20100222787 | TENSION CONTROL DEVICE - A device for controlling a tensional force on an implanted elongated structure during removal of the implanted elongated structure from a body vessel of a patient via a removal tool. The removal tool is of a type that includes a sheath member having a passageway extending therethrough for receiving the elongated structure. A shaft member structured for engagement with the removal tool has a locking member disposed thereon. The locking member is constructed and arranged for selectively locking a position of the elongated structure in a manner to maintain a tension on the elongated structure, and unlocking the elongated structure to permit an adjustment of the tension. | 09-02-2010 |
20110238078 | DEVICE AND METHOD FOR POSITIONING AN IMPLANTED STRUCTURE TO FACILITATE REMOVAL - A device for adjusting a position of an elongated structure implanted in biological tissue to facilitate removal. An inner sleeve is received in an outer sleeve, and movable relative thereto. A manipulator mechanism is engaged with the inner sleeve distal end, and extends in a distal direction. The manipulator mechanism is arranged to capture the elongated structure, and to lock the elongated structure to the device upon relative movement of the sleeves. A handle is engaged with the inner sleeve, and a plunger is engaged with the outer sleeve. The plunger is engaged with the handle and movable relative thereto, wherein the outer sleeve advances distally relative to the inner sleeve to maneuver the manipulator mechanism to capture the implanted elongated structure. The position of the elongated structure may be controllably adjusted to facilitate removal thereof from the biological tissue. | 09-29-2011 |
20120310178 | VALVE ASSEMBLY - A valve assembly for controlling a flow of fluid includes a frame member and dual tubular valves arranged along the length of the frame member. The frame member includes fixed proximal and distal portions, and a rotatable intermediate portion. One valve is affixed between the proximal and intermediate portions, and the other valve is affixed between the intermediate and distal portions. The intermediate portion is selectively rotatable such that when one of the valves is in an open condition, the other valve is in a constricted condition. | 12-06-2012 |
20120323252 | TIP FOR LEAD EXTRACTION DEVICE - A tip engageable with an elongated sheath member for extracting a cardiac lead from an obstruction in a body vessel of a patient. The tip includes a tip body having a proximal end, a distal end, and a passageway extending therethrough. The tip body proximal end is engageable with the distal end of the sheath member distal end. The passageway of the tip is aligned with the passageway of the sheath such that the cardiac lead is receivable therein. The tip body distal portion has a plurality of sides extending circumferentially therearound, wherein the sides have respective ends and an inwardly directed radiused portion between the ends. | 12-20-2012 |
20130053780 | SPLITTABLE DILATOR DELIVERY SYSTEM - A delivery system for an implantable member includes an elongated dilator splittable at both the proximal and distal ends. The dilator has a tapered distal end and a pair of tabs at the proximal end. An introducer for the implantable member is received in a passageway of the dilator and extends along a length of the dilator to the tapered distal end. The introducer is arranged relative to the dilator such that upon a relative proximal movement of the dilator, the tapered distal tip of the dilator splits whereby the distal end of the introducer extends therethrough. A handle has a gripping mechanism for engagement with each tab for initiating proximal movement of the dilator relative to the introducer upon rotation of the gripping mechanism. The handle is structured for splitting the dilator proximal portion upon the relative proximal movement of the dilator. | 02-28-2013 |
20130079758 | SNARE SYSTEM - A snare for deployment or retrieval of an implantable medical apparatus. The snare includes a shaft, and a tip distal of the shaft. The tip includes an extendable member capable of self-centering the implantable apparatus during a deployment or retrieval. The extendable member is selectively receivable in the tip, distally extendable from the tip, and rotatable relative to the tip. An activatable handle is engaged with the shaft. A wire has an end engaged with the handle and an end engaged with the tip. Upon activation, the wire is urged in a proximal direction, resulting in a flexure of the tip. An elongated mechanism has a proximal portion engaged with the handle, and a distal portion engaged with the tip extendable member. The elongated mechanism is configured for selectively controlling the receiving, deploying, and rotating of the extendable member. | 03-28-2013 |
20140171960 | DEVICE FOR PREPARING AN IMPLANTED MEDICAL APPARATUS FOR EXTRACTION - A device for preparing an elongated implanted medical apparatus, such as a cardiac lead, for extraction from the body of a patient. The device includes a first handle and a second handle. At least the first handle has a surface for receiving the implanted apparatus therealong. A wire member having a first end and a second end is positioned to span a distance between the surface of the first handle, and the second handle. The wire member first end is removably engaged with the first handle, and the wire member second end is removably engaged with the second handle. The wire member is sized and arranged to enable the wire member to be wound around a length of the implanted apparatus to facilitate extraction of the apparatus with a lead extraction device. | 06-19-2014 |
20150057671 | ENHANCED OUTER SHEATH FOR EXTRACTION DEVICE - A device for extracting an elongated implanted structure from an obstruction within a vessel of a patient includes an inner sheath assembly and an outer sheath assembly. The inner sheath assembly includes an inner sheath and a tip, each having a passageway therethrough for receiving the implanted structure. The tip is configured for cutting and/or disrupting the implanted structure from the obstruction. The outer sheath assembly includes an outer sheath and a tip, each having a passageway therethrough for receiving the inner sheath assembly. The outer surface of this tip includes a plurality of raised elements circumferentially disposed therealong. The raised elements are configured for stabilizing the tissue of the vessel as the device is advanced through the vessel. | 02-26-2015 |
