Patent number: 7206620Abstract: An analyte (e.g., glucose) is tested in a sample (e.g., blood or blood-free interstitial fluid) having both the analyte and other constituents (e.g., protein). The analyte has an absorption peak over a narrow bandwidth at a characteristic wavelength. The other constituents have an absorption over a broad bandwidth. The broad bandwidth includes and is broader than the narrow bandwidth. Radiant energy (e.g., IR radiation) is directed at the sample. The energy has a source bandwidth including the broad bandwidth. The sample absorbs a portion of the energy. A remainder of the energy is available for analysis. The remainder is analyzed by filtering the remainder into an analyte portion and a reference portion. The analyte portion contains substantially only the narrow bandwidth. The reference portion contains substantially only the broad bandwidth. The analyte portion and the reference portion are measured and compared to calculate an amount of the analyte in the sample.Type: GrantFiled: July 20, 2004Date of Patent: April 17, 2007Assignee: Integ, Inc.Inventors: Brian J. Erickson, Philip J. Stout, Joel R. Racchini

Patent number: 7182910Abstract: A body fluid is collected for testing for an analyte contained within the body fluid. The fluid is collected in an apparatus including a reservoir for receiving and collecting a flow of body fluid from a discharge end of a conduit. A capillary test space is in fluid flow communication with the reservoir. The capillary test space is positioned to be in contact with the fluid in the reservoir after the fluid has accumulated to a predetermined transfer volume of fluid. The capillary test space is sized to wick the fluid from the reservoir when the fluid contacts the capillary test space.Type: GrantFiled: June 30, 2003Date of Patent: February 27, 2007Assignee: Integ, Inc.Inventors: John J. Allen, Joel R. Racchini

Patent number: 5800392Abstract: An apparatus for delivering an agent to a treatment area. The apparatus includes a catheter that has a distal portion and a proximal portion. The catheter defines a lumen. A pressure regulator is in fluid communication with the lumen. A selectively inflatable member is also in fluid communication with the lumen, and is formed from a membrane. The membrane has first and second portions. The first portion defines pores sized from about 0.05 .mu. to about 1 .mu. and has a pore density from about 10.sup.6 pores/cm.sup.2 to about 10.sup.9 pores/cm.sup.2. The flux rate is from about 0.001 ml/(min.multidot.cm.sup.2 .multidot.atm) to about 0.4 ml/(min.multidot.cm.sup.2 .multidot.atm). The second portion is substantially impermeable.Type: GrantFiled: May 8, 1996Date of Patent: September 1, 1998Assignee: eMed CorporationInventor: Joel R. Racchini

Patent number: 5498238Abstract: A method of simultaneous angioplasty and drug delivery to a localized portion of coronary or peripheral arteries or any other type of body passage that has a stricture. The invention contemplates positioning a drug delivery device in a body passageway and then selectively introducing a selected drug so that the device is expanded in order to dilate the passage and then simultaneously causing the drug to be transported across a drug transport wall of the device for direct contact with the passageway wall. A more specific aspect of the present invention involves treating a dilated vessel in the area of a stenotic lesion with a fixative or other drug to render the vessel biologically inert and to form a biological stent or prevent restenosis using specifically selected drugs.Type: GrantFiled: August 27, 1993Date of Patent: March 12, 1996Assignee: CorTrak Medical, Inc.Inventors: James E.
