20080221654 | SYSTEMS AND METHODS FOR DELIVERING A DETACHABLE IMPLANTABLE DEVICE - Disclosed herein are various systems and methods for delivering implantable devices, such as, for example detachable embolic coils. The systems can include an embolic coil mated to a pusher wire via a detachable link comprising first and second engaging members and an expandable member or a sleeve. The expandable member or sleeve can reduce relative movement between the engaging members to inhibit premature detachment and/or jamming of the detachable link as the embolic coil is delivered through a catheter. | 09-11-2008 |
20080234723 | MICROCATHETER INTRODUCER SHEATH - The present invention includes an introducer sheath. The sheath may comprise a first proximal elongated section having a first outer diameter and a first inner diameter, and a main body elongated section having a second inner diameter and a second outer diameter, wherein the second outer diameter is larger than the first outer diameter. The sheath may further include a distal section having an outer wall that tapers from the second outer diameter of the main body elongated section to a smaller distal outer diameter. | 09-25-2008 |
20090043331 | GUIDED DETACHABLE INTERLOCK AND METHOD OF USE - Described herein are various implant delivery methods and systems that include a detachable link for connecting an implantable device and a control wire. The detachable link can include an elongate body comprising a first arm with a mating surface having a slot extending the width of the elongate body and a second arm having a mating surface that includes a extension portion adapted to mate with the slot. A guide member can extend between the first and second arms and inhibit relative transverse and/or rotational movement between the first and second arms. | 02-12-2009 |
20090099591 | Coil Anchor Systems and Methods of Use - Described herein is a coil anchor having an anchor body configured for placement within a large diameter blood vessel, wherein the anchor body includes a radially expandable sidewall, a proximal opening dimensioned to receive an embolic coil, and a distal opening dimensioned to permit blood flow within the blood vessel. The coil anchor further includes at least one coil retaining element configured to retain the embolic coil within the blood vessel while permitting blood flow within the blood vessel. | 04-16-2009 |
20090099592 | Detachable Interlock Systems and Methods of Use - Described herein are various implant delivery systems and methods of use. The systems can include an implantable medical device mated to a pusher wire via a detachable link. The user can detach the detachable link by rotating the pusher wire. For example, the detachable link can include first and second interlocking members, where the first interlocking member including a male mating surface and the second interlocking member including a female mating surface. The first and second body members can be mechanically interlocked, for example, with a pin and a slot. | 04-16-2009 |
20090138036 | BIOABSORBABLE DETACHABLE COIL AND METHODS OF USE AND MANUFACTURE - Described herein are various implant delivery methods and systems that include an implantable medical device secured to a pusher wire with biomaterial. The biomaterial is selected to controllably decouple the implantable medical device from the pusher wire after exposure to a flushing agent. | 05-28-2009 |
20100063451 | Power Injectable Port Identification - An implantable port for accessing internal body structures, the port comprises a proximal housing including an opening providing access to an interior of the port and a distal housing adapted for assembly with the proximal housing, the distal housing including a reservoir which, when the distal housing is mated with the proximal housing is in fluid communication with the opening of the proximal housing in combination with a radiopaque element in one of the proximal and distal housings, a shape of the radiopaque element identifying, when imaged, a structural characteristic of the port not otherwise identifiable visually. | 03-11-2010 |
20110087093 | VALVE CONFIGURATIONS FOR IMPLANTABLE MEDICAL DEVICES - A medical device at least partially insertable into a patient. The device comprises a catheter portion comprising a flexible tube that is at least partially insertable into the patient, and a valve portion proximal to the catheter portion. The valve portion comprises a planar flexible member comprising first and second valve portions separated from one another by an internal slit. The thickness of the planar flexible member at the internal slit is less than the thickness of the planar flexible member at any other location. | 04-14-2011 |
20120059250 | Power Injectable Port Identification - An implantable port for accessing internal body structures, the port comprises a proximal housing including an opening providing access to an interior of the port and a distal housing adapted for assembly with the proximal housing, the distal housing including a reservoir which, when the distal housing is mated with the proximal housing is in fluid communication with the opening of the proximal housing in combination with a radiopaque element in one of the proximal and distal housings, a shape of the radiopaque element identifying, when imaged, a structural characteristic of the port not otherwise identifiable visually. | 03-08-2012 |
20120095501 | Coil Anchor Systems and Methods of Use - Vessel occlusion method including the steps of positioning a coil anchor in a large diameter blood vessel, wherein the coil anchor includes a radially expandable sidewall, a proximal opening dimensioned to receive an embolic coil, a distal opening, and the coil anchor further comprising at least one coil retaining element configured to retain an embolic coil within the blood vessel. The vessel occlusion method further including the steps of expanding the coil anchor within the blood vessel; and delivering at least one embolic coil into the blood vessel, wherein the retaining element prevents the at least one embolic coil from migrating downstream of the coil anchor. | 04-19-2012 |
20120256114 | POWER INJECTABLE VALVE DESIGNS - Pressure activated valves for catheters with improved tolerance of high pressure and high flow conditions are described. Embodiments of the valve comprise a flexible membrane with one or more linear slits therethrough, and means for applying tension to the flexible membrane in-line with the linear slits. The application of tension may optionally be facilitated by structural features of both the flexible membrane and the valve housing. | 10-11-2012 |
20130190720 | BULKING AGENTS - The invention relates to bulking agents and apparatus and methods for using the disclosed bulking agents. The bulking agents can be used to treat such conditions as urinary and fecal incontinence, gastro-esophageal reflux, aneurismal blockages, and cosmetic deformities. The invention also relates to an injection method that reduces the injection pressure required to place the bulking agents. | 07-25-2013 |
