Publication number: 20140275801Abstract: A surgical access system including an access port device. The port device has a port member, a plurality of blades, and an articulation mechanism. The blades are circumferentially arranged about a longitudinal axis of the port member to collectively define an access region. The articulation mechanism defines a pivot point along a length of each blade, and is operable to articulate the blades between collapsed and expanded states. The blade tips collectively define a diameter in the collapsed state that is less than that in the expanded state. The blades rotate about the corresponding pivot point, and the pivot points move longitudinally relative to the port member, in transitioning between the contracted and expanded states. Light source(s) can be integrated with the blades or separately provided to enhance surgical field visibility.Type: ApplicationFiled: March 15, 2013Publication date: September 18, 2014Inventors: Hector J.

Publication number: 20140046194Abstract: Coupler assemblies and methods are disclosed as the coupler assemblies may be used with a catheter. An exemplary coupler assembly includes a spherical linkage coupler for a catheter. The coupler comprises a first cylinder portion for connecting to a structure, and a second cylinder portion for connecting to a distal end of a body of the catheter. The coupler also comprises a spherical linkage including at least two link arms. Each of the two link arms are connected on one end to the first cylinder portion and on the other end to the second cylinder portion. The two link arms connect a portion of the structure to the distal end of the catheter and enable the structure to move relative to the distal end of the catheter in response to an external force exerted on the structure.Type: ApplicationFiled: August 7, 2013Publication date: February 13, 2014Applicant: St. Jude Medical, Atrial Fibrillation Division, Inc.Inventors: Arthur G.

Patent number: 7540043Abstract: This patent document discusses assemblies and methods for transferring a subject from a first surface to a second surface. In varying examples, an assembly includes a first roller and a second roller. An assembly frame rotatably supports the rollers and, in some examples, longitudinally extends from a frame first end to a frame second end. A belt is coupled to the first and second rollers in such a matter that the assembly frame is positioned, at least in part, between the rollers and surrounded by the belt. A motor, powered by a power source, is coupled to the belt via the first or second roller. In one such example, the motor is coupled with a portion of a first roller inner surface. In another example, an outer surface of one or both of the rollers include belt driving projections matable with projection receiving portions disposed on a belt underside surface.Type: GrantFiled: December 2, 2005Date of Patent: June 2, 2009Assignee: Regents of the University of MinnesotaInventors: Mark A.

Patent number: 7300405Abstract: Techniques are described for analyzing auscultatory sounds to aid a medical professional in diagnosing physiological conditions of a patient. A data analysis system, for example, applies singular value decomposition to auscultatory sounds associated known physiological conditions to define a set of one or more disease regions within a multidimensional space. A diagnostic device, such as an electronic stethoscope or personal digital assistant, applies configuration data from the data analysis system to generate a set of one or more vectors within the multidimensional space representative of auscultatory sounds associated with a patient. The diagnostic device outputs a diagnostic message associated with a physiological condition of the patient based on the orientation of the vectors relative to the disease regions within the multidimensional space.Type: GrantFiled: February 18, 2004Date of Patent: November 27, 2007Assignees: 3M Innovative Properties Company, Regents of the University of MinnesotaInventors: Marie A.
