Patent number: 7890192Abstract: A method for inserting a lead electrode into body tissue using a rotatable lead introducer is described. The introducer can include a distal element for releasably engaging a lead head controllable from a proximal control located outside of the body. An inner stem can extend between a proximal portion and a distal portion, and be pivotally and rotatably coupled to the distal lead engagement mechanism. An outer tube can be rotatably disposed over the inner stem and be flexibly coupled over the pivot to rotationally drive the distal element. A helical epicardial-myocardial lead electrode can be secured and oriented straight ahead and introduced through a port or small incision with the introducer in a straight configuration. The introducer can then be bent and rotated to screw the helical electrode into the heart.Type: GrantFiled: June 5, 2009Date of Patent: February 15, 2011Assignee: Greatbatch Ltd.Inventors: Daniel N. Kelsch, James L. Mellor, Kenneth P. Rundle, Roger B. Fell, Scott E. Jahns, Dave S. Erickson, Vincent A. Fischer, III, Kent D. Anderson

Patent number: 7885255Abstract: A synchronous read channel having a single chip integrated circuit digital portion which provides digital gain control, timing recovery, equalization, digital peak detection, sequence detection, RLL(1,7) encoding and decoding, error-tolerant synchronization and channel quality measurement is disclosed. The integrated circuit accommodates both center sampling and side sampling, and has a high degree of programmability of various pulse shaping and recovery parameters and the ability to provide decoded data using sequence detection or digital peak detection. These characteristics, together with the error-tolerant sync mark detection and the ability to recover data when the sync mark is obliterated, allow a wide variety of retry and recovery strategies to maximize the possibility of data recovery.Type: GrantFiled: May 23, 2008Date of Patent: February 8, 2011Assignee: Lake Cherokee Hard Drive Technologies, LLCInventors: Richard T.

Patent number: 7549654Abstract: A wheel-mounted, heavy-duty wire rack system for shipping, storage, and delivery of environmental suits and other garments includes a multi-shelf wire rack mounted on a sturdy wheeled base. The base is a steel frame with four casters and a pair of forklift guides attached to the underside of the frame. The multi-shelf wire rack is attached to the topside of the frame, and includes four upright posts and a plurality of reinforced wire shelves attached to and extending between the posts. Further, a set of wire mesh panels is attached to the posts and shelves to enclose the sides of the wire rack, thereby forming a single front opening for each shelf. Fabric covers are positioned over the multi-shelf wire rack for preventing items from falling out during shipping and handling. Additionally, fabric shelf dividers or bins are positioned on the shelves for storage and organization of smaller items.Type: GrantFiled: May 20, 2003Date of Patent: June 23, 2009Assignee: Unifirst CorporationInventors: Kent D.

Patent number: 7365671Abstract: Method and apparatus for processing transmitted data. A sampling circuit preferably performs lossy sampling of a continuous signal to provide a corresponding sequence of discrete samples at a sampling rate less than a Nyquist rate of the continuous signal. A processing circuit reconstructs an informational content of the continuous signal from the discrete samples, and operates to periodically insert additional samples into the sequence, which preferably increases an effective rate of said sampling to match or exceed the Nyquist rate. Preferably, the lossy discrete samples are temporarily stored in a memory space prior to reconstruction by the processing circuit. The sampling circuit preferably comprises an analog-to-digital converter (ADC) of an analog front end (AFE). The processing circuit preferably comprises a digital back end (DBE) employing partial-response, maximum-likelihood (PRML) detection. The additional samples are preferably provided by an iterative timing recovery (ITR) block of the DBE.Type: GrantFiled: October 10, 2006Date of Patent: April 29, 2008Assignee: Seagate Technology LLCInventor: Kent D.

Patent number: 7323001Abstract: The invention provides a device for filtering emboli from blood flowing through a lumen defined by the walls of a vessel in a patient's body comprising a filter element. The filter is expandable from a collapsed configuration when the filter element is restrained to an expanded configuration when the filter element is unrestrained, and the filter element comprises a self-expanding material having pores. When the filter element is in the expanded configuration, the average pore size is from 30 to 300 microns and the standard deviation of the pore size is less than 20 percent of the average pore size.Type: GrantFiled: January 30, 2003Date of Patent: January 29, 2008Assignee: ev3 Inc.Inventors: Thomas L.

Patent number: 7232452Abstract: A method and system of performing an intravascular procedure at a treatment site in a vessel of a patient. A device creates a seal to prevent the flow of blood during the treatment of vascular disease. A seal may be formed between the distal inside diameter of a sheath or catheter such as a guide catheter as well as within a vessel, such as an artery or vein. An elongated device having a distal portion extending from the catheter and having a fluid impermeable membrane disposed about at least the distal end of the device is used to seal the vessel. The system includes a device to occlude blood flow and a distal protection device to filter or remove embolic debris.Type: GrantFiled: July 12, 2002Date of Patent: June 19, 2007Assignee: ev3 Inc.Inventors: Daniel O. Adams, Richard S. Kusleika, Kent D. Anderson

Patent number: 7196644Abstract: A signal processing system includes a receiver for receiving an analog signal. The system also includes an analog-to-digital converter (ADC) coupled to the receiver. At each of a series of time intervals, the ADC outputs sequential digital codes. Each digital code corresponds to a sampled analog value of the received analog signal at each sample interval. The system further includes a memory in which the sequential digital codes may be stored, and a processing circuit for converting the digital codes into a series of binary data bits. The conversion may be performed in a different sequence than the sequence in which the digital codes are stored in the memory.Type: GrantFiled: July 1, 2004Date of Patent: March 27, 2007Assignee: Seagate Technology LLCInventors: Kent D. Anderson, Gregory L. Silvus, Robert W. Warren, Jr.
