The lacrimal implants can comprise an implant body, including first and second portions, extending from a proximal end of the first portion to a distal end of the second portion. The second portion includes a retention projection. The implant body can also include a cavity longitudinally extending from the proximal end of the first portion toward the second portion, wherein the cavity is shaped and sized to receive an insertable actuator, and wherein the retention projection is configured to bias outward or change orientation when the insertable actuator is seated within the cavity.Type: ApplicationFiled: November 26, 2010Publication date: September 27, 2012Applicant: QLT INC.Inventors: Sascha K. Zarins, David J. Scott, David Tholfsen

Patent number: 8247239Abstract: A method for introducing standard gas into a sample vessel is generally disclosed comprising providing a vessel containing a sample gas and a receptacle with a vessel port, such as sampling needle, pressurizing the vessel with a carrier gas, and introducing a volume of standard gas into the flow path of the carrier gas being used to pressurize the vessel when the vessel port of the receptacle is located within the vessel. In some embodiments, a rotary valve is loaded with the standard gas, and the valve is brought into fluid communication with the flow path of the carrier gas when the vessel port is within the vessel.Type: GrantFiled: April 13, 2006Date of Patent: August 21, 2012Assignee: PerkinElmer Health Sciences, Inc.Inventors: Andrew Tipler, Christopher Mazza, David J.

Publication number: 20120191166Abstract: Systems and methods for accurate temperature modification of a patient, or selected regions thereof, including inducing hypothermia. The temperature modification is accomplished using an in-dwelling heat exchange catheter within which a fluid heat exchange medium circulates. A heat exchange cassette attached to the circulatory flow lines of the catheter, the heat exchange cassette being sized to engage a cavity within a control unit. A temperature measurement scheme for obtaining body core temperature is provided, including methods of obtaining and analyzing temperature data to provide feedback to the control unit for use in controlling the heating and cooling of the heat exchange medium so as to heat or cool a patient to a desired target temperature.Type: ApplicationFiled: January 23, 2012Publication date: July 26, 2012Applicant: ZOLL CIRCULATION, INC.Inventors: Jeffrey Callister, Paul M. Stull, Andrew E. Wu, David J. Scott

Patent number: 8177824Abstract: A heat exchange fluid supply system for supplying a heat exchange fluid to an intravascular heat exchange catheter includes a disposable cassette having a bulkhead and an external heat exchanger, and which is configured to operate in combination with a reusable master control unit. The bulkhead includes a reservoir section and a pump section. The reservoir section is provided with a means to monitor the amount of heat exchange fluid that is in the system. The bulkhead provides the mechanism for priming the system with heat exchange fluid from an external source and for circulating fluid to the catheter in a closed circuit. The pump section is configured to allow for pumping of heat exchange fluid at a constant pressure.Type: GrantFiled: July 23, 2007Date of Patent: May 15, 2012Assignee: Zoll Circulation, Inc.Inventors: Timothy R. Machold, Nicole Denise Bloom, Alex T. Roth, David J. Scott, Jose Alejandro, Edward A. Oliver

Publication number: 20110295059Abstract: Implants or systems of implants and methods apply a selected force vector or a selected combination of force vectors within or across the left atrium, which allow mitral valve leaflets to better coapt. The implants or systems of implants and methods make possible rapid deployment, facile endovascular delivery, and full intra-atrial adjustability and retrievability years after implant. The implants or systems of implants and methods also make use of strong fluoroscopic landmarks. The implants or systems of implants and methods make use of an adjustable implant and a fixed length implant. The implants or systems of implants and methods may also utilize an adjustable bridge stop to secure the implant, and the methods of implantation employ various tools.Type: ApplicationFiled: August 15, 2011Publication date: December 1, 2011Applicant: MVRx, INC.Inventors: TIMOTHY R.

Publication number: 20110022136Abstract: Methods and apparatuses for temperature modification of a patient, or selected regions thereof, including an induced state of hypothermia. The temperature modification is accomplished using an in-dwelling heat exchange catheter within which a fluid heat exchange medium circulates. A heat exchange cassette is attached to the circulatory conduits of the catheter, the heat exchange cassette being sized to engage a cavity within a control unit. The control unit includes a heater/cooler device for providing heated or cooled fluid to a heat exchanger in thermal communication with the fluid heat exchange medium circulating to the heat exchange catheter, a user input device, and a processor connected to receive input from various sensors around the body and the system. A temperature control scheme for ramping the body temperature up or down without overshoot is provided.Type: ApplicationFiled: October 4, 2010Publication date: January 27, 2011Applicant: ZOLL CIRCULATION, INC.Inventors: David J. Scott, Ben F. Brian, Lloyd F. Wright, Leo A. Chin, Edward W. Hollmen, Daniel W. Seegars, Mark A. Logan
