Appl. No.:

12/938474

Inventors:

Steve Chen - Westfield IN, US
Ryan Dempsey - Westfield IN, US
Jeffrey Miller - East Haven CT, US
Amy Overby - West Lafayette IN, US

International Classification:

A61F 2/02
A61M 5/32

US Classification:

623 2372, 604272

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.

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.
