Patent number: 9867522Abstract: Various apparatuses to attach a first medical device to a second medical device are described that allow the physician to grasp only a single device while the other device remains securely attached to the one being grasped. The apparatuses, once they are attached to the first medical device, are designed to be easily and quickly attached and detached to a second medical device, normally only requiring the use of one hand. Furthermore, the apparatuses oftentimes include a base that can easily couple and decouple from the portion that is attached to the second medical device so that if the need arises to separately use the second medical device, it can be decoupled from the first medical device without completely removing the apparatus from the second medical device.Type: GrantFiled: January 4, 2017Date of Patent: January 16, 2018Assignee: Boston Scientific Scimed, Inc.Inventors: John B. Golden, John O. McWeeney, Christopher A. Benning, Robert Castoldi, John F. Howard, Brian Intoccia, Gary Kappel, William Lucas Churchill

Publication number: 20180001057Abstract: The present disclosure provides an access system having a maneuverable catheter assembly configured for providing access to and navigating a desired vessel for subsequent treatment thereof. The access system includes an adjustable delivery handle assembly and an access catheter subassembly having a maneuverable access catheter configured to be delivered to desired site (e.g., within duodenum) to assist in treatment of a condition (e.g., drainage of a bile ducts via Endoscopic Ultrasound Guided Biliary Drainage (EUS-BD) techniques). The access catheter includes at least a distal section having an adjustable portion along a length thereof configured to transition to a pre-defined arcuate shape to provide directional control over the distal end of the catheter as it is navigated through a vessel (e.g., bile duct). The handle assembly includes additional elements configured to allow a clinician to maneuver and manipulate the distal end of the access catheter.Type: ApplicationFiled: September 19, 2017Publication date: January 4, 2018Inventor: John O.

Patent number: 9844362Abstract: The present disclosure generally relates to a biopsy needle configured to maximize tissue sampling yield and collect a cohesive unit of sampled tissue. The biopsy needle includes an elongate tubular body comprising a lumen extending therethrough from a proximal open end to a distal open end of the body. The distal end includes first and second tip portions extending therefrom and formed on opposing sides of the needle body. The first tip portion generally extends further from the distal end than the second tip portion, resembling a staggered configuration, resulting in an increased surface area of multiple cutting edges formed between the first and second tip portions on either side of the needle body. Additionally, each of the first and second tip portions defines a penetrating point configured to pierce the tissue to be sampled and further direct sampled tissue towards the lumen of the body to be excised by the cutting edges upon contact therewith.Type: GrantFiled: January 13, 2015Date of Patent: December 19, 2017Assignee: Covidien LPInventors: John O.

Publication number: 20170231475Abstract: Several embodiments of the present invention are generally directed to medical visualization systems that comprise combinations of disposable and resuable components, such as catheters, functional handles, hubs, optical devices, etc. Other embodiments of the present invention are generally directed to features and aspects of an in-vivo visualization system that comprises an endoscope having a working channel through which a catheter having viewing capabilities is routed. the catheter may obtain viewing capabilities by being constructed as a vision catheter or by having a fiberscope or other viewing device selectively routed through one of its channels. The catheter is preferably of the steerable type so that the distal end of the catheter may be steered from its proximal end as it is advanced with the body. A suitable use for the in-vivo visualization system includes but is not limited to diagnosis and/or treatment of the duodenum, and particularly the biliary tree.Type: ApplicationFiled: May 3, 2017Publication date: August 17, 2017Applicant: Boston Scientific Scimed, Inc.Inventors: John O.
