Compositions and methods for promoting hemostasis and other physiological activities

Compositions that include nanoscale structured materials or precursors thereof (e.g., self-assembling peptides) are described. The compositions can include other substances (e.g., a vasoconstrictor). Also described are methods for using the compositions to promote hemostasis, to protect the skin or wounds from contamination, to decontaminate a site upon removal of previously applied compositions that provided a protective coating, and to inhibit the movement of bodily substances other than blood. The compositions are also useful in isolating tissue, removing tissue, preserving tissue (for, e.g., subsequent transplantation or reattachment), and as bulking, stabilizing or hydrating agents. Medical devices that include the compositions (e.g., a stent or catheter), bandages or other wound dressings, sutures, and kits that include the compositions are also described.

Hemostatic sponge and article

A hemostatic article, e.g., a sponge is pretreated with predetermined quantities of selected hemostatic agents to assist hemostasis in surgical or traumatic wounds. The hemostatic article is provided with a visible marking / indication of the strength of the hemostatic agent. The visible indication may be color coding, or, the marking could take the form 20%, 40%, 60% and, 80%. The hemostatic agent may be any substance assisting in hemostasis, may be in powder or fluid form, and may be one or more of Thrombin, Gelform, Fibrinogen, or other hemostatic substances. The hemostatic article could include at least one radio-opaque element which may take the form of a thread or a strip. Alternatively, a radio chip embedded in the hemostatic article may be used. The visible markings per se could be made radio-opaque, thereby obviating a separate radio-opaque element. The pretreated marked hemostatic articles are sterilized for medical use in any known manner.

A surgical instrument is configured to aid in performing a procedure of detaching an internal mammary artery (IMA) and the like, from the connecting tissues and side branch vessels which surround the artery in its native location, wherein the detaching procedure is preliminary to the performing of a coronary artery bypass grafting procedure and wherein the IMA is detached via a minimally invasive thoracotomy. To this end, an elongated slender rod includes a handle at its proximal end and an artery engaging loop, arc, fork configuration, or hook at its distal working end. Embodiments may incorporate electrosurgical capability or electrical insulation. A surgeon thus has means for harvesting an intact and undamaged graft vessel from its native location through a minimally invasive incision with enhanced speed, visibility, and freedom of motion.
