摘要： A system suitable for delivering a therapeutic agent to a target site may include a container for holding a therapeutic agent, a pressure source having pressurized fluid, where the pressure source is in selective fluid communication with at least a portion of the container, a catheter in selective fluid communication with the container and configured for delivery of the therapeutic agent to a target site, a first valve connected between the container and the catheter, a second valve connected between the pressure source and the container, a button configured to selectively actuate the second valve, and a brake assembly coupled to the first valve and configured to selectively permit actuation of the second valve, such that when the first valve is in a first state, the brake assembly blocks the button such that the button does not actuate the second valve.

摘要： A method may include deploying a stent such that at least one opening of the stent is aligned with a tissue surface within a body of a patient, manipulating a tissue portion through the at least one opening of the stent, and securing the tissue portion with respect to the opening of the stent to prevent migration of the stent. Another general aspect of the present disclosure includes a stent. The stent may have a body including a plurality of struts, a covering extending to an end of the body, the end being a proximal end of a distal end, and an anchor secured to the end of the body, where the anchor includes an opening that is exposed with respect to the covering.

摘要： In one or more embodiments, the present invention is directed to a implantable polymer mesh for use in hernia and other soft tissue repair made using amino acid based poly(ester urea) (PEU) polymers. In some embodiments, the implantable polymer mesh is made using linear or branched L -valine based PEUs and displays mechanical properties similar to poly(propylene) (PP), but with significantly less fibrous capsule formation. In some embodiments, the implantable polymer mesh is made using L -valine-co- L -phenylalanine PEUs. In some embodiments, the implantable polymer mesh is made using these PEUs in a composite with an extracellular matrix (ECM). In various embodiments, these amino acid-based PEU materials can be formed into implantable polymer mesh having a conventional size and shape by a wide variety of techniques including conventional compression molding, vacuum molding, blade coating, flow coating, and/or solvent casting.

摘要： The present embodiments provide an endoluminal prosthesis having a stent- graft portion with a superior end and an inferior end and a graft portion. The graft portion is attached to the stent-graft portion at a junction, and the graft portion extends inferiorly from the junction in a pre-delivery configuration. In a first delivered configuration, the stent-graft portion is radially expanded, and in a second delivered configuration, the graft portion is everted and moved superiorly relative to the pre-delivery configuration. A valve may be attached to the graft portion when the graft portion is in the pre-delivery configuration. When delivered, the stent-graft portion is deployed first, and the graft portion and attached valve are then moved superiorly, with at least a portion of the graft portion extending superiorly beyond the superior end of the stent-graft portion.

摘要： A device for use with a uterine tamponade balloon catheter apparatus, such as the Bakri postpartum hemorrhage balloon, is disclosed. The device comprises a stylet comprising a hub at its proximal end. The device is configured to be removably coupled to the tamponade balloon catheter apparatus to aid in the insertion and positioning of the tamponade balloon catheter within the uterine cavity, allowing the balloon to function as intended for the control and management of postpartum hemorrhage and uterine bleeding. Methods of use of the device are also disclosed.

摘要： A tri-point tissue-collection needle configured similarly to a fine-needle-aspiration needle configured to excise intact tissue cores for collection. The distal tip is configured with three beveled points separated by cutting edges, where a single longer/ more distal point is trailed by and circumferentially separated from a symmetrical pair of points, providing a bilaterally symmetrical needle cannula distal end. A stylet may be provided through a lumen of the needle during introduction into a patient body, where the distal end surface of the stylet may be configured to complement the tri-point needle end configuration,
