The onset of spontaneous abortion or premature labor of a pregnant human female is continuously monitored, potentially for periods of several months and longer, by a real-time transit-time ultrasonic monitor of the dilatation and/or effacement of the cervix os, preferably by a computerized ambulatory monitor. The preferred computerized monitor sounds an alarm upon the detection of variably present conditions, normally the compound conditions of five or more 10% cyclical variations in the dilatation or effacement of the cervix os within a period of one hour, coupled with a greater than 1 centimeter increase over baseline of either dilatation or effacement, which compound conditions normally indicate the early onset of labor. The monitor connects to an infusion pump, likewise preferably ambulatory, for directing and controlling the infusion of one or more tocolytic, labor-preventing, drugs if labor continues. In this manner patient activity and patient chemistry can be early detected, early alarmed and early beneficially altered even before it is possible to receive the diagnosis or treatment of a physician of other health care provider.

The invention provides a method of fundoplication of the stomach to the esophagus comprising introducing an esophageal manipulator (72) into the stomach lumen (10), maneuvering the manipulator within the lumen so as to create an intussusception (48) of the esophagus (14) into the stomach, introducing a stapler (68) to the lumen of the stomach, and stapling the intussuscepted esophagus to the stomach operation of the stapler is from within the lumen of the stomach. The invention also provides a medical or surgical stapler comprising an elongated body (80) having a passageway (70) which is adapted to receive a medical component such as a forceps (72) or fluid.

Systems and methods for auto-anastomosing a region occupying one or more hollow viscera of the body are disclosed. The system includes a first magnetic member configured to be delivered to a location in the body adjacent the region. A second magnetic member is configured to be located adjacent the region opposite from the first magnetic member such that said region is disposed in between the first magnetic member and the second magnetic member. The first and second magnetic members are configured to generate an attractive force to compress tissue in the region between them so that the tissue in the region necroses as a result of the compressive force such that tissue surrounding the necrosed tissue heals together to form an anastomosis. The anstomosis may connect a fistula between two internal viscera or viscera segments, or create a stoma from a viscera to an external surface of the body.

A system for auto-anastomosing a region of the body using magnetic members that may be individually delivered to different locations in the body. The magnetic members have a polar alignment that generates an attractive force to compress tissue in the region between them. The tissue in the region necroses as a result of the compressive force such that tissue surrounding the necrosed tissue heals together to form an anastomosis. A cutting member may be coupled to either the first or second magnetic member to create a temporary opening in the tissue.
