  • Patent number: 7670364
    Abstract: A system/assembly for delivery and deployment of an inflation expandable stent within a vessel, comprising a catheter having proximal and distal ends; a stent, inflation expandable from a delivery diameter to a deployment diameter, such that the delivery diameter is reduced from the deployment diameter for conforming the stent to the catheter, such that the stent, in its delivery diameter, is coaxially mounted on the catheter near the catheter distal end; an expandable inflation means coaxially mounted on the catheter axially within the stent, for expansion of the stent from the delivery diameter to the deployment diameter upon application of fluid deployment pressure to the inflation means; and a securement component coaxially mounted on the catheter, axially within the expandable inflation means, the securement component designed and adapted to provide a securement pressure to the stent in the delivery diameter to maintain the stent in position on the catheter during delivery to the deployment site.

  • Publication number: 20090234407
    Abstract: An apparatus and method can receive wireless energy using a wireless electrostimulation electrode assembly. In certain examples, at least some of the received wireless energy can be delivered as an electrostimulation to a heart. In certain examples, the wireless electrostimulation electrode can be mechanically supported at least partially using a ring formed by an annulus of a mitral valve of the heart. In certain examples, the wireless electrostimulation electrode assembly can be configured to be intravascularly delivered to an implant location within a chamber of the heart at the annulus of the mitral valve of the heart, and can fit entirely within the heart.

    Abstract: Closure devices with a rapidly dissolving anchor, systems delivering closure devices, and methods for making and using the same. An example closure device for closing an opening in a body lumen may include a plug, a rapidly dissolving anchor, and a suture coupling the plug to the anchor. The rapidly dissolving anchor may be configured to dissolve within the body lumen within about 30 days or less. At least a portion of the plug may be disposed adjacent an exterior surface of the body lumen. At least a portion of the rapidly dissolving anchor may be disposed within the body lumen.

  • Patent number: 7537580
    Abstract: A medical device comprises a catheter having at least one catheter shaft, which defines an inflation lumen for transport of an inflation fluid therethrough. The inflation fluid comprises a coolant. An expandable balloon, which has a proximal cone, distal cone, and a body region therebetween, is engaged to a distal region of the at least one catheter shaft. The balloon interior is in fluid communication with the inflation lumen. A portion of the catheter distal of the balloon body defines at least one port that is in fluid communication with the inflation lumen and the balloon interior.

  • Publication number: 20090018599
    Abstract: An implantable cardiac tissue excitation system includes an implantable pacing controller unit with a pulse generation circuit. The system also includes a lead with a lead body extending between a proximal lead end attachable to the pacing controller unit and a distal lead end configured to be implanted within a heart. A lead conductor extends within the lead body. The system also includes a transmitter assembly located near the distal lead end that is electrically connected to the pulse generation circuit through the lead conductor to wirelessly transmit pacing control information and pacing energy. The system also includes a leadless electrode assembly configured to be implanted within the heart that includes a receiver to receive the wireless transmission, a charge storage unit to store the charge energy, and an electrical stimulation circuit to deliver an electrical stimulus to cardiac tissue using the pacing control information and the charge energy.

  • Publication number: 20080021505
    Abstract: Some embodiments of a cardiac stimulation system may include a plurality of electrode assemblies that are interconnected by one or more wires while at least one of the electrode assemblies (e.g., a control electrode) wirelessly receives energy through inductive coupling with a power communication unit external to the heart (e.g., a device implanted along one or more ribs). These embodiments may provide an arrangement for efficient inductive coupling from the power communication unit to the control electrode. Also, in some circumstances, the cardiac stimulation system may eliminate the need for wired leads that extend to a location outside the heart, thereby reducing the likelihood of infection that passes along the wire and into the heart.

  • Patent number: 6036682
    Abstract: A tubular member for manufacture of medical devices insertable into body lumens. The tubular member includes an inner tubular member, and outer tubular member, and a lumen through the inner tubular member. The outer tubular member has a plurality of radiopaque segments formed of radiopaque material incorporated into the tube polymeric material. One tubular member has highly radiopaque segments separated by less radiopaque segments at intervals greater than the radiopaque segment length, such that the radiopaque segments serve as marker bands. Another tubular member has long radiopaque segments separated by less radiopaque segments at intervals less than the radiopaque segment length, such that the less radiopaque segments serve as marker bands. Marker bands can be located at either regular intervals to aid in measuring internal dimensions or at significant structural locations to aid in catheter positioning.
