Publication number: 20140303600Abstract: A method of treating a patient includes providing a guidewire having an elongate body defining a proximal end and a distal end, the elongate body including a shapeable portion disposed proximate the proximal end, the shapeable portion being malleable so as to be shaped into a shape and remain in the shape until reshaped. The distal end of the elongate body is advanced into a vasculature of the patient. The shapeable portion of the elongate body is shaped into a first shape that prevents advancement of the guidewire further into the vasculature of the patient.Type: ApplicationFiled: June 19, 2014Publication date: October 9, 2014Inventors: Matthew W.

Patent number: 8845618Abstract: An anti-clog suction tip apparatus includes a suction tip having a suction opening and an interior defining a suction channel. An ejection wire channel extends to a wire exit opening into the suction channel that is located proximate the suction opening. An ejection wire including a ball tip at an end thereof occupies the ejection wire channel and is transitionable between a retracted configuration and an advanced configuration such that, in the retracted configuration, the ejection wire including the ball tip is retained within the ejection wire channel and does not obstruct suctioning of debris through the suction channel; and in the advanced configuration, the ball tip of the ejection wire does not extend more than three millimeters beyond the suction opening.Type: GrantFiled: November 4, 2013Date of Patent: September 30, 2014Assignee: H & M Innovations, LLCInventors: Robert Sean Hensler, Thomas Eric Melin

Publication number: 20140288533Abstract: A guide wire has a wire body; and a distal side coating layer that covers a distal portion of the wire body. The guide wire has a cylindrical member that has an outer diameter substantially the same as an outer diameter of a proximal portion of the distal side coating layer, that encircles a portion of the wire body and that has a distal portion positioned proximate the proximal portion of the distal side coating layer; and a joint member that is disposed at a proximal side of the cylindrical member and joins the cylindrical member and the wire body. The joint member has a gradually decreasing outer diameter portion whose outer diameter gradually decreases toward a proximal side of the wire body, and an outer peripheral surface of the cylindrical member has a surface continuous with the gradually decreasing outer diameter portion.Type: ApplicationFiled: June 6, 2014Publication date: September 25, 2014Inventors: Yutaka TANO, Yousuke NABESHIMA

Publication number: 20140276393Abstract: In a catheter system and method for assembly thereof, one end of a catheter shaft is inserted into a connector for a handle, with the connector being generally tubular and having a channel extending longitudinally therethrough. At least a lengthwise segment of the channel is sized in transverse cross-section greater than an outer cross-section of the catheter shaft. The catheter shaft is inserted into the channel of the connector such that the catheter shaft is spaced from the connector within the lengthwise segment of the channel. Adhesive is directed through a port in the sidewall of the connector into the lengthwise segment of the channel to flow circumferentially about the catheter shaft within the channel. The adhesive is allowed to cure and the connector (with the catheter adhered thereto) is retained on the handle.Type: ApplicationFiled: March 7, 2014Publication date: September 18, 2014Inventors: Kevin Gin Park, Emily Michelle Gordon, James Paul Goodman, John Francis Arnold, Bradley C.
