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.

Devices and methods for suture placement

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 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 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 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 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.
