US Patent:

20130282036, Oct 24, 2013

Filed:

Apr 23, 2013

Appl. No.:

13/868492

Inventors:

Jeremy R. Schaeffer - Bloomington IN, US

Assignee:

COOK MEDICAL TECHNOLOGIES LLC - Bloomington IN

International Classification:

A61B 17/34

US Classification:

606159

Abstract:

A wireguide set is provided for changing access between two access sites. The wireguide set includes a wireguide and a catheter. The wireguide passes through one access site while the catheter passes through another access site. The wireguide and catheter are connectable to each other inside the patient's body. Once connected, the catheter can pull the wireguide through the access site of the catheter. The wireguide set may be used to treat peripheral arterial disease occlusions in the lower leg where it is difficult or impossible to gain access through the occlusion from a femoral site.

Appl. No.:

13/548618

Inventors:

Jeremy R. Schaeffer - Bloomington IN, US

International Classification:

A61B 10/02

US Classification:

600567

Abstract:

Disclosed is biopsy device that includes a stylet with a sample cavity at the end, a cutting cannula movable over the stylet with a cutting end, a firing mechanism operable to suddenly change the position of the cutting cannula to move the cutting cannula over the sample cavity and a grip from which the stylet and cutting cannula extend, where the grip is held in the palm of one hand with the web of the hand between the index finger and the thumb with the stylet and the cutting cannula oriented along the longitudinal axis of the grip and a trigger on the end of the grip to actuate the firing mechanism, where the trigger is operated by the thumb of the hand gripping the grip to actuate the firing mechanism while the same hand holds the grip in a palm grip.

A61M 25/01

Abstract:

A lumen re-entry system includes a catheter having an elongate tubular body defining a wire lumen extending from an open proximal end of the elongate tubular body to a distal opening through the elongate tubular body. An abrasion resistant tubular liner is positioned within the wire lumen and has a fixed position relative to the elongate tubular body. The abrasion resistant tubular liner defines a reduced wire lumen extending from an open proximal end of the abrasion resistant tubular liner to an open distal end of the abrasion resistant tubular liner. A puncture wire is configured for axial movement through the reduced wire lumen and has an angled distal segment terminating in a puncture tip. The angled distal segment is oriented at an angle between about 10 degrees to about 90 degrees relative to a central longitudinal axis of the puncture wire.

International Classification:

A61B 17/12

US Classification:

606200

Abstract:

A detachable treatment device delivery system includes a delivery sheath defining a lumen, a treatment device having a proximal attachment segment, which includes an enlarged outer diameter region, configured for receipt within the delivery sheath, and a deployment wire configured for receipt within the delivery sheath. A delivery configuration is defined by an overlap of a distal segment of the deployment wire and the enlarged outer diameter region within an attachment zone of the delivery sheath. The deployment wire and the treatment device have a combined outer diameter at the overlap, and, in the delivery configuration, the overlap is proximally spaced from a narrowed diameter region of the attachment zone, which has a smaller diameter than the combined outer diameter. In a deployed configuration, the deployment wire is proximally spaced from the attachment zone, and the proximal attachment segment is permitted to advance through the distal opening.

Abstract:

A detachable treatment device delivery system includes a delivery sheath defining a lumen, a treatment device having a proximal attachment segment configured for receipt within the delivery sheath, and a deployment wire configured for receipt within the delivery sheath. A delivery configuration is defined by an overlap of a distal segment of the deployment wire and the proximal attachment segment within an attachment zone of the delivery sheath. In the delivery configuration, an inner surface of the delivery sheath is outwardly expanded and compressed around the deployment wire and the treatment device at the overlap. In a deployed configuration, the deployment wire is proximally spaced from the attachment zone, and the proximal attachment segment is distally spaced from the attachment zone and the distal opening.

Abstract:

An occlusion system includes a delivery catheter having an elongate body defining a delivery lumen, and an occlusion device including a bundle of elongate occlusion wires configured for simultaneous delivery through the delivery lumen. At least a portion of each of the occlusion wires includes a shape memory material and has a preformed shape. The occlusion system includes a delivery configuration in which each of the occlusion wires is positioned within the delivery lumen, urged against the preformed shape, and substantially parallel to a longitudinal axis of the delivery lumen, and a post-deployment configuration in which each of the occlusion wires is released from the delivery lumen and conforms to the preformed shape. According to the preformed shape, each of the occlusion wires has a longitudinal segment remaining parallel to the longitudinal axis and a curved end providing an outward radial force with respect to the longitudinal axis.

US Classification:

604500, 604 9301

Abstract:

A delivery device assembly for delivering a medical device to a target site within a patient includes a first polarizable tine and a second reactive tine that is not polarized. The first tine is connected to a first wire that has an electric coil surrounding a portion of the first wire. A current is passed through the electric wire to cause the polarizable tine to become polarized, thereby causing the reactive tine that is not coupled to the electric coil to move toward the polarized tine. The relative movement of the tines releases the medical device from its attachment to the tines.
