Appl. No.:

10/449826

Inventors:

Sergey S. Grigoryants - Arlington MA, US
Luis J. Maseda - Cambridge MA, US

Assignee:

Boston Scientific Scimed, Inc. - Maple Grove MN

International Classification:

A61B 10/00

US Classification:

Abstract:

Transbronchial needle aspiration (TBNA) device. In one embodiment, the device comprises a handle and a flexible catheter, the handle having a bore, the proximal end of the catheter being fixed within the handle bore. A protective tubular hub having a flared distal end is press-fit coaxially within the distal end of the catheter, the distal end of the catheter being sealed around the distal end of the hub so as to define a distal opening. A hollow needle having a sharp tip at its distal end is disposed within the catheter, the needle tip being sized for insertion through the distal opening of the catheter. The distal end of a flexible wire is coupled to the proximal end of the needle, the proximal end of the wire extending through the handle bore and coupled to a button slide accessible through a slot in the handle. The button slide is movable between a distal position in which the needle tip extends through the distal opening of the catheter and a proximal position in which the needle tip is disposed within the hub. When in either its distal position or its proximal position, a pawl on the button slide releasably engages a corresponding notch on the handle to lock the button slide in place.

US Classification:

604535, 604533

Abstract:

A catheter assembly and method for internally anchoring a catheter in a patient. According to one embodiment, the catheter assembly includes a catheter, a tubular fitting coupled to one end of the catheter, and an internal bolster coaxially mounted around the tubular fitting. The tubular fitting has a waist portion, and the internal bolster is secured thereto by a snap-fit. To internally anchor the catheter in a patient, one inserts the end of the catheter to which the fitting is coupled into the patient and then, while the fitting and its coupled end of the catheter are within the patient, inserts the internal bolster over the fitting until it snap-fits into place over the waist portion, thereby internally anchoring the catheter within the patient.

Abstract:

Various embodiments of a measurement device used to measure a size of a lumen and related methods of use are disclosed. For example, the device may include a proximal handle, a distal member including a radially expandable portion, a control member connecting the proximal handle to the distal member, and a measurement indication member for displaying a value indicative of a size of the expandable portion. The radially expandable portion may be configured to expand from a contracted state to an expanded state to measure the size of a lumen.

Abstract:

In one aspect, the present invention is a system for preparing a patient for an endoscopy procedure, such as a colonoscopy. The endoscopic preparation and examination system includes an endoscope, a source of irrigation and aspiration, and a control unit. The endoscope includes an elongated flexible shaft with a distal tip and a proximal end, at least one aspiration lumen and at least one irrigation lumen. A plurality of irrigation ports are functionally connected to the at least one irrigation lumen and a plurality of aspiration ports are functionally connected to the at least one aspiration lumen. In another aspect, the invention provides a method of clearing an obstructed view in a patient prior to, or during an endoscopic examination.
