Publication number: 20230404486Abstract: Embodiments described relate to a medical device including an invasive probe such as a guidewire that, when inserted into a duct (e.g. vasculature) of an animal (e.g., a human or non-human animal, including a human or non-human mammal), may be used to aid in diagnosing and/or treating a lesion of the duct (e.g. a growth or deposit within vasculature that fully or partially blocks the vasculature). The invasive probe may have one or more impedance sensors to sense characteristics of the lesion, including by detecting one or more characteristics of tissues and/or biological materials of the lesion. There is further described a method of assembling such a medical device.Type: ApplicationFiled: February 3, 2023Publication date: December 21, 2023Applicant: Sensome SASInventors: Bruno Carreel, Edward I.

Patent number: 10869956Abstract: An interventional catheter assembly comprising a catheter for insertion and guidance to a target site in a body lumen or a cavity and an operating head mounted in proximity to a distal end of the catheter and comprising a system for removing obstructive material from the target site is provided. In certain embodiments, the catheter assembly includes at least one aspiration port located proximal to the operating head that communicates with a first sealed lumen for withdrawing fluids and obstructive material from the target site. The catheter assembly may also include at least one liquid infusion port that communicates with a second sealed lumen for supplying fluid to a location in proximity to the target site. Kits including the interventional catheter assembly with an aspiration and/or infusion conduit are also provided.Type: GrantFiled: June 6, 2018Date of Patent: December 22, 2020Assignee: BOSTON SCIENTIFIC LIMITEDInventors: Casey Torrance, Kate Walsh, Jared Salstrom, Scott Youmans, Edward I.

Patent number: 10149698Abstract: An interventional catheter assembly has an operating head and catheter system that are inserted and navigated within a patient's body while an operator controls the system externally of the operating head. An operating head is positioned at or near a distal end of the catheter system and coupled to a drive shaft and drive system for rotation. A guidewire brake control system interrupt prevents the drive system from being actuated when the guidewire brake is in a released position, and a selectable guidewire brake interrupt override control permits an operator to translate and/or rotate the drive shaft and operating head while the guidewire is simultaneously moved. This allows withdrawal of the guide wire and the operating head from the target site while rotating the operating head.Type: GrantFiled: February 10, 2015Date of Patent: December 11, 2018Assignee: BOSTON SCIENTIFIC LIMITEDInventors: Edward I. Wulfman, Casey Torrance, Brian Cran, Scott Youmans

Patent number: 10092313Abstract: A tubular structure comprising multiple overlapping layers surrounding a lumen has flexibility and structural integrity by allowing portions of the layers to slip relative to each other. One embodiment includes a support layer having a wired coil, braid or weave support element underlies at least one overlying layer. The support layer is fixed to the overlying layer at a bonding point and the remaining portion of the support layer is not fixed to the overlying layer, i.e. “free portion”. The support layer is permitted to slip at the free portion of the support layer, relative to the overlying layer. Further flexibility may be provided by a coil element of the support layer having substantial gaps between the loops of the coil to impart high flexibility of the tubular structure.Type: GrantFiled: March 10, 2004Date of Patent: October 9, 2018Assignee: BOSTON SCIENTIFIC LIMITEDInventor: Edward I Wulfman

In certain embodiments, the catheter assembly includes at least one aspiration port located proximal to the operating head that communicates with a first sealed lumen for withdrawing fluids and obstructive material from the target site. The catheter assembly may also include at least one liquid infusion port that communicates with a second sealed lumen for supplying fluid to a location in proximity to the target site. Kits including the interventional catheter assembly with an aspiration and/or infusion conduit are also provided.Type: ApplicationFiled: June 6, 2018Publication date: October 4, 2018Applicant: BOSTON SCIENTIFIC LIMITEDInventors: CASEY TORRANCE, KATE WALSH, JARED SALSTROM, SCOTT YOUMANS, EDWARD I.

Publication number: 20180235790Abstract: A convertible catheter for use as a nephrouretheral stent, biliary stent, or other structure for maintaining patency of a bodily lumen is disclosed. After initial implantation, the proximal portion of the convertible catheter extending out from the body may simply be removed. A simple action at the catheter hub allows this proximal portion to be removed, leaving behind the implanted stent within the patient.Type: ApplicationFiled: February 21, 2018Publication date: August 23, 2018Inventors: Harry R. SMOUSE, Kent C. B. STALKER, Timothy H. WILLIAMS, Edward I. WULFMAN
