An artificial hip joint stem is used to replace the damaged femoral head or acetabulum and includes a stem body having a head fixing part, which fixes a head, and an operating space horizontally opened at the upper side thereof. A head insertion hole connects to the operating space. A screw part is inserted into the head insertion hole. An operation converting part is inserted into the operating space to vertically move by the screw part when the operation converting part is connected to the screw part. A fixing bracket is inserted into the operating space such that the screw part is fixed to rotate without changing the depth thereof. A variable operating part is inserted into a supporting surface of the stem body to adjust a horizontal width by means of the operation converting part. A movable pin fixes the variable operating part to the operation converting part.

A modular acetabular cup assembly for use with multiple bearing liners is disclosed. The acetabular cup assembly includes a shell having a tapered inner wall and two circumferential grooves. The shell may be used with polyethylene, ceramic, metal, and other types of liners.

A visceral double-barreled main body stent graft and methods for its use, the stent graft comprises, a main body stent graft having distal and proximal ends, the main body stent graft's length ranges from about 100-120 mm and diameter at the proximal end ranges from about 30-45 mm, first and second lumens defined at the main body stent graft's distal end, the first lumen's diameter ranges from about 18-20 mm, the second lumen's diameter ranges from about 16-18 mm, the first and second lumens have about the same length from about 50-70 mm, the first lumen is secured to the second lumen along a shared length, and the main body stent graft defines a tubular wall that is contiguous with the first and second lumens such that any fluid entering the main body must exit through one of the first or second lumens.

Apparatus is provided for use with a delivery catheter, including a primary stent-graft and a flared endovascular stent-graft, which is configured to initially be positioned in the delivery catheter in a radially-compressed state, and to assume a radially-expanded state upon being deployed from the delivery catheter. The primary stent-graft includes: a structural member, which includes a plurality of structural stent elements, and which, when the flared endovascular stent-graft assumes the radially-expanded state, is shaped so as to define a flared caudal portion, which flares radially outward in a caudal direction; at least one biologically-compatible substantially fluid-impervious flexible sheet, which is coupled to at least the flared caudal portion; and a stent-engagement member, which is generally tubular when the flared endovascular stent-graft assumes the radially-expanded state, which is disposed at least partially within the flared caudal portion, and which is configured to be sealingly coupled to the primary stent-graft.

In some embodiments, an apparatus includes a catheter assembly and a handle assembly that can be removably coupled to the catheter assembly. A valve holding tube defines a lumen configured to receive a prosthetic mitral valve in a compressed configuration and can be removably coupled to a distal end portion of the handle assembly. The valve holding tube can be received within a hub of the catheter assembly when coupled to the handle assembly. The actuator when actuated is configured to cause the tensioning unit to travel along a traveler strap of the catheter assembly moving the handle assembly distally such that a distal end of an elongate shaft of the handle assembly moves the prosthetic mitral valve distally out of the valve holding tube and out a distal end of the sheath such that the prosthetic mitral valve is free to move to a biased expanded configuration.

The present disclosure relates to a delivery catheter and the stepwise release of a stent from the catheter into the vasculature of a patient, as well as a loading device for a transcatheter heart valve (THV) prosthesis.

A delivery system for delivering a prosthesis includes a catheter and a selectable tip kit having a plurality of tips. Each tip is uniquely shaped, i.e., has a particular shape different than the shape of all the other tips, and each tip is better suited for some procedures than for others. One of the tips is selected by the physician as being particularly well suited for the procedure to be performed. The selected tip is non-removably attached to the catheter and the remaining tips are discarded. This allows the delivery system to be customizable to each procedure, putting the physician in control of the case. This provides a case specific delivery system for the physicians to use and at a very low expense and with minimal additional engineering.

A method for removing fluid from a patient is provided, the method including: deploying a ureteral stent or ureteral catheter into a ureter of a patient to maintain patency of fluid flow between a kidney and a bladder of the patient; deploying a bladder catheter into the bladder of the patient, wherein the bladder catheter comprises a distal end configured to be positioned in a patient's bladder, a drainage lumen portion having a proximal end, and a sidewall extending therebetween; and applying negative pressure to the proximal end of the bladder catheter to induce negative pressure in a portion of the urinary tract of the patient to remove fluid from the patient. Systems and kits related thereto also are provided.
