  • Patent number: 11166738
    Abstract: Disclosed is a wrapping cape system which displays favorable grasping characteristics in operations for the entrapment and removal of blocking items in tubular geometries. The wrapping cape system yields a configuration that surrounds the blocking item, such as a thrombus, peripherally, thus capturing its body tangentially and allowing the operator to pull it along the surrounding tube (for instance vein or artery) by utilizing shear forces distributed along the surface of the blocking item in its axial direction. The advantage stems from the fact that the blocking item is not pushed from behind during its withdrawal, but pulled instead; also, since there is no penetration, fragmentation is avoided.

  • Patent number: 11007046
    Abstract: A urinary stent includes ends for deployment in the kidney and bladder, respectively, that are non-coplanar. The bladder end of the stent includes a luminary groove, covered by a sleeve of materials softer than the remainder of the stent, allowing urine at sufficient pressures to pass out from the stent, between the stent and the sleeve. The bladder end of the stent adapts its shape according to respiratory changes in the length of the stent. This shape change also prevents or reduces stent related pain.

  • Patent number: 10960142
    Abstract: A detent mechanism for controlling translation between two components in a longitudinal direction includes a resilient beam on one of the components and a rhomboid ramp member on the other component. The resilient beam is essentially straight when relaxed and has a first beam head and is arranged to interact in a ramped engagement with respectively one of two ramps. Each ramp is on one longitudinal side of the rhomboid ramp member such that application of a translative force between the components in one longitudinal direction with the first beam head engaged to one of the ramps in a first state deflects the resilient beam in one transversal direction and such that application of a translative force between the components in the other longitudinal direction with the first beam head engaged to the other one of the ramps deflects the resilient beam in the other transversal direction.
