Abstract
A medical grasper device (10) that is useful for holding and manipulating a body organ is described. The grasper device is partially inserted into a body cavity and comprises a flexible strap (14) having a distal section (18) that is deployed from a tube (12) to form a partial closed loop (2). A terminal end of the strap has an aperture (42) that is manipulated by a separate forceps-type device to mate with a connection means (56) provided on the grasper device 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 hold and manipulate the body organ. At such time as the grasper device is no longer needed in the surgical procedure, the strap is either removed from the connection means with the aforementioned forceps-type device or is cut by a separate cutting means to release the loop from the body organ and the grasper device is removed from the body cavity.
