  • Patent number: 10463495
    Abstract: Delivery devices for delivering encircling implants can include two separate limbs that are held together at a distal articulation by the implant being delivered. The implant can comprise a suture and/or a braided tube. The implant can extend through or over the limbs. The implant and at least a distal portion of the limbs can be compressible into a delivery shape that allows for advancement through the lumen of a delivery catheter. When the distal portion of the limbs move out of the delivery catheter, the limbs and implant can resiliently assume a loop shape that is complementary to a shape of a target around which the encircling implant is to be placed. The limbs are then retracted from along the implant to leave the implant in the desired delivery position. The delivery device can be used to place encircling implants around the heart or other targets, and the implant can be tightened to exert compressive force on the target.

  • Patent number: 10335185
    Abstract: Disclosed is a snare instrument with a shaft area, a snare structure in a snaring area distally adjoining the shaft area, and a plurality of noose wires. The snare structure can be pulled closed, from an opened position with distally open snare, and has a plurality of flexible bending tubes which extend distally forwards and radially outwards in a radiating shape to form the snare, and of which the distal ends can be moved radially inwards towards each other so as to pull the snare structure closed. Each noose wire extends with a first base portion from the shaft area loosely through one of the bending tubes as far as the distal end thereof, from there with a noose arch to the distal end of the same or another bending tube, and from there with a second base portion loosely through the latter back to the shaft area. At least one of the noose wire base portions extends through each bending tube.

  • Patent number: 10265118
    Abstract: A surgical instrument comprises a handle assembly including an actuator mounted for manipulation through an actuation stroke. An elongate shaft extends distally from the handle assembly and defines a longitudinal axis. A reciprocating member extends at least partially through the elongate shaft, and is mounted for longitudinal motion through the elongate shaft in response to manipulation of the actuator through the actuation stroke. A drive mechanism includes a first rotating component coupled to the actuator about a first circumference to induce rotational motion in the first rotating component. A second rotating component is coupled to the first rotating component such that rotational motion in the first rotating component induces rotational motion in the second rotating component. The second rotating component is coupled to the reciprocating member about a second circumference such that rotational motion of the second rotating component induces longitudinal motion in the reciprocating member.

  • Patent number: 10231746
    Abstract: A medical retrieval basket used for entrapping and extracting objects such as urinary and biliary calculi from the body comprising a handle assembly, a flexible shaft, and a basket. The basket comprises a plurality of outwardly disposed shape memory wires and is bulbous in shape at its distal end. Located at the intersection point of the wires at the distal end of the basket is a hub that restricts the degree of relative movement between the wires. This hub also serves to increase contact points with the object to be retrieved and to stabilize the orientation of the basket wires. The substantially tipless configuration of the distal end of the basket permits the basket to retrieve objects from difficult to reach locations and reduces tissue trauma caused by the basket tip. The basket wires have varying cross sectional shapes and sizes in different sections of the basket to optimize the performance to the needs of each section within the basket.
