    Abstract: In various embodiments, a drainage device includes an inner lumen configured for draining fluid from a target site and one or more outer lumens for transmitting dilution fluid to the inner lumen. According to one embodiment, the drainage device includes one or more eyelets and/or a distal opening through which the fluid from the target site enters the inner lumen. In one or more embodiments, the dilution fluid is transmitted to the inner lumen through one or more ports that may output the dilution fluid directly into the inner lumen or into the eyelet. According to one embodiment, as the fluid from the target site flows through the drainage device, the dilution fluid reduces clotting processes such that formation of blockages within the inner lumen is prevented or at least reduced. In some embodiments, the dilution fluid is substituted with, or provided in addition to, pharmaceutical solutions or other infusions.

  • Patent number: 10905403
    Abstract: A biopsy device includes a cutter defining a cutter lumen and a tissue sample holder for collecting tissue samples. In one example, the tissue sample holder includes a rotatable manifold, and has a plurality of chambers that are each configured to separately hold tissue samples. A tissue sample holder rotation mechanism is operable to rotate the manifold to successively align each of the chambers with the cutter lumen. A controller in communication with the rotation mechanism is configured to rotate the manifold to a presentation position to present a collected tissue sample within a chamber to a user (e.g., at an angular position approximately 90 degrees from the cutter lumen). The controller is further configured to rotate the manifold align the next, empty chamber with the cutter lumen in response to a user input instructing the biopsy device to obtain another tissue sample.

    Abstract: A medical device is disclosed for cutting an object in a living body lumen. The medical device includes a rotatable elongate member, rotating member having a cutting portion cutting the object and disposed on the distal end side of the elongate member for rotating together with rotation of the elongate member; and a distal member having a guide portion disposed on the distal end side of the rotating member with a space left from the rotating member and a supporting portion which supports the guide portion and defines a dimension of the space in an axial direction of the elongate member. The guide portion is disposed at a position at which the guide portion overlaps with part of the cutting portion and exposes part of the cutting portion as viewed from the distal end side of the distal member.

  • Patent number: 10874552
    Abstract: Ocular lens cutting devices and methods for cutting and removing tissue such as lens fragments from an eye of a patient are disclosed. In one embodiment, an ocular lens cutting device includes an outer member and an inner member positioned within the outer member. The outer member and the inner member can each include at least one cutting edge. The at least one cutting edge of the outer member and the at least one cutting edge of the inner member can cooperate to form a cutting structure as the inner member moves with respect to the outer member. The ocular lens cutting device can also be connected to a vacuum source which can allow the ocular lens cutting device to grasp the tissue to be cut and remove the cut fragments from the surgical area.

  • Patent number: 10869684
    Abstract: A tissue resecting device includes an end effector assembly including a proximal hub housing and a cutting member extending distally from the proximal hub housing, and a handpiece assembly. The handpiece assembly includes a handle housing, a drive casing extending distally from the handle housing, a drive rotor extending through and distally from the drive casing, and a seal ring disposed about the drive rotor. In an at-rest position, the seal ring is sealingly engaged between the drive casing and the drive rotor to inhibit fluid ingress into the annular space. Upon engagement of the end effector assembly with the handpiece assembly, a portion of the proximal hub housing is configured to urge the seal ring from the at-rest position to a displaced position wherein the seal ring is displaced from the drive rotor to reduce friction therebetween upon rotation of the drive rotor relative to the drive casing.

  • Patent number: 10864009
    Abstract: A cardiac valve cutter of the present disclosure has a flexible housing with a central lumen for receiving a guide wire. A high-speed cutting blade is disposed within the housing near an edge of the housing. A trough cut into a side of the housing exposes a portion of the cutting blade so that the cutting blade can cut valve tissue. Two pusher wires are disposed on an opposite side of the housing from the cutting blade. Troughs cut into the side of the housing form openings from which the pusher wires can extend. The pusher wires are staggered with respect to one another in the longitudinal direction. When the pusher wires are advanced, they extend outwardly from the troughs and can be used to stabilize the cutter at the cardiac valve and push the cutting blade against the valve on the opposite side.

  • Patent number: 10864012
    Abstract: A tool bit for an ultrasonic osteotome includes a bit body, an arbor fixed to the bit body, and a flat end portion fixed to the arbor. A toothed edge extends linearly along a length direction of an end portion of the tool bit, and recesses are distributed evenly on the toothed edge to form teeth spaced apart from each other. The toothed edge extends linearly along a length direction, and the cutting edges of teeth are distributed linearly, e.g., instead of having a sharp structure, thus will not scrape and hurt other tissues during cutting. Since the thickness of the cutting edge is the same as that of the back edge, when cutting bone tissues, the incision is wide, thus the end portion is not easy to be clamped by bone tissue, which effectively prevents the end portion from breaking and reduces occurrence chances of surgery accidents.

  • Patent number: 10856899
    Abstract: A balloon catheter (1) including a device (3) adjacent the distal end (12) of a catheter (10) for guiding a boring tool (5) or other instrument into an occlusion (6) in a vessel (8), includes a guide element (30) adjacent the distal end (12). A penetrating element (33) having a first guide bore (38) terminating in a distal cutting edge (40) is rotatable in a second guide bore (45) extending through the guide element. External threads on the penetrating element (33) are engageable with internal threads in the second guide bore (45), so that by rotating the penetrating element (33) the distal cutting edge (40) is urged outwardly to penetrate the occlusion (6). With the penetrating element (33) securely engaged in the occlusion (6), a boring tool (5) and other instruments can then be sequentially guided through the catheter (10) and the first guide bore (38) directly into the occlusion.
