  • Patent number: 11027124
    Abstract: A tool operable with a catheter in an interventional medical system retrieves a medical device from an implant site, wherein the device includes an attachment feature that forms an annular recess to be engaged by a lasso of the tool for snaring the device, and a distal-most sidewall of the catheter defines a receptacle into which the snared device is retrieved. A guide of the tool includes a sidewall defining a lumen in which the lasso extends for deployment out from a distal opening thereof, to snare and retrieve the implanted device. The sidewall establishes a radial offset between the guide lumen distal opening and the distal-most sidewall of the catheter, when the guide lumen distal opening and a distal opening of the receptacle are located in close proximity to one another, which radial offset is greater than a length of the annular recess formed by the device attachment feature.

  • Patent number: 10905430
    Abstract: A braid for treating an aneurysm can include a first radially expandable segment operable to move from a collapsed state within a microcatheter to a deployed state distal of the microcatheter. The first radially expandable segment can be capable of radially expanding to form an outer occlusive sack in the aneurysm in the deployed state. The braid can also include a second radially expandable segment operable to move from the collapsed state within the microcatheter to the deployed state distal of the microcatheter, wherein the second radially expandable segment is capable of radially expanding inside the outer occlusive sack to form an inner occlusive sack in the outer occlusive sack in the deployed state. An expansion mechanism can be included and be disposed at a proximal end of the first and second radially expandable segments.

  • Patent number: 10905854
    Abstract: A surgical articulation assembly is disclosed, including a control assembly and an articulable portion. The articulable portion includes at least two segments capable of independent movement. The control assembly defines an axis and three user controls configured to be engaged by an operator. Disposed within the control assembly are three pairs of diametrically opposed driving members that effects translation of a connecting member upon engagement of the user controls. An end of the connecting member is attached to one of the first and second segments of the articulable portion. As the connecting member translates with the driving members, the three user controls allow an operator to exert forces at points along the articulable portion. Also disclosed is a method of effecting articulation of a surgical articulation assembly.
