  • Publication number: 20140155973
    Abstract: Devices, systems and methods are provided for anchoring implantable medical devices to maintain an implanted position. In some embodiments, the medical devices are stimulation leads which are implanted near a portion of the neural anatomy for providing stimulation thereto. To maintain position of the lead, the lead is anchored with the use of a tissue-captured anchor which is attached to the lead at a desired point of anchoring. The anchor maintains position of the lead by resisting movement of the anchor between tissue layers at the point of anchoring.

  • Publication number: 20050261725
    Abstract: A medical device for vessel occlusion, the medical device including an elongated body having a distal end portion, a proximal end portion, and a lumen disposed therethrough, an balloon disposed at the distal end portion of the elongated body, the balloon in fluid communication with the lumen. An opening defined at the proximal end portion of the elongated body, the opening being in fluid communication with the balloon via the lumen, and a valve body moveably disposed at the proximal end portion of the elongated body, the valve body movable between a closed position and an open position, the valve body configured to engage a surface of the elongated body, distal to the opening, to seal the opening when the valve body is in the closed position.

  • Patent number: 6730102
    Abstract: A needle deployment device is provided. The needle deployment device comprises a body, a plurality of medical needles displaceably mounted on the body and an actuator on the body. The actuator is actuatable in response to pressurizing a fluid so as to cause the needles to displace relative to the body. It has been found that the device can be used advantageously as a suture placement device for placing suture elements through walls of vessels, and the like, during, for example, coronary artery bypass graft (CABG)surgery, or the like. Furthermore, a medical system comprising at least two bodies, a plurality of needles displaceably mounted on each body and an actuator on each body is provided. Each actuator is selectively actuatable in response to pressurizing a fluid so as to cause the needles to be displaced relative to their associated bodies. A method of performing a medical procedure is also provided.

  • Publication number: 20030120341
    Abstract: Devices and methods are provided for securing leaflets of a cardiac valve together. The subject devices include an assembly having a fastener, means for temporarily securing the fastener to the leaflets and means for permanently securing the fastener to the leaflets and means for anchoring the fastener to the heart wall. The subject methods are characterized by temporarily grasping the leaflets of a valve together at an apposition point, assessing at least one of blood flow and pressure gradient across said valve, determining whether to permanently secure the valve leaflets at said selected apposition point based upon at least one of the measured blood flow and pressure gradient, and performing one of permanently attaching the leaflets together at the apposition site or releasing the grasped leaflets. Also included are assemblies which include a subject device and a delivery device and may include a pressure monitoring member and/or a flow monitoring member.

  • Patent number: 5888205
    Abstract: The metal shell of an acetabular cup has holes that allow a surgeon to screw the shell to pelvic bone. To prevent the debris of ultra-high molecular weight polyethylene ("UHMWPE") or other plastic liner in the shell from migrating through the holes, the present invention seals each screw-receiving hole with a thin UHMWPE disc. The disc snaps into an annular groove in the hole. With the disc in place, debris from the liner does not pass through the screw holes.
