  • Patent number: 11103274
    Abstract: Embodiments of the invention provide a laparoscopic morcellating device and method for removing tissue from a body cavity. The morcellating device includes a containment mechanism having an aperture, a cutting mechanism designed to fit into an interior space of the containment mechanism and a retractor mechanism that is coupled to the cutting mechanism. The containment mechanism and cutting mechanism combination surrounds the tissue and the aperture of the containment mechanism is closed around the tissue. The morcellating device further includes a motor for actuating the retractor such that the cutting mechanism constricts and morcellates the tissue. The laparoscopic morcellating device further allows for torque balancing of the retractor mechanism, gas flow regulation of the body cavity, and safety feedback mechanisms that can alert the surgeon.

    Abstract: A vacuum aspiration control system for use with a vacuum source and an aspiration catheter includes a connecting tube configured to connect the vacuum source with a lumen of an aspiration catheter. An on-off valve is operatively coupled to the connecting tube, and a sensing unit is configured to detect flow within the connecting tube and provide a signal representative of flow. A controller receives the signal to decide whether to open or close the valve. The controller may automatically close the valve to stop flow when flow through the connecting tube is unrestricted, or according to a predetermined timing sequence. The controller can further periodically open a closed valve to determine whether flow has entered an acceptable range. The controller can still further engage pulsed aspiration with a pressure manipulation assembly when flow is restricted or occluded.

    Abstract: A dilatation device 10 includes a support 14 and at least one inflatable tube 16. The inflatable tube is wound helically around the support and also defines a series of inflatable zones 26 along its length, with successive inflatable zones spaced by an intermediate zone 28 that is more resistive to radial expansion than the inflatable zones. The inflatable tube further defines a fluid inlet 22, 24 for: introducing fluid to inflate the inflatable zones; and extracting fluid from the inflatable tube to deflate it, with each inflatable zone being in fluid communication with its successive inflatable zones via the intermediate zones. The axial critical buckling load of the inflatable zones is less than the radial critical buckling load of the inflatable zones, to cause the inflatable zones to concertina axially when the inflatable tube is depressurized, thereby causing the intermediate zones to displace towards each other.

    Abstract: An excisional device may comprise an introducer comprising a distal trough portion and a cutting assembly. The cutting assembly may comprise an axial hand element configured to selectively bow out of and away from the distal trough portion and to retract into the distal trough portion and a helical cutting element wound around the axial band element. A rotating drum may be provided to cause the cutting assembly to selectively rotate, bow and retract according to a mechanically-driven first cutting profile that is defined by a shape of a channel formed in the drum. An optical guidance projector assembly may be coupled to the excisional device and may be configured to visually indicate when a distal portion of the excisional device is aligned with an imaging plane of an imaging probe and in a desired position.

  • Patent number: 10835257
    Abstract: Systems, methods, and devices for the treatment of acute ischemic stroke that provide immediate blood flow restoration to a vessel occluded by a clot and, after reestablishing blood flow, address the clot itself Immediate blood flow restoration advantageously can facilitate natural lysis of the clot and also can reduce or obviate the concern for distal embolization due to fragmentation of the clot. Several embodiments of the invention provide for progressive, or modular, treatment based upon the nature of the clot. For example, the progressive treatment can include immediate restoration of blood flow, in-situ clot management, and/or clot removal depending on the particular circumstances of the treatment. The in-situ clot management can include, for example, lysis, maceration, and/or removal.

  • Patent number: 10806434
    Abstract: An excisional device for either handheld or stereotactic table use may comprise an outer sheath that may comprise a distal trough shape configured to penetrate and/or cut tissue independently or in concert with work element(s). The articulable work element(s) may comprise articulable beak(s) and may be configured to translate and/or rotate at a first rate and to cut tissue in a direction implied by placement of the trough shaped outer sheath. A first helical element or equivalent assembly may be configured to transport tissue cut by the work element(s) and/or trough, may be co-axially disposed relative to the work element(s) and may be operative to rotate at a second rotation rate that is different than the first rate. A proximal sheath may be co-axially disposed relative to the work element(s) and the first helical element, and may be configured to rotate and actuate the work element(s).

  • Patent number: 10806931
    Abstract: Delivery devices, systems, and methods for delivering implantable leadless pacing devices are disclosed. An example delivery device may include a tubular member and a distal holding section extending distally of a distal end of the tubular member and defining a cavity therein for receiving an implantable leadless pacing device. The delivery device may facilitate vascular delivery of the pacing device to a left side of a patient's heart. In one example, a distal tip portion may extend distal of the distal holding section and may be actuated between a closed and an opened position. When in the closed position, the distal tip portion may have a tip that can puncture or engage an opening in a septum between a left atrium and a right atrium of a patient's heart. Actuating the distal tip portion to an opened position may be utilized to dilate the puncture or opening in the septum.

  • Patent number: 10786278
    Abstract: A medical device for grinding substance inside a body lumen includes a rotatable tubular drive shaft, a treatment member connected to the drive shaft, and a tubular member possessing an axially extending lumen that extends throughout the tubular member. The tubular member is mounted on the treatment member and surrounds a portion of the treatment member so that the treatment member is rotatable relative to the tubular member. The treatment member includes a shearing portion, and the tubular member includes a protrusion that projects toward the lumen of the tubular member. The protrusion is located axially in front of the shearing portion and interacts with the shearing portion during relative rotation between the treatment member and the tubular member to shear debris resulting from the grinding of the substance.
