11583662 · 2023-02-21 · ·

Some embodiments provided herein relate to methods, systems and kits for providing consistent intracoronary administration of a biologic to subjects having diverse coronary anatomies. In some embodiments, the biologic is an adeno-associated virus serotype 1 (AAV1) vector encoding sarcoplasmic/endoplasmic reticulum ATPase 2a (SERCA2a) protein.

High concentrated protein compositions for preventing tissue adhesion

Disclosed herein is an anti-adhesion kit comprised of: (i) a fibrinogen solution component comprising: fibrinogen at a concentration of about 5 to 25 mg/ml; and free calcium ions at a concentration ranging from 0.1 μM to 1 mM; and (ii) a thrombin component containing thrombin. Further disclosed is an anti-adhesion kit comprised of: (i) a fibrinogen solution component containing fibrinogen at a concentration of 8% to 25% of total protein by weight, and optionally free calcium ions at a concentration ranging from 0.1 μM to 1 mM; wherein a total protein concentration ranges from about 80 to 120 mg/ml; and (ii) a thrombin component containing thrombin. Methods of using the kits e.g., to provide anti-adhesion curable compositions are also disclosed.

TISSUE DERIVED IMPLANTS REHYDRATABLE WHILE DISPOSED WITHIN A DEVICE

A tissue derived implant is provided having a configuration which is sized and shaped to be disposed within a reservoir of a handling or storage device, the implant having one or more liquid dispersion features for enabling effective hydration of the implant when the implant is disposed in the reservoir and contacted with a biocompatible liquid. The liquid dispersion features form at least one liquid pathway which facilitates collecting and distributing the biocompatible liquid to contact the substantially the entire implant. An implant assembly is also provided which comprises a handling or storage device comprising an elongated reservoir with the tissue derived implant disposed therein. Additionally, an implant kit is provided which comprises a handling or storage device with an elongated reservoir and the tissue derived implant having an elongated configuration sized and shaped to allow the implant to be disposed in the elongated reservoir at the time of use.

Derivatized or Rapidly Polymerizing Collagen Compositions for Tissue Augmentation Containing Nonresorbable or Slowly Resorbable Polymers

Proived herein are derivatized or rapidly polymerizing collagen compositions for tissue augmentation containing non-resorbable or slowly resorbable polymers. Also provided are methods for the preparation of the compositions, and methods for augmenting soft tissue utilizing the compositions.

Hyaluronic Acid Compositions Containing Slowly Resorbable Polymers

Provided herein are hyaluronic acid compositions comprising hyaluronic acid or modified hyaluronic acid or crosslinked hyaluronic acid and slowly resorbable particles, spheres and granules. Also provided are methods for augmenting soft tissue utilizing the compositions.

Systems and methods for forming materials in situ within a medical device

A method for forming a material in an in situ medical device by initiating polymerization of water soluble polymer precursors in an aqueous solution during or after transport of the polymerizable solution from its storage container to a space inside the in situ medical device is described. The stored aqueous solution with water soluble precursors lacks a free radical initiator which, in a powder form, is introduced into the aqueous solution during or after its transport into the space inside the in situ medical device. This storage and delivery system provides greater stability to the stored aqueous solution, allowing it to be stored at ambient temperature and providing extended shelf life over the solutions used in existing in situ polymerization systems. The flexibility to store and deliver/transport only one aqueous solution, instead of requiring the use of two different solutions, is also a benefit.

Isolated placental stem cell recruiting factors

Described herein are compositions and methods of using placental stem cell recruiting factors, more specifically, isolated placental stem cell recruiting factors. In one embodiment, isolated placental stem cell recruiting factors are delivered to a site such as a diseased or injured organ and/or body part in an amount sufficient to recruit stem cells to the site.

EXTRACELLULAR MATRIX (ECM) HYDROGEL AS A SUBMUCOSAL FLUID CUSHION

Methods are disclosed for dissecting a mucosa and a submucosa from a muscularis propria from a region of an organ of a subject, wherein the organ is not the esophagus. In some embodiments, the organ is in the gastrointestinal tract. These methods include injecting submucosally into the organ of the subject a pharmaceutical composition comprising an extracellular matrix (ECM) hydrogel to form a cushion between the submucosa and the underlying muscularis propria at the region of the organ, wherein the ECM hydrogel has the following characteristics: a) a time to 50% gelation of less than 30 minutes at a temperature of about 37° C.; b) a flow viscosity suitable for infusion into the organ; and c) a stiffness of about 10 to about 400 Pascal (Pa).

COMPOSITIONS AND METHODS FOR THE TREATMENT OF RETINAL DEGENERATION
20220354896 · 2022-11-10 ·

Presented herein are compositions and methods for generating stem cell derived retinal tissue and isolated retinal progenitor cells for use in the treatment of retinal degenerative diseases and disorders.

IN VIVO BULKING AGENT, INJECTION COMPRISING SAME, AND PREPARATION METHOD THEREFOR
20220354790 · 2022-11-10 ·

The present invention relates to an in-vivo bulking agent which can be used as a medicinal agent for prevention or treatment of at least one disease selected from the group consisting of urinary incontinence, fecal incontinence, and gastroesophageal reflux or as a filler for use in a plastic surgery procedure, and to a preparation method therefor. The in-vivo bulking agent can exhibit a bulking effect when injected into the body and particularly, is highly biocompatible because a first composition in which silicone particles are coated with a zwitterionic polymer having a surfactant property is introduced into a second composition, whereby the bulking agent can inhibit inflammatory reactions in vivo.
