International Classification:

A61N 1/30

US Classification:

604019000

Abstract:

In accordance with the present invention there is provided exemplary embodiments of an introducer sheath in accordance with the present invention, wherein the introducer sheath of the present invention is formed of multiple components which are resiliently assembled to form a single introducer sheath. One embodiment of the introducer sheath includes a hub, a retaining member and an elongated tubular member. The hub has a lumen that has a groove. The elongated tubular member has a proximal end that includes a flared portion. The distal end of the retaining member is configured to be received in the groove formed in the lumen of the hub. The distal end of the retaining member contacts the flared portion of the tubular member when distal end of the retaining member is disposed in the groove such that the tubular member is retained within the lumen of the hub in a sealed engagement.

International Classification:

A61B 17/22

US Classification:

606159

Abstract:

Described here are devices and methods for performing atherectomies. Generally, the atherectomy devices may comprise a handle, a cutter assembly, and a catheter or catheter assembly therebetween. The cutter assembly may include a cutter housing and a cutter comprising a first cutting element and a second cutting element, each of which may be rotated relative to the atherectomy device to cut occlusive material.

Appl. No.:

17/611672

Inventors:

- EINDHOVEN, NL
Douglas ROWE - SAN JOSE CA, US

International Classification:

A61B 17/3207

Abstract:

An atherectomy device includes a catheter that is coupled to a handle. The catheter includes an outer sheath and a drive shaft carried within and rotatable relative to the outer sheath. A cutter assembly is coupled to and extends distally relative to the outer sheath. The cutter assembly includes a housing coupled to and extending distally from the outer sheath. A proximal cutting element is rotatably carried by the housing, and the proximal cutting element is coupled to and extends distally from the drive shaft. The proximal cutting element includes at least one proximal cutting blade, and the at least one proximal cutting blade has a negative rake angle. A distal cutting element is rotatable with the proximal cutting element relative to the housing. The distal cutting element includes at least one distal cutting blade, and the at least one distal cutting blade has a positive rake angle.

Inventors:

- SAN DIEGO CA, US
- EINDHOVEN, NL
Douglas ROWE - SAN JOSE CA, US

International Classification:

A61B 17/3207

Abstract:

An atherectomy device () for removing occlusive material from the vasculature of a subject includes a sheath () and a drive shaft () disposed within the sheath. The drive shaft () couples to a cutting element (). The drive shaft () is rotatable relative to the sheath () to rotate the cutting element (). The drive shaft () and the sheath () define therebetween a material removal passageway () for receiving the occlusive material. The drive shaft () includes a coil () having an inner lumen (). A jacket () is disposed outwardly of the coil (), and the jacket () inhibits the occlusive material in the material removal passageway () from passing through the coil and entering the inner lumen ().

Appl. No.:

17/289273

Inventors:

- EINDHOVEN, NL
Douglas ROWE - SAN JOSE CA, US
August Christopher POMBO - SACRAMENTO CA, US

International Classification:

A61B 17/3207

Abstract:

An atherectomy device includes a catheter, and the catheter includes an outer sheath. The outer sheath includes a proximal portion coupled to and extending distally relative to a handle, and the proximal portion defines a longitudinal axis of the catheter. The outer sheath also includes a distal portion coupled to and extending distally relative to the proximal portion, and the distal portion normally has a curved configuration and is offset from the longitudinal axis. The catheter further includes a drive shaft carried within and rotatable relative to the outer sheath. A cutter assembly is coupled to and extends distally relative to the distal portion of the outer sheath. A cutter is coupled to the drive shaft and rotates about a cutter rotation axis upon rotation of the drive shaft relative to the outer sheath. The cutter rotation axis is normally disposed at an acute angle relative to the longitudinal axis.
