US Patent:

20070207186, Sep 6, 2007

Filed:

Mar 3, 2007

Appl. No.:

11/713361

Inventors:

John Scanlon - Wilmington DE, US
Catherine Scanlon - Wilmington DE, US

International Classification:

A61F 2/06
A61F 2/94

US Classification:

424424000, 623001490, 623001420

Abstract:

The present invention is a more durable expanded material that enables thinner wall thicknesses and a more flexible reinforcement suitable for stenting. The present invention is especially useful in the construction of grafts, stents, and stent-grafts which are used, for example, in repairing or replacing blood vessels that are narrowed or occluded by disease, aneurismal blood vessels, or other medical treatments. The inventive material and configurations allow expansion or contraction in size or adjustment in size in an incremental manner so that the optimum size, shape, and fit with other objects can be obtained. The present invention is also optionally capable of more accurately delivering one or more active ingredients such as drugs over longer periods of time. The present invention optionally includes surface modifications and additives that increase the surface adhesion of active ingredients, coatings, or combinations thereof. Finally, the present invention optionally includes growing cells on the inventive material so that the expanded material, reinforcement, or combinations thereof are useful, for example, in producing lab-grown blood vessels or organs.

Appl. No.:

15/863822

Inventors:

International Classification:

A61F 2/89
A61K 31/436
B29C 69/00

Abstract:

A multilayer bioresorbable stent having sustained drug delivery is disclosed herein. The bioresorbable stent releases a therapeutic substance from the body of the bioresorbable stent starting when the bioresorbable stent is implanted within an anatomical lumen and ending when the entire mass of the bioresorbable stent is no longer present within the anatomical lumen. The bioresorbable stent releases the therapeutic substance gradually during the treatment as the mass of the each layer of the bioresorbable stent erodes. Methods of making the therapeutic layers within the bioresorbable sent are further disclosed. Sustained drug delivery reduces the risk of late and very late stent thrombosis.

Appl. No.:

Inventors:

John James Scanlon - Wilmington DE, US
Catherine Ann Scanlon - Wilmington DE, US

International Classification:

A61L 27/58
A61F 2/95
A61F 2/82

Abstract:

Disclosed herein is a high strength, bioresorbable wall thickness suitable for use in an endoprosthesis such as a stent that is produced by first forming a wall thickness by melt processing or solution processing one or more bioresorbable materials into a tubular shape; drawing the shape from shorter length to an optimum longer length and reducing the diameter from a larger diameter to a smaller diameter to orient the molecular chains of the material; fabricating a stent from the tube formed of the oriented material by cutting a strut pattern in its wall thickness; covering the stent's struts with at least one coating to delay degradation of the bioresorbable material; covering the stent's struts with one or more controlled release active ingredients to minimize the risk of restenosis or other side effects; crimping the stent onto a balloon catheter assembly; delivering the stent into an anatomical lumen via percutaneous methods to a treatment location; radially expanding the stent from a smaller size to a larger size at the treatment location wherein the stent temporarily supports the anatomical lumen; and removing the catheter from the lumen.
