Abstract
A medical grasper device (10) that is useful for grasping and manipulating a body organ is described. The grasper device is partially inserted into a body cavity and comprises a flexible strap (16) having a distal section (18) that is deployed from a tube (12) to form a partially closed loop (22). A terminal end of the strap has an attachment means, such as aperture (32), that is manipulated by a separate forceps-type device to mate the attachment aperture with a connection means (34) to complete the loop. The closed loop is then adjustable in size to provide for positioning the loop at a desired location around the target body organ to grasp and manipulate the body organ. Various embodiments show the connection means provided on either the tube, a drive rod (406) disposed in a movable relationship inside the tube and on the strap itself, and connectable to the strap attachment means to close the loop.
