Claims8
A suture, comprising:
- a number of unidirectional, pressed in, side features to increase a pullout resistance of the suture along a first direction;
- and
- a distal end protrusion to resist suture pullout from a second direction opposite the first direction.
A suture, comprising:
- a portion of a suture, having a flattened cross section;
- and
- a number of textured side features to increase a pullout resistance of the suture.
An ophthalmic wound visualization device, comprising:
- a substantially transparent portion to place in contact with an eye near an ophthalmic wound;
- a handle to apply pressure to the substantially transparent portion;
- and
- a suture clearance cutaway to facilitate insertion of a suture while the substantially transparent portion is in contact with the eye.
