Publication number: 20180185620Abstract: A medical instrument such as a guidewire that is designed to have controlled torque transmission along its length. Specially treated areas are placed in selected and equal areas along the entire length of the elongated shaft of the medical instrument, and are separated from one another by untreated areas. This process ensures that any torque is transmitted distally, in a smooth manner, regardless of the guidewire position, thus resulting in a substantial reduction in whipping. In one embodiment, a stainless steel guidewire is utilized, and is subjected to annealing heat treatment in selected areas. This annealing process creates a mandrel that has repeated temper properties along its length. Torque applied at one end of this mandrel is transmitted to the opposite end in an even and controlled manner, even when the mandrel is formed into a loop.Type: ApplicationFiled: August 14, 2017Publication date: July 5, 2018Applicant: BOSTON SCIENTIFIC SCIMED INC.Inventors: John A. Griego, Patrice A. Weststrate

Patent number: 8439869Abstract: A method for percutaneously implanting a medical catheter, such as a gastrostomy feeding tube, and a medical catheter implanting assembly. In one embodiment, the implanting assembly includes a gastrostomy feeding tube, an inner sheath and an outer sheath. The feeding tube has an internal bolster integrally formed at its distal end. The inner sheath includes a bore extending distally from its proximal end to a point prior to its distal end and a transverse window communicating with the bore. The outer sheath includes a proximal end, a distal end and a longitudinal bore. The outer sheath is inserted over the inner sheath, and the feeding tube is inserted into the inner sheath, with the internal bolster being folded and tucked into the window and retained therein by the outer sheath. Movement of the outer sheath relative to the inner sheath to expose the window allows the bolster to decompress.Type: GrantFiled: September 21, 2011Date of Patent: May 14, 2013Assignee: Boston Scientific SCIMED, Inc.Inventors: Patrice A.

Publication number: 20130110079Abstract: An access needle well-suited for percutaneous implantation in a body lumen, such as the stomach or the jejunum. In one embodiment, the access needle comprises a cannula, a needle, a retractable stopper and a spreader. The cannula is a tubular member having a proximal end, a distal end, a lumen and a pair of side windows providing access to the lumen. The needle is slidably mounted within the cannula lumen and comprises a needle stem and a needle handle, the needle stem having a proximal end, a distal end and a longitudinal lumen, the needle handle extending outwardly from the needle stem proximate to the proximal end thereof. The stopper is coupled to the needle stem for translational movement, the stopper comprising a pair of outwardly-biasing wings removably insertable through the side windows for engaging an interior surface of a patient. The spreader is mounted within the cannula and spreads the wings outwardly as the wings are inserted out the side windows.Type: ApplicationFiled: December 19, 2012Publication date: May 2, 2013Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventor: Patrice A.

Patent number: 8308713Abstract: A medical catheter assembly including a multi-piece connector. In one embodiment, the medical catheter assembly is a PEG implanting assembly comprising a tubular dilator and a silicone feeding tube having an internal bolster at its rear end. The assembly also comprises a multi-piece connector comprising an inner ring, a fitting and an outer ring. The inner ring has an outer diameter greater than the inner diameter of the feeding tube and is coaxially disposed within the feeding tube by a friction-fit. The fitting comprises a front portion, an intermediate portion and a rear portion, the intermediate portion including a shoulder having an outer diameter greater than the inner diameter of the feeding tube. The front portion of the fitting is inserted through the rear end of the dilator and is secured to the dilator by a plurality of barbs.Type: GrantFiled: March 23, 2009Date of Patent: November 13, 2012Assignee: Boston Scientific Scimed, Inc.Inventors: Changqing Li, Gary Wood, Herbert Alan Sundheimer, Laddvanh Bouphavichith, Patrice A.

Patent number: 8221389Abstract: An adaptor for use with a medical catheter comprises a housing having a first tubular channel with a first longitudinal axis, a dial having a second tubular channel with a second longitudinal axis, and an adaptor fitting removably connected to the second tubular channel. The dial is rotatable between an open position and a closed position when the adaptor fitting is connected thereto. In the open position the first tubular channel is fluidly connected to the second tubular channel, and in the closed position the first tubular channel is not fluidly connected to the second tubular channel. The dial may be configured such that it is not rotatable between the open position and the closed position when the adaptor fitting is not connected thereto.
