Abstract
Abstract A device for providing access to a living body. The device, in one embodiment, includes a slotted needle dimensioned and configured to receive, in fluid tight engagement, a catheter or a guidewire introduced into the needle through the slot. The device, in another embodiment, includes a sharpened, slotted first tube, a second tube piercable by the first tube for receipt therein of at least a potion of both the first tube and the slot, and an elongated element passing into the second tube, through the slot and into the first tube. The device might further include a third tube slidably positioned around the second tube.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
259 words
A body access device comprising a first tubular element having proximal and distal ends, an outer diameter, a first outer wall, a first lumen, and a sharpened tip at said distal end; said first element having an elongated opening longitudinally disposed in said wall communicating with said first lumen and extending a predetermined distance substantially from said distal end toward said proximal end; said opening being dimensioned and configured and adapted to receive therein an elongated element; a second tubular element having proximal and distal ends, a maximum outer diameter, a second outer wall, and at least a second lumen, with said second lumen being dimensioned and configured to receive therein at least a portion of said first element; said sharpened tip being adapted to pass through said second outer wall at a location proximate said distal end thereof, with said tip being directed toward said distal end of said second element for location of at least a portion of said elongated opening within said second lumen, a substantially fluid tight seal being created at said pass through location, with said first lumen and said second lumen being in communication, wherein said elongated element may be introduced into and removed from said opening substantially non-longitudinally; and a third tubular element having proximal and distal ends, an inner diameter defining at least a third lumen, with said inner diameter of said third lumen being greater than the maximum outer diameter of said second element and with said third element being coaxially aligned with and slidably positioned around said second element.
Claim 2
Dependent Claim
259 words
A body access device comprising a first tubular element having proximal and distal ends, an outer diameter, a first outer wall, a first lumen, and a sharpened tip at said distal end; said first element having an elongated opening longitudinally disposed in said wall communicating with said first lumen and extending a predetermined distance substantially from said distal end toward said proximal end; said opening being dimensioned and configured and adapted to receive therein an elongated element; a second tubular element having proximal and distal ends, a maximum outer diameter, a second outer wall, and at least a second lumen, with said second lumen being dimensioned and configured to receive therein at least a portion of said first element; said sharpened tip being adapted to pass through said second outer wall at a location proximate said distal end thereof, with said tip being directed toward said distal end of said second element for location of at least a portion of said elongated opening within said second lumen, a substantially fluid tight seal being created at said pass through location, with said first lumen and said second lumen being in communication, wherein said elongated element may be introduced into and removed from said opening substantially non-longitudinally; and a third tubular element having proximal and distal ends, an inner diameter defining at least a third lumen, with said inner diameter of said third lumen being greater than the maximum outer diameter of said second element and with said third element being coaxially aligned with and slidably positioned around said second element.
Claim 3
Dependent Claim
283 words
A body access device comprising a first tubular element having proximal and distal ends, an outer diameter, a first outer wall, a first lumen, and a sharpened tip at said distal end; said first element having an elongated opening longitudinally disposed in said wall communicating with said first lumen and extending a predetermined distance substantially from said distal end toward said proximal end; said opening being dimensioned and configured and adapted to receive therein an elongated element; a second tubular element having proximal and distal ends, a maximum outer diameter, a second outer wall, and at least a second lumen, with said second lumen being dimensioned and configured to receive therein at least a portion of said first element; said sharpened tip being adapted to pass through said second outer wall at a location proximate said distal end thereof, with said tip being directed toward said distal end of said second element for location of at least a portion of said elongated opening within said second lumen, a substantially fluid tight seal being created at said pass through location, with said first lumen and said second lumen being in communication, wherein said elongated element may be introduced into and removed from said opening substantially non-longitudinally; and a third tubular element having proximal and distal ends, an inner diameter defining at least a third lumen, with said inner diameter of said third lumen being greater than the maximum outer diameter of said second element and with said third element being coaxially aligned with and slidably positioned around said second element, said distal end of said third element being spaced from said pass through so that said third element is not pierced by said tip.
Claim 4
Dependent Claim
283 words
A body access device comprising a first tubular element having proximal and distal ends, an outer diameter, a first outer wall, a first lumen, and a sharpened tip at said distal end; said first element having an elongated opening longitudinally disposed in said wall communicating with said first lumen and extending a predetermined distance substantially from said distal end toward said proximal end; said opening being dimensioned and configured and adapted to receive therein an elongated element; a second tubular element having proximal and distal ends, a maximum outer diameter, a second outer wall, and at least a second lumen, with said second lumen being dimensioned and configured to receive therein at least a portion of said first element; said sharpened tip being adapted to pass through said second outer wall at a location proximate said distal end thereof, with said tip being directed toward said distal end of said second element for location of at least a portion of said elongated opening within said second lumen, a substantially fluid tight seal being created at said pass through location, with said first lumen and said second lumen being in communication, wherein said elongated element may be introduced into and removed from said opening substantially non-longitudinally; and a third tubular element having proximal and distal ends, an inner diameter defining at least a third lumen, with said inner diameter of said third lumen being greater than the maximum outer diameter of said second element and with said third element being coaxially aligned with and slidably positioned around said second element, said distal end of said third element being spaced from said pass through so that said third element is not pierced by said tip.
Claim 5
Dependent Claim
