Publication number: 20180229019Abstract: Bypass elements for medical valves and methods of using the same are disclosed. Embodiments of the invention include an insert having a tip that is adapted to displace a valve element without penetrating it, and a lumen that fluidly communicates with a lumen of a valve housing distal to the valve element when the bypass element is engaged. Bypass elements are used, in certain embodiments, to facilitate fluid pressure and ECG signal measurements through implanted medical devices including catheters.Type: ApplicationFiled: January 10, 2018Publication date: August 16, 2018Applicant: AngioDynamics, Inc.Inventor: Raymond J.

Patent number: 9132257Abstract: A catheter shaft and methods for making and using the same. The catheter shaft may include a core portion, a cap portion, and one or more lumens. The cap portion may be disposed on or over a section of the core portion and define a region with a different exterior or interior surface characteristic. For example, the cap portion may define a lubricious region along the catheter shaft. Manufacturing the catheter shaft may include a modified co-extrusion process that incorporates a flow valve on at least one of the material supply lines so that the supply line can be regulated by a user.Type: GrantFiled: June 26, 2014Date of Patent: September 15, 2015Assignee: BOSTON SCIENTIFIC SCIMED, INC.Inventor: Raymond J. Lareau

Patent number: 8691264Abstract: Implantable or insertable medical devices are provided, which comprises: (a) a biocompatible polymer; and (b) at least one therapeutic agent selected from an anti-inflammatory agent, an analgesic agent, an anesthetic agent, and an antispasmodic agent. The medical devices are adapted for implantation or insertion at a site associated with pain or discomfort upon implantation or insertion. In many embodiments, the therapeutic will be selected from at least one of (i) ketorolac and pharmaceutically acceptable salts thereof (e.g., ketorolac tromethamine) and (ii) 4-diethylamino-2-butynylphenylcyclohexyl glycolate and pharmaceutically acceptable salts thereof (e.g., oxybutynin chloride). Also provided are uses for the implantable or insertable medical devices, which uses comprise reducing pain or discomfort accompanying the implantation or insertion of such devices. Further uses may comprise reducing microbial buildup along the device.Type: GrantFiled: February 24, 2012Date of Patent: April 8, 2014Assignee: Boston Scientific Scimed, Inc.Inventors: Jianmin Li, Danielle Conley, Weenna Bucay-Couto, Cang Duy Dao, Hamid Davoudi, Raymond J.

Publication number: 20120193255Abstract: A medical device packaging comprising a connector coupled to a longitudinal element having a lumen sized and shaped to receive an shaft of a medical device extending distally from a hub of the elongate member. The connector including a first branch having a lumen open to the lumen in the elongate member and a second branch having lumen open to the lumen in the first branch. A proximal end of the first branch being configured to mate with a distal end of a housing of the medical device to be received in the packaging. The hub of the medical device including laterally extending wings having opposing contours. The medical device including a strain relief member coupled at a distal end of the hub of the medical device.Type: ApplicationFiled: January 31, 2011Publication date: August 2, 2012Inventors: Raymond J.
