Patent number: 11628286Abstract: 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: GrantFiled: November 23, 2015Date of Patent: April 18, 2023Assignee: St. Jude Medical, Atrial Fibrillation Division, Inc.Inventors: Arthur G.

Patent number: 10646275Abstract: Apparatus and methods for ablating material in a region within a vascular system of a patient are provided. A determination of at least one of a type of material in the region and an indication of a distance to the material in the region is made based on at least one property of the region determined from light reflected from the region. Light from a light source is transmitted in at least one of a plurality of optical fibers based on the determination, and at least some of the transmitted light is received at a first emitter disposed along a length of a laser catheter proximate a distal end thereof. The first emitter radially transmits the at least some of the light from the length of the laser catheter so that the light impinges upon and ablates the material through an opening in the length of the laser catheter.Type: GrantFiled: December 30, 2014Date of Patent: May 12, 2020Assignee: REGENTS OF THE UNIVERSITY OF MINNESOTAInventors: Timothy M.

Patent number: 9072501Abstract: 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: GrantFiled: March 15, 2013Date of Patent: July 7, 2015Assignee: Regents of the University of MinnesotaInventors: Hector J.
