Abstract

A prosthesis device can include a socket or a kit for forming a socket having a lanyard suspension system. In one example, the lanyard suspension system includes a tightening device having a housing, and tightening the lanyard gathers a tensioning line portion of the lanyard into an interior of the housing.

Claims

exact text as granted — not AI-modified

         13 . The suspension system of  claim 1 , further comprising a diverter configured to redirect the tensioning line from a first direction in which the tensioning line enters the diverter to a second direction that is different from the first direction in which the tensioning line exits the diverter. 
     
     
         14 . (canceled) 
     
     
         15 . The suspension system of  claim 13 , further comprising a conduit coupled to the diverter, the conduit defining a duct through which the tensioning line extends. 
     
     
         16 . (canceled) 
     
     
         17 . The suspension system of  claim 1 , further comprising a conduit that defines a duct through which the tensioning line extends. 
     
     
         18 . (canceled) 
     
     
         19 . (canceled) 
     
     
         20 . The suspension system of  claim 1 , wherein the tightening device comprises a spool within the cavity of the housing, the spool being configured to gather the tensioning line. 
     
     
         21 - 25 . (canceled) 
     
     
         26 . The suspension system of  claim 1 , further comprising a receptacle configured to receive at least a portion of the connector therein. 
     
     
         27 . The suspension system of  claim 26 , wherein the connector is configured to form a first fluid-tight seal with a sidewall of the receptacle. 
     
     
         28 . (canceled) 
     
     
         29 . The suspension system of  claim 27 , wherein the connector is further configured to form a second fluid-tight seal with a portion of the liner, and wherein the first and second fluid-tight seals are configured to inhibit or prevent air from passing through the suspension system during use of the socket. 
     
     
         30 - 37 . (canceled) 
     
     
         38 . A kit for use in the manufacture of a socket for a prosthetic device, the kit comprising:
 a lanyard that comprises a tensioning line;   a tightening mechanism that comprises an actuator and a housing that defines a cavity; and   one or more of (i) instructions for coupling the lanyard and the tightening mechanism with a socket for a prosthetic device or (ii) information usable to access the instructions for coupling the lanyard and the tightening mechanism with the socket for a prosthetic device, the instructions comprising directions to:   couple the housing to the socket; and   couple the lanyard with the tightening mechanism such that actuation of the actuator causes a portion of the tensioning line to gather into the cavity of the housing.   
     
     
         39 . The kit of  claim 38 , further comprising a base, wherein the instructions further comprise directions to secure the base to the socket, and wherein said coupling of the housing to the socket comprises attaching the housing to the base. 
     
     
         40 - 42 . (canceled) 
     
     
         43 . The kit of  claim 38 , wherein the tightening mechanism further comprises a spool and a cover, and wherein the instructions further comprise directions to:
 couple the spool with the tensioning line;   situate the spool within the cavity of the housing; and   close the cavity via the cover.   
     
     
         44 . (canceled) 
     
     
         45 . The kit of  claim 38 , wherein the tightening mechanism further comprises a base, and wherein the housing is configured to be selectively coupled to the base and selectively decoupled from the base. 
     
     
         46 . The kit of  claim 38 , wherein the instructions further comprise directions to:
 form a guide path of which at least a portion extends through a wall of the socket; and   thread the tensioning line through said at least a portion of the guide path that extends through the wall of the socket.

         49 . The kit of  claim 38 , further comprising a diverter configured to redirect the tensioning line from a first direction in which the tensioning line enters the diverter to a second direction that is different from the first direction in which the tensioning line exits the diverter. 
     
     
         50 - 54 . (canceled) 
     
     
         55 . The kit of  claim 38 , further comprising
