore;
- and
- a suture configured to pass through the channel and the bore.
A tissue anchor device, comprising:
- an elongated body extending along a longitudinal axis, the body comprising a projected surface area having a centroid and a centroid plane that is perpendicular to the longitudinal axis and intersects the centroid, the centroid plane dividing the body into a first portion and a second portion,
- the first portion comprising a first projected surface area and a first dimension, the second portion comprising a second projected surface area and a second dimension, the first projected surface area and the second projected surface area being substantially equal and the first dimension and the second dimension being substantially unequal;
- the first portion comprising a tapered portion having a sharpened tip and a channel extending at least through a portion of the tapered portion,
- the second portion comprising a substantially cylindrical configuration and a bore communicating with the channel;
- an elongate anchor driver having an end configured to releasably engage the bore;
- and
- a suture configured to pass through the channel and the bore.
A tissue anchor device, comprising a body having a projected surface area having a centroid, the body having a longitudinal axis and a centroid plane that is perpendicular to the longitudinal axis and intersects the centroid, the centroid plane dividing the body into a first portion and a second portion, the first portion having a first projected surface area and a first dimension, the second portion having a second projected surface area and a second dimension, the first projected surface area and the second projected surface area being substantially equal and the first dimension and the second dimension being substantially unequal.
