8308658, Nov 13, 2012

Filed:

Apr 13, 2007

Appl. No.:

11/735289

Inventors:

Jason M. Albers - Buffalo MN, US
Eugene Champeau - Medina MN, US
David Liebl - Eden Prairie MN, US

Assignee:

NeoMetrics, Inc. - Plymouth MN

International Classification:

A61M 25/00
A61M 25/09

US Classification:

600585, 60416413

Abstract:

The guidewire provides a core and wire coil construction. The core can be shaped with a generally squared-off distally facing shoulder that forms a platform for a proximal end portion of the wire coil. The wire coil can have a plurality of spaced apart coil turns at its proximal end portion. A bonding agent comprising an adhesive can be used to secure the core to the wire coil proximal end portion.

International Classification:

A61M 25/09
A61C 3/00

US Classification:

600585, 433 20

Abstract:

A wire used in the medical field for guiding purposes, as well as in other fields, such as in the field of orthodontics for teeth aligning purposes. The wire, when prepared for use in such applications, exhibits an innovative blend of advantageous properties, including enhanced kink resistance over stainless steel wires and enhanced stiffness over Nitinol wires, which enhance its use as a medical guidewire or stylet, and further, as an arch wire in orthodontia applications.

Filed:

Jun 4, 1999

Appl. No.:

9/326901

Inventors:

Jeffrey A. McBroom - Champlin MN
David A. Liebl - Eden Prairie MN

Assignee:

MedAmicus, Inc. - Minneapolis MN

International Classification:

A61M 25098

US Classification:

604529

Abstract:

An introducer system has a splittable sheath which includes a marker band. The marker band allows the sheath to be viewed under fluoroscopy while inserted within a patient, and while still allowing a medical device to be introduced therethrough. In addition, the marker band allows for the sheath to be split using a slitter in a longitudinal direction which permits the sheath to be removed from the venous system without having to be withdrawn over an end of the medical device. The marker band has perforations, comprises a mesh structure, or can comprise a braid structure, which each allow for the sheath, and the marker band, to be slittable.

Appl. No.:

7/925092

Inventors:

David A. Liebl - Saint Louis Park MN
Bruce L. Funk - Maplewood MN

Assignee:

Medamicus, Inc. - Minneapolis MN

International Classification:

A61M 2900

US Classification:

604167

Abstract:

A dilator is axially movable to have its tubular member movably extended through the tubular portion of an introducer with the dilator hub abuttable against the tubular portion proximal edge. A locking finger mounted to the introducer tab (or handle) is radially extendable into a hub recess to lockingly retain the dilator and introducer in a coupled relationship to prevent accidental axial separation. The recess is formed by the hub main body and a radially extending flange to open radially outwardly. In one embodiment, the introducer tab is of a flexibility for being manually bent to move the locking finger out of the recess to permit axial separation while in a second embodiment, a flange notch is provided for the locking finger to relatively move axially therethrough when the dilator and introducer are relatively rotated from a position where the locking finger abuts against the flange. In the third embodiment, a slider is axially movable on the tab between a locking finger locked coupling position, a valving position blocking fluid flow through the tubular portion when the dilator and introducer are axially separated, and a valve open position permitting axial separation of the dilator and the introducer; while a fourth embodiment has a slider and an introducer notched flange.

Appl. No.:

7/982591

Inventors:

Gordon L. Moss - Bloomington MN
David A. Liebl - Saint Louis Park MN

Assignee:

Medamicus, Inc. - Minneapolis MN

International Classification:

A61M 2500

US Classification:

604280

Abstract:

The slitter includes a handle section having a handle member and an arcuate section joined thereto, a knife blade, a clamp member and interfitting parts for mounting the clamp member to the handle members for limited vertical movement between catheter clamping and release positions, each of the arcuate section and the clamp member having vertically opposite facing surfaces for clampingly engaging opposite surface portions of any one of a number of different outer diameter catheters. The arcuate section has a nose portion for entering between the clamped catheter and the introducer when the introducer is to be removed from the catheter without being moved over the proximal terminal end of the catheter. The knife blade is located radially outwardly of the arcuate section surface that abuts against the clamped catheter, extends radially outwardly of the nose and is located rearwardly of the forwardmost part of the nose. In one embodiment the interfitting parts are a protrusion joined to the handle member and a clamp member leg vertical slot of a greater height than the protrusion for having the protrusion extended thereinto for retaining the clamp member and the handle member in face to face abutting relationship.
