Abstract:
1. A handle for a suture delivery device, comprising: a handle body configured to be received in a human hand; a jaw operating arm pivotably coupled to the handle body at a first end and biased away from the handle body; a needle drive shaft controlling arm pivotably coupled to the handle body and biased away from the handle body; a position retention arm pivotably coupled to the needle drive shaft controlling arm and slideably coupled to the handle body; wherein the position retention arm includes at least one slot receiving a pin extending from the handle body; and wherein the at least one slot includes a first slot section that facilitates movement of a needle drive shaft generally along a longitudinal axis of the needle drive shaft and a second slot section of the at least one slot that facilitates movement of the needle drive shaft generally along the longitudinal axis; wherein the first and second slot sections of the at least one slot are separated by a retention slot section and a spring arm that contacts the pin and extends generally parallel to the first slot section and generally parallel to the retention slot section, whereby the spring arm retains the pin in the retention slot section and prevents the pin from inadvertently passing from the second slot section to the first slot section; wherein the first slot section is positioned oblique to the retention slot section; wherein the retention slot section is positioned oblique to the second slot section, whereby a needle is retained within the suture delivery device when the pin is retained in the retention slot section; and wherein the first slot section is defined in part by the spring arm and in part by the position retention arm, and the second slot section is defined by the position retention arm.
