    摘要： Medical devices that are formed from a polymeric matrix including a first polymer and a functionalized polymer are provided. The medical devices may include a functionalized polymer such as maleic anhydride functionalized polymer. The burst strength and/or the hoop strength of the medical devices including the functionalized polymer may be greater than the burst strength and/or the hoop strength of control medical devices. However, the durometer of the medical devices may be substantially equal to the durometer of the control medical devices. Methods of manufacturing medical devices including a functionalized polymer are also provided.

    摘要： Catheters and methods for supporting a guidewire or delivering a radiopaque, diagnostic or therapeutic agent through a vessel stenosis or other tortuous anatomy are disclosed. A catheter can comprise an elongate shaft body and a tip member disposed at a distal end of the shaft body. The shaft body can extend from a proximal end to the distal end and can define an inner lumen. The shaft body can include a liner, a braid member surrounding the liner, a multi-layer coil surrounding the braid member, and a polymer cover surrounding the multi-layer coil. An outer surface portion of the polymer cover can include one or more helical threads, which can be enveloped in an outer wrapper. The tip member can be made from a metal or a polymer. Polymer tip members can include a hard or semi-hard distal tip.

    摘要： A radiopaque structure and an implanted medical instrument having the radiopaque structure. The radiopaque structure includes at least one radiopaque unit, and each radiopaque unit includes at least one radiopaque object. In at least one incidence direction of a light source, all the radiopaque objects in the radiopaque structure are divided into n regions according to the thickness in the incidence direction, and a projection area Sm of m regions of the n regions and an effective thickness dm of the m regions meet Sm−0.0136(dm)a≥0, wherein −0.95≤a≤−0.85 and 1≤m≤n. The radiopaque structure has good or excellent visibility.

    摘要： Embodiments herein include delivery systems for active agent coated balloons and related methods. In an embodiment, a delivery system can include a tunneling sheath and a balloon catheter. The tunneling sheath can include a tubular shaft having an outer diameter and defining a lumen. The tunneling sheath can include a proximal collar defining a lumen. The balloon catheter can include a balloon catheter shaft disposed within the tubular shaft. The balloon catheter shaft can include a lumen for the passage of a fluid therein. The balloon catheter can include an expandable balloon disposed on the balloon catheter shaft. The balloon catheter shaft can include an active agent layer disposed on the expandable balloon. The position of the expandable balloon can be configured to be stationary relative to the tubular shaft as the delivery system is passed through a blood vessel of a patient. Other embodiments are also included herein.
