Patent number: 11162911Abstract: A system, method, and computer program product for verifying a purported composition of material in a solid metal object based on heat transfer characteristics. Embodiments include determining, using a group of temperature sensors included in a heat sink, a heat transfer profile for the heat sink when connected to the solid metal object. One or more embodiments include comparing the heat transfer profile for the solid metal object to a baseline heat transfer profile determined based on dimensions of the solid metal object and the purported composition. One or more embodiments include determining, based on the comparing, a difference between the heat transfer profile and the baseline heat transfer profile.

Publication number: 20070261699Abstract: Systems and methods of visibly marking a reproductive tract, e.g., at least one ostium of the Fallopian tubes accessed transvaginally and transcervically, to indicate delivery of an occlusion device into the corresponding at least one Fallopian tube to effect contraception are disclosed. Marking is effected by delivery of a dye that stains the ostium and/or extension of the marking member from the delivered occlusion device into view in the uterine cavity or ostium. A catheter (or catheters) preferably introduced through a hysteroscope that illuminates and provides visualization of the uterine cavity and the ostia of the Fallopian tubes is employed to insert each contracted, stent-like, occluding device into each Fallopian tube and to mechanically expand or release to self-expand the occluding device.Type: ApplicationFiled: May 11, 2006Publication date: November 15, 2007Inventors: Jeffrey Callister, William Tremulis

Publication number: 20050288551Abstract: The invention is directed to an endoscopic assembly having an endoscope, particularly a flexible hysteroscope and an outer sheath disposed about a length of the shaft of the hysteroscope which has an expandable member such as an inflatable balloon for sealing the assembly within a body lumen or cavity. Specifically, the endoscope assembly is configured for delivery of an occlusive contraceptive member to the patient's fallopian tube. The invention is also directed to an endoscope having a driving member for movement of a medical device within the working lumen of an endoscope. In one embodiment the driving member is a friction wheel which engages an elongated medical device disposed within the working channel of the endoscope to effect longitudinal movement of the medical device.Type: ApplicationFiled: April 27, 2005Publication date: December 29, 2005Inventors: Jeffrey Callister, William Tremulis, Laura Kemp, Paul Stull

Publication number: 20050081862Abstract: A device and method of using the device for contraception or sterilization and particularly for reversible contraception by occluding a reproductive lumen to prevent the passage of reproductive cells through the lumen for a desired period of time until the patient wishes to become fertile again and then be reopened. The occluding member preferably comprises a tubular framework formed from a shape memory material configured to be implanted in a reproductive lumen. The occluding member is implanted within a body lumen, secured to the wall of the reproductive lumen and then collapsed to collapse the wall and occlude the lumen. Alternatively, the occluding member may be collapsed upon a solid plug. The closure of the reproductive lumen may be reversed by introducing a balloon catheter and by a series of inflations of the balloon reexpanding the collapsed occluding member or by removing the plug.Type: ApplicationFiled: October 25, 2004Publication date: April 21, 2005Inventors: Jeffrey Callister, William Tremulis, Denise Harges
