Patent number: 9339256Abstract: Changes in tissue stiffness have long been associated with disease. Systems and methods for determining the stiffness of tissues using ultrasonography may include a device for inducing a propagating shear wave in tissue and tracking the speed of propagation, which is directly related to tissue stiffness and density. The speed of a propagating shear wave may be detected by imaging a tissue at a high frame rate and detecting the propagating wave as a perturbance in successive image frames relative to a baseline image of the tissue in an undisturbed state. In some embodiments, sufficiently high frame rates may be achieved by using a ping-based ultrasound imaging technique in which unfocused omni-directional pings are transmitted (in an imaging plane or in a hemisphere) into a region of interest. Receiving echoes of the omnidirectional pings with multiple receive apertures allows for substantially improved lateral resolution.Type: GrantFiled: February 21, 2013Date of Patent: May 17, 2016Assignee: MAUI IMAGING, INC.Inventors: Donald F.

Patent number: 9339282Abstract: A guidewire is provided with first and second helical members at the distal end of the guidewire. The helical members enmesh with each other in a retracted state. The second helical member is extended from the first helical member by rotating a tubular member and core member relative to each other. This causes the first and second helical members to be driven apart from each other along a helical path defined by the engagement between helical members.Type: GrantFiled: March 6, 2013Date of Patent: May 17, 2016Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Sara M.

Patent number: 9339289Abstract: An ultrasonic surgical instrument including an ultrasonically actuated blade or end effector having a treatment portion. The blade can define a central axis and at least one axis which is transverse to the central axis, wherein the transverse axis can lie within a plane which is perpendicular, or normal, to the longitudinal axis and can define a cross-section of the treatment portion. Such a cross-section can include a central portion and a step extending from the central portion, wherein the central portion can comprise a width, and wherein the step can comprise a cutting edge. In at least one embodiment, the cutting edge can be defined by first and second surfaces which define an angle therebetween. In various embodiments, the position of the cutting edge and/or the angle between the cutting edge surfaces can be selected in order to balance the blade with respect to the transverse axis.Type: GrantFiled: June 18, 2015Date of Patent: May 17, 2016Assignee: Ehticon Endo-Surgery, LLCInventor: Galen C. Robertson

Patent number: 9339291Abstract: A cutting or scoring balloon (10) of elongate shape and provided at its periphery with a plurality of scoring elements (12) extending longitudinally along the balloon. The scoring elements (12) are formed integrally with the balloon wall (14) and in the preferred embodiment are of the same material. A raw material form (20) for producing the balloon (10) is provided with a series of zones (26, 28) of greater thickness compared to the remainder of the balloon wall (24). These zones (26, 28) are located adjacent respective ribs (22) and extend longitudinally along the balloon wall for substantially the same distance as the ribs (22). The zones (26, 28) ensure that these will expand (stretch) preferentially compared to the remainder of the raw material form (20) and in particular the ribs (22), with the effect that the ribs (22) will not tend to be stretched.Type: GrantFiled: December 9, 2010Date of Patent: May 17, 2016Assignee: Cook Medical Technologies LLCInventors: Steen Aggerholm, Per Erik Elgaard, Thomas Lysgaard

Patent number: 9339293Abstract: Implementations described and claimed herein provide controlled access into the intra-pericardial space. In one implementation, a medical device comprises an outer sheath, an inner sheath, and a nose shaft. The outer sheath comprises a proximal end, a distal end, and a lumen extending between the proximal end and the distal end. The inner sheath extends through the lumen of the outer sheath and comprises a distal portion adapted to pierce the pericardial sac. The nose shaft is adapted to displace relative to a distal edge of the distal portion of the inner sheath. Displacing the distal portion of the inner sheath relative to the outer sheath until the nose shaft displaces relative to the distal edge provides controlled penetration into the intra-pericardial space.Type: GrantFiled: July 8, 2015Date of Patent: May 17, 2016Assignee: PACESETTER, INC.Inventor: Kevin L.
