Publication number: 20220273475Abstract: An attachment mechanism for a medical implant system may include a first part fixedly attached to a distal end of an elongate shaft, the first part having a first longitudinal lumen configured to slidably receive a release wire disposed within the elongate shaft, and a second part fixedly attached to a proximal end of a medical implant, the second part having a second longitudinal lumen configured to slidably receive the release wire. A tubular distal portion of the second part may include an engagement feature configured to non-releasably engage the second part with the medical implant.Type: ApplicationFiled: April 8, 2022Publication date: September 1, 2022Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Nicholas Lee Tassoni, Kelsey Rae Cooper, Thomas P. Jancaric, John D. Kroeger, Eric Dinges, Reggie Roth, John L. Teschendorf, David B. Morris

Patent number: 9585686Abstract: An infusion flow guidewire and a system including an infusion flow guidewire. The minimal cross section flexible infusion flow guidewire includes a nitinol hypotube, a flexible tip having a closed distal end, a coil, a core wire and at least one distally located rearwardly directed jet orifice for infusion of fibrinolytics and for introduction of high pressure fluids for maceration and rearwardly directed flow of thrombus debris located in tortuous small sized vessels. Apparatus, some of which is removably attachable, is provided in the system for grasping members of the invention for rotational torqueing and for longitudinal actuation along and within the vasculature.Type: GrantFiled: December 9, 2013Date of Patent: March 7, 2017Assignee: BOSTON SCIENTIFIC LIMITEDInventors: John Riles, Douglas J. Ball, Michael J. Bonnette, Eric J. Thor, John L. Teschendorf, Hieu V. Le

Patent number: 8657777Abstract: Catheters including guidewire tubes having a limited length and methods of using the catheters are described. The catheters may be delivered over guidewires in procedures that are commonly referred to as rapid-exchange delivery. In some embodiments, the catheters may be miniature flexible thrombectomy catheters that may be used to remove thrombus or other unwanted material from a body blood vessel or other small regions of body cavities in which the distal portion of the catheter has smaller external dimensions than the larger proximal portion.Type: GrantFiled: January 14, 2013Date of Patent: February 25, 2014Assignee: Bayer Medical Care Inc.Inventors: Debra M. Kozak, Michael J. Bonnette, Eric J. Thor, David B. Morris, John L. Teschendorf, Douglas J. Ball, Michael Schrom, Stephen E. Weisel
