Appl. No.:

10/754282

Ronald Jones - Racine WI, US
John Baker - Racine WI, US
Patrick McCarthy - Franklin WI, US
Jon Lindquist - Kenosha WI, US

International Classification:

B23P011/00
B21D039/00

US Classification:

029506000, 029505000, 029509000

Abstract:

This invention is directed to a method for joining, by axial movement, inner and outer metal pieces having different hardnesses. The method involves forming the harder piece to have a radial groove in its juncture surface. The harder piece has leading and trailing portions on either side of the radial groove. The leading portion is dimensioned to permit it to slide with respect to the softer piece and the trailing portion is dimensioned for swaging interference with the softer piece. Relative male-female axial movement is imparted to the pieces, thereby urging the junction surface of the softer piece along the leading portion of the harder piece until the softer piece engages the trailing portion of the harder piece. Relative axial force is applied for continued axial movement whereby the softer piece is forced past the groove such that swaging interference causes a portion of the softer piece to be upset into the groove, thereby creating a permanent joint between the pieces.

Patrick M. McCarthy - Evanston IL, US

Assignee:

Northwestern University - Evanston IL

International Classification:

A61F 2/24

Abstract:

An annuloplasty ring including elastic features that make the ring optimal for receiving a subsequent prosthetic valve via a “Valve In Ring Procedure.” The elastic features provide a squeezing force on the native valve annulus that both ensures coaptation of the native valve leaflets and also prevents paravalvular leakage around a subsequently-placed prosthetic valve.

Inventors:

- Evanston IL, US
Patrick M. McCarthy - Evanston IL, US

Assignee:

Northwestern University - Evanston IL

International Classification:

A61F 2/24
A61B 90/00

Abstract:

A ring sizer including a face plate that has markings usable to provide measurements of a valve. The sizer may include a clear face plate on which the markings are provided such that the valve is visible through the face plate facilitating accurate measurements of various valve dimensions and optimal ring sizing.

Appl. No.:

16/900781

Inventors:

- Evaston IL, US
Patrick M. McCarthy - Winnetka IL, US

Assignee:

NORTHWESTERN UNIVERSITY - Evaston IL

International Classification:

A61F 2/24

Abstract:

An annuloplasty device that includes at least one helical coil usable for percutaneous implantation and activatable such that a length of the coil shortens, thereby reducing a circumference of a dilated valve annulus.

International Classification:

A61K 9/70

Abstract:

The present invention provides single sheet and compound para-xylene films for therapeutic uses. For example, the present invention provides single sheet para-xylene films useful as tissue separators and/or adhesion barriers in a subject, where the top and/or bottom surfaces of such films have a water contact angle between 75 and 95 degrees (e.g., to prevent adhesion formation). The present invention also provides compound films composed of at least two para-xylene polymer films with a therapeutic molecule layer in between. Such compound films, when used in vivo (e.g., as a tissue separator and to treat inflammation or atrial fibrillation) allow either therapeutic molecule elution through one of the para-xylene layers, or therapeutic molecule release when the compound film is pierced, such as when it is sutured in place.
