  • Patent number: 12029910
    Abstract: Implementations described and claimed herein provide systems and methods for delivering and retrieving a leadless pacemaker. In one implementation, a leadless pacemaker has a docking end, and the docking end has a docking projection extending from a surface. A docking cap has a body defining a chamber. A retriever has sheaths extending with lumens distally from the chamber. A snare extends between the lumens forming a first snare loop pointing in a first direction and a second snare loop pointing in a second direction with a docking space formed therebetween. The snare is movable between an engaged position and a disengaged position by translating the first snare wire and the second snare wire within the first snare lumen and the second snare lumen. The engaged position includes the first snare wire and the second snare wire tightened around the docking projection within the docking space.

  • Patent number: 12029618
    Abstract: A surgical tool positioning device for positioning and holding a surgical tool is disclosed. The device includes an adjustable-friction ball and socket joint configured to provide three degrees of rotational freedom. A variable holding force may be applied to the ball via a locking member to selectively lock and unlock the adjustable-friction ball and socket joint. The socket includes a friction-inducing member housed therein and in contact with the ball. When the ball and socket joint is unlocked, this friction-inducing member provides sufficient frictional force to hold a position of the surgical tool. However, this frictional force may be overcome with intentional external forces such as during repositioning of the surgical tool.

  • Patent number: 12011559
    Abstract: A single lumen, multiple entry dilator sheath assembly is provided for delivering medical devices in different parts of cardiovascular system. The multiple holes allow multiple guidewires to enter the dilator-delivery sheath system distally and exit from a single lumen proximally thereby providing extra support to the delivery system while tracking over complex paths. Such a multi guide wire system has a definite advantage even over a two-wire system because, although two wire system may offer better support as compared to single wire, it will not be as good as a four wire system. Also, in two wire system the wires are fixed in their position and therefore overcoming the memory of sheath and dilator system will not be as good as with multi-wire system because of the ability to use the multiple entry holes in various permutations and combinations.
