摘要： A method of minimally invasively replacing a cardiac valve of a patient including inserting a delivery catheter intraluminally, inserting a valve resecting instrument intraluminally through the delivery catheter to a position adjacent the cardiac valve of a patient, manipulating the valve resecting instrument to resect the cardiac valve, removing the resected valve through the delivery catheter, and providing a delivery instrument having a replacement valve contained therein. The delivery instrument is advanced into the delivery catheter and intraluminally so that a distal end portion of the instrument is adjacent an annulus of a patient, and a first portion of the valve is exposed from the delivery instrument to position it on a first side of the annulus, and thereafter a second portion of the valve is exposed to position it on a second side of the annulus.

摘要： A surgical apparatus for delivering fluid to treat a lesion comprising an elongated member having a distal tip and a first and second set of openings formed in a sidewall proximal of the distal tip. The second set of openings is positioned proximally of the first set of openings. First and second set of fluid delivery members are movably positioned in the elongated for delivering fluid to the lesion. An actuator moves the fluid delivery members from a retracted position within the elongated members to a first deployed position extending radially with respect to the elongated member and moves the fluid delivery members from the first deployed position to a second deployed position extending further radially from the elongated member. The fluid delivery members are retained in the first and second deployed positions by a retention member.

摘要： A peritoneal dialysis catheter for insertion into the abdominal cavity of a patient for delivering and withdrawing fluid from a patient comprising a catheter body having a proximal portion, a distal tip portion and a first longitudinally extending lumen configured to deliver fluid into the abdominal cavity. First and second side openings are formed in an outer wall of the catheter body adjacent the distal tip portion and are in fluid communication with the first lumen and configured for passage of fluid therethrough. A stiffening insert is positioned in the distal tip portion and has a first stiffness greater than a second stiffness of the distal tip portion to facilitate entry into the abdominal cavity. The stiffening insert has a lumen therethrough communicating with the first lumen. A method for insertion of the dialysis catheter is also disclosed.

摘要： A system for treating stenosis in a target blood vessel, such as the common carotid artery, comprising a graft portion having a main portion and a branch portion extending therefrom. The branch portion extends from the intermediate portion of the main portion at an angle thereto and is in fluid communication with the main portion. A first stent is associated with the main portion and is expandable from a first configuration to a second configuration to retain the main portion in position within the target vessel. A second stent is associated with the branch portion and is expandable from a first configuration to a second configuration to retain the branch portion in position within a branching vessel. In one embodiment, the branch portion is integral with the main portion. In an alternate embodiment the branch portion is connected to the main portion.
