  • Patent number: 8197442
    Abstract: A system is provided that includes an elongated introducer navigable through body vessels of a human subject and a pusher component for incorporation within the introducer. The pusher component includes a tubular portion with a slotted section. A radiopaque marker is secured to at least a portion of the slotted section such that an outer surface of the radiopaque marker is substantially flush with an outer surface of the tubular portion immediately proximal and/or immediately distal the radiopaque marker. According to a method of manufacturing such a component, the slotted section is formed by a laser cutting operation and a pre-assembly radiopaque marker member is crimped onto the slotted section.

  • Patent number: 8192366
    Abstract: A pressure sensing catheter having a pressure sensor and an antenna that is coupled to the pressure sensor, e.g., by a connector, are provided. The pressure sensor can be adapted to measure a pressure surrounding the catheter, and the antenna can be adapted to telemetrically communicate the measured pressure to an external device. In an exemplary embodiment, the antenna, pressure sensor, and/or connector are hermetically sealed, e.g., by the catheter and/or a coating, to prevent the antenna, pressure sensor, and connector from coming into contact with fluid, thereby allowing the catheter to be permanently implanted or otherwise used for long term use. Exemplary methods for manufacturing and using pressure sensing catheters are also provided.

  • Patent number: 8182523
    Abstract: An expandable stent and delivery system is provided for treating body vessel defects, such as partially occluded blood vessels and aneurysms. The delivery system includes a core member having a non-cylindrical retraction member with extending portions configured to extend between struts of the stent. The stent includes enlarged anchor members that cooperate with the retraction member to secure the stent to the core member for movement within a delivery catheter and deployment to a body vessel defect. The extending portions provide a greater contact area than would be possible with a cylindrical retraction member, which is especially beneficial when retracting a partially deployed stent into the catheter.

  • Patent number: 8147480
    Abstract: A therapeutic agent delivery system that includes a catheter having a proximal end and an opposite distal end. The catheter has a body with a lumen defined therein. The body of the catheter includes a non-bulbous region having a substantially uniform outer diameter and a bulbous region made from an elastically deformable material. While in a first state the bulbous region has a maximum outer diameter greater than the substantially uniform outer diameter of the non-bulbous region; and while in a second state the maximum outer diameter of the bulbous region is reduced relative to that while in the first state.

  • Patent number: 8140173
    Abstract: An anchor system for securing a lead to a patient's skull is disclosed. The lead is of the type that passes through a burr hole created in the patient's skull and includes a distal end which is implanted within the patient's brain at a target site. The anchor, according to a first embodiment of the invention includes a stem, an integrally formed rim plate, and a peripheral clamping structure. The clamping structure is adapted to receive and snugly hold a portion of the lead. The stem is sized and shaped to fit within the burr hole, leaving the rim plate positioned flush with the patient's skull. A flared passage is provided within the stem and rim plate so that the lead may pass through the stem and into the rim plate, at which point the lead follows the contours of the flared passage and communicates with the peripheral clamping structural.

  • Patent number: 8133252
    Abstract: A reattachable introducer and method of using such introducer is disclosed for inserting an embolic coil deployment system into the tortuous vasculature of the human brain for placing an embolic coil within an aneurysm. The introducer includes a sheath having a lumen, a side opening and a longitudinal slit and includes a cylindrical sleeve slideably disposed about the sheath. A deployment catheter with a conical expander member is slideably disposed through the side opening of the sheath and through the lumen of the sheath. The conical expander member detaches the introducer from the deployment catheter through the longitudinal slit of the sheath, while the cylindrical sleeve reattaches the introducer to the deployment catheter through the longitudinal slit.

  • Publication number: 20120015006
    Abstract: Flowable graft materials are provided which comprise collagen powder and a liquid in an amount sufficient to impart a flowable consistency to the material. The graft materials are sufficiently formable and pliable so as to provide both superior contact with and easier access to a surgical site than typical, more rigid grafts such as collagen sheets. These flowable materials may also be in a fluidized, paste-like and/or gel-like state and may be moldable and/or ejectable. The flowable collagen materials reduce and/or eliminate post implantation problems associated with other materials, e.g. synthetic dural sealants (hemostasis products), such as product swelling after application and implantation. The flowable graft materials are particularly useful as a dural graft.

  • Patent number: 8088092
    Abstract: A valve for use in a shunt system to drain fluid from one part of a patient's body to another is provided. In an exemplary embodiment, the valve is operable at a threshold pressure that is selectively adjustable up to at least about 400 mm H2O at increments in the range of about 10 mm H2O to 40 mm H2O. The ability of the valve to operate at a high threshold pressure and to be adjusted at relatively small increments renders the valve particularly advantageous for use in younger hydrocephalus patients. In particular, the operating pressure of the valve can be gradually limited in small increments over a period of time to slowly force the patient's own resorption system to circulate cerebrospinal fluid. At high operating pressures of at least about 400 mm H2O shunt independence can be achieved thereby allowing the shunt to be successfully removed.

  • Patent number: 8062325
    Abstract: An implantable medical device detachment system is provided with a carrier member having a compressible portion at a distal end thereof. The compressible portion is moved to a compressed condition to allow an engagement member of the system to releasably engage an implantable device, such as an embolic coil. The carrier member and associated implantable device are fed through a body vessel to a target location, where the device is disengaged from the engagement member. The compressible portion then moves from the compressed condition to an elongated condition to completely separate the implantable device from the engagement member.
