Patent number: 8834499Abstract: Percutaneous methods and apparatuses for forming a venous valve from autologous tissue. A catheter having a retractable dissecting system received therein is delivered to a target location where a new venous valve is to be created. A distal balloon or other radially-expandable component mounted on the catheter is expanded against the vein wall, and the dissecting system is proximally retracted to deploy one or more dissecting components that dissect a subintimal layer of the vein wall. Radial expansion of the dissecting component(s) within the vein wall creates one or more leaflets and corresponding pocket/sinuses in the vein that collectively act as a venous valve, and/or the radially-expandable component of the catheter is subsequently collapsed such that the dissecting component(s) each pull a flap of the dissected tissue towards the vein lumen to create one or more leaflet(s) and corresponding pocket/sinuses in the vein.Type: GrantFiled: May 13, 2013Date of Patent: September 16, 2014Assignee: Medtronic Vascular, Inc.Inventors: Kevin Mauch, Maria Arreguin

Patent number: 8834500Abstract: A vein removal device includes a housing, a blade element disposed at least partially within the housing, and a hook element disposed at least partially within the housing. A cutting edge of the blade element is selectively exposed for making an incision in a patient. The blade element is disposed at one end of the housing and the hook element may be disposed at an opposite end of the housing. The blade element may be selectively exposed via actuation of a first user input that imparts a movement of the blade element relative to the housing and towards an extended position where the cutting edge of the blade element is exposed. The blade element may be biased toward the extended position via a biasing element, which may urge the blade element toward the extended position responsive to actuation of the first user input.Type: GrantFiled: March 2, 2012Date of Patent: September 16, 2014Assignee: Vascular Solutions, Inc.Inventors: Jihad Mustapha, Jose I.

Patent number: 8828046Abstract: Methods and devices are provided for controlling movement of an end effector assembly, and in particular for causing mimicking motion between a handle and an end effector assembly. In an exemplary embodiment, a surgical device is provided having a handle or actuator, an elongate shaft, and an end effector assembly coupled to a distal end of the elongate shaft. The handle or actuator is configured such that movement of the handle is mimicked, not mirrored, by the end effector assembly. The mimicking motion can be achieved using various techniques, but in an exemplary embodiment the handle is located distal to an input joint, and motion is transferred to the end effector assembly through an output joint at a distal end of the elongate shaft. The motion is preferably transferred using a mechanical transmission coupled between the input and output joints.Type: GrantFiled: October 14, 2010Date of Patent: September 9, 2014Assignee: Ethicon Endo-Surgery, Inc.Inventors: David Stefanchik, Omar J.

Patent number: 8801770Abstract: A stent, composed of linear components, comes into close contact with a tissue in vivo upon being deformed when set indwelling in vivo. The stent has linear components which are deformed to exhibit a force for maintaining dilation when the stent is set indwelling in vivo. The linear components deformed when the stent is set indwelling in vivo are composed of non-biodegradable metallic linear components and a plurality of biodegradable material-made linear components which are bonded to the non-biodegradable metallic linear components. Furthermore, when set indwelling in vivo, the stent exhibits the force for maintaining the dilation owing to both the non-biodegradable metallic linear components and the biodegradable material-made linear components. After a predetermined period of time, biodegradation of the biodegradable material-made linear components proceeds, which results in a lowering of the force for maintaining the dilation.Type: GrantFiled: March 26, 2010Date of Patent: August 12, 2014Assignee: Terumo Kabushiki KaishaInventors: Kito Takayuki, Goto Hiroki
