Abstract
Synthetic chord devices and methods for using the same for connecting tissues are provided. Aspects of the synthetic chord devices include a first flexible connector having first and second ends. Located at the first end is an attachment element that includes a piercing member coupled to a securing member, wherein the securing member transitions from a linear to a planar configuration upon separation of the piercing member from the attachment element. A reinforcing element is located at the second end. The devices and methods of the invention find use in a variety of applications, such as cardiac valve, e.g., mitral valve repair; or tissue closure.
Claims20
A synthetic chord consisting of:
- (a) a first flexible connector comprising a filament having first end and a second end, wherein the filament comprises a polymeric material;
- (b) an attachment element located at the first end of the filament and comprising a tissue piercing member and a securing member, wherein the securing member comprises a shape memory material and the securing member transitions from a linear to a planar configuration upon separation of the tissue piercing member from the attachment element;
- and
- (c) a reinforcing element located at a second end of the filament.
A synthetic chord consisting of:
- (a) a first flexible connector comprising a filament having first end and a second end, wherein the filament comprises a polymeric material;
- (b) an attachment element located at the first end of the filament and comprising a tissue piercing member and a securing member, wherein the securing member comprises a bar and the securing member transitions from a linear to a planar configuration upon separation of the tissue piercing member from the attachment element;
- and
- (c) a reinforcing element located at a second end of the filament.
A kit comprising:
- a set of two or more synthetic chord devices, each device of said set comprising:
- (a) a first flexible connector comprising a filament having a first end and a second end, wherein the filament comprises a polymeric material;
- (b) an attachment element located at a first end of the filament and comprising a tissue piercing member and a securing member located at the first end of the flexible connector, wherein the securing member either comprises a shape memory material or comprises a bar, and wherein the securing member transitions from a linear to a planar configuration upon separation of the tissue piercing member from the attachment element;
- and
- (c) a reinforcing element located at a second end of the filament.
