Filed:

Dec 15, 2003

Appl. No.:

10/736459

Inventors:

Jimmy Jen - Foster City CA, US
Robert George - San Jose CA, US
Jeff Dolin - Belmont CA, US
Amelia Lasser - Fremont CA, US

Assignee:

Abbott Laboratories - Abbott Park IL

International Classification:

A61B 5/00
A61M 25/00

US Classification:

600585

Abstract:

An apparatus for deploying a needle within a lumen is provided. The apparatus includes a housing having a threaded bushing radially disposed therein. The bushing rigidly couples with a nose cone having a guide tip disposed at an end opposite the bushing for penetrating an arterial wall of a lumen. During operation, a user incrementally advances the bushing within the housing, thereby incrementally advancing the guide tip into the lumen. The nose cone also includes a flex guide having a slot configuration which couples with the guide tip which deploys into the lumen along with the guide tip.

International Classification:

A61B 17/04

US Classification:

606144, 606148

Abstract:

Devices, systems, and methods for suturing of body lumens allow the suturing of vascular puncture sites located at the distal end of a percutaneous tissue tract. An elongated articulated foot near a distal end of a shaft is inserted through the penetration and actuated so that the foot extends along the lumenal axis. The foot carries suturing attachment cuffs, and needles are advanced from the shaft through the vessel wall outside of the penetration and into engagement with the needle cuffs after the foot has been drawn proximally up against the endothelial surface of the blood vessel. The cross-section of the shaft within the tissue tract can be minimized by laterally deflecting the needles as they leave the shaft, while tapered depressions within the foot can guide the advancing needles into engagement with the cuffs. The cuffs lockingly engage the needles and can be withdrawn proximally along the needle paths and through the tissue tract so as to form a loop of suture across the puncture. The articulating foot may be realigned with the shaft and withdrawn proximally through the tissue tract without dilating the tissue tract.

International Classification:

A61F 2/84

US Classification:

623 111

Abstract:

The invention is directed to a delivery system for delivering a medical device. The delivery system includes an inner member having a proximal end and a distal end. The inner member defines a longitudinal axis between the proximal end and the distal end. A tip is formed at the distal end of the inner member. A bumper is freely disposed on the inner member. The bumper has a proximal end and a distal end. A seat is defined between the tip and the distal end of the bumper. Additionally, a sheath is disposed about the inner member, the sheath having a proximal end and a distal end. The sheath is movable from a first sheath position substantially covering the seat, and a second sheath position axially offset to expose the seat. The invention also includes a handle in contact with the proximal end of the inner member.
