Abstract: A steering mechanism is used as part of a medical device such as a catheter or an endoscope to allow movement of a steerable distal portion of the catheter or endoscope. The mechanism can include a elongate housing and an actuation system. The elongate housing is adapted to be coupled to the steerable portion of the medical device. The actuation system includes an actuator, a first cam, and a second cam. The actuator can move the first cam between a first position and a second position as the actuator is moved along a first axis (or about a second axis different than the first axis). Movement of the first cam between its first and second positions moves the steerable portion of the medical device along a first plane. The actuator can move the second cam between a first position and a second position as the actuator is moved along the second axis (or about the first axis).

Abstract: This invention generally relates to devices and methods that allow an operator to position an implant into the body of a patient without the need for direct-vision of the operator or the need to hand-guide a needle in order to capture an implant. In one aspect, a multi-arm delivery device includes a receiving arm that releasably holds an implant in place for capture and a clamping arm that includes a needle deployment mechanism for advancing a needle directly to the implant for capture and for retracting the needle with the implant attached to deliver the implant into the desired location. In one embodiment, the needle includes a plurality of retaining slots. In another embodiment, an end portion of the implant is configured to receive a needle into the end portion and at least some of the end portion of the implant is configured to be retained into one or more retaining slots of the needle.

Abstract: In one embodiment, a medical device includes a first arm portion, a second arm portion and a base portion. The first arm portion has an inner surface and an outer surface. The second arm portion has a tissue piercing portion at a distal end, an inner surface and an outer surface. The base portion extends between the first arm portion and the second arm portion. A distance between the inner surface of the first arm portion and the inner surface of the second arm portion defines a depth of penetration into a tissue of a patient.

Abstract: This invention generally relates to devices and methods that allow an operator to deliver a suture and an implant coupled to the suture into the body of a patient without the need for direct-vision of the operator. In one aspect, a medical device includes a receiving arm that releasably holds an implant or suture in place for capture and a clamping arm that includes a needle deployment mechanism for advancing a needle directly to the implant for capture and for retracting the needle with the implant attached to deliver the implant into the desired location. The receiving arm includes a cavity with inner walls that are angled to direct the needle through the opening after the advancing needle pierces and goes through tissue of the patient. The angled walls facilitate movement of the needle into a position within the cavity where the implant gets engaged with the needle.
