  • Publication number: 20150112261
    Abstract: An apparatus provides feedback regarding the material in which tip of the apparatus is located as the tip is advanced into matter of varying resistances. The apparatus responds to a change in pressure, force, or other parameter such that when the tip reaches matter of a certain resistance, a change in the parameter is sensed. The apparatus provides a driving force to a penetrating medical device, such as a needle, when the apparatus tip encounters material of high resistance. When the apparatus tip encounters a low resistance material, no further driving force is applied to the apparatus. An inner core may be advanced into the low resistance material for deployment of a gas or a liquid as desired.

  • Publication number: 20140348896
    Abstract: Pre-polymers for use as tissue sealants and adhesives, and methods of making and using thereof are provided. The pre-polymers have flow characteristics such that they can be applied through a syringe or catheter but are sufficiently viscous to remain in place at the site of application and not run off the tissue. The pre-polymers are also sufficiently hydrophobic to resist washout by bodily fluids. The pre-polymers are stable in bodily fluids; that is the pre-polymer does not spontaneously crosslink in bodily fluids absent the presence of an intentionally applied stimulus to initiate crosslinking. Upon crosslinking, the adhesive exhibits significant adhesive strength in the presence of blood and other bodily fluids. The adhesive is sufficiently elastic that it is able to resist movement of the underlying tissue. The adhesive can provide a hemostatic seal. The adhesive is biodegradable and biocompatible, causing minimal inflammatory response.

  • Publication number: 20140227777
    Abstract: The present disclosure, among other things, describes cell rolling by 3D flow and adhesive rolling. In some embodiments, a device described herein includes a flow channel dimensioned to permit fluid flow therethrough; at least one 3D structure protruding from at least one surface of the flow channel; and at least one cell adhesion entity coated on at least part of at least one of the 3D structures, which adhesion entity interacts with a target cell brought into contact with the 3D structures by flow of a stream comprising the target cell through the flow channel such that the target cell's trajectory through the flow channel is diverted due to the interaction.

  • Publication number: 20140186312
    Abstract: The present inventions in various aspects provide elastic biodegradable polymers. In various embodiments, the polymers are formed by the reaction of a multifunctional alcohol or ether and a difunctional or higher order acid to form a pre-polymer, which is cross-linked to form the elastic biodegradable polymer. In preferred embodiments, the cross-linking is performed by functionalization of one or more OR groups on the pre-polymer backbone with vinyl, followed by photopolymerization to form the elastic biodegradable polymer composition or material. Preferably, acrylate is used to add one or more vinyls to the backbone of the pre-polymer to form an acrylated pre-polymer. In various embodiments, acrylated pre-polymers are co-polymerized with one or more acrylated co-polymers.

  • Publication number: 20140148846
    Abstract: Adhesive articles containing microtopography, such as microprotrusions, and a coating of adhesive glue, such an adhesive having known toxicity and/or tissue reactive functional groups are described herein. The articles described herein contain a substrate, a plurality of microfeatures, and an adhesive, such as an adhesive glue. The articles described herein exhibit a 90° pull off adhesion of at least about 1.5 N/cm2. The articles described herein can contain less adhesive than when the adhesive is used alone without microtopography and yet exhibit equivalent adhesive strength with little or no toxicity or other adverse side effects (e.g., exothermic reaction).

  • Publication number: 20130331792
    Abstract: The present disclosure provides devices and uses thereof. A devices disclosed herein comprises one or more tips, wherein the one or more tips are designed and constructed to initiate penetration by the device; and one or more protrusions in a region adjacent to each tip. In some embodiments, one or more protrusions can be constructed and arranged so that the required penetration force is reduced as compared with that observed for an otherwise identical device lacking the one or more protrusions. Additionally or alternatively, one or more protrusions can be constructed and arranged such that the required pull-out force is increased as compared with that observed for an otherwise identical device lacking the one or more protrusions.
