  • Patent number: 9375234
    Abstract: A medical device, such as a guidewire, catheter, or the like, that includes an elongated tubular member that includes a plurality of angled slots defined in at least a distal section thereof. The plurality of angled slots can form a generally spiral shaped pattern about the longitudinal axis of the tubular member, and can be useful, for example, in aiding a user of the device in crossing an occlusion in a vessel of a patient. In some embodiments, the distal section of the tubular member may have an outer diameter that is greater than the outer diameter of a proximal section of the tubular member. In some embodiments, a proximal section of the tubular member may include a plurality of slots defined therein, for example, that may be configured to increase the lateral flexibility of the tubular member.

  • Patent number: 9375216
    Abstract: An apparatus for performing a vascular treatment includes an intraluminal member that is controllingly moved during the vascular treatment. The intraluminal member of the vascular treatment device can be connected to a motor. The rotation direction of the intraluminal member can be reversed to reduce the incidence and duration of vein entanglement during a vascular ablation procedure. Reversal of direction could occur automatically, or in response to a sensor such as a load sensor provided as part of the motorized drive system.

  • Patent number: 9320510
    Abstract: Bone anchors useful in rotator cuff repair optimize the thread pattern for engaging different types of bone tissues, including harder cortical bone and softer cancellous bone. Bone anchors may include fine threads for engaging cortical bone and coarse threads for engaging cancellous bone. Threads can be made finer by increasing root diameter and surface angle of the threads. The pitches of the fine and coarse threads are kept the same, which allows fine threads to follow the impression created by coarse threads as the anchor is driven into a bone. Threads that engage cortical bone can be multi-fluted and include a first flute that follows the same thread pattern as coarse threads such that first flute follows the groove created by the coarse threads as the bone anchor is driven into a bone. Bone anchors can have a distal non-threaded stabilizing extension at the distal end.

  • Patent number: 9289226
    Abstract: A method for detaching an object from a patient includes providing a tool having a sheath, and a separating assembly operably coupled to a distal end of the sheath. The separating assembly includes a separator moveably coupled to a tip via a threadable connection. The separating assembly is placed near patient tissue that is attached to the object, the sheath is rotated to move the separator distal to the tip, and the separator is applied to the patient tissue that is attached to the object, so as to separate the tissue. A separating system includes a sheath, and a separator threadably coupled with a distal end of the sheath. The separator is adapted to switch between a first configuration where a separating mechanism is deployed, and a second configuration where the separating mechanism is undeployed.

  • Patent number: 9247961
    Abstract: The foreign object extractor has an elongated hollow tube with a central lumen through its entire length providing fluid connection between an engaging end and a vacuum source. The engaging end has a nominally round transverse cross-section and is shaped to engage a foreign object to be removed from the human body. The engaging end flares so as to expose the internal surface of the elongated hollow tube for engagement with the foreign object. An adhesive is disposed on the exposed internal flared surface of the distal end. Pneumatic suction is applied through the lumen of the extractor and the suction serves to bring the foreign object into contact with the adhesive coated surface of the extractor to form a bond between the extractor and the object to be extracted.

  • Patent number: 9198664
    Abstract: Described here are devices for closing one or more tissues, and handles for controlling these devices. Generally, the devices described here comprise a snare loop assembly, wherein the snare loop assembly comprises a snare and a suture loop, and a handle for controlling the snare loop assembly. In some variations the snare loop assembly may comprise a retention member that may releasably connect the suture loop to the snare. In other variations the devices comprise one or more force-reducing suture locks to help prevent the suture loop from inadvertently disengaging from the snare loop assembly. In still other variations, the excess-suture management features. The handles described here may be configured to remove excess suture from a suture loop, and may also be configured to release the suture loop from the snare loop assembly.
