Integral cerebro-vascular access system
First Claim
1. A system for obtaining access to a blood vessel comprising:
- a flexible guide wire for guiding the system to a blood vessel;
a tubular member having an outer surface, an inner surface, and a lumen configured and dimensioned to slidingly receive the guide wire therein;
an introducer having a lumen configured and dimensioned to slidingly receive the tubular member therein and a distal section including a S-shaped curve for assisting in positioning the system in the blood vessel; and
a sheath having a lumen configured and dimensioned to slidingly receive the introducer therein, wherein the S-shaped curve of the distal section of the introducer positions the system in a desired position in a mouth of the blood vessel, the tubular member is configured and positioned to extend past through the introducer and into the blood vessel, and the guide wire, tubular member, and introducer can be removed to allow the sheath to thereafter provide access to the blood vessel after the system has been advanced to the desired position in the blood vessel.

Abstract
A system and method for percutaneous access to a blood vessel is disclosed. The system according to the present invention includes a flexible guide wire for guiding the system to a desired position in a blood vessel; a tubular member having a lumen sized to slidingly receive the guide wire; an introducer having a lumen sized to slidingly receive the tubular member and a distal section including a S-shaped curve for assisting in positioning the system in the blood vessel; and a sheath having a lumen sized to slidingly receive the introducer, wherein the sheath provides access to the blood vessel after the system has been advanced to the desired position in the blood vessel.

12. A system for obtaining access to a blood vessel comprising:
-
a flexible guide wire for guiding the system to a blood vessel; a tubular member having an outer surface, an inner surface, and a lumen configured and dimensioned to slidingly receive the guide wire therein; an introducer having a lumen configured and dimensioned to slidingly receive the tubular member therein and a distal section including a S-shaped curve for assisting in positioning the system in the blood vessel; and a sheath having a lumen configured and dimensioned to slidingly receive the introducer therein, wherein the S-shaped curve of the distal section of the introducer comprises a first curved segment extending in a first direction and having a flexible tip for facilitating deflection into a mouth of the blood vessel and a second curved segment extending in a second direction different from the first direction, with the second curved segment being approximately three times as long as the first curved segment and wherein the S-shaped curve of the distal section of the introducer positions the system in the desired position in the mouth of the blood vessel, and the guide wire and tubular member can be removed to allow the sheath to thereafter provide access to the blood vessel after the system has been advanced to the desired position in the blood vessel. - View Dependent Claims (13, 14)
