Patent number: 8911464Abstract: A puncture apparatus includes a puncture needle for puncturing living body tissue, an axial portion, a puncture member including an interlock portion interlocking the puncture needle and the axial portion, an elongated urethral-insertion member insertable into the urethra, an elongated vaginal-insertion member insertable into the vagina; and a supporting member supporting the puncture member, the urethral-insertion member and the vaginal-insertion member. The distal end of the puncture needle includes a sharp needle tip, and the needle is bent in an arc shape centered on the axial portion. The axial portion is freely rotatable on the supporting member, and the supporting member restricts the positional relation between the puncture member and the urethral-insertion member such that when the puncture member rotates and punctures the living body tissue, the needle tip passes a far-position side from the center of the puncture needle compared with the urethral-insertion member or an extended line of such member.Type: GrantFiled: March 15, 2013Date of Patent: December 16, 2014Assignee: Terumo Kabushiki KaishaInventors: Masakatsu Kawaura, Shigeki Ariura

Patent number: 8870895Abstract: A medical retrieval device used to remove objects such as urinary and biliary calculi from the body comprising a handle assembly with an independent rotational means, a sheath, and an object entrapping assembly. In preferred embodiments, the handle assembly comprises a longitudinally stationary base portion with a handle base and a rotating means and a thumb slide actuation means located between the distal and proximal ends of the handle base portion. Actuation of the thumb slide relative to the handle base causes the object entrapping assembly to be actuated between the open and closed positions. Rotation of the rotating means relative to the handle base causes precise rotation of the object entrapping assembly. The thumb slide actuation means and rotating means are separate and independent of each other, preventing inadvertent adjustment of the degree of actuation during rotation and preventing inadvertent adjustment of rotational position during actuation.Type: GrantFiled: September 19, 2011Date of Patent: October 28, 2014Assignee: Annex Medical, Inc.Inventor: Mark R. Bilitz

Patent number: 8858619Abstract: A system for percutaneously inserting a prosthesis containing a biological replacement for a defective valve into an implantation site through a body lumen. The system contains a balloon catheter upon which a collapsable stent containing a venous valvular replacement is mounted. A protective shield is slidably mounted upon the catheter that is movable between a closed position over the balloon and an open position wherein the balloon can be inflated to expand the stent. A central lumen runs through the catheter that is formed of stainless steel. The central lumen provides a one to one torque ratio between the proximal end of the catheter and the distal end to enhance the steerability of the catheter. The vein of the replacement is reduced in thickness between 50% and 90% of its original size thereby considerably reducing the size of the replacement package when the stem is collapsed upon the balloon of the catheter.Type: GrantFiled: May 12, 2006Date of Patent: October 14, 2014Assignee: Medtronic, Inc.Inventors: Allen J. Tower, Philipp Bonhoeffer, Michael L. Martin

Patent number: 8845674Abstract: An implant configured for ingestion by a patient. After the implant has been swallowed by the patient and is disposed within the target location, e.g. the patient's stomach, an inflation subcomponent causes the implant to expand from a compact delivery state to an expanded, volume-occupying, deployed state. In the deployed state the implant creates a sensation of satiety in the patient stomach and thereby aids in limiting food intake and obesity. After a predetermined time a deflation subcomponent is actuated and the implant reduces in size so as to allow it to pass through the remainder of the patient's digestive track. The device may further incorporate tracking and visualization subcomponents, as well as pharmaceutical delivery subcomponents.Type: GrantFiled: April 23, 2012Date of Patent: September 30, 2014Assignee: Obalon Therapeutics, Inc.Inventors: Mark C. Brister, Nelson Quintana, Kaushik A. Patel, Neil R. Drake, Antonio C. Llevares, Dubravka Markovic, Andrew P. Rasdal, Amy D. L. VandenBerg
