摘要： A device and system for closure of an opening formed in a body vessel includes a bioabsorbable grasping member and locking member. The grasping member includes grasping lingers that are radially collapsible to the closed positions by movement of the locking member over the fingers. A distal portion of the fingers is configured to grasp an outer wall portion of the body vessel surrounding the opening when the fingers are in the open position. Movement of the locking member can cause the fingers to at least substantially close the vessel opening. Structural features on the fingers and/or locking member can inhibit proximal or distal movement of the locking member when in a locking position. A detachable arm can be coupled to the grasping member to facilitate placement of the grasping member. A sheath can fit over the detachable arm and be configured to move the locking member over the fingers.

摘要： Medical devices, as well as methods of treatment and manufacturing such devices, are provided for applying vascular therapy locally within the body vessel. The medical devices include an expandable tubular frame and a sleeve or graft material. The medical devices can be used for local delivery of a therapeutic agent within a body vessel or a tamponade for a lacerated body vessel, while simultaneously allowing perfusion of fluid or blood flow distal of the implanted medical device. The tubular frame of the medical device may have a proximal non-expanding portion and a distal self-expanding support structure. The self-expanding support structure can expand radially outward to urge the graft material to contact the wall of the body vessel. In the expanded configuration, a portion of the device allows fluid flow to continue while the sleeve is against the body vessel wall.

摘要： An occluding device is provided for occluding fluid flow through a lumen of a body vessel. The occluding device includes an expandable tubular body having a tubular wall defining a lumen formed therethrough. The tubular wall has a proximal end extending to a distal end along a longitudinal axis of the tubular body. A plurality of longitudinal slits is formed through the tubular wall to define a plurality of flexible strips bound by a proximal non-slit portion and a distal non-slit portion. A plurality of barbs is disposed on the flexible strips. The tubular body is configured to open radially to engage the barbs with the vessel wall defining an expanded state and to collapse along the longitudinal axis to draw the vessel wall radially inward defining a collapsed state. Occluding material is housed within the lumen of the tubular body and the occluding material is configured to move between a collapsed state and an expanded state with the tubular body.

摘要： Among other things, there are disclosed apparatuses and methods for medically sealing an opening in a vessel or wall. For example, in medical applications, a delivery tube is provided for insertion through a sheath into a vessel (e.g. a blood vessel). A dome-shaped seal fixed to a filament, an absorbent and/or compressible buffer, and a locking member are provided in the delivery tube. The delivery tube is configured so that it can be inserted into the vessel through a sheath. Tension is maintained on the filament to hold the seal against the tube or sheath. The sheath is pulled out, which pulls out the tube at the same time, leaving the seal over the opening in the vessel wall. The locking member compresses the buffer against the outside of the vessel and with the filament holds the seal in place against the inside of a vessel.

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 support frame having struts and a weakened frame portion, and a remodelable material tensionably attached to the support frame. The weakened frame portion has a first configuration in which the support frame has a first outward radial force and a second configuration in which the support frame has a second, lesser outward radial force. The remodelable material restricts expansion of the frame from a radially compressed configuration to a radially expanded configuration when the weakened frame portion is in the first configuration. The remodelable material can form one or more valve leaflets adapted to regulate fluid flow in a body vessel, such as a vein.

摘要： Implantable medical devices, such as intraluminally implantable stents and valves, are provided having certain preferred shapes. Preferably, a portion of the implantable medical device can define a sinus region having a preferred geometry. The sinus region can have one or more preferred geometric configurations described herein, for example to mitigate or prevent thrombosis within a body vessel. The medical device can include a valve means, such as one or more valve leaflets positioned within the sinus region. The implantable medical devices can be delivered from a catheter within a body vessel, and are preferably expandable from a compressed configuration to a radially expanded configuration. The implantable frames can be self-expanding or balloon expandable. Portions of the medical device, such as the implantable frame or a valve leaflet, are optionally coated with one or more bioactive materials.
