Patent number: 11517339Abstract: Flexible expandable treatment devices are disclosed herein. One aspect of the present technology, for example, is directed to an expandable tubular structure formed of an interwoven strand and configured to be positioned in a blood vessel. The interwoven strand may be arranged to form a plurality of cells and a plurality of joints between adjacent cells. At least one of the joints may include a first strand slidably interlocked with a second strand, and at least one of the first strand and the second strand may bend back on itself to form a restriction that limits disengagement of the first strand and the second strand at the joint.Type: GrantFiled: May 6, 2019Date of Patent: December 6, 2022Assignee: COVIDIEN LPInventors: Brian Martin, Julio Aguilar, Nestor Aganon, Martin Dieck

Publication number: 20110213406Abstract: Vaso-occlusive devices are provided for occluding an aneurysm within the human vasculature. The vaso-occlusive device also includes a stretch-resisting member that extends through at least a portion of a lumen of the primary coil and is directly or indirectly attached to the primary coil at two locations axially separated from each other to prevent or minimize axial stretching of the primary coil. At one location, the stretch-resisting member is coupled to the primary coil via a flexible anchor assembly disposed within the lumen. In one embodiment, the anchor assembly may comprise an anchor coil and a link directly or indirectly coupled between the anchor coil and the stretch-resisting member. Alternatively, the anchor assembly may comprise a chain of twisted links.Type: ApplicationFiled: May 9, 2011Publication date: September 1, 2011Applicants: STRYKER CORPORATION, STRYKER NV OPERATIONS LIMITEDInventors: Nestor Aganon, Ann Huang, Maria Pizarro, John L.

Publication number: 20080140101Abstract: A torqueable hollow device, such as a hollow guidewire device, with a pre-determined fixed distal tip is disclosed for removing occlusive material and passing through occlusions, stenosis, thrombus, plaque, calcified material, and other materials in a body lumen, such as a coronary artery. The hollow guidewire generally comprises an elongate, tubular guidewire body that has an axial lumen. A mechanically moving core element is positioned at or near a distal end of the tubular guidewire body and extends through the axial lumen. Actuation of the core element (e.g., oscillation, reciprocation, and/or rotation) creates a passage through the occlusive or stenotic material in the body lumen.Type: ApplicationFiled: December 7, 2006Publication date: June 12, 2008Applicant: ReVascular Therapeutic, Inc.Inventors: Michael Carley, Victor Chechelski, Rudolfo Sudaria, Nestor Aganon, Christopher Huynh, Gerardo V.

Publication number: 20050261692Abstract: A medical probe comprises a probe shaft having proximal and distal shaft portions, and an operative element, such as a tissue removal element, associated with the distal shaft portion. The proximal and distal shaft portions can be positioned relative to each other in an axially aligned relationship and an axially non-aligned relationship at the interface between the shaft portions. For example, the ends of the shaft portions that engage each other can be beveled, in which case, relative rotation of the shaft portions will cause the angle between the portions to vary. Or, the shaft portions can hinge relative to each other to vary the angle between them. Thus, it can be appreciated that the probe can be introduced along a straight path via a small opening within the patient, and then the probe shaft portions can be moved relative to each other to reach off-axis tissue. The probe may have a drive shaft that extends within the probe shaft and on which the operative element is mounted.Type: ApplicationFiled: May 21, 2004Publication date: November 24, 2005Applicant: Scimed Life Systems, Inc.Inventors: Harold Carrison, Leonard Novero, Nestor Aganon

At one location, the stretch-resisting member is coupled to the primary coil via a flexible anchor assembly disposed within the lumen. The anchor assembly may comprise an anchor coil and a link or, alternatively, a chain of twisted links. In another embodiment, the anchor coil is incorporated into the primary coil by disposing the anchor coil windings between the windings of the primary coil. The vaso-occlusive assembly contains multiple detachment points at which the stretch-resistant coil(s) can be separated from the delivery device.Type: ApplicationFiled: June 27, 2002Publication date: January 1, 2004Inventors: Clifford Teoh, Nestor Aganon, Ann Huang

Patent number: 6660020Abstract: This is an implantable vaso-occlusive coil which is implanted using minimally invasive surgical techniques. It is a complex, helically wound coil made up of a primary helically wound coil which is then wound into a specific secondary shape. The secondary shape is itself a series of helical turns. At least a portion of the turns in the secondary shape form a cylindrical region and adjacent that region on at least one end is a conical region which tapers from a diameter approximating that of the central cylindrical region to a smaller diameter. The device is desirably self-forming upon exit from the distal end of a delivery catheter. Also, the conical tipped vaso-occlusive device may also utilize thrombus-enhancing filamentary material.Type: GrantFiled: November 4, 1999Date of Patent: December 9, 2003Assignee: Target Therapeutics, Inc.Inventors: Michael P.
