International Classification:

A61B 10/00

US Classification:

600567

Abstract:

An introducer cannula configured for receiving a medical instrument includes a cannula tube having a side wall surrounding a central lumen, a proximal end, and a distal end. An elongate tissue anchor is positioned in the central lumen of the cannula tube. The elongate tissue anchor has a mounting end and an anchoring free end. The elongate tissue anchor is movable in the central lumen such that the anchoring free end is movable between a retracted position and a deployed position. An actuator is coupled to the proximal end of the cannula tube. The actuator is coupled to the mounting end of the elongate tissue anchor. The actuator is operatively configured to selectively position the anchoring free end of the elongate tissue anchor in one of the retracted position and the deployed position.

600566

Abstract:

A method for using a biopsy device is disclosed. The biopsy device includes a chamber having a body having a distal end and a proximal end, wherein the proximal end includes an inlet. The biopsy device further includes a vacuum generator for generating negative and positive pressure and at least one first recessed area and at least one second recessed area. The first recessed area extends along an inner wall of the body, proximate the proximal end of the body of the chamber. The first recessed area is configured to release positive pressure within the chamber. The second recessed area extends along the inner wall of the body, proximate the distal end of the body of the chamber. The second recessed area is configured to release negative pressure within the chamber.

Inventors:

Himanshu M. Ranpura - Laveen AZ, US
Angela K. Jensen - Mesa AZ, US
Kenneth Shane Guillory - Salt Lake City UT, US

International Classification:

A61B 10/02

US Classification:

600566, 600567

Abstract:

A biopsy device includes a probe assembly and a driver unit. The probe assembly includes a first cannula having a first aperture extending to a lumen proximal to a first distal end of the first cannula. A second cannula has a second aperture extending to a lumen proximal to the second distal end of the second cannula. The second cannula is disposed co-axially with the first cannula. A least one of the first aperture and the second aperture has a cutting edge. The driver unit is configured for releasably mounting the probe assembly. The driver unit is operatively configured to simultaneously rotate the first cannula and the second cannula at different rotational velocities so that the first aperture and the second aperture periodically come into alignment to form a virtual tissue sample aperture.

International Classification:

A61B 10/02

US Classification:

600567

Abstract:

A biopsy apparatus includes a driver assembly and biopsy probe mechanism drivably coupled to the driver assembly. The biopsy probe mechanism includes a biopsy cannula having a cylindrical side wall that defines a lumen and has a side port located near a distal end that extends through the side wall to the lumen. A thumbwheel mechanism includes a thumbwheel mounted to the driver assembly to rotate about a first rotational axis, the first rotational axis being substantially perpendicular to the longitudinal axis. A first gear is mounted to the thumbwheel for coaxial rotation with the thumbwheel about the first rotational axis. A second gear is mounted to the biopsy cannula for coaxial rotation with the biopsy cannula about the longitudinal axis, the second gear being located to be drivably engaged by the first gear. The housing is grasped and the thumbwheel rotated with a single hand.

International Classification:

A61M 25/00
A61M 25/10

Abstract:

A balloon catheter for use with a guidewire includes an elongated, tubular shaft extending in a longitudinal direction, said shaft having a proximal end and a distal end. An inflatable balloon is connected to the distal end of the shaft, the balloon including a working surface. A radiopaque identifier is provided for identifying the working surface. A receiver adjacent the proximal end of the shaft is adapted for allowing the shaft to move relative to the receiver in at least the longitudinal direction.

Abstract:

A dual lumen coaxial introducer, for use with an elongate needle, includes a hub, an elongate member, and a pushrod. The elongate member has a first lumen, a second lumen, a proximal end portion, and a distal end. The proximal end portion is fixedly attached to the hub. The first lumen of the elongate member defines a longitudinal axis and is configured to slidably receive the elongate needle. The pushrod is located in the second lumen of the elongate member. The pushrod has a distal end surface. The pushrod is movable in the second lumen between a retracted position and an extended position. In the retracted position, the distal end surface of the pushrod is spaced away from the distal end of the elongate member to define a marker recess in the second lumen elongate member for carrying a tissue marker for delivery to a delivery site in a patient.
