The present disclosure provides tissue matrix packaging devices and methods of use. The packaging can be used to help a tissue matrix sample retain its shape when being stored or transported.

A method for preparing a backup kit for a plurality of patient-specific arthroplasty procedures scheduled at the same medical facility includes providing a database with data from completed arthroplasty procedures using patient-specific arthroplasty kits. The database includes comparisons between preoperatively planned implant size and intraoperatively implanted implant size. The method includes determining a statistically expected implant size deviation from a planned implant size for each implant included in a plurality of patient-specific arthroplasty kits prepared for a shipment to the medical facility using the database. A backup kit of backup implants is assembled for the shipment. The number and size of the backup implants is determined from the statistically expected implant size deviations.

An assembly includes a medical device having a stent and a prosthetic valve connected to the stent. The prosthetic valve includes valve leaflets. The assembly further includes a buffer piece having a leaflet cover and a removable attaching structure. The leaflet cover protects the valve leaflets and the removable attaching structure removably attaches the buffer piece to the medical device. The buffer piece prevents contact, imprinting, abrasion, and/or damage to the valve leaflets.

A device for crimping a radially expandable and collapsible prosthetic valve comprises a crimping loop having a first end portion, a second end portion, and a loop portion extending between the first and second end portions and defining an opening configured to receive the prosthetic valve. The crimping loop is movable between a first state in which the opening has a first diameter and a second state in which the opening has a second diameter smaller than the first diameter such that when the prosthetic valve is positioned within the loop portion, movement of the crimping loop from the first state to the second state is effective to reduce a diameter of the prosthetic valve. A method for crimping a prosthetic valve comprises reducing a diameter of an opening of a crimping loop, thereby radially compressing an at least partially expanded prosthetic valve disposed within the opening.

The invention relates to an assembly comprising a transparent “outer” packaging element (1) defining a chamber, and an “inner” packaging element (2) received in said chamber of the outer packaging element (1). Said inner packaging element (2) comprises at least first and second packaging portions (21, 22) that are transparent, each of which has at least one cavity (41, 42) for receiving an article, and a sealing sheet that is at least partially opacifying, and that comprises two portions applied over the two packaging portions (21, 22) in such a manner as to close said cavities (41, 42). The two packaging portions (21, 22) of the inner packaging element (2) are folded over towards each other towards a configuration in which the two portions of said sealing sheet applied over the two packaging portions (21, 22) of the inner packaging element (2) face each other.

A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. A sheath is placed over the crimped scaffold after crimping to reduce recoil of the crimped polymer scaffold and maintain scaffold-balloon engagement relied on to hold the scaffold to the balloon when the scaffold is being delivered to a target in a body. The sheath is removed by a health professional either by removing the sheath directly or using a tube containing the catheter.

A holder for heart valve prostheses, the holder including a hub portion having a longitudinal axis, an engagement portion coupled to the hub portion and including plural L-shaped finger members variably positionable relative to the hub portion between a collapsed condition wherein the finger members are closed onto the hub portion and an expanded condition wherein the finger members radially protrude with respect to the hub portion to engage a heart valve prosthesis.

An implant is provided that is operable to be disposed between and fuse two sections of a bone. The implant includes a material that is operable to abut against the two sections of the bone. The material is porous and/or fibrous and is operable to receive at least one cellular growth factor.

A valve for endovascular heart valve repair that provides improved sealing of the valve against the native wall. The valve assembly has a sealing region at a distal end of the valve. The sealing region having a delivery position and a sealing position, wherein in the delivery position, the sealing region has a first length, and in the sealing position, the sealing region has a second length less than the first length and a thickness in the sealing position is greater in the sealing position than in the delivery position.

Described here are devices and methods for crimping self-expanding devices. The crimping devices may be useful for crimping a variety of different self-expanding devices (whether such devices are biodegradable or bio-durable). The crimping devices may have crimping members to engage the self-expanding device to reduce the device from an expanding configuration to an unexpanded configuration. The crimping member may comprise or include a suture, wire, ribbon, guiding hoop, pusher, prong, holding bar, balloon, jaws, combinations thereof, or the like. The crimping devices may also include or comprise a holding structure to hold the self-expanding device in an unexpanded or expanded configuration.
