Abstract
Methods, systems and apparatuses for soft tissue repair including a device for anchoring sutured tissue to a bone are disclosed. According to one example, the device can include a body and a member. The body can have a wall with an outer surface thereof configured to engage the bone of a patient. The body can define an inner passage extending generally from a proximal end thereof to a distal end thereof. The wall can have a first side having a first size that differs from a second size of a second side of the wall. The member can be configured to be disposed within the body and can be moveable along the inner passage relative to the body between a first position and a second position. The member can be configured with an eyelet to receive and pass a suture through the member when the member is in the first position.
Claims18
A device for anchoring sutured tissue to a bone, the device comprising:
- a body having a wall with an outer surface thereof configured to engage a bone of a patient, the body defining an inner passage extending generally from a proximal end thereof to a distal end thereof, the wall having a rectangular cross-sectional shape so as to have a first side with a first size that differs from a second size of a second side of the wall, wherein the body comprises an expandable shell with deformable wing projections along at least the first side and has a slit formed by the wall thereof along the second side, the slit extending an entirety of a proximal-distal length of the second side of the wall;
- and
- a member configured to be disposed within the body and moveable along the inner passage relative to the body between a first position and a second position, wherein the member is configured with an eyelet to receive and pass a suture through the member at a position distal of the body when the member is in the first position, wherein the member has a protrusion from an outer surface thereof that generally aligns with the proximal-distal extending slit, the member being configured to facilitate expansion of the body when the member is in the second position relative to the first position, and wherein the eyelet is positioned proximal of the body when the member is in the second position.
A system for anchoring a sutured tissue to a bone, the system comprising:
- one or more sutures;
- an outer body having a wall with an outer surface configured to engage a bone of a patient, the body having an inner passage extending generally from a proximal end thereof to a distal end thereof, the wall having a rectangular cross-sectional shape so as to have a first side with a first size that differs from a second size of a second side of the wall, wherein the body comprises an expandable shell and has a slit formed by the wall thereof along the second side, the slit extending an entirety of a proximal-distal length of the second side of the wall;
- an inner bullet configured to be disposed within the body and moveable along the inner passage relative to the body from a first position to a second position, wherein the bullet has a protrusion from an outer surface thereof that generally aligns with the proximal-distal extending slit, the bullet being configured to facilitate expansion of the body when the bullet is in the second position relative to the first position;
- and
- a surgical tool configured to actuate movement of the bullet relative to the body between the first position and the second position via a deployment pin that is coupleable to the bullet, wherein in the first position the deployment pin extends through the body via the inner passage and has an eyelet configured to capture the one or more sutures distal of the body, and wherein in the second position the deployment pin is configured to be detachable from the bullet and removable from the body leaving the bullet positioned within the body and the one or more sutures captured between the bullet and the body.
