Bioabsorbable stent

Provided is a biodegradable polymer coating stent effective in delaying the damage of physical properties (particularly radial force) of a core structure. The stent includes a core structure of a bioabsorbable material (e.g., Mg), a first coating layer of a first polymer with biodegradability, and a second coating layer of a second polymer with biodegradability, wherein the first coating layer covers the whole surface of the core structure; the second coating layer covers a part or the whole surface of the first coating layer; the first polymer has a glass transition point of lower than 37° C.; and the second polymer has a glass transition point of 47° C. or higher.

Loop vascular device and method to retrieve

The present disclosure relates to a loop vascular device and a method to retrieve said device from the body vessel of a patient. The loop vascular device comprises a loop having a first portion extending distally to a splitting portion, and a second portion also extending distally to the splitting portion, defining a close state of the loop. The splitting portion may be split such that the first portion is separated from the second portion when in the body vessel, defining an open state of the loop. In the open state, the loop may be easily retrieved through ingrowth in the body vessel, reducing or eliminating possible negative effects to the vessel wall.

Composite prosthesis with external polymeric support structure and methods of manufacturing the same
09956069 · 2018-05-01 · ·

A prosthesis including a support structure for enhancing kink and/or crush resistance. The support structure is connected to an outer surface of the prosthesis and includes at least two components, one of which has a lower melting point than the other. The component with the lower melting point is used to connect the support structure to the outer surface of the prosthesis.

Loop vascular device and method to retrieve

The present disclosure relates to a loop vascular device and a method to retrieve said device from the body vessel of a patient. The loop vascular device comprises a loop having a first portion extending distally to a first bar, and a second portion extending distally to a second bar. In a close state of the loop, the first and second bars are maintained or housed inside a first cannula. The first cannula may be in contact with a second cannula. Upon desiring to open the loop, the physician may separate the first cannula from the second cannula, allowing the bars to exit the first cannula and disconnect from each other, defining the open state of the loop. In the open state, the loop may be easily retrieved through any ingrowth in the body vessel.

Surgical Implant
20170119515 · 2017-05-04 ·

A surgical implant (1) comprises a flexible, areal basic structure (2) having a first face (3) and a second face (4) and being provided with pores (6) extending from the first face (3) to the second face (4). An absorbable film layer (10) is placed at the first face (3) of the basic structure (2), is attached to the basic structure (2) and has an outer face (12) facing away from the basic structure (2). An absorbable marker (20) is attached to the outer face (12) of the film layer (10), wherein the marker (20) is adapted to indicate an upside/downside orientation of the outer face (12) of the film layer (10) and to indicate a center area of the basic structure (2).

A FLOW DIVERTING APPARATUS FOR CHRONIC INFLAMMATION AND LYMPHEDEMA
20250073015 · 2025-03-06 ·

A flow diverting apparatus includes a stent frame body, and a stent frame extension.

The stent frame body includes an inlet opening, an outlet opening, and a cavity extending from the inlet opening to the outlet opening. The stent frame body is configured to pass a flow of fluid from the inlet opening to the outlet opening through the cavity. The stent frame body includes a first portion having the inlet opening, and a second portion having the outlet opening. The second portion is tapered from one end of the second portion to a first location of the second portion, thereby forming an indented portion having a plurality of pores. The stent frame extension is configured to be disposed between at least a portion of the indented portion and a vessel wall, thereby preventing a migration of vessel wall cells onto the indented portion.

DEVICES AND METHODS FOR TREATMENT OF THE EUSTACHIAN TUBE AND SINUS CAVITY

A polymeric stent can be implanted for treatment of the Eustachian tube. The stent can be designed to have length-dependent radial strength to allow it to stay within the Eustachian tube and to allow normal closing and opening of the Eustachian tube. A balloon can be used to implant the stent, and the balloon can be coated with a therapeutic agent. A coated balloon can also be used to transfer therapeutic agents to the sinus cavity during a balloon sinus dilation procedure.
