  • Patent number: 12268392
    Abstract: Implantable medical devices for connecting tissue layers, such as for connecting a gallbladder and a portion of a gastrointestinal tract to create an anastomosis, include a tubular structure having a plurality of apposition portions, a central region, and a covering material. The devices are endoscopically deployable and may include open cells or undulating edges that facilitate a secure connection between the tissue structures.

  • Publication number: 20240252756
    Abstract: The present disclosure relates to medical delivery devices that include a barrel having an inner surface, and in at least one embodiment, the inner surface is hydrophilic. The medical delivery device may further include a stopper may having an elastomeric body, one or more fluoropolymer layers, and two or more ribs laminated to the one or more fluoropolymer layers. In some embodiments, the contact angle of the inner surface of the barrel is less than about 58°. Additionally, the stopper includes a sliding surface that is less than about 2.0 mm. The barrel provides inner surface that in combination with the fluoropolymer laminate or fluoropolymer film achieve high levels of air and liquid impermeability while also maintaining an acceptably low break loose force, low average glide force, and low glide force variation. In some embodiments, the compressibility stopper against the barrel is greater than about 7.9%.

  • Patent number: 8864675
    Abstract: An improved catheter is provided. The catheter may include a deflectable member located at a distal end of a catheter body. The deflectable member may comprise an ultrasound transducer array. The deflectable member may be interconnected to the catheter body by a live hinge. The catheter may include a lumen extending from a proximal end of the catheter body to the distal end. The lumen may be used to deliver an interventional device to a point distal to the distal end of the catheter body. The deflectable member may be selectively deflectable in a pivot-like manner through an arc of at least 90 degrees. In embodiments where the deflectable member includes an ultrasound transducer array, the ultrasound transducer array may be operable to image both when aligned with the catheter body and when pivoted relative to the catheter body.
