Assignee:

Medtronic, Inc. - Minneapolis MN

International Classification:

A61B 19/00

US Classification:

600 37, 600229

Abstract:

A tissue stabilizer including an elongated arm, a collet, and a head-link assembly. The collet is disposed at a distal end of the arm. The head-link assembly includes a tube and a spreading mechanism. The tube forms an intermediate section and opposing arms each terminating at a tip. The spreading mechanism can adjust a lateral distance between the tips, and includes first and second articulating members each having a leg and a collet interface body. The first member further includes a female hinge feature, whereas the second member includes a male hinge feature differing from the female hinge feature. The legs of are mounted to discrete regions of the tube, and the male hinge feature is pivotably coupled to the female hinge feature. Automatic spreading of a lateral distance between the tips occurs in response to a compressive force applied to the collet interface bodies.

International Classification:

A61B 17/22

US Classification:

606159

Abstract:

The invention provides a system and method for harvesting a vessel section. The system comprises a vessel support member, a handle, and a tubular cutting device. The vessel support member is introduced into the vessel section to be harvested. The tubular cutting device may comprise an outer tubular member or an outer and an inner tubular member. The outer tubular member carries at least one cutting element. The tubular member or members are advanced over the vessel section and vessel support member to core out the vessel section and tissue adjoining the vessel section.

International Classification:

A61M005/00

US Classification:

604/263000

Abstract:

A right angle safety needle has a base to which an arm is hingedly mounted at a proximal portion. The base has an opening at its distal portion wherethrough the vertical portion of the right angle needle extends. A well is formed adjacent the opening and a dam is provided on the side of the well away from the opening. To retract the needle from the opening, the horizontal portion of the needle, which may be encased in an arm, is rotated about the upright to which it is hingedly connected so that the needle is pivoted upwards and withdrawn from the opening. Once the tip of the needle clears the opening, due to the tip of the needle being offset from the body of the needle and the fact that the needle tends to flex forward, the tip of the needle is entrapped in the well adjacent to the opening. The dam forward of the well provides a backstop for any further forward movement of the tip of the needle, thereby fixedly retaining the needle within the well. Stops are provided in the device, at its arm and base, to prevent the needle from being further moved relative to the base once the tip of the needle is entrapped in the well of the base.

US Classification:

600374000, 606041000

Abstract:

According to the present invention, a catheter having at least one multi-purpose lumen formed through the catheter terminates proximal a relatively complex-shaped distal portion thereof. In one form of this embodiment, the relatively complex-shaped distal portion comprises a looped portion having diagnostic- and/or ablation-type electrodes coupled thereto and an elongated diameter-adjusting member coupled proximal the distal end of the looped portion. The multi-purpose lumen may be used to alternately accommodate a variety of dedicated materials; such as, (i) a guide wire for initial deployment or later repositioning of the catheter, (ii) a volume or flow of a contrast media and the like, (iii) a deployable hollow needle or tube and the like used to biopsy adjacent tissue or dispense a therapeutic agent into a volume of tissue, and (iv) a cooling fluid, such as saline solution and the like dispensed at least during therapeutic tissue ablation procedures.

Abstract:

Embodiments of the invention provide a vessel support system and a method of vessel harvesting. The system can include a cutting device, a catheter adapted to be inserted into a section of the vessel in order to support the vessel as the cutting device is advanced over the vessel, and a cannula adapted to be coupled to the vessel and adapted to receive the catheter as the catheter is inserted into the section of the vessel.

Abstract:

A surgical connection apparatus including a plurality of delivery assemblies, a housing assembly, and a drive mechanism. The delivery assemblies each include an outer member, an inner member, and optionally a retention member. The inner member is disposed within the outer member, terminates at a distal tip and forms an internal passage that is open at a window. The delivery assemblies releasably retain a self-closing clip. The housing assembly maintains the delivery assemblies in a generally circular arrangement. The drive mechanism operates to transition the delivery assembly in releasing a self-closing clip from the corresponding delivery assembly. With this construction, a plurality of self-closing clips can be simultaneously deployed in a manner effectuating, for example, an end-to-side anastomosis.
