Appl. No.:

11/963577

Inventors:

Steve Kaipin Chen - Carmel IN, US

Assignee:

Wilson-Cook Medical Inc. - Winston-Salem NC

International Classification:

A61M 29/00

US Classification:

606191, 623 2365

Abstract:

An intragastric member and method of delivery thereof are described. Delivery of the intragastric member is enabled by partitioning the intragastric member into discrete bundles with retaining members that are circumferentially disposed along the longitudinal length of the intragastric member. Formation of the intragastric member into bundles facilitates controlled delivery into the gastric lumen. The use of suture ties enables deployment of the intragastric member into the gastric lumen. The distal ends of the suture ties are affixed to the bundles. Pulling on the proximal free end of each of the suture ties enables the corresponding bundles to be advanced distally along a delivery tube. The suture ties are pulled until each of the bundles slide off from the delivery tube and enter into the gastric lumen.

Abstract:

This invention provides, in certain aspects, unique devices and methods for treating fistulae. In one embodiment, an inventive device includes an elongate graft body having a proximal end and a distal end. The graft body is configurable to a first condition and a second condition, the second condition including the distal end deflected laterally relative to its position in the first condition of the body. The device also includes a tether, which is connected to the graft body, and is configured to traverse proximally along the body. The tether is manipulable to convert the graft body from the first condition to the second condition. Such a device may also include one or more additional tethers connected to the graft body. For instance, a second tether can be configured to extend distally from the distal end of the graft body, and may be effective in pulling the graft body along a fistula tract.

International Classification:

A61B 17/08

US Classification:

606151000

Abstract:

A clip device for hemostasis includes a clip having a proximal end portion and at least two arm portions extending from the proximal end portion and provided with a tendency to open. A sliding ring is provided for closing the arm portions of the clip. A first retainer is attached to the clip, and the first retainer is configured to be releasably secured to a second retainer that may be attached to an operating wire or a torque cable. In operation, the clip device is advanced to a target site in a body cavity. An outer sheath is retracted to expose the clip, causing the arms to open. An inner sheath is advanced distally, causing the sliding ring to advance distally to close the arms of the clip. Stop elements may be disposed on the clip to ensure that he sliding ring is not advanced distally over the clip. Then, the first retainer is disengaged from the second retainer. Various mechanisms are disclosed to permit the first and second retainers to disengage from one another. The first retainer, attached to the clip, is left inside the patient's body cavity, while the second retainer is removed from the patient.

International Classification:

A61M 29/00

US Classification:

606191000

Abstract:

Described are medical graft products, systems, and methods useful for treating fistulae, particularly enterocutaneous fistulae. Certain products of the invention are configured to have portions residing in and around a primary fistula opening in a wall of the alimentary canal. One such product includes a biocompatible graft body which is configured to block at least the primary opening. The graft body includes a capping member connected to an elongate plug member. The capping member is configured to contact portions of the alimentary canal wall adjacent to the primary opening, and the elongate plug member is configured to extend into at least a portion of the fistula. A graft product of this sort may be particularly adapted to allow a portion of the capping member to be positioned alongside an exterior, lateral surface of the plug member, e.g., when placed in a delivery device lumen. Such a capping member may be hingedly or non-hingedly coupled to the elongate plug member.

US Classification:

424423, 604500

Abstract:

Tissue augmentation devices, as well as methods of manufacturing and using the same, are disclosed. In certain embodiments, a tissue augmentation device comprises an elongate tissue penetrating member and an amount of remodelable material, wherein at least a portion of the elongate member is cannulated, and at least a portion of the amount of material is received within at least a portion of the cannulated portion of the elongate member. The elongate tissue penetrating member may provide at least one deformation that is configured to constrict portions of the amount of remodelable material received within the elongate member. In alternate embodiments, a flexible covering over an implantable biomaterial provides protection and allows an easier delivery of the biomaterial to a tissue tract.

Abstract:

Described, in certain inventive embodiments, are unique devices and methods for introducing implants into soft tissue of a patient. One of these devices includes a tissue-penetrating member that is configured to pass in its entirety through a volume of patient tissue. The tissue-penetrating member has a leading end and a trailing end, and provides a receiving space for receipt of an implant body portion for carrying the implant body portion into the volume of patient tissue. The device also includes an implant that has an implant body portion removably received in the receiving space of the tissue-penetrating member. The implant body portion is configured for deployment from the receiving space in the volume of patient tissue so as to remain deployed there along a passageway traversed by the tissue-penetrating member.
