Abstract
A capsular tension ring inserter (10) and method includes a cannula (54) adapted to house a capsular tension ring (CTR) (26) having a leading eyelet (32), a hook element (56) disposed within the cannula (54) that engages and moves the CTR (26) during deployment, and a suture (28) placed on the leading eyelet (32) and fed back through the cannula (54) to allow a user to control insertion of the CTR (26) into a capsular bag (42) of an eye (40) by pulling on the suture (28) during insertion of the CTR (26).
Claims24
A capsular tension ring inserter (10) comprising:
- a cannula (54);
- a capsular tension ring (CTR) (26) disposed within said cannula (54) and having a leading eyelet (32);
- an element (56) disposed within said cannula (54) that engages and moves said CTR (26) during deployment;
- and
- a suture (28) placed on said leading eyelet (32) and fed back through said cannula (54) to allow a user to control said CTR (26) by pulling on said suture (28) for controlled deployment of said CTR (26).
A capsular tension ring inserter (10) comprising:
- a capsular tension ring (CTR) (26) having a leading eyelet (32);
- a cannula (54) housing said CTR (26);
- an element (56) disposed within said cannula (54) that engages and moves said CTR (26) during deployment;
- and
- a pre-loaded suture (28) on said leading eyelet (32) and said cannula (54) to allow a user to control insertion of said CTR (26) into a capsular bag (42) of an eye (40) by pulling on said suture (28) during insertion of said CTR (26).
A method of operating a capsular tension ring inserter (10), said method comprising the steps of:
- providing a capsular tension ring (CTR) inserter (10) including a cannula (54) that houses a capsular tension ring (CTR) (26) having a leading eyelet (32) and an element (56) disposed within the cannula (54) that engages and moves the CTR (26) during deployment;
- placing a suture (28) on the leading eyelet (32);
- moving the CTR (26) to a partially deployed position;
- and
- controlling the leading eyelet (32) with the suture (28) during insertion of the CTR (26) in a capsular bag (42) of an eye (40) by allowing a user to pull on the suture (28) during insertion of the CTR (26).
A method of pre-loading a capsular tension ring (CTR) inserter (10) with a suture (28) where the CTR inserter has a cannula (54) housing a capsular tension ring (CTR) (26), said method comprising the steps of:
- moving the CTR (26) to a partially deployed position outside of the cannula with at least a leading eyelet (32) of the CTR positioned outside of the cannula;
- inserting the suture (28) through the leading eyelet (32) of the CTR (26) while the CTR is partially deployed,
- feeding the suture (28) through at least a port or an opening in the cannula,
- retracting the CTR (26) within the CTR inserter (10) to define a pre-loaded condition with the suture (28) remaining looped around the leading eyelet (32) of the CTR (26) and remaining through the port or opening when in the pre-loaded condition to allow a user to control the leading eyelet of the CTR (26) during deployment of the CTR (26).
