摘要： An intravascular catheter such as a dilatation catheter for angioplasty procedures having a removable distal shaft section. The catheter construction allows the original distal shaft section of the catheter to be removed and a replacement distal shaft section to be secured to the proximal section which is useful with angioplasty catheters when the dimensions of the balloon on the original distal shaft section are inappropriate for dilating a particular stenotic region. Such catheter construction is also useful when there is a need to implant a stent into a dilated stenotic region to maintain its patency.

摘要： A device and method of using the device for contraception or sterilization and particularly for reversible contraception by occluding a reproductive lumen to prevent the passage of reproductive cells through the lumen for a desired period of time until the patient wishes to become fertile again and then be reopened. The occluding member preferably comprises a tubular framework formed from a shape memory material configured to be implanted in a reproductive lumen. The occluding member is implanted within a body lumen, secured to the wall of the reproductive lumen and then collapsed to collapse the wall and occlude the lumen. Alternatively, the occluding member may be collapsed upon a solid plug. The closure of the reproductive lumen may be reversed by introducing a balloon catheter and by a series of inflations of the balloon reexpanding the collapsed occluding member or by removing the plug. The occluding member and the plug may be configured to facilitate endothelialization, to provoke an inflammatory responses or to deliver a drug.

摘要： A balloon catheter has a combined balloon inflation and guide wire lumen. A guide wire tube in a distal port of the lumen inhibits loss of inflation medium through the port even when the balloon is inflated at relatively high pressures. The guide wire tube provides sufficient clearance with the guide wire, however, so that the catheter may be axially translated over the guide wire without excessive friction.

摘要： A balloon catheter comprises a catheter body having an elastomeric balloon at its distal end. The balloon has a small diameter vent hole disposed near its distal end. The balloon catheter may be prepared by flushing an inflation lumen and the interior of the balloon with a suitable liquid flushing medium, where the balloon is inflated by the flushing medium beginning at its proximal end and moving toward its distal end.

摘要： A pressure monitoring guidewire and method of using the same for a coronary procedure such as angioplasty, angiography, or valvuloplasty. The guidewire has a main tubular member and a more flexible tubular extension with one or more pressure monitoring ports on the distal end thereof. The distal end portion of the guidewire is advanced beyond the distal end of the dilatation catheter, with the pressure monitoring port in a portion of the coronary anatomy where pressure is to be monitored. With the guidewire so positioned, the pressure in the desired portion of the coronary anatomy is measured at the proximal end of the guidewire through the proximal opening in the main tubular member.

摘要： The ventricular drainage system includes an antisiphon device comprising a flow through body which has an interior chamber and which is adapted to be positioned for vertical flow therethrough. The device further includes an inflow tract at the lower end of the body, adapted to be coupled to a ventricular catheter, and an outflow tract at the upper end of said body adapted to be coupled to a drainage tubing. The device also includes a ball in the chamber which is capable of closing the inflow tract when there is no flow of fluid from the ventricular catheter, capable of allowing fluid flow through the body during normal flow of liquid from the catheter and capable of closing the outflow tract upon a rush of fluid from the catheter.
