20100094257 | INVENTORY SPARING CATHETER SYSTEM - Some embodiments relate to a catheter system having a changeable or adjustable working length. The catheter system can comprise a proximal end, a distal end, and a first axial lumen configured to receive a guidewire formed through at least a portion of the catheter body. A first opening can be formed through a portion of the catheter body and be in communication with the first lumen. The sheath can be rotatable, axially movable, or otherwise changeable from at least a first position to a second position, wherein the sheath can substantially cover the first opening in the catheter body in the first position, and can substantially expose the first opening in the catheter body in the second position. | 04-15-2010 |
20100174355 | DELIVERY AND RECOVERY SHEATHS FOR MEDICAL DEVICES - A deployment control system provides controlled deployment of an embolic protection device which may include a guide wire, an expandable filter attached to the guide wire near its distal end, and a restraining sheath that maintains the expanded filter in a collapsed position. The deployment control system includes a torque control device which allows the physician to torque the guide wire into the patient's anatomy and a mechanism for preventing the guide wire from buckling as the restraining sheath is being retracted to deploy the expandable filter. A recovery control system for recovering the embolic protection device includes an inner catheter which extends within a lumen of an outer recovery sheath in a coaxial arrangement. A distal portion of the inner catheter extends beyond another recovery sheath during advancement of the recovery system into the vasculature. The recovery sheath can be advanced over the inner catheter to collapse the expandable filter. The proximal ends of the inner catheter and recovery sheath include handle portions having snap mechanisms which hold the components together as the recovery system is being advanced into the patient's vasculature. | 07-08-2010 |

20130053943 | Deformable Lumen Support Devices and Methods of Use - Lumen support devices and methods of their use are provided. A lumen support includes one or more plastically deformable cells having two stable configurations with no stable configurations between the two stable configurations. The lumen support device may be plastically deformed to other stable configurations. | 02-28-2013 |
20130131550 | GUIDEWIRE HAVING LINEAR CHANGE IN STIFFNESS - The invention is directed to a guidewire having a distal section with multiple distally tapered core segments with at least two contiguous distally tapering core segments in which the most distal tapered core segment preferably has a greater degree of taper than the proximally contiguous tapered core segment. The invention is also directed to an elongated intracorporeal device, preferably a guidewire or section thereof, that has a core member or the like with a plurality of contiguous tapered segments having taper angles that are configured to produce a linear change in stiffness over a longitudinal section of the device. The device may also have a core section with a continuously changing taper angle to produce a curvilinear profile that preferably is configured to produce a linear change in stiffness of the core over a longitudinal section of the device. | 05-23-2013 |
20130178926 | Stent Having At Least One Connecting Member Configured to Controllably Sever In Vivo - A stent may include a connector having a first portion, a second portion, and a third portion positioned between the first and second portions. The connector may be configured to interconnect axially adjacent stent segments. The connector may be further configured such that the third portion severs in response to a threshold amount of axial force, axial foreshortening, and/or cyclic loading or fatigue, in order to predispose the severance of one or more pre-configured connectors in a controlled manner to minimize any potential harm to the surrounding vasculature of a patient. | 07-11-2013 |
20130268061 | Methods Of Treatment With Drug Eluting Stents With Prolonged Local Elution Profiles With High Local Concentrations And Low Systemic Concentrations - A drug eluting stent can include a stent body having a polymeric coating with a lipophilic and/or hydrophilic element. A drug that has a bioactivity that inhibits cell proliferation can be disposed in the polymeric coating. The drug can be present in the polymer at an amount greater than or equal to about 150 μg/cm | 10-10-2013 |

20100004674 | DEVICE FOR, AND METHOD OF, BLOCKING EMBOLI IN VESSELS SUCH AS BLOOD ARTERIES - A filtering device has a directional member and filtering member disposable in a vessel (e.g. blood artery) at a position past a lesion in the direction of fluid flow. The filtering member is made from a resilient material having properties of passing the fluid while blocking the passage of emboli in the fluid. This material may be selected from a group consisting of blood filter material and a braided/woven biocompatible material with the properties specified above. The inner end of the filtering member is attached to a shaft which provides for the disposition of the members in the vessel at the position past the lesion and the withdrawal of the members from the vessel. The directional member has a length extending at least to the vessel wall. The directional member is made from a pliable and elongatable material with properties of blocking fluid and emboli passage. The directional member is deployable within the vessel by the fluid flow in the vessel and directs the fluid in the vessel and any emboli in the fluid into the filtering member. The filtering and directional members are disposed at an acute angle relative to the shaft to create a trapping pocket. Restraining wires attached to the directional member are used to collapse the directional member and draw at least a part of the directional member into an outer sheath to prevent emboli from backflowing into the vessel. | 01-07-2010 |
20110039013 | System and Method for Coating a Medical Device - A system and method allows for processing of two groups of medical devices, both groups being alternatingly spray coated within the same enclosure. The two groups repeatedly move back and forth between a spray area and a drying area which is isolated from the spray area. One group moves into the spray area as the other group moves out and into the drying area. Thereafter, the group in the spray area moves out and into the drying area and the other group moves back into the spraying area for a second coating. The alternating process may be repeated any number of times. The spray area may be located inside a sealed spray isolator enclosure and surrounded by gas discharge nozzles. | 02-17-2011 |
20140200462 | MECHANISM FOR RELEASABLY ENGAGING AN IMPLANTABLE MEDICAL DEVICE FOR IMPLANTATION - An apparatus for releasably engaging an implantable medical device during delivery includes an elongate, tubular body having an open distal end a plurality of deflectable jaw members extending distally from the distal end of the body and terminating in distal tip portions, and an actuating member slidably disposed within the body and including a distal end portion operable to prevent inward deflection of the jaw members when positioned proximate the distal tip portions. The jaw members are adapted to releasably engage an engagement feature of the implantable medical device. | 07-17-2014 |
