56626223, Sep 2, 1997

Filed:

Apr 4, 1995

Appl. No.:

8/409973

Inventors:

Susana M. Gore - Fort Lauderdale FL
Mark Mueller - Miramar FL
Nicholas Green - Kinnelon NJ
Jeffrey G. Gold - Parkland FL
Peter P. Soltesz - San Jose CA

Assignee:

Cordis Corporation - Miami Lakes FL

International Classification:

A61M 2500

US Classification:

604282

Abstract:

An intravascular catheter carries a helical reinforcement member embedded within at least a portion of the tubular wall of the catheter. The helical reinforcement member comprises a helical first portion having coils of greater pitch than the pitch of helical coils of a second portion. Preferably, the catheter is for insertion into brain arteries, and comprises a flexible tube having an outer diameter of no more that about 0. 05 inch, for example 3 French or smaller. The flexible tube defines outer and inner tubular layers. The inner tubular layer surrounds a catheter lumen and comprises a chemically inert fluorinated polymer such as PTFE. The outer tubular layer comprises at least three longitudinally spaced, connected tubular sections. The sections are of successively increasing flexibility from the proximal toward the distal catheter end. Also, manufacturing methods are disclosed pertaining to increasing the flexibility of a section of the catheter and joining together in abutting relation a pair of dissimilar catheter reinforcement members.

Filed:

Feb 6, 1985

Appl. No.:

6/698561

Inventors:

Jeffrey G. Gold - Miami FL
Gyan S. Pande - Miramar FL
Kevin Smith - Miami FL

Assignee:

Cordis Corporation - Miami FL

International Classification:

B29C 4706
B29C 6322

US Classification:

264139

Abstract:

A thin-walled guiding catheter of the type having a distal end adapted to be formed into curved configurations and passed through branching blood vessels and the like is prepared with a three-layered tubular body portion having a lubricious inner sheath defining a lubricious guiding lumen, a rigid intermediate sheath, and a flexible outer sheath, which may be radiopaque. The distal tip portion thereof has a similar construction, but from which the rigid intermediate sheath is omitted. The guiding catheter exhibits excellent torque response and control while being especially thin-walled, thereby permitting minimization of the outer diameter size while permitting passage of an intravascular catheter and the like through its lumen.

Appl. No.:

7/270810

Inventors:

Jeffrey G. Gold - Miami FL

Mario J. Martinez - Miami FL

Assignee:

Cordis Corporation - Miami Lakes FL

International Classification:

A61M 2500

US Classification:

604282

Abstract:

A flexible catheter comprises at least one resilient, flexible, tubular layer in telescoping relation with, and bonded to, a tubular wire sheath. A first catheter section includes the wire strands at a first angle to each other. A second catheter section includes the wire strands at a second angle to each other, with the second angle being different from the first angle so that the physical characteristics of the first and second catheter sections are different.

Inventors:

Mario J. Martinez - Miami FL

Kevin F. Hahnen - Miramar FL

Assignee:

Cordis Corporation - Miami Lakes FL

International Classification:

A61M 2500

US Classification:

604282

Abstract:

A catheter defines a flexible, tubular body in which the tubular body carries a tubular reinforcing sleeve made of strands. By this invention the catheter defines at least one side hole which communicates through the tubular body and tubular reinforcing sleeve. Greater resistance against collapse is thus provided to the section of the catheter which defines the side hole or preferably side holes.
