Abstract
Abstract A preshaped tubular catheter for percutaneous transradial approach to catheterization, comprises a distal bridge shaped portion 1 having a distal arch defining a primary curve (3), a top defining a secondary curve (5), and a proximal arch defining a tertiary curve (7). The proximal arch is connected to a straight shaft (9). The shaft (9) is stiff and the bridge shaped portion has a flexibility extending at least up to and including the primary curve (3) and a stiffeness extending at least up to and including the tertiary curve (7).

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
102 words
A preshaped tubular catheter for percutaneous transradial approach to catheterization, characterized in that it comprises a distal bridge shaped portion (1) having a distal arch (2)defining a primary curve (3), a top (4) defining a secondary curve (5), and a proximal arch (6) defining a tertiary curve (7), wherein said proximal arch (6) is connected to a distal end (8) of a straight and stiff shaft (9), and wherein said bridge shaped portion (1) has a flexibility extending at least up to and including the primary curve (3) and a stiffeness extending at least up to and including said tertiary curve (7).
Claim 2
Dependent Claim
191 words
A catheter according to claim 1, wherein the distal bridge shaped portion (1) comprises a first distal straight portion (10), a primary curve (3) extending from said first distal straight portion (10), said primary curve (3) having a concavity oriented towards a proximal end (11) of said bridge shaped portion (1), a second straight portion (12) extending from said primary curve (3), said second straight portion being inclined towards said proximal end (11) of the bridge shaped portion (1), a secondary curve (5) extending from said second straight portion (12), said secondary curve having a concavity oriented between said first distal straight portion (10) and said proximal end (11) of said bridge shaped portion (1), a third straight portion (13) extending from said secondary curve (5), said third straight portion being inclined towards the proximal end (11) of said bridge shaped portion (1), and a tertiary curve (7) extending from said third straight portion (13), said tertiary curve having a concavity oriented towards said first distal straight portion (10), and said tertiary curve having a proximal end (14) connected to said to said distal end (2) of said straight shaft (9).
Claim 3
Dependent Claim
40 words
A catheter according to claim 2, wherein said flexibility of the bridge shaped portion (1) extends at least over said first distal straight portion (10), said primary curve (3), and a distal portion (15) of said second straight portion (12).
Claim 4
Dependent Claim
15 words
A catheter according to claim 2, wherein said secondary curve (5) extends over about 90°.
Claim 5
Dependent Claim
15 words
A catheter according to claim 2, wherein said tertiary curve (7) extends over about 45°.
Claim 6
Dependent Claim
24 words
A catheter according to claim 2, wherein said second straight portion (12) and said third straight portion (13) are of essentially the same length.
Claim 7
Dependent Claim
21 words
A catheter according to claim 2, wherein said first distal straight portion (10) is substantially parallel to said straight shaft (9).
