Abstract:
A needle access assembly and method for obtaining percutaneous needle access with little or no fluoroscopy. The method can include selecting a target for percutaneous access, directing a laser guide at a desired needle-insertion angle and in line with the selected target, aligning the needle access assembly with the laser, and inserting the needle into the target.

Abstract:
A chitosan material is treated in a nitrogen field by applying energy to ionize nitrogen in and around the chitosan, and the chitosan material is formulated into a hydrogel which can be utilized as a drug delivery vehicle for medicaments or therapeutic agents to treat certain conditions, such as cancers.
Abstract:
A powder chitosan-based material can be used for biomedical applications. The chitosan has been treated in a nitrogen field by applying energy to ionize nitrogen in and around the chitosan material. A single or multiple such treatments may be employed. For example, the chitosan material may be irradiated under nitrogen using γ-irradiation, treated under a nitrogen plasma, or both. A powder chitosan material can be readily treated by surface modifying treatments such as irradiating under nitrogen using γ- irradiation, treating under a nitrogen plasma, or both.
Abstract:
A thin chitosan-based material can be used for biomedical applications. The chitosan has been treated in a nitrogen field by applying energy to ionize nitrogen in and around the chitosan material. A single or multiple such treatments may be employed. For example, the chitosan material may be irradiated under nitrogen using γ-irradiation, treated under a nitrogen plasma, or both. A thin chitosan material can be readily treated by surface modifying treatments such as irradiating under nitrogen using γ-irradiation, treating under a nitrogen plasma, or both. A treated thin chitosan material can be utilized to control bleeding and assist in treatment and healing during a surgical procedure, including laparoscopic partial nephrectomy.

Abstract:
A treatment for reducing brain or other injury that can be used before, during, or after a surgical treatment or other injury to the brain to decrease or prevent subsequent damage. Injury to the brain during surgery or from other trauma can create elevations in brain edema and blood-brain barrier disruption thereby decreasing neurological recovery and patient outcomes. Treatment of the brain with venom, including snake venom, prior to or after injury can reduce the bleeding, swelling, and/or inflammation that results from the trauma. These pre-conditioning and/or rapid-conditioning treatments of the brain with venom can reduce brain edema and blood-brain barrier disruption and improve patient outcomes.
