  • Publication number: 20210282845
    Abstract: An electrosurgical medical device may include a conductive tubular element disposed about an outer surface of an elongate tubular member at a distal portion of the tubular member. The conductive tubular member may be delivered to a treatment site of a gastrointestinal (GI) tract of a patient and electrically activated. While electrically activated, the conductive tubular element may create an opening in a wall of the GI tract and a pseudocyst. After the incision is made, the conductive tubular element may be withdrawn from the treatment site and a drainage device may be positioned in the incision for drainage of the pseudocyst.

  • Patent number: 10993742
    Abstract: A single-wire stylet may be constructed as an elongate single-wire, memory-metal alloy body with a generally cylindrical body profile, extending distally from a proximal end terminus, where embodiments include a polymeric distal tip member fixedly attached directly at a distal end of the single-wire body. At least one lengthwise portion of the single-wire body is at least partially in martensitic phase at operating temperatures at and below about 37° C. Where present, the polymeric distal tip member has a generally cylindrical body profile circumferentially bounded by an outer circumference substantially equal to or greater than that of the metal body. The polymeric distal tip member may be overmolded upon a distal-end tip length of an elongate single-wire, memory-metal alloy stylet body, where the distal end and/or discrete intermediate distal-portion length(s) that include martensitic-phase alloy and any polymeric member have greater flexibility than a proximal-most length of the alloy stylet body.

  • Patent number: 10363407
    Abstract: Embodiments include a fiducial deployment system with a handle configured for actuation of the same, the handle including a collet mechanism actuatable for controlled, one-at-a-time deployment of fiducials. A fiducial may include one or more protuberances configured to engage one or more slots in a needle of the system. The needle may be configured to deliver a plurality of fiducials to a target location in serial fashion, one at a time. In certain embodiments, echogenic placement of fiducials may present certain advantages. The handle includes an actuation mechanism with a collet and plunger actuation member configured for incrementally or otherwise controlledly deploy one or more fiducials at a time by advancing a sty let through and/or retracting the body of a slotted needle in which fiducials are disposed with a fiducial protrusion extending into the needle slot, which also includes retaining structures that do not impede the needle lumen.

  • Patent number: 9980699
    Abstract: Disclosed are embodiments of devices and methods for providing enhanced echogenicity to medical devices. At least two adjacent echogenic features with an intervening section positioned between the echogenic features are formed as a helical groove in a medical device surface. Each of the echogenic features has a depression that spans between first and second transition lips. In one form, each depression includes a steep portion adjacent a shallow portion wherein the steep portion has a first radius and the shallow portion has a second radius that is larger than the first radius such that the radii capture different wavelengths of ultrasound. The intervening section has a planar surface in which the first and second transition lips do not extend above. In one form, each of the at least two echogenic features has a length that is within 0.1 mm of a length of the intervening section.

  • Patent number: 9855403
    Abstract: A medical device includes an elongate single-wire memory-metal body with a complete length that includes a proximal stylet length, an intermediate self-coiling stylet length, and a distal stylet length that is generally straight and non-self-coiling. The moment of force of the self-coiling stylet length is less than the moment of force of the medical endoscopy needle that is resistant to the stylet's self-coiling force. The device may further include being incorporated into an endoscopy needle system where the single-wire stylet body is disposed through a lumen of a medical endoscopy needle.

  • Patent number: 9750532
    Abstract: Access needles and methods of using the needles are set forth in this disclosure. The needles can include a handle and a cannula having a proximal end operatively connected to the handle, a distal end, and a lumen extending through the body of the cannula. A protective sheath may surround the cannula. Further, a stylet may be removably disposed within the lumen of the cannula. The stylet includes a piercing tip at a distal end and a flexible body length extending proximally from the piercing tip to the handle. The flexible body of the stylet provides a path of fluid communication through the lumen of the cannula such that a contrast fluid can effectively pass through the lumen of the cannula. Methods of introducing cannulas to target locations within a body of a patient are also set forth in this disclosure.

  • Patent number: 9615949
    Abstract: A delivery device for deploying an expandable prosthesis and method of use thereof are described. The delivery device includes an outer sheath that is capable of retracting in a proximal direction and resheathing over the prosthesis in a distal direction. The device includes a drive pulley that can engage gears to retract or resheath the outer catheter in relation to the prosthesis. In some embodiments, the delivery device may include a reinforced outer sheath disposed over an inner elongate member, the reinforced outer sheath comprising a proximal section reinforced with a braid, a distal section reinforced with a coil and an overlapping section extending between the proximal section and the distal section. Additionally or alternatively, the delivery device may include a stabilizing element for releasably holding the stent to the inner catheter.
