20090171300 | DELIVERY SYSTEM FOR MEDICAL DEVICE - A system for delivery of a medical device to a target site within the body of a patient includes an introducer sheath, and a delivery assembly receivable within a passageway of the sheath. The delivery assembly comprises an inner tubular and an outer tubular member. At least a distal portion of the inner tubular member has a diameter such that the medical device is receivable thereover. The outer tubular member is generally coaxial with the inner tubular member, and has a length such that the outer tubular member distal end terminates proximal to the inner tubular member distal portion. The outer tubular member has a first outer diameter at the proximal end and extends for a length of the outer tubular member to a first diameter boundary point. The outer tubular member has a gradual inward taper in the distal direction from the boundary point to a second outer diameter, and has an abrupt outward taper in the distal direction from the second diameter to the first diameter. | 07-02-2009 |

20130338703 | MEDICAL FILTERING DEVICES AND METHODS OF USE - A filter device for trapping embolic debris comprises a bag which is deployed by everting it from an end of a delivery catheter. After release from the catheter, with the assistance of a pusher member, the open end of the bag self-expands against the walls of a body lumen. In one method of removal after use, the device is withdrawn into catheter by pulling on a wire attached to the closed end of the bag. | 12-19-2013 |

20080215131 | METHOD FOR LOADING A MEDICAL DEVICE INTO A DELIVERY SYSTEM - A process to load a medical device comprising a shape memory material into a delivery system is described herein. According to one aspect, the method includes applying a force to the medical device to obtain a delivery configuration thereof, where the device is at a first temperature within an R-phase temperature range of the shape memory material during application of the force. The medical device is cooled in the delivery configuration to a second temperature at or below a martensite finish temperature of the shape memory material. The force is then removed from the medical device, and the device is loaded into a delivery system. Preferably, the medical device substantially maintains the delivery configuration during the loading process. | 09-04-2008 |
20090125093 | Method and apparatus for introducing expandable intraluminal prosthesis - A stent introducer has a delivery sheath positioned to restrain a self expandable stent. A pull wire is connected with the delivery sheath and extends through a pull wire lumen to enable remote retraction of the delivery sheath. The distal end of the pull wire lumen is associated with a region of weakness in the structure such that the region of weakness is torn on retraction of the delivery sheath. | 05-14-2009 |
20090149808 | Rapid Exchange Balloon Catheter and Method for Making Same - A rapid exchange balloon catheter having a proximal end and a distal end, said catheter comprising: a tubular metal shaft body extending from the proximal end along a majority of the total length and having an inflation lumen arranged therein, a plastics distal end portion bonded to the metal body in extension thereof, said distal end portion being provided with an inflation lumen in communication with a balloon, and a guide wire lumen, said guide wire lumen extending from a proximal side port to a distal end opening. To reduce the resistance to kinking, the metal body comprises a transitional region having reduced stiffness at the position of bonding to the plastics distal end portion compared to a more proximal position along the metal body. | 06-11-2009 |

20100222862 | Stent, Stent Graft and Other Implantable Assemblies - A stent or other implantable medical device is provided with one or more gripping shoulders which are able, when the stent is compressed onto a delivery cannula to frictionally mechanically engage the outer surface of the catheter so as to grip thereon and maintatin the position of the stent relative to the cannula during withdrawal of the covering sheath. | 09-02-2010 |
20100274226 | Deployment Catheter - A catheter for use in an endoluminal delivery assembly includes a device holding region or element on which there is provided a plurality of flexible fingers extending outwardly therefrom. The fingers act to maintain a device to be deployed in the correct position on the catheter and act to resist deformation of the device during deployment. | 10-28-2010 |

20120041537 | INTRODUCER APPARATUS - A stent introducer apparatus comprises a sheath for surrounding a stent member, with the sheath having a longitudinal slit extending from one end along at least a substantial part of the length thereof, and a sheath withdrawal device comprising a reel for winding up the sheath. A second sheath may surround the slit portion of the sheath. An intermediate guide member can smooth the withdrawal procedure and flatten the sheath before it is wound on the reel. The intermediate guide member may include at least one of a second reel or a slot-defining member. The reel may be operated by means of a gear system. A method of deploying a stent member is also provided. | 02-16-2012 |
20120059448 | EVERTING DEPLOYMENT SYSTEM AND HANDLE - A stent deployment system, handle, and method of loading of a medical device are provided. The system includes an outer catheter having an inner liner extending past the end of the outer catheter and an inner catheter disposed within the outer catheter. The inner liner is inverted and attached to the inner catheter. Relative movement between the outer and the inner catheters can urge the inner liner to peel away from the medical device. A handle is disposed at the proximal end of the outer catheter, and may include a splitter configured to slice the wall of the tubular member. The handle may also include a rotatable mechanism that can be attached to the tubular member. Rotation of the rotatable mechanism retracts a portion of the tubular member into the handle and winds the sliced portion about the rotatable mechanism. | 03-08-2012 |
