Abstract
Medical devices for attaching suture to tissue and that provides reliable and complete closure of perforations and increases the versatility of the device for various other procedures. Embodiments of the medicals devices include a tissue anchor having a crossbar with opposing ends and structure for slidably receiving a suture.
Claims19
A tissue anchor for connecting a suture to tissue, the tissue anchor comprising:
- a crossbar having first and second opposing ends and defining a longitudinal axis, the crossbar being defined by a tubular wall having an aperture between the first and second ends;
- and
- a strand having first and second opposing ends connected to the first and second opposing ends of the crossbar, respectively, the strand making a revolution to define a loop, the strand and its loop projecting through the aperture and away from the longitudinal axis, the loop sized to slidably receive the suture therein.
A tissue anchor for connecting a suture to tissue, the tissue anchor comprising:
- a crossbar having first and second opposing ends and defining a longitudinal axis, the cross bar being defined by a tubular wall having first and second apertures between the first and second ends, the first and second apertures being longitudinally spaced apart;
- and
- a flexible suture having first and second opposing ends connected to the first and second opposing ends of the crossbar, respectively, the suture extending through the first and second apertures and projecting away from the crossbar between the first and second apertures to define a loop between the suture and the crossbar, the loop sized to slidably receive the suture therein.
A tissue anchor for connecting a suture to tissue, the tissue anchor comprising:
- a crossbar having first and second opposing ends and defining a longitudinal axis;
- and
- a flange connected to the crossbar between the first and second ends and extending away from the longitudinal axis, the flange having a thickness less than a diameter of the crossbar, the flange defining a hole sized to slidably receive the suture therein.
