Guided Locking Balloon Protector

View page
US Patent:
5584852, Dec 17, 1996
Filed:
Apr 14, 1995
Appl. No.:
8/422095
Inventors:
Walter R. Parkola - El Cajon CA
International Classification:
A61M 2900
US Classification:
606194
Abstract:
The present invention is for a guided locking balloon protector (10) for a dilatation catheter balloon (30) which consists of a proximal cylindrical component (15) with a distal end and a proximal end and a distal cylindrical component (20) with a distal end and a proximal end. The proximal cylindrical component (15) has two longitudinally opposed raised ribs (55) defining a slot (60) and a inner diameter (40) that can slidably fit over the balloon (25). The distal cylindrical component (20) has a inner diameter (65) that can slidably fit over balloon (25) and a integral rib (75) extending proximally from the proximal end, the integral rib (75) is sized to fit in the slot (60) and is approximately the length of the proximal cylindrical component (15). Affixed to the proximal end of the integral rib (75) is a downwardly extending locking tab (80). The method of installing the guided locking balloon protector (10) over the dilatation catheter balloon (25) includes sliding the proximal cylindrical component (15) over the distal portion (35) of the catheter (30) to cover the proximal end of the balloon (25).

Multi-Layer Ink Jet Apparatus

View page
US Patent:
4392145, Jul 5, 1983
Filed:
Mar 2, 1981
Appl. No.:
6/239612
Inventors:
Walter R. Parkola - Newtown CT
Assignee:
Exxon Research and Engineering Co. - Florham Park NJ
International Classification:
G01D 1518
US Classification:
346140R
Abstract:
Multi-layer ink jet apparatus 10,110 includes a plurality of channels 12,112 comprising chambers including inlets and orifices 14,114 and transducers 22,122 coupled to the chambers 24,124. The various channels 12,112 are located in different layers 16,116 that stagger with respect to a plane transverse to the layers 16,116 so as to achieve a high density array of ink jet orifices 14,114.

Dilatation Balloon Protector With Raised Ribs

View page
US Patent:
5417707, May 23, 1995
Filed:
Oct 29, 1993
Appl. No.:
8/145895
Inventors:
Walter R. Parkola - El Cajon CA
Assignee:
Medtronic, Inc. - Minneapolis MN
International Classification:
A61M 2500
US Classification:
606194
Abstract:
A one-piece balloon protector apparatus for a dilatation catheter. The disclosed protector comprises a unitary, planar element having two sets of longitudinal ribs, one set being disposed on a first planar face of the protector along a first edge and another set being disposed on the opposite planar face of the protector on the opposite edge. The protector is installed around a dilatation catheter balloon by placing the balloon on the protector and then coiling or wrapping the protector around the balloon. The two sets of ribs thus come come into contact an interlock with one another to secure the protector in a cylindrical configuration around the balloon.

Two Piece Balloon Protector

View page
US Patent:
5569294, Oct 29, 1996
Filed:
Sep 26, 1994
Appl. No.:
8/312338
Inventors:
Walter R. Parkola - El Cajon CA
Assignee:
Medtronic, Inc. - Minneapolis MN
International Classification:
A61M 2500
US Classification:
606194
Abstract:
The present invention is for a two piece balloon protector (5) which consists of an cylindrical tube (10) and an inner elastomeric member (15). The inner elastomeric member (15) has a outer diameter that is smaller than the inner diameter of cylindrical tube (10) and fits inside of the cylindrical tube (10). The proximal end of the inner elastomeric member (15) has a return flange (30) that fits around the proximal end of cylindrical tube (10). To install the balloon protector (5) over the dilatation catheter balloon (20), cylindrical tube (10) is held fixed while the inner elastomeric member (15) is pulled longitudinally at its distal end, thus stretching the material, decreasing the longitudinal cross-section and creating a larger inner diameter in inner elastomeric member (15). The balloon protector (5) is slid over the dilatation catheter balloon (20), the longitudinal force on the inner insert (15) is released causing the inner diameter of the inner elastomeric member (15) to decrease, compressing and containing the dilatation catheter balloon (20).

Quick Assembly Catheter Manifold

US Patent:
5507732, Apr 16, 1996
Filed:
Oct 5, 1994
Appl. No.:
8/318598
Inventors:
Robert W. McClure - San Diego CA
Ernie P. Gerstmar - San Diego CA
Walter R. Parkola - El Cajon CA
Matthew S. Gibbons - San Diego CA
Everett D. Smith - Poway CA
Assignee:
Medtronic, Inc. - Minneapolis MN
International Classification:
A61M 514
A61M 2500
US Classification:
604280
Abstract:
The present invention is accomplished by providing a catheter manifold (15) having a manifold catheter lumen (115) extending longitudinally therethrough plus a rotationally symmetrical, conically tapering, elastomeric distal seal (65) for gripping the catheter shaft (70), the proximal end of the distal seal (65) having a smaller diameter than the distal end, the distal end of the manifold catheter lumen (115) being conically tapered and sized for a friction fit with the distal seal (65) when the distal seal (65) is inserted into the distal end of the manifold catheter lumen (115), the distal seal (65) having a longitudinally extending distal seal catheter lumen (120). In addition, the catheter manifold (15) has a rotationally symmetrical, conically tapering, elastomeric proximal seal (55) for gripping the guidewire shaft (135), the proximal end of the proximal seal (55) having a larger diameter than the distal end, the proximal end of the manifold catheter lumen (115) having a conical taper sized for a friction fit with the proximal seal (55 ) when the proximal seal (55) is inserted into the proximal end of the manifold catheter lumen (115), the proximal seal (55) having a longitudinally extending proximal seal catheter lumen (110). The ratio of the proximal seal (55) length to the proximal seal (55) major diameter is about 2 to 1. The ratio of the distal seal (65) length to the distal seal (65) major diameter is about 2 to 1.
