  • Publication number: 20240245499
    Abstract: An assembly includes a medical device having a stent and a prosthetic valve connected to the stent. The prosthetic valve includes valve leaflets. The assembly further includes a buffer piece having a leaflet cover and a removable attaching structure. The leaflet cover protects the valve leaflets and the removable attaching structure removably attaches the buffer piece to the medical device. The buffer piece prevents contact, imprinting, abrasion, and/or damage to the valve leaflets.

  • Publication number: 20240139007
    Abstract: A stent delivery system comprising a balloon catheter having a catheter shaft with a balloon mounted on a distal end with a self-expanding stent positioned on the catheter shaft proximal to the balloon (tandemly) with a delivery sheath covering the self-expanding stent. In use, the stent delivery system is advanced on the guidewire to the target lesion and the balloon is inflated to dilate the lesion. The balloon is deflated and advanced distally past the lesion until the self-expanding stent positioned proximate the lesion. The sheath is withdrawn, releasing the self-expanding stent to expand and contact the lesion. Once the self-expanding stent has expanded, the stent delivery system and guidewire are withdrawn from the lesion.

  • Publication number: 20230144490
    Abstract: A hypotube having a laser cut wave pattern to improve flexibility. The laser cut wave pattern on the hypotube includes multiple portions that vary the pitch and angle of the cuts. The laser cut wave pattern provides flexibility while maintaining pushability further into the most tortuous vasculature. The laser cut wave pattern also provides the ability to torque the flexible hypotube back and forth, with a 1 to 1 response, without stretching the flexible hypotube. The laser cut hypotube may be used in a number of vascular or neurovascular, such as a guidewire or catheter, or delivery of a stent.

  • Publication number: 20220331552
    Abstract: The present teachings provide a catheter shaft design and configuration for use in the delivering and deploying a medical device, and aspiration removal of occlusion. Specifically, one aspect of the present teachings provides a catheter shaft design having a four-layer construction, an ultra-thin inner layer, a first coil middle layer, and a second braid middle layer, and an outer jacket layer. The first coil middle layer of the catheter shaft is made of a flat wire with width to thickness ratio of at least 2:1. The outer jacket layer of the catheter shaft is made of three different material with a soft durometer forming the distal portion of the outer jacket, a medium durometer material forming the middle/transitional portion of the outer jacket, and a stronger durometer material forming the proximal portion of the outer jacket.

  • Patent number: 10743975
    Abstract: The disclosure relates generally to an extended use systems and devices for management of bladder function for people with urinary dysfunction. The system includes a prosthesis which can include a retaining portion to prevent migration and a valve that can control fluid flow. The catheter can be placed inside the bladder using devices that facilitate insertion and extraction. The placement of the catheter can be done by a trained individual such as a patient, as well as a clinician, a nurse, or a caretaker. Once placed inside the bladder, the catheter can be fully-internal, meaning no portion of the catheter is visible from outside of the patient's body.

  • Patent number: 9443038
    Abstract: Embodiments of the present invention are directed to facilitating tag assignment to data objects as data objects are added to a tag-associated data-object storage system by users of the tag-associated data-object storage system and to facilitate subsequent display, access, and further characterization of data objects that already reside in the a tag-associated data-object storage system. Methods and systems of the present invention provide for automated tag suggestion to users in order to both increase usability of the interface provided to the tag-associated data-object storage systems as well as decrease the likelihood of unnecessary and unproductive tag proliferation within the tag-associated data-object storage system.

  • Publication number: 20080065742
    Abstract: Embodiments of the present invention address deficiencies of the art in respect to the analysis of an information architecture, and provide a method, system and computer program product for contextually categorizing complex data repositories in an information architecture analysis. In an embodiment of the invention, a contextual analysis method for an information architecture can be provided. The method can include identifying a set of roles accessing information within the information architecture, and locating artifacts within the information architecture and determining information systems providing access to the located artifacts. The method further can include linking the roles in the set with the determined information systems, and producing a top-down, multi-faceted contextual view of the information architecture with the roles, artifacts and information systems.

  • Publication number: 20070016244
    Abstract: A ureteral decompression device comprises a guide member and an anchoring structure. The guide member may be introduced through the urethra and bladder into the ureter so that the anchor structure passes a lodged kidney stone. Once past the stone, the anchor structure can be compacted to anchor the guide member in place. The anchor structure will permit leakage and the guide member will provide a leakage path directly past the stone, thus decompressing the kidney.
