Graduated sheath and dilator assembly
First Claim
1. A sheath and a dilator assembly comprising:
- a sheath having a proximal sheath end, a distal sheath end, and a generally tubular sheath body extending between the proximal sheath end and the distal sheath end, wherein the sheath body includes sheath indicator indicia extending from the distal sheath end toward the proximal sheath end; and
a dilator disposed within the sheath, wherein the dilator includes a proximal dilator end extending proximally of the proximal sheath end, a distal dilator end extending distally of the distal sheath end, and a dilator body extending between the proximal dilator end and the distal dilator end, wherein the dilator body includes dilator indicator indicia extending from the distal dilator end toward the proximal dilator end, such that the sheath indicator indicia and the dilator indicator indicia display predetermined dimensions from the distal dilator end toward the proximal dilator end.

Abstract
A sheath and a dilator assembly is disclosed. The assembly includes a sheath having a proximal sheath end, a distal sheath end, and a generally tubular sheath body extending between the proximal sheath end and the distal sheath end. The sheath body includes sheath indicator indicia extending from the distal sheath end toward the proximal sheath end. A dilator is disposed within the sheath. The dilator includes a proximal dilator end extending proximally of the proximal sheath end, a distal dilator end extending distally of the distal sheath end, and a dilator body extending between the proximal dilator end and the distal dilator end. The dilator body includes dilator indicator indicia extending from the distal dilator end toward the proximal dilator end, such that the sheath indicator indicia and the dilator indicator indicia display predetermined dimensions from the distal dilator end toward the proximal dilator end.

7. A sheath and dilator assembly comprising:
-
a sheath having;
a proximal sheath end;
a distal sheath end;
a generally tubular sheath body extending between the proximal sheath end and the distal sheath end, wherein the sheath body includes sheath indicator indicia extending from the distal sheath end toward the proximal sheath end; and
a first connecting means disposed at the proximal sheath end; and
a dilator disposed within the tubular sheath body, wherein the dilator includes;
a proximal dilator end extending proximally of the proximal sheath end;
a distal dilator end extending distally of the distal sheath end;
a dilator body extending between the proximal dilator end and the distal dilator end, wherein the dilator body includes dilator indicator indicia extending from the distal dilator end toward the proximal dilator end, such that the sheath indicator indicia and the dilator indicator indicia display predetermined dimensions from the distal dilator end toward the proximal sheath end; and
a second connecting means disposed at the proximal dilator end, wherein the first and second connecting means are releasably engageable with each other to releasably secure the dilator within the sheath. - View Dependent Claims (8, 9, 10, 11)

13. A method of inserting a sheath and dilator assembly into a patient'"'"'s blood vessel, wherein the sheath and dilator assembly comprise:
-
a sheath having a proximal sheath end, a distal sheath end, and a generally tubular sheath body extending between the proximal sheath end and the distal sheath end, wherein the sheath body includes sheath indicator indicia extending from the distal sheath end toward the proximal sheath end; and
a dilator disposed within the sheath, wherein the dilator includes a proximal dilator end extending proximally of the proximal sheath end, a distal dilator end extending distally of the distal sheath end, and a dilator body extending between the proximal dilator end and the distal dilator end, wherein the dilator body includes dilator indicator indicia extending from the distal dilator end toward the proximal dilator end, such that the sheath indicator indicia and the dilator indicator indicia display predetermined dimensions from the distal dilator end toward the proximal dilator end;
wherein the method coi nprises inserting the distal dilator end and the distal sheath end into the blood vessel a distance determined by the sheath indicator indicia and the dilator indicator indicia. - View Dependent Claims (14, 15)
