Appl. No.:

12/313782

Inventors:

Amir Belson - Los Altos CA, US
James J. Leary - Fenton MO, US

Assignee:

Radguard, Inc. - Los Altos CA

International Classification:

H01J 35/16

US Classification:

378203

Abstract:

A radiation protection device attaches to the C-arm of a fluoroscope and shields and collimates the X-ray beam between the X-ray source and the patient and between the patient and the image intensifier. One embodiment has a radiation shield of X-ray opaque material that surrounds the C-arm of the fluoroscopy system, the X-ray source and the image intensifier. A padded slot fits around the patient's body. Another embodiment has conical or cylindrical radiation shields that extend between the X-ray source and the patient and between the patient and the image intensifier. The radiation shields have length adjustments and padded ends to fit the device to the patient. The radiation protection device may be motorized to advance and withdraw the radiation shields. A blanket-like radiation shield covers the patient in the area surrounding where the X-ray beam enters the body.

International Classification:

A61F002/06
A61B017/32

US Classification:

623/001120, 606/168000

Abstract:

Apparatus and methods for treating in-stent restenosis are described for removing stenotic material from within previously stented regions of a patient's vasculature. The apparatus includes a catheter system having a stenotic material removal mechanism mounted on a distal portion of an elongated inner catheter. A sensing means, such as one or more sensing electrodes, are positioned on an outer surface of the apparatus. In addition, the apparatus optionally includes control means for diametrically expanding the stenotic material removal mechanism for effective recanalization of the stent. A coaxial outer catheter is provided for aspirating stenotic material which is removed from within the stent. In addition, embolic filter apparatus are described for collecting the stenotic material removed from within the stent. The methods comprise operating the stenotic material removal mechanism within a body vessel, typically a coronary artery or other artery, which has become restenosed or otherwise occluded following the initial stent placement, and sensing the proximity or contact between the stenotic material removal mechanism and the stent within the arterial wall so that the stenosis can be effectively recanalized without damaging the stent. The sensing means may be used to indicate an unsafe condition that might lead to stent damage, in response to which, the stenotic material removal mechanism may be manually or automatically deactivated. Alternatively or additionally, the sensing means may be used to indicate an appropriate endpoint for the stenotic material removal process.

Assignee:

Modular Surgical, Inc. - Los Altos CA

International Classification:

A61B 17/00

US Classification:

606 1

Abstract:

Apparatus and methods are described allow the techniques of endoscopic and laparoscopic surgery to be combined into a minimally invasive hybrid surgical technique called NOTES-assisted laparoscopic surgery. Manual and robotic-controlled versions of a modular laparoscopic tool are described having a small diameter shaft that is delivered laparoscopically to a surgical site. Larger diameter working tips are delivered through a NOTES delivery tube inserted to the surgical site through a natural orifice and joined to the shaft of the modular laparoscopic tool. Larger diameter working tips improve the effectiveness of the modular laparoscopic tools and the number and size of laparoscopic ports used can also be reduced.

Appl. No.:

8/998333

James J. Leary - Sunnyvale CA

Assignee:

Prolifix Medical, Inc. - Sunnyvale CA

International Classification:

A61B17/20

US Classification:

604 22

Abstract:

Apparatus and methods are provided for recanalizing stented regions within the vasculature which have become restenosed. A shearing body is displaced within the stented region in order to dislodge the stenotic material from an interface envelope defined by the inner surface of the stent. Usually, the shearing body will be compliant and sized slightly larger than the stent in order to remove stenotic material substantially uniformly around the entire interface envelope. The shearing body may be in the form of a brush, helical row, spaced-apart disks, solid compressible body, or a variety of other specific configurations.

International Classification:

A61F 206

US Classification:

623 11

Abstract:

Apparatus and methods are provided for restoring and maintaining an open passage or lumen in a body conduit, such as a blood vessel, which has become stenosed or occluded. The apparatus includes a stent which is specially adapted for inhibiting restenosis within the stent after implantation in a body passage. In various embodiments, the apparatus also includes a catheter or other device for operating the stent to inhibit restenosis within the stented region of the body passage. The methods presented include implanting the stent within a body passage, typically a blood vessel such as a coronary artery, which has become stenosed or occluded, and operating the stent to inhibit ingrowth of stenotic material which would result in restenosis of the stented region. The stent may be operated manually to inhibit or remove ingrowth of stenotic material, for example by introducing a catheter which acts on the stent, or the stent may operate automatically to inhibit or remove ingrowth of stenotic material without manual intervention.
