         3 . The medical device of  claim 1 , wherein each of the plurality of wire locking features includes a slot that is aligned with an axis and a well, wherein the slot includes a tapered wall that extends towards the slot axis and the well. 
     
     
         4 . The medical device of  claim 1 , further comprising a side wall protrusion extending from the first surface, the side wall protrusion having an outside surface and an inside surface configured to receive the wire. 
     
     
         5 . The medical device of  claim 4 , wherein the side wall protrusion extends towards the third surface. 
     
     
         6 . The medical device of  claim 1 , further comprising a wire contacting feature extending from the first surface, the wire contacting feature defining a wall, wherein the side wall protrusion inside surface and the wall define a channel between the first surface and the third surface. 
     
     
         7 . The medical device of  claim 6 , wherein the channel extends along a center axis that is substantially perpendicular to a center axis that the opening extends along. 
     
     
         8 . The medical device of  claim 1 , wherein the medical device comprises a cap through which the wire is extendible. 
     
     
         9 . The medical device of  claim 8 , wherein the cap comprises an opening and the body comprises a barb that is configured to engage the cap opening to connect the cap and the body. 
     
     
         10 . The medical device of  claim 1 , wherein the plurality of wire locking features are arranged two at the upper wire guiding portion and one at the lower wire guiding portion. 
     
     
         11 . A medical device comprising:
 a body defining an opening through which a wire is extendible;   a wire guiding portion coupled with the body, the wire guiding portion configured to guide the wire along with an axis; and   at least two wire locking features configured to hook the wire at the wire guiding portion, the at least two wire locking features each comprising a slot extending in opposite direction along a slot axis substantially perpendicular to the axis.   
     
     
         12 . The medical device of  claim 11 , wherein the at least two wire locking features each comprise a well and the slot includes a tapered wall that extends towards the slot axis and the well. 
     
     
         13 . The medical device of  claim 11 , wherein at least one of the at least two wire locking features is configured to provide a tactile feedback of the wire being engaged in each of the at least two wire locking features. 
     
     
         14 . The medical device of  claim 11 , the wire guiding portion comprising:
 an upper wire guiding portion having a first surface and a second surface opposite the first surface;   a lower wire guiding portion coupled with the body, the lower wire guiding portion having a first surface and a second surface opposite to the lower wire guiding portion first surface, wherein the lower wire guiding portion first surface faces the upper wire guiding portion second surface.   
     
     
         15 . The medical device of  claim 14 , wherein a first of the at least two wire locking features is disposed at the upper wire guiding portion and a second of the at least two wire locking features is disposed on the lower guiding portion. 
     
     
         16 . The medical device of  claim 15 , wherein the first of the at least two wire locking features is disposed at the upper wire guiding portion second surface and the second of the at least two wire locking features is disposed on the lower wire guiding portion second surface. 
     
     
         17 . A wire guide for guiding a wire, the wire guide comprising:
 an upper wire guiding portion having a first surface and a second surface opposite to the first surface;   a lower wire guiding portion coupled with the body, the lower wire guiding portion having a first surface and a second surface opposite the lower wire guiding portion first surface, wherein the lower wire guiding portion first faces the upper wire guiding portion second surface; and   a plurality of wire locking features, wherein a first wire locking feature of the plurality of locking features is disposed on the upper wire guiding portion second surface and a second wire locking feature of the plurality of locking features is disposed on the lower wire guiding portion second surface.   
     
     
         18 . The wire guide of  claim 17 , wherein each of the plurality of wire locking features includes a slot that is aligned with an axis and a well, wherein the slot includes a tapered wall that extends towards the slot axis and the well. 
     
     
         19 . The wire guide of  claim 17 , wherein at least one of the plurality of wire locking features is configured to provide an audible or haptic indication in response to a guidewire being placed in contact therewith during insertion of the guidewire into the channel.
