An enhanced geometry receiving element for a downhole tool, such as an enhanced geometry receiving element for a plunger downhole tool used in the oil and gas industry. In one embodiment, the enhanced geometry receiving element includes a set of axial grooves disposed in the interior of a fishing neck portion of a bypass plunger.

Enhanced geometry receiving element for a downhole tool

Embodiments of this technology may include an apparatus for drying tissue. The apparatus may include human donor tissue placed in contact with and between at least two layers of backing material. This tissue and backing layer may then be restrained by two plates. This tissue may be amniotic tissue. The backing layer may include woven or nonwoven material. This backing layer may be wetted with a saline solution. At least one of the plates of the tissue drying apparatus may be perforated. The tissue assembly along with the plates may then be placed inside a chamber configured to receive the plates and tissue assembly. The chamber may be configured so that gas can be forced into the chamber with the gas flow going around the plates and the tissue assembly.

Systems for drying sheets of donor-provided human tissue

Embodiments of the present technology may permit for native, intact, natural, human-derived, or allograft-derived fibers to be used as threads for suturing. Embodiments may include a thread for suturing. The thread may include a first portion, which includes a fascia fiber. The first portion may have a first end that includes the fascia fiber. The thread may also include a second portion including a non-human-derived fiber. The second portion may have a first end that includes the non-human-derived fiber. The first end of the second portion may be attached to the first end of the first portion. Embodiments may include a method of forming a thread. The method may include attaching a first end of a fascia fiber to a first end of a first non-human-derived fiber. The method may also include attaching a second end of the fascia fiber to a first end of a second non-human-derived fiber.

Fascia fibrous compositions and methods for their use and manufacture

Embodiments of the present technology include a method of making a bone composite graft for administration to a patient. The method may include combining a human cadaveric bone material with a plurality of polymethyl methacrylate binder particles and spincasting the combined human cadaveric bone material and polymethyl methacrylate binder particles to produce the bone composite graft. The method may also include ablating the bone composite graft to increase the surface area of bone material exposed. The human cadaveric bone material may be immobilized in the plurality of polymethyl methacrylate binder particles. The human cadaveric bone material may be present in an amount that is 50 weight percent of the bone composite graft, or less. Additionally, the bone composite graft may have a yield strength that is at least 13,000 N/cm2 and no greater than 15,000 N/cm2.

Composite bone constructs and methods

Composite grafts including a biocompatible, synthetic scaffold; and a biological tissue component obtained or derived from a deceased donor tissue, wherein the biological tissue component is embedded in the biocompatible, synthetic scaffold, are provided as systems relating thereto. Methods of manufacture and methods of treatment using such grafts are also provided.

Composite grafts, systems, and methods

Embodiments of the technology may involve a method of processing the human donor tissue for administration to a recipient. This method may include the step of contacting the human donor tissue with a backing layer, where the human donor tissue and the backing layer contain a saline solution. This saline solution may include a solvent and a disassociated salt. The method may further include evaporating a portion of the solvent from a surface of the backing layer. The evaporation of the solvent may move a portion of the disassociated salt from the donor tissue to the backing layer. This process may then result in a tissue that is mostly dry and free of salt crystals.

Methods of drying sheets of donor-provided human birth tissue

Embodiments of the present technology include a graft for administration at a treatment site of a patient. The graft may include a human cadaveric bone material bonded together with a polymeric binder. The human cadaveric bone material may include demineralized bone particles. The demineralized bone particles may have an average diameter less than 1.1 mm, less than 750 &#x3bc;m, less than 500 &#x3bc;m, or less than 250 &#x3bc;m. The human cadaveric bone material may include non-demineralized bone, cancellous bone, and/or cortical bone in embodiments. In some embodiments, bone from animals other than humans may be used, and the patient may be an animal other than a human.

Embodiments of the present invention encompass fascia, fat, and dermis fibrous compositions, and methods for their manufacture and use. In a first aspect, embodiments of the present invention encompass methods for obtaining a fascia fiber for use in producing a biotextile. Exemplary methods may include treating a cadaveric fascia tissue with acetone, and obtaining the fascia fibers from the treated fascia tissue. In some cases, methods may include processing the fascia fibers to produce the fibrous fascia biotextile.

Embodiments of the present invention encompass graft assemblies, and methods for their use and manufacture. An exemplary bone graft assembly includes first and second bone pieces having respective mating features which, when combined, define non-uniform press fit. Related embodiments encompass graft assemblies having enclosed or hidden mating features.
