In one embodiment, the circumference of the implant is substantially similar both before and after modification of the implant length. In another embodiment, the implant includes a plurality of strut sections interconnected by bridges which are capable of the deformation along the longitudinal axis of the implant.Type: GrantFiled: April 16, 2018Date of Patent: June 23, 2020Assignee: COVIDIEN LPInventors: Richard S.

Patent number: 10660648Abstract: A vascular occlusion device includes a braided filament mesh structure defining a longitudinal axis. The mesh structure has a relaxed configuration in which it has an axial array of radially-extending occlusion regions, each of which has a proximal side and a distal side meeting at a peripheral edge, the sides of each occlusion region forming a first angle relative to the longitudinal axis. Each occlusion region is axially separated from the adjacent occlusion region by a reduced-diameter connecting region. The mesh structure is radially compressible to a compressed state in which it is deployed intravascularly to a target site through a catheter. Upon deployment, the device radially expands to a constrained configuration in which the peripheral edges of the occlusion regions engage the vascular wall, and the sides of the occlusion regions form a second angle relative to the longitudinal axis that is smaller than the first angle.Type: GrantFiled: June 25, 2019Date of Patent: May 26, 2020Assignee: Inceptus Medical, LLCInventors: Paul Lubock, Richard Quick, Robert Rosenbluth, Brian J.

Patent number: 10646109Abstract: A medical device is provided that comprises: (i) an expandable capsule that can be swallowed by a patient and positioned to a target tissue within the patient, (ii) an endoscope attached to the capsule for obtaining an image of the target tissue at a wavelength of interest, and (iii) a thin tube or wire configured to position the device to the target tissue. The thin tube or wire is expandable. The capsule can be swallowed in stages to position the device at different locations within the gastrointestinal tract. The thin tube or wire can deliver electromagnetic radiation for visualization of the target tissue. The thin tube or wire can provide a passage of a biopsy device for access to the target tissue. In some instances, the capsule comprises a band which rotates around the capsule to clean the capsule. In some instances, the capsule collects multispectral or hyperspectral information.Type: GrantFiled: July 19, 2005Date of Patent: May 12, 2020Assignee: HYPERMED IMAGING, INC.Inventors: Jenny E. Freeman, Derek Brand, Michael J. Hopmeier

Patent number: 10582998Abstract: The disclosure describes a method including manufacturing a shape memory polymer fabric with a collection of shape memory polymer fibers such that the resulting shape memory polymer fabric has a glass transition temperature of greater than 50 degrees centigrade. The method further includes training the shape memory polymer fabric with a pre-determined percentage of strain between an expanded shape and a contracted shape. The method further includes preparing a portion of the shape memory polymer fabric into a shape that is sized to cover two portions of a ruptured soft tissue of an animal with a mean body temperature below 40 degrees centigrade while the fabric has the predetermined percentage of strain stored in the expanded shape.Type: GrantFiled: October 17, 2012Date of Patent: March 10, 2020Assignee: MEDSHAPE, INC.Inventors: David Safranski, Kathryn Smith, Jack C. Griffis, III

Patent number: 10524938Abstract: A production method for a medical linear member is provided which is not abraded upon production and which includes a flat shape in a cross section. The method includes the steps of: forming a first spiral body (1) of an oval shape in a horizontal section by spirally winding a base body (3), in which a plurality of wires (2) formed of a shape-memory alloy is arrayed, around a winding core (4); subjecting the first spiral body (1) to first shape-memory treatment; cutting the first spiral body (1) into a first predetermined length; forming a second spiral body (5) of a flat shape in a horizontal section by compressing the first spiral body (1) in a direction along a short diameter; subjecting the second spiral body (5) to second shape-memory treatment; and removing the winding core (4) from the second spiral body (5).Type: GrantFiled: January 29, 2016Date of Patent: January 7, 2020Assignee: SYNTEC CORPORATIONInventor: Kazumi Akatsu
