An implantable prosthesis including a stem and a stem head. The stem extends along a longitudinal axis from a proximal end portion to a distal end portion of the stem. The stem head is coupled to the proximal end portion of the stem. The stem head is configured to be coupled to a joint component. The stem head includes a side surface and a side surface cleat. The side surface cleat defines a first side surface groove and a second side surface groove. The side surface cleat extends between the first side surface and the second side surface.

The present invention discloses a medical suture and a medical suture device, and belongs to the field of medical instruments. The medical suture comprises: a suture body, the suture body defining a longitudinal center line; and a plurality of pairs of barbs arranged at intervals along a direction of the longitudinal center line, each pair of barbs being symmetrically arranged on opposite sides of the suture body, the barb being provided with a first end connected with the suture body and a second end far away from the suture body, and a ratio of a transverse distance L1 of second ends of each pair of the barbs along a direction perpendicular to the longitudinal center line to a transverse dimension L0 of the suture body perpendicular to the direction of the longitudinal center line ranging from 1.5 to 2.5.

A suturing kit includes a suture and a suture holder for holding the suture. The suture has a first end and a second, opposite, end. The suture holder includes an elongated wall defining a suture receiving passage that is elongated along a longitudinal axis and terminates at a suture exit opening. The suture receiving passage has a width at least twice the diameter of the suture and receives the suture such that the suture is folded over forming a half loop section spaced from the suture exit opening. A first second of the suture extends from the half loop section toward the first end and a second section of the suture extends from the half loop section towards the second end. The first section and the second section of the suture within the suture receiving passage are aligned parallel to the longitudinal axis.

A suturing device includes a curved needle, a suture, an elongate body, an actuator and a curved needle holder. The suture connects with the curved needle. The actuator is operable between a first operating position and a second operating position. The curved needle holder extends away from a distal end portion or is provided as part of the distal end portion of the elongate body. The curved needle holder includes a distal end section having a distal-most tip. The curved needle holder defines a curved needle passage and a distal opening. Movement of the actuator from the first operating position toward the second operating position moves the curved needle with respect to the curved needle holder toward a released condition. The distal end section is configured to allow the curved needle to release from the curved needle holder at a location offset from the distal-most tip.

A suturing kit includes a double-armed suture, at least one suturing device and a suture holding structure. The double-armed suture has a first needle at a first end and a second needle at a second, opposite, end. The at least one suturing device includes a first needle holder configured to receive the first needle in a retracted position, a second needle holder configured to receive the second needle in a retracted position and at least one actuator configured to drive the first needle or the second needle in an advance direction toward a released condition. The suture holding structure holds at least a portion of the suture between the first end and the second end, and the suture holding structure is separate from the at least one suturing device so as not to be inserted into the patient during the surgical procedure.

A suturing device includes an elongate body, an actuator, a needle holder and a knot pusher. The elongate body includes a proximal end portion and a distal end portion. The actuator interacts with the elongate body and is operable between a first operating position and a second operating position. The needle holder extends away from the distal end portion or is provided as part of the distal end portion of the elongate body, and includes a distal end section having a distal-most tip. The needle holder defines a needle passage and a distal opening adjacent the distal-most tip. The knot pusher connects with and extends away from at least one of the elongate body and the needle holder.

A suturing device includes a curved needle, a suture, an elongate body, an actuator and a curved needle holder. The suture connects with the curved needle. The actuator interacts with the elongate body and is operable between a first operating position and a second operating position. The curved needle holder extends away from a distal end portion or is provided as part of the distal end portion of the elongate body. The curved needle holder includes a distal end section having a distal-most tip. The curved needle holder includes an inner surface defining a needle passage for holding the needle and a distal opening. The curved needle has a curved needle radius and the curved needle passage has a curved needle passage radius that is different than the curved needle radius and the curved needle frictionally engages the inner surface when the needle is in a retracted position.

A suturing device includes a needle, a suture, an elongate body, an actuator and a needle holder. The suture connects with the needle. The needle holder extends away from a distal end portion or is provided as part of the distal end portion of the elongate body. The needle holder includes a distal end section having a distal-most tip, and defines a needle passage for holding the needle and a distal opening. At least a portion of the suture extends through the distal opening when the needle is received in the needle passage and the actuator is in a first operating position. At least a portion of the suture extends along the needle passage toward the distal opening between the needle and an inner surface of the needle holder when the needle is received in the needle passage and the actuator is in the first operating position.

A suturing device includes an elongate body, an actuator, and a curved needle holder. The elongate body includes a distal end portion extending along a longitudinal axis. The actuator is operable between a first operating position and a second operating position. The curved needle holder extends away from the distal end portion or is provided as part of the distal end portion of the elongate body. The curved needle holder includes a distal end section having a distal-most tip, and defines a curved needle passage and a distal opening adjacent the distal-most tip. A distance measured parallel with the longitudinal axis between where the curved needle holder begins to curve away from the longitudinal axis to either where the elongate body begins to curve away from the longitudinal axis or where the elongate body connects with a handle can be between about 10 cm to about 20 cm. Also, the distal-most tip can be offset from the longitudinal axis in a direction perpendicular to the longitudinal axis an offset distance less than about 7 mm.

A wound closure system and a method of reducing the size of an open wound are disclosed. A suture line is sutured through body tissue adjacent an open wound, the suture line sutured so as to pass into the body tissue at an entry point and exit at an exit point, the suture line including a plurality of barbs extending outwardly at an acute angle with respect to a surface of the suture line. A biasing member applies a continuous pulling force on the suture line for stretching the body tissue toward the open wound, wherein the biasing member is configured to take up any slack of the suture line during stretching of the body tissue and keep the suture line taut.
