Abstract

Medical devices having a platform and an arm movable between a collapsed position and an expanded position. In some embodiments, the platform comprises at least one of a magnetically-attractive material and a material capable of being magnetically-charged. Methods of use.

1 . A medical device comprising:
 a platform comprising at least one of a magnetically-attractive material and a material capable of being magnetically-charged;   an arm pivotally coupled to the platform such that the arm is rotatable around a rotational axis between a collapsed position and an expanded position; and   a detent mechanism configured to adjustably fix the position of the arm relative to the platform.   
     
     
         2 . The medical device of  claim 1 , where the detent mechanism comprises a detent member coupled to one of the platform and the arm such that the detent member is biased in a bias direction toward the other of the platform and the arm. 
     
     
         3 . The medical device of  claim 2 , where the detent mechanism further comprises a spring configured to bias the detent member in the bias direction. 
     
     
         4 . The medical device of  claim 2 , where the detent member comprises a ball. 
     
     
         5 . The medical device of  claim 1 , where the platform comprises a resilient portion biased toward the arm, and the detent member comprises a protrusion extending from the resilient portion of the platform such that the detent member is biased in a bias direction toward the other of the platform and the arm. 
     
     
         6 . The medical device of  claim 1 , where the other of the platform and the arm comprises one or more indentations configured to receive the detent member. 
     
     
         7 . The medical device of  claim 6 , where the one or more indentations comprise a first indentation corresponding to the collapsed position of the arm and a second indentation corresponding to the expanded position of the arm. 
     
     
         8 . The medical device of  claim 7 , where the one or more indentations comprise a third indentation corresponding to at least one position of the arm between the collapsed position and the expanded position. 
     
     
         9 . The medical device of  claim 6 , where at least one of the one or more indentations comprises a curved surface. 
     
     
         10 . The medical device of  claim 9 , where at least one of the one or more indentations comprises a substantially semispherical surface. 
     
     
         11 . The medical device of  claim 1 , where the detent member of the detent mechanism is coupled to the platform, and the arm comprises the indentation. 
     
     
         12 . The medical device of  claim 1 , where the detent member of the detent mechanism is coupled to the arm, and the platform comprises the indentation. 
     
     
         13 . The medical device of  claim 1 , where the detent mechanism is configured such that the detent member can move linearly along a bias axis between an extended position and a collapsed position. 
     
     
         14 . The medical device of  claim 13 , where the bias axis is substantially perpendicular to the rotational axis. 
     
     
         15 . The medical device of  claim 13 , where the arm is rotatable in a rotational plane, and the bias axis is substantially parallel to the rotational plane. 
     
     
         16 . The medical device of  claim 13 , where the arm is rotatable in a rotational plane, and the bias axis is substantially perpendicular to the rotational plane.
