Publication number: 20080154256Abstract: A medical device and procedure is described for sterilizing a female. A two-part procedure includes an immediate sterilization part and a permanent sterilization part. The immediate sterilization part provides immediate sterility that endures at least until the permanent effects of a tubal occlusion procedure provide permanent sterility.Type: ApplicationFiled: December 21, 2006Publication date: June 26, 2008Applicant: CYTYC CORPORATIONInventors: F. Mark Payne, Russel M. Sampson

Publication number: 20080071257Abstract: A method for tissue ablation is described. An RF applicator including an electrode carrier with one or more bipolar electrodes thereon is positioned at a target tissue site for tissue ablation. A current at an initial current level is passed through the one or more bipolar electrodes to the target tissue site to apply an initial power density to destroy tissue for an initial time period. A vacuum source in fluid communication with the RF applicator is employed to remove moisture generated during ablation away from the target tissue site. After the initial time period, the power density is ramped up by increasing the current passed through the one or more bipolar electrodes to the target tissue site for a second time period.Type: ApplicationFiled: September 18, 2006Publication date: March 20, 2008Applicant: Cytyc CorporationInventors: Robert Kotmel, Russel M. Sampson, Scott Dennis Taylor

Publication number: 20080071269Abstract: A medical device and procedure is described which can be used for occluding a fallopian tube. In one implementation, the apparatus includes an elongate member, an electrode carrier and one or more conductors. The elongate member has a lumen operable to couple to a vacuum source and draw moisture way from one or more electrodes included in the electrode carrier, and a lumen configured to receive a hysteroscope. The electrode carrier includes one or more bipolar electrodes and can to couple to a radio frequency energy generator. The one or more conductors connect to a controller operable to control the delivery of radio frequency energy to the one or more bipolar electrodes. The elongate member is a substantially rigid member configured with a curve to facilitate advancement of the distal end transcervically through a uterus and into a region of a tubal ostium of a fallopian tube to be occluded.Type: ApplicationFiled: September 18, 2006Publication date: March 20, 2008Applicant: Cytyc CorporationInventors: Estela H. Hilario, Russel M. Sampson, Robert Kotmel

Patent number: 7192430Abstract: Apparatuses and methods for removing solid tissue from beneath a tissue surface are described. The methods rely on positioning an energy conductive element at a target site beneath the tissue surface and energizing the element so that it can vaporize tissue. The element is then moved in a pattern which provides the desired tissue removal geometry, such as spherical, ovoid, or cylindrical. Usually, the shaft is moved, typically rotated or reciprocated, and the energy conductive element is moved relative to the shaft, typically by pivoting a rigid element or bowing a flexible element.Type: GrantFiled: August 5, 2003Date of Patent: March 20, 2007Assignee: Cytyc CorporationInventors: Csaba Truckai, Russel M. Sampson, Paul K. Hsei

Patent number: 6869425Abstract: A peristaltic pump is provided with a housing, a pump head in the housing, and a receiving path defined along a housing and pump head for receiving tubing. Two spaced-apart temperature sensors are provided. One temperature sensor is located adjacent the tubing in a heat conduction path along which heat flows between the sensor and the tubing. The other sensor is located outside of the heat conduction path for sensing ambient temperature. The pump operating speed is adjusted as a function of the sensed temperatures. This accommodates the temperature-dependent rate of recovery of the tubing from its peristaltically deformed configuration to its original configuration.Type: GrantFiled: April 3, 2002Date of Patent: March 22, 2005Assignee: Hospira, Inc.Inventors: Kenneth D. Briggs, Dean C. Pryce, Russel M. Sampson

Patent number: 6743184Abstract: A system and method for detecting perforations in a body cavity. In accordance with the method of the invention, a fluid (liquid or gas) is delivered into a body cavity to slightly pressurize the cavity. A pressure sensing system monitors the pressure within the cavity for a predetermined test period. If cavity pressure is not substantially sustained during the test period, the physician is alerted to further assess the cavity for perforations before initiating treatment within the cavity. In a preferred form of the system, a medical treatment system such as an RF ablation system is provided with perforation detection functionality. The system preferably includes a pre-test lockout that prevents RF power delivery unless a perforation detection procedure previously has been performed.Type: GrantFiled: March 27, 2003Date of Patent: June 1, 2004Assignee: NovaceptInventors: Russel M. Sampson, Mike O'Hara, Csaba Truckai, Dean T. Miller

Patent number: 6261262Abstract: A peristaltic pump is provided with a housing, a pump head in the housing, and a receiving path defined along a housing and pump head for receiving tubing. A door is pivotable about an axis between a closed position covering the receiving path and an open position exposing the receiving path. A carrier is provided on the housing for holding an anti-free flow slide clamp on the tubing in the receiving path. The carrier is movable relative to the housing so as to automatically effect closure of the tubing by the slide clamp when the door is opened.Type: GrantFiled: June 12, 1997Date of Patent: July 17, 2001Assignee: Abbott LaboratoriesInventors: Kenneth D.

Patent number: 5868712Abstract: A peristaltic pump is provided with a housing, a pump head in the housing, and a receiving path defined along a housing and pump head for receiving tubing. An air sensor assembly in the pump has a slot for receiving a section of the tubing in the receiving path. A position covering the receiving path and an open position exposing the receiving path. An engaging member is provided for pushing the tubing in the slot. The engaging member is pivotally mounted to the door for rotation about an axis parallel to the door pivot axis. The engaging member has a ram for contacting the tubing. The orientation of the ram relative to the door can change as the ram enters the slot when the door closes so that the tubing is pushed relatively evenly and along a substantially straight line into the slot.Type: GrantFiled: June 12, 1997Date of Patent: February 9, 1999Assignee: Abbott LaboratoriesInventors: Kenneth D.
