    摘要： Medical devices for implantation in a body vessel, and methods of using and making the same, are provided. A medical device includes a frame and a cross-linkable material having at least one cross-linked region and a non cross-linked region, where the cross-linked region maintains the cross-linkable material in connection to the frame. A method of making an implantable medical device includes providing a frame and covering the frame with a cross-linkable material. The method also includes cross-linking at least one region of the cross-linkable material by joining a first region of the cross-linkable material to a second region of the cross-linkable material to form a point of attachment. A method of treating a subject includes the step of implanting the medical device at a point of treatment.

    摘要： A removable filter for capturing thrombi in a body vessel. The filter has anti-thrombogenic, echogenic, and radiopaque features. The features of the filter provide for enhanced identifying and reduced endotheliosis in a body vessel of a patient. Generally, the anti-thrombogenic feature is preferably a fibrinolytic coating disposed on the filter to decrease the accumulation of fibrin thereon. The echogenic feature preferably is comprised of marks formed on the filter that give rise to reflections of ultrasound waves during ultrasonography. The radiopaque feature is preferably a polymeric coating, ceramic coating, or noble metal coating applied on the filter for enhanced fluoroscopy.

    摘要： An iris-type valve assembly for controlling a flow of fluid. The assembly comprises a base member, a rotatable member, and an elongated elastomeric valve sheath. The distal end of the valve sheath is secured to the base member and the proximal end of the valve sheath is secured to the rotatable member. At least one of the valve sheath ends includes a flange that is secured to a valve-receiving surface of the base member or the rotatable member. The base member and the rotatable member are aligned to define an elongated passageway therethrough for passage of an interventional device, and the elastomeric valve sheath is disposed along the passageway and has a longitudinal opening therethrough for passage of the interventional device. Upon rotation of the rotatable member relative to the base member the longitudinal opening of the valve sheath is selectively constrictable to comprise a seal around the interventional device. The assembly may be provided with ratcheting members to inhibit recoil of the rotatable member, and rib members along the inner surface of the valve sheath to enhance the seal provided by the assembly.

    摘要： A medical grasping device (10) for vascular use, having an outer sheath (12), an elongate control member (50) extending within an outer sheath (12) to a distal tip section (54), and a proximal control assembly (22) including an actuation section (24) joined to the elongate control member (50). Adjacent to the distal tip section (54) is a grasping portion (70,70′) that is extendable from the outer sheath (12) to create loops (74,74′) for grasping a target object (T) for repositioning within the vascular system, or for removal from the patient, with loops being retractable into the outer sheath to hold the target object against the device (10) during movement of the device. Elongate control member (50) is preferably a cannula or tube having a lumen (58) extending completely therethrough for placement over a guide wire (28) already in the patient.
