Abstract:

The present invention is accomplished by providing a catheter manifold (15) having a manifold catheter lumen (115) extending longitudinally therethrough plus a rotationally symmetrical, conically tapering, elastomeric distal seal (65) for gripping the catheter shaft (70), the proximal end of the distal seal (65) having a smaller diameter than the distal end, the distal end of the manifold catheter lumen (115) being conically tapered and sized for a friction fit with the distal seal (65) when the distal seal (65) is inserted into the distal end of the manifold catheter lumen (115), the distal seal (65) having a longitudinally extending distal seal catheter lumen (120). In addition, the catheter manifold (15) has a rotationally symmetrical, conically tapering, elastomeric proximal seal (55) for gripping the guidewire shaft (135), the proximal end of the proximal seal (55) having a larger diameter than the distal end, the proximal end of the manifold catheter lumen (115) having a conical taper sized for a friction fit with the proximal seal (55 ) when the proximal seal (55) is inserted into the proximal end of the manifold catheter lumen (115), the proximal seal (55) having a longitudinally extending proximal seal catheter lumen (110). The ratio of the proximal seal (55) length to the proximal seal (55) major diameter is about 2 to 1. The ratio of the distal seal (65) length to the distal seal (65) major diameter is about 2 to 1.
