Publication number: 20170239444Abstract: The present disclosure provides a catheter grip device that secures to a catheter shaft and provides easier manipulation of the catheter shaft for the user. For example, the catheter shaft, such as for an Electrophysiology catheter, may insert into a patient's blood vessel. From here, the user, such as the physician, may need to manipulate, re-position, rotate, or otherwise maneuver a distal end of the catheter shaft while inserted inside the patient's blood vessel. In this regard, by the catheter grip being securely attached to the catheter shaft, the user is able to manipulate, rotate, etc. the catheter shaft by rotating and manipulating the catheter grip. The catheter grip reduces strain on the various muscles of the user's hand, and also provides more accurate manipulation of the catheter shaft.Type: ApplicationFiled: February 23, 2016Publication date: August 24, 2017Inventor: Steven Parker

Publication number: 20170239447Abstract: A neurovascular catheter extension segment is provided, such as for distal neurovascular access or aspiration. The neurovascular catheter extension segment includes 1) an elongate flexible control wire having a proximal end and a distal end and 2) a tubular extension segment having a side wall defining a central lumen carried by the distal end of the control wire. The side wall of the tubular extension segment includes a tubular inner liner, a tie layer separated from the lumen by the inner liner, a helical coil surrounding the tie layer, and an outer jacket surrounding the helical coil. The extension segment may be introduced into the proximal end of a neurovascular catheter and advanced distally to extend beyond the catheter and thereby extend the reach of the catheter.Type: ApplicationFiled: February 27, 2017Publication date: August 24, 2017Inventors: Yi Yang, Fred Khosravi, Lisa M.

Publication number: 20170239449Abstract: Some embodiments of a medical device anchor system include an anchor device that secures a medical instrument (such as a catheter or the like) in place relative to a skin penetration point using subcutaneous anchors. In some implementations, the anchor device can be installed using a technique in which the subcutaneous anchors undergo relatively little or no flexing when being inserted through the skin into the subcutaneous region between the skin and underlying muscle tissue which may be occupied by fatty tissue.Type: ApplicationFiled: May 5, 2017Publication date: August 24, 2017Inventors: Michael S. Rosenberg, Mark R. Christianson, Kyle P. Taylor, Andrew T. Forsberg

Publication number: 20170239450Abstract: Disclosed herein are embodiments of segmented metallic guidewires that are suitable for MRI catheterization. Disclosed guidewires comprise a plurality of short conductive metallic segments that individually are short enough such that they do not resonate during MRI. The conductive segments are electrically insulated from each other and mechanically coupled together end-to-end via connectors, such as stiffness matched connectors, to provide a sufficiently long, strong, and flexible guidewire for catheterization that is non-resonant during MRI.Type: ApplicationFiled: October 19, 2015Publication date: August 24, 2017Applicant: The United States of America, as represented by the Secretary, Department of Health and Human ServInventors: Ozgur KOCATURK, Burcu BASAR, Robert J. LEDERMAN

Publication number: 20170239451Abstract: An expandable tissue dilator for dilating tissue around a spinal column includes a housing and a shaft at least partially positioned distally of the housing and adapted to pierce a tissue around the spinal column. An expandable member attached to the housing expands around a portion of the shaft to dilate the pierced tissue in a single-pass dilation resulting in a reduction of any traumatic impingement of nerves or muscle tissue and reduction in procedure time.Type: ApplicationFiled: February 23, 2016Publication date: August 24, 2017Inventor: Andrew Berkowitz

Publication number: 20170239453Abstract: Provided is a treatment method and a medical device that can intentionally and locally administer a drug to a lesion area appearing in a narrow blood vessel such as a retinal blood vessel and a spinal blood vessel. The treatment method has an introduction step of introducing a medical elongated body having a drug holder for holding a drug into a living body, an arrangement step of arranging the drug holder at a treatment target inside the living body, and a discharge step of discharging the drug to the treatment target by releasing the drug held by the drug holder.Type: ApplicationFiled: February 3, 2017Publication date: August 24, 2017Inventors: Taisei KAWAKITA, Tomoji MARUYAMA, Ryota TANETANI, Hiroyuki TAGUCHI
