Patent number: 10967153Abstract: 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: GrantFiled: June 19, 2014Date of Patent: April 6, 2021Assignee: C. R. Bard, Inc.Inventors: Matthew W. Bown, David M. Butts

Patent number: 9421352Abstract: A method of providing a fluid communication path to an implanted device. The method includes positioning at least a portion of a slender pointed element within a catheter, penetrating a septum of the implanted device with the slender pointed element positioned within the catheter, positioning at least a portion of the catheter within the implanted device, removing the slender pointed element from the catheter, and retaining the at least the portion of the catheter within the implanted device.Type: GrantFiled: December 26, 2013Date of Patent: August 23, 2016Assignee: C. R. Bard, Inc.Inventors: David M. Butts, Jason R. Stats

Patent number: 8758268Abstract: A shaped guidewire for use in medical applications is disclosed. The guidewire is shaped so as to prevent inadvertent advancement of the guidewire into the corpus of a patient during use. In one embodiment, the guidewire includes an elongate body that defines proximal and distal ends. The guidewire body further defines a shaped portion that is positioned intermediate the proximal and distal ends. The shaped portion of the guidewire is at least partially composed of a shape memory material, such as nitinol, and is deflected from a longitudinal axis defined by an undeflected portion of the guidewire body. The shaped portion is disposed in one embodiment at the proximal end of the guidewire. In another embodiment, a proximal portion of the nitinol guidewire can be treated to impart malleability and enable deflection by a clinician. Methods for forming the shaped or malleable guidewire to include a deflected portion are disclosed.Type: GrantFiled: February 8, 2008Date of Patent: June 24, 2014Assignee: C. R. Bard, Inc.Inventors: Matthew W. Bown, David M. Butts

Patent number: 8641676Abstract: An exemplary infusion system for accessing an implanted device is disclosed comprising an insertion assembly, a hub comprising a sealable path configured to receive at least a portion of the insertion assembly, a flexible catheter attached to the hub and configured to receive at least a portion of the insertion assembly, and an extension tube attached to the hub. The hub may comprise a manifold element configured to provide fluid communication between the flexible catheter and the extension tube. The hub may also comprise a septum configured to seal the sealable path upon removal of the insertion assembly from the flexible catheter. The extension tube may also be configured to receive at least a portion of the insertion assembly. Exemplary methods of providing a fluid communication path to an implanted device are also disclosed.Type: GrantFiled: April 3, 2012Date of Patent: February 4, 2014Assignee: C. R.
